sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
sudo ip link set wlp13s0 up
sudo iw dev wlp13s0 scan
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf

Just wait for 5 minutes and then restart your system.  just Wait some time the signal will comes or just restart one more time .

Note No 1:  If you still not get the strong wifi signal with your antenna 2, then  just replace antenna 2 with antenna 1 and try all steps. For that in command “sudo modprobe -v rtl8723be ant_sel=2” replace sel=2 with sel=1 like below.

sudo modprobe -v rtl8723be ant_sel=1

In command “echo “options rtl8723be ant_sel=2” | sudo tee /etc/modprobe.d/50-rtl8723be.conf” replace sel=2 with sel=1 like below

echo "options rtl8723be ant_sel=1" | sudo tee /etc/modprobe.d/50-rtl8723be.conf

And restart your system 2 times.

Note No 2: After your OS (Kernel) update, you need to apply these settings again to get strong signal. (Delete old extracted folder from desktop and Download new driver zip file and apply all the above steps)

Note No 3: Tested with Ubuntu 20.10 and Kernel 5.8 with our Downloaded drives.

Note No 4: Tested with Ubuntu 22.04 and Kernel 5.15 with build-in OS drives. (You don’t need to download and install wifi drivers from our site. Just skip the driver download, make and install steps and follow all other steps.). If antenna 2 not work then try with antenna 1. It will work.

Note No 5: It also work with older versions of Ubuntu and other Ubuntu Debian based Linux Distro.

    Thank u sm, it worked!!

  2. Himanshu Arora

    Hi, these steps are not working on my laptop, i have an ubuntu 20.04 installed, i had also faced this problem few months ago but then it works but now its not working. could you suggest something else??

    1. Manikandan

      delete old downloaded and extracted driver files and download a new copy and try again. if still not work then reply with error message and your kernel version.

      1. Himanshu Arora

        Hi Mani,
        I have completed all steps and steps are working fine, but i couldn’t get strong signal.
        My kernel version is 5.4.0-65 generic,
        Do you have any solution for this?
        Please suggest me its very important for me.

        Thanks

      2. Himanshu Arora

        Hi, now i have updated my kernel version to 5.14.0-….- generic, but still not getting strong signal after completing steps.

        1. Manikandan

          Afrer this command sudo modprobe -rv rtl8723be
          try this
          sudo modprobe -v rtl8723be ant_sel=1
          Just replace ant_sel=2 with ant_sel=1
          and also in echo “options rtl8723be ant_sel=2” | sudo tee /etc/modprobe.d/50-rtl8723be.conf
          replace antenna with 1 like this
          echo “options rtl8723be ant_sel=1” | sudo tee /etc/modprobe.d/50-rtl8723be.conf
          and finish all steps and restart your system 2 times.

          If still not working just install/overwrite with fresh kernel again or update ur kernel. (This is important)
          Also update ur os to latest.
          After that follow “For Ubuntu 21.04 (kernel 5.11) and above:” steps.
          Don’t download install driver from here.(important)
          Without installing the driver try with antenna 2 and antenna 1. It will work.

    I have rtl8723de , followed the instructions in the master branch. Signal was -81 dbm earlier, after doing the steps now I have -42dbm and speed has increased 3x !!

  12. Mauro

    I have elementary os juno and the Syntax “CD Desktop” does not work. The terminal tells me File or Directory does not exist.

  23. Pradeep Kumar Patra

    sir, i read this article how to solve weak wifi signal in ubuntu linux and i applied this setting in my system in which am i using linux mint (hp laptop). as a result i got success, this is just unbelievable and superb. thank you so much to get rid of this critical issue. i heartly thnks u. pls keep it up.

  24. Nobody

    I followed all steps, did not get any error in the meantime but my signal is still weak.
    It is very annoying.
    What should I do? Find another Linux? or wait for kernel updates to solve the issue? I am desperate I have tried like 6 advises from various sites.

  25. Nikhil

    I ran all the commands. Signal strength improved drastically. After 15 days or so, it dropped automatically. I re ran the commands, but the signal strength is not improving this time.

  26. Pao

    THANK YOU SO MUCH FOR KEEPING THIS SOLUTION UP TO DATE. YOU’RE THE BEST!

  27. Fabio

    Thanks man, This is the only solution that really works!!!! Thanks thanks thanks!!!!

  28. Scott

    I’ve previously used this solution on Ubuntu 16.04 LTS, but after the OS 18.04 upgrade, it’s no longer working.
    I’ve downloaded the new driver .zip files as instructed, but when I enter the ‘make’ command I get an error: make[1]: *** /lib/modules/4.4.0-137-generic/build: No such file or directory.
    Can anyone advise?

  29. Kishan

    After installing this, I am getting signal strength of -70 dBm. Is it good or average?

  30. Satish

    Amazing fix. thanks a lot. I was struggling with this for long and even after going through multiple forums, nothing worked. Finally, this solution worked and I am getting around 86% signal strength. Thanks a lot.

  31. Allan

    Great help, man. Working for 18.04 on a HP Notebook laptop. Thanks

  32. sreekanth

    Thanks a lot …

  34. Seenivasan

  35. Rahul

    Thank you very much man

  36. Ravneet Punia

    What do you mean by “Note No 1: After your OS (Kernel) update, you need to apply these settings again to get strong signal.”
    In my laptop, It worked fine, but once I restart all changes gone. Looks like these changes are not parmanent. Plz help!!!!!

  37. Anoop

  39. Michael

    THANKS U!!

  40. HypnoMama

    Thank you so much!!! This finally worked and I have spent hours trying all sorts of things. I have a question for you: I have linux dual booted alongside windows 10. If I am booted in linux when I close the computer or it goes to sleep and I start it back up it will be in airplane mode. I have to completely shut down/restart everytime or the wifi is hard-blocked. rfkill unblock all does not work. Not the end of the world but super annoying to constantly shut down restart. Any tips? I’ve tried a bunch of things and nothing works but you’re the only one who has posted something to solve the router issue so maybe you’d know what to do?

    Thanks so much! Have an awesome day!

  41. Joe

    Same issue as Jugnu – command ‘make’ not found. Please help!!!

  42. JUGNU KUMAR

    I have installed dual boot in my machine and i am using ubuntu 18.04 LTE alogside with windows 10. Signal is coming is very weak in ubuntu i have tried these commands but ‘make’ isn’t working i have installed the make as well but it is showing some kind of error please help me.

    1. Manish

      I’m having the same problem with 18.04. Can someone please help?????

    2. manish

      I’m having this same problem. i installed make but still its showing error. secure boot is also disabled. i don’t understand what’s wrong? is there anyway to fix this??

    3. Felipe SC

      did you solve the problem?
      I followed all the steps and it works for me. Send an email and I can help you with that.

      Pura vida.

    4. Ranjan M N

      sudo apt-get install linux-headers-generic build-essential git
      git clone https://github.com/lwfinger/rtlwifi_new
      cd rtlwifi_new
      make
      sudo make install

      use these commands and follow rest as in the tutorials.
      continue from “sudo modprobe -rv rtl8723be” as it is in this page.

  43. Gregory Horwitz

    Thank you so much! I’m baffled as to why this has to be done manually. Admittedly, I’m a genuine greenhorn when it comes to linux, but it would seem that they could automatically update drivers – especially when this wifi issue is so prevalent.

    Either way, thank you very, very much.

    How to do it for parrotlinux

  45. kiran

    Thanks bro for the solution it worked well. But my Wifi it works only if i disable the secure boot, if i enable the secure boot the wifi itself was not detected. Please let me know how can this be fixed. My laptop HP Pavilion 15-au063nr

    1. foxtreat

      i have the same laptop as you,just keep secure boot off,because microsoft is not a nice guy with linux secure boot causes alot of problems for linux most times,just keep it off

  46. marath

    Works fine but it go back after restart. the echo “options rtl8723be ant_sel=2” | sudo tee /etc/modprobe.d/50-rtl8723be.conf creates the .conf file and it stays there. but wifi weak. I’? a complete noob in linux. then just do sudo modprobe -rv rtl8723be and sudo modprobe -v rtl8723be ant_sel=2 and it is good again. OS is updated. Problem can be solved with a executable file on start but I would like to do this in a clean way.

  47. Rohit

    It works for me. I am using hp 15 laptop with ubuntu 16.04.
    Thank you 🙂

    This problem emerged after I updated the system and tried to fix this problem

    1. Manikandan

      First disable the secure boot from your BIOS setting. And download the new drivers from the download link and try.

      1. Qirxx

        I get the same mistake.
        However, when I disable Secure Boot, The only thing I see on boot is black screen. With Legacy boot turned on, it says “no boot devices found”. Is there a way to solve this?

        1. Dhawal

          Make sure you have this rtl8723be drive only for your network. There are steps shown on the github master page you can check out.

  65. Isra

    Any one has facing that on Windows reach 150 Mbps and on Linux just 72 Mbps?
    By the way, I’ve used current driver that is cimming on Ubuntu 17.10. Just have set the ant_sel=2.

  69. phigirl

    HI! i have problems with this part
    “sudo modprobe -v rtl8723be ant_sel=2” after i enter this code, it’s shows me
    “insmod /lib/modules/4.10.0-38-generic/kernel/drivers/net/wireless/realtek/rtlwifi/rtlwifi.ko
    modprobe: ERROR: could not insert ‘rtl8723be’: Required key not available”
    i don’t know what shlould i do now, because I
    have no wifi connection right now

    1. Manikandan

      Disable the secure boot from your BIOS setting. And try again.

  70. Pamela

    Hi! I tried this yeeterday and I make a mistake on my wlp.. Number, after that I cudnt conect on wifi so I installed again ubuntu but 15.04 and it worked perfectly except that I couldn’t upgraded it and again I installed Ubuntu 16.04, from this part was all perfect until i tried the code again and i hane no wifi conncetion and when i tried to reboot the Ubuntu shows me a black board with errors

  71. Rida

    Hi I tried this in the command line but the code returned error when I typed in sudo modprobe -v rtl8723be ant_sel=2. The system responded with a message saying that I do not have key or something like that and after that I lost the wireless option from my computer completely. I went from having wifi with poor signal to nothing at all and there’s no way that I can revert the changes. the rfkill list does not show the wireless option, only the bluetooth. Can you help me in any way?

    1. Manikandan

      If you get any error like ” modprobe: ERROR: could not insert ‘rtl8723be’: Required key not available”
      Then Disable the secure boot from your BIOS setting. And try again.

  72. ASHUTOSH DWIVEDI

    thanks yar. U saved me. No word to appreciate. You are just amazing

  73. Arpit Joshi

    Will this also work on ubuntu 17.10??

      1. sai kiran

        i tried it in ubuntu 17.10 it worked but when i restart my pc again wifi shows weak signal.what am i supposed to do

        1. Manikandan

          Update your OS to latest and try all again.
          Note: After your OS (Kernel) update, you need to apply these settings again to get strong signal.

          below command make the setting permanent until OS update.
          echo “options rtl8723be ant_sel=2” | sudo tee /etc/modprobe.d/50-rtl8723be.conf

  74. Gineet Mehta

    Thank you so damn much! Worked like a charm, signal strength’s up to 100% next to router (from 50%).
    Will edit and update comment after I check going here and there a little.

  75. Hazael

    Worked perfectly! thank you very much!

  76. Eric

    Hello everyone. I’m having a problem with this. When I try to open a virtual terminal, it prints this message: “[ XXXX.XXXXXX] rtlwifi: IEEE80211_AMPDU_ERR!!!!:” where are number, differents each time. What could I do? It’s something recurrent, doesn’t stop, and does’not let me work on the virtual machines.

  77. Rahul

    Hi Manikandan,

    All the above steps were successfully executed except the last one for saving changes ..it didn’t asked for my password..kindly help

    1. Manikandan

      Just restart your pc and check your wifi signal. If strong leave it. Note: And After your OS (Kernel) update, you need to apply these settings again to get strong signal.

  78. Jithin C Chacko

    Thanks……

    After entering sudo modprobe -rv rt18723be=> It shows
    modprobe: FATAL: Module rt18723be not found in directory /lib/modules/4.4.0-83-generic

    1. Manikandan

      Please first read the comments also.
      it’s not rt18723be. It is rtl8723be. Its l (L) and not 1 (one).

      If you are still facing this issue, try sudo depmod -ae and then try again to sudo modprobe -rv rtl8723be

  83. Sushil

    Problem in last command:
    /Desktop/rtlwifi_new-master $ sudo iw dev wlp9s0f0 scan
    command failed: Network is down (-100)

    1. Manikandan

      Try iwconfig in terminal and note wlp number correctly

      1. sourav

        This solution works but why its not permanent? the moment I reboot the laptop the same issue happens?

        1. Manikandan

          To make the settings permanent,type below command in terminal and press enter. (Please read all – start to end)

          echo “options rtl8723be ant_sel=2” | sudo tee /etc/modprobe.d/50-rtl8723be.conf

          1. Tasnia

            When i run “sudo ip link set wlp13s0 up” it shows me – Cannot find device “wlp13s0”
            Why it is happening?

          2. Manikandan

            In terminal type iwconfig and hit enter to find your correct wlp number.

  84. Harsh Makwana

    Wow! Great. It Works. Thanks for this kind of stuff.

  85. Piera Andrea Soto King

    thanks, the wifi it works on my laptop very well now!
    but I had a problem after this installation, my laptop started to discharge and the time that I can work with the battery is short compared with the time before that I installed it.

  86. Mahesh

  109. Josh

    Thank you very much for your help, it fixed my problem!

  110. John S

  113. Benoit

    Hi I’m new on Ubuntu. I try to do as it showed, everything’s working perfectly till I get this:

    [email protected]:~/Bureau/rtlwifi_new-rock.new_btcoex$ sudo modprobe -rv rtl8723be
    [email protected]:~/Bureau/rtlwifi_new-rock.new_btcoex$ sudo modprobe -v rtl8723be ant_sel=2
    insmod /lib/modules/4.4.0-64-generic/kernel/drivers/net/wireless/realtek/rtlwifi/rtlwifi.ko
    modprobe: ERROR: could not insert ‘rtl8723be’: Required key not available

    Any idea about the modprobe error?
    Thanks by advance

    1. Manikandan

      Disable the secure boot from your BIOS setting. And try

      1. Benoit

        Thanks a lot Manikandan. It’s work perfectly. As I told you, I’m new on Linux system and now I can say it’s true that Linux Community can help you when you’ve got problem, and I’m really happy to say that ant not coming back to Apple or worst windows!!!!!!!

  114. Mike

    Be sure to disable secure boot while you do this or you may encounter errors, you can use: sudo mokutil –disable-validation then reboot to finish disabling the secure boot

  115. nikhil

    me getting
    error at time of install
    error- install: missing file operand
    what should i do

  116. James

    This was outdated info before it was posted. No need for the rock new btcoex branch since Larry merged that with master branch in March 2016. Any distro that uses kernel 4.4 and newer already has the antenna parameter

    1. John S

      Maybe in master branch but I was running current kernel and it wasn’t fixed. This is the only thing that fixed it. Maybe certain PC’s have a issue that only this solves?

  117. Anupam Wadhwa

    Awesone….
    Salute you man…

  118. Nabeel

    I love you, it worked.

  119. Noor Jaber

    Thank you, it is working perfectly.

  120. Paul

    How do I do the same for OpenSUSE Leap 42.1?

  121. OB

    Thank you so much! I was seriously considering going back to windows since my wifi had a weak signal and kept disconnecting, but now its working as well as when I had windows installed. Works with antergos/arch also, just may need to download linux header files when using make command

  122. AleoOte

    You are the best!!!! Thanks a lot!!!

  123. Gambit

    God bless you.
    you saved my life.

  124. Kaushik L V

    Thank you so much!!!! I would have tried atleast 10 other solutions and spend hours and hours on this problem and finally your solution(and such a simple one) has solved it 🙂 🙂 Once again thanks a lot! 🙂

  125. Enyi-Christopher Joshua

    Thanks Man… I have been trying to fix this for days now. Thanks a lot

  126. Mehul

    Thank you so much bro. Life saver seriously

  127. Kikerinkata

    Thank you

  128. kyle

    I have a RTL8101E network adapter on my new HP. Not seeing any files for this make, I went for it to see if the RTL8723be would work. After making it past the two “sudo modprobe” commands, I found that my network connection was terminated, and iwconfig listed no “wlo1” as it did before. Learning my lesson, how can I revert, or undo these changes? Thank you

    1. Vinis

      try to set ant_sel=2 to “ant_sel=1”

      1. giri

        My network connection is terminated too and It doesn’t work even after the kernel update. Is there any way to revert back the changes

  129. Archie

    This was a life saver.
    Thank you so much for sharing it.
    I wonder why they havent included it by default in the distro.
    Anyways, it works fine now just wanted to know if I can delete the folder from desktop?

    Can I now remove the folder from the desktop??

  130. jua ma

    Hello
    Thanks a lot for your help
    Now, could you help me with the Realtek Realtek RTL2832P chip, that is inside a Astrometa DVB-T/T2 tuner? Some drivers are available online and it appears installed in Ubuntu but the device never works. (It is 0k because it works under windows).

    Thank you

  131. LS

    thanks… I have to change some things, but it works… 🙂

  132. Mark

    When I type in:

    sudo modprobe -rv rt18723be

    I get the following error:

    modprobe: FATAL: Module rt18723be not found.

    Any advice?

    1. Manikandan

      try sudo depmod -ae and then try again to sudo modprobe -rv rtl8723be

    2. Dinesh

      it’s not rt18723be. It is rtl8723be. You are writing1 instead of l as in L.

  133. Manish

    hi. could you please tell me how to install this drive on kde neon? please

  134. sanjeev

    I just got a new HP laptop with free dos OS, I had installed ubuntu 16.10, everything was fine but wifi had a weak signal problem. With your instructions, that problem solved too. thank you, you saved my time and effort. great job

  135. don dougall

    Update to previous post – the problem returned after a couple of reboots. Will look into kernel issues as mentioned to Ailien.

    1. Manikandan

      Hi don, try to upgrade your kernel version and update all available soft updates to latest. Then try the fix.

  136. don dougall

    Bless you my saviour. You have no idea how many days I spent trying to dual boot Mint 18 on an hp laptop when the wifi connection simply was erratic on MInt but fine on W10.

  137. rishabh

    hatsoff dude worked like a charm

  138. boopathi

    when i typed that cd rtlwifi… then enter it says no file or directory

  139. Allan

    Why has this driver not been rolled up into the distro?

  140. NOman Ansari

    thanks alot, it worked for me perfectly.

  141. Anvita

    Hey Manikandan! It worked perfectly for me. Thank you so much!
    I use Ubuntu 16.04 LTS on Lenovo Flex 2.

  142. Sudu

    That’s a really awesome fix..! Thanks a lot buddy..!!

  143. Robert

    Hello Manikandan, just wanted give you a big thank you for the instructions ! Everything works well now =)

  144. Life

    After trying this command,
    “sudo modprobe -rv rtl8723be”

    I get this..

    libkmod: ERROR ../libkmod/libkmod-config.c:635 kmod_config_parse: /etc/modprobe.d/rtlbetcoex.conf line 1: ignoring bad line starting with ‘options’

    1. philwar1095

      Me too!!! PLEASE HELP!

      1. Manikandan

        Download from here restart your pc and try again. If you still facing that error then try to open the rtlbetcoex.conf file, locate the bad line, delete it, and save the file. Retart and try again.

  145. Damien

    Thank you very much 🙂 recently set up a dual boot to do some work and really needed to be able to use this at school (which I couldn’t because of the very weak signal reception). This was a really really big help. I just applied this and will keep monitoring to see if it sticks but in either case: great and easy to follow guide!

  146. al

    Worked for me the firts time but after the reboot it stopped working… when i try tyo do it again it still dont work and my wifi conections aren’t working

  147. ladeb

    thanx man

  148. Thangasivam

    Nandri Manikandan. Helped a lot. Step by step procedure was awesome. A kubuntu user.

  149. AIlien

    When I type “make” in rtlwifi_new-rock.new_btcoex directory it returns the following error:

    error: initialization from incompatible pointer type [-Werror]
    .flush = rtl_op_flush,
    ^

    and then:
    error: (near initialization for ‘rtl_ops.flush’) [-Werror]

    So I can not continue with the whole process. My laptop is a HP 250 G4.

    Thanks anyway 🙂

      1. Ailien

        Hi Manikandan,

        I did it but the problem persist. I even reinstalled Ubuntu and repeated the process but it didn’t work. However, I tried to compile the file in another laptop (Linux Mint 17.2 Rafaela) and it didn’t return any error. So I’m confused and start to think that it is a problem of Ubuntu distribution or configuration :/.

        Thank you for your time

          1. Ailien

            It worked! Thanks a lot 🙂

  150. Mohit

    DUDE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    You ARE AWESOME!!!!!!!
    REALLY WORKED!!!!!!

    1. Mohit

      Worked Even IN KALI Linux
      HP AB032TX
      THANKS!

  151. Vikas

    Thanks Manikandan, it really helped. But I faced prob;em again after the updates I had to repeat the above steps. Could you suggest a shortcut for that.

    1. Swarnendu

      Having the same issue..did you find a solution ??

    2. Nicolás

      As he said in the article: “After your OS (Kernel) update, you need to apply these settings again to get strong signal”

      Hope this gets fixed on future kernel updates :S
