Ubuntu 20.04. Wifi TPLink extender issue

  • 772

I have a laptop with Ubuntu 20.04. I can connect to my main WIFI signal, but cannot connect to TP Link WiFi extender. The same laptop with Windows 10 (dual boot) works fine. Other devices like tablets, ipads or phones are connected to this extender normally. Only in Ubuntu 20.04 is the problem. Thanks in advance for any suggestion.

  1. Today I faced a similar problem after switching over to Linux from Windows 10. Windows, my phone, consoles, etc were all able to connect to my TP-Link extender, but my Linux installation couldn't. I found your thread and was dismayed to find it had no solution, but as I managed to fix the problem for myself, I thought I'd post what worked for me here.

    After a while of searching, I decided to try changing the DHCP client. I installed the package dhcpd5 from the repositories and then used a text editor to open the file /etc/NetworkManager/NetworkManager.conf.

    Underneath the header [main], I added the line dhcp=dhcpd.

    I ran sudo systemctl stop NetworkManager.service, then sudo systemctl start NetworkManager.service. I was then able to connect, and a speed test indicates the WiFi network is working properly.

    Hope this helps!

  2. I also faced the same problem. I checked /var/log/syslog and found there a suspicious warning dhcp4 (...): request timed out. So I tried the suggestion to add to /etc/NetworkManager/NetworkManager.conf the line dhcp=dhcpcd and it didn't work for me. But adding instead dhcp=dhclient did work.

  3. I also faced the same problem. In my case, the previous solution didn't work (installing dhcpd5 and adding the line in NetworkManager.conf).

    On top of that, I did apply the steps suggested in this link (which ironically seems to get info from AskUbuntu) and that worked. I copy the steps here just in case they help somebody else:

    git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

  4. Thanks bimblesticks, the solution outlined by you works for me with Comfast wifi extender. I had restart the system to get working. And you have dhcpd in your comment that need to be replaced with dhcpcd as package name is dhcpcd5.
