Can't use WiFi with TP Link RE305 Extender

[Blister]

I have a laptop with Manjaro KDE 20.0.3. 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 Manjaro 20.0.3 and Ubuntu 20.04 is the problem.

I see the TPLink extender Signal on my Networks, I connect with this network, but the network can't connect to internet...at the same time other devices like phones or TV are connected without problems. The same laptop with windows works fine, the issue is only with new versions of the distros. The problem is only with TPlink extender, I can connect fine to my main WiFi signal.

Anyone know what could I do?

@Blister

Only in Ubuntu 20.04 is the problem

Are you asking for help with Ubuntu or Manjaro? if the former, they have their own forums. If the latter, then please help us help you and provide information about your system:

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

Hi,
Thank you for your answer.
I've edited the Ubuntu reference, it was an error.
By the other hand, tomorrow I'll insert the log information, I'm newbie at Linux, what kind of logs should I post?

[Yochanan]

The following from the link I posted would be a good start:

First no matter what the problem , provide the hardware and software with inxi --full --verbosity=7 --filter --no-host

$ inxi --full --verbosity=7 --filter --no-host

[tbg]

Perhaps try to "disable MAC Address randomization ". If you search those terms on the forum you should easily be able to find instructions on how to do that.

[Blister]

Nothing... I've introduced:

echo -e "[device]\nwifi.scan-rand-mac-address=no" | sudo tee /etc/NetworkManager/conf.d/disable-random-mac.conf

but it's still not working.

Any suggestions?

[tbg]

Did you reboot after issuing the command?

[Blister]

Sure, I've rebooted the laptop after issuing the command.

[tbg]

You should also reboot the router/AP.

Well then I would go through the settings on your range extender AP and change the settings. Be sure no IP or MAC filtering is in place. Lower the chanel and bandwidth on the 5 GHz band to 40 or below.

Be sure your firmware on the AP is up to date and if settings changes do not work you should reset the AP to the factory defaults. It is irrelevant if other devices or OS's connect to the AP correctly, some Wifi adapters in Linux are finicky on the settings used in the AP.

Router Setup and Troubleshooting Tips

Router Setup and Troubleshooting Tips: Before jumping into the full list, reboot your router and your PC/laptop, as they periodically need refreshing to work properly. Test your routers channel and frequency settings to get the best signal strength. Switching your wireless channel can eliminate frequency interference. Installing an Android app on your phone such as "WiFiAnalyzer" (Open Source), may help you determine the best channel to use. Select a channel with the least networks and the hi…

Hi,
I've tried to reboot and to reset to factory on my Extender but it's still not working...

[tbg]

Did you change the the 5 GHz chanel and bandwidth settings (if you are using the 5 GHz band).

[Blister]

Do you mean doing so on the router or repeater?
