My wifi signal is extremely weak since I reinstalled my operating system. I need to stay very close to the router in order to make it work.
I have Ubuntu 22.04.1 LTS, an Intel 7260 wireless adapter, kernel 5.15.0-52-generic, firmware version: 17.3216344376.0 7260-17.ucode.
For all the details of my setup, here is the result of the wireless info script found here: https://pastebin.ubuntu.com/p/r8tJ55GqMY/
I tried some solutions found here, but so far, none of them worked. I tried to modify iwlwifi configuration (11n_disable=1, power_save=0, bt_coex_active=0, swcrypto=1) as described here. I also tried to blacklist modules as described here.
It seems that a lot of people have the same problem, and sitll I have not found a definitive solution.
EDIT: My computer cannot connect at all to networks with more modern routers, even if signal strength is strong. So I can see the network and its signal strength but can't connect. It seems that I can only connect to older router models and with low distance.
Restarting network manager by sudo systemctl restart NetworkManager
did not solve my problem either.
sudo systemctl restart NetworkManager
