very weak signal for old routers, can't connect at all for new routers with intel 7260 wifi adapter

br flag

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.

Is your router set to auto channel select (bad) or a fixed channel (good)?

Does running `sudo systemctl restart NetworkManager` improve your wifi signal?

@stumblebee unfortunately no. I will update my post accordingly

Do you have administrative access to the router? Check there.

@chili555 I checked and it is automatic. However, I do not think that this is the problem, as my laptop used to work with these routers before. Also, I cannot change the settings of the router everywhere where I use my laptop, so I need to find a way to make it work whhen the router is set to auto. All other laptops can manage, so I guess mine could too.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
