[SOLVED] Thinkpad T590 doesn't connect with wifi extenders enabled ?

[QuowLord]

I have a Thinkpad T590 that I got about a year ago, and it refuses to connect to my school's guest WiFi network. This network works fine with a friend's laptop (also running Windows 10), and was working previously on mine, but began connecting intermittently, and then eventually not at all. The issue happens in both Fedora Linux and Windows 10 (I dual boot), and Windows troubleshooter reports the issue as "rapidly connecting and disconnecting from the network," or some such similar complaint about excessive roaming between the access points. I had a similar issue with Apple devices when we had a range extender in our house, which we removed for that reason. It appears that this issue is a hardware issue, since it happens in both OSes, but I don't want to ship it to Lenovo for warranty service if I don't have to. Is there anything else I can try?

I think the issue can be related to the WiFi adapter in the laptop either failing or that the drivers might've gotten corrupt. You might want to see if the laptop has any BIOS updates pending. Following that, make sure you're on the latest OS version(20H2) and that the drivers for your laptop are reinstalled in an elevated command, i.e, Right click installer>Run as Administrator.

You might want to have the laptop looked at in case you will need to open it up, which might void the warranty, unless Lenovo state otherwise or that you know what to look for when the laptop is opened up.

Does your laptop work with other WiFi network? For example your with your phone as Hotspot?

I should mention that it works with other networks, such as my home network, as long as there is no range extender.

Bios updates were installed a few days ago and didn't fix the issue. I'll try updating Windows drivers next, and see if I can find Linux drivers.

BIOS and driver updates didn't help

For some reason Lenovo's automatic update utility found some firmware updates or something that I hadn't found, and now Linux and Windows work fine. Huh.
