Some Wifi networks don't work

[akoidan]

Hey,

Did you issues that some wifi networks when you connect as a client. Some of them work and some? devices in this networks can't be ping and internet don't work. I can't find a factor that causes a wifi network to not working. Sometimes it connect

E.g. one of the caffe's networks (SSID TerraMare) don't work from my laptop, but works perfectly from a mobile device or any other friend's devices (or windows from this laptop).

But I can't access anything in the network, even can't ping the router.

Some authorization with that networks times out and it can't connect like in this thread

Some networks work smoothly.

I tried switching from wpa_supplicant to iwd but it didn't help.

My system: Asus Zenbook s13 UM5302TA.310 WIfi card: MT7922 802.11ax Archlinux bleeding edge KDE + Network manager. All packages defaulted Kernel from this repo.

I've never had the problem you describe. Perhaps you should consider replacing the MT7922 with an AX200/AX210. 😢

@akoidan Yes I had the same experience. But I am not sure if we face the same situation.

I also went to a cafe with the public wifi. After the connection is successful there is no connection prompt page pop out. After checking ifconfigI found that the assigned IP is totally wrong (I got 172.X.X.X but my phone got 192.X.X.X). It only happen with kernel 6.2+.

After rebooting my laptop and select 6.1.X kernel, the assigned IP is correct. Still up to date I didn't know why and also I didn't check all 6.2 and 6.3 kernel so I am not sure what causes the problem.

But based on your post date I guess you were not using kernel 6.2+ so I am not sure we got the same problem. Also I guess you can boot using the kernel that comes with the original linux release, and see if that helps.

Kernel 6.1 (Correct IP address)

$ uname -r

Kernel 6.3 (Wrong IP address)

$ uname -r
6.3.7-060307-generic

$ ifconfig wlp1s0
wlp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

Both are connecting to the same access point but got different IP ranges. Kernel 6.1 got the correct IP address but Kernel 6.3 got the wrong address. And due to the wrong assigned IP the public wifi login page didn't show up.

@latin-1 Did you replace MT7922?

@akoidan I find an old Intel 8265 wifi card from my old laptop and replaced the Wifi card.

Seems my laptop wifi connectivity and the network speed is more stable now. Hope all those weird behavior would gone. Just wonder if the laptop would have better wifi connectivity by replacing Intel 8265 with Intel AX200/AX210.
