Wifi not working - mt7925e

dankza · 2025-05-14 15:23:57

I’ve been experiencing frequent and unpredictable Wi-Fi issues on my Arch Linux laptop. Connections will randomly drop—often showing 0 B/s throughput—and sometimes entire networks don’t even appear when I’m at friends’ houses (I can no longer see any 5 GHz SSIDs). In cases where the SSID is visible, the connection attempt fails despite using the correct password. Any insights into what might be causing this or how to debug further would be greatly appreciated.

System Information

[]Kernel: Linux archlinux 6.14.4-arch1-2 #1 SMP PREEMPT_DYNAMIC Tue, 29 Apr 2025 09:23:13 +0000 x86_64 GNU/Linux
[]Network Controller: MEDIATEK Corp. Device [14c3:7925] (driver: mt7925e)
[]Firmware package: linux-firmware 20250508.788aadc8-1
[]NetworkManager version: nmcli tool, version 1.52.0-1

Issue Details

[]Intermittent drops: data rate falls to 0 B/s and both ping to gateway and Internet hosts fail.
[]Sometimes networks are not visible at all (e.g., at friends’ houses).
[]When visible, some SSIDs refuse connection despite correct WPA-PSK (4-way handshake timeouts).
[]Cannot see any 5 GHz networks at all.

ChatGPT gave me a script to help debug my issue and this is the output :

- Yes and when i run this and rerun my script it still says power save is on,

I also added wifi-powersave-off.conf and wifi_rand_mac.conf to etc/NetworkManager/conf.d , however they dont seem to take effect even after rebooting or restarting network manager

I also added

I will add this once I see the drop however this is the journal output for the moment, hopefully something in here stands out
pastebin : https://pastebin.com/qbXpFmCw

Apologies for using pastebin, I couldnt upload the journal output here due to formatting issue.

Edit: i realised i put the wrong driver in this file /boot/loader/entries/2025-05-02_14-03-04_linux.conf , when disabling pcie_aspm however now that has been updated

If you uploaded it to 0x0.st you could have shared that link - no need to copy around the internet.

Disable the iwd.service.
If you want to use iwd as NM backend, see https://wiki.archlinux.org/title/Networ … Fi_backend and do NOT use https://wiki.archlinux.org/title/Iwd#En … figuration

my bad for some reason i though that was local, but will do for in future

Disable the iwd.service.

I havent disconnected randomly so far so i think this may have been the fix however i still cant see my 5G network at home, any idea where the issue could be coming from ?
I used to be able to connect to my 5G network at home however after messing around with some potential fixes (before your help), i can no longer see it.

You might want to elaborate on those. Do scans still find other 5GHz APs? (you could eg. try your phone)

yes my phone and other laptop can connect to my 5Ghz Wifi and this laptop also used to connect. I think when i was trying to fix my other issue I broke something and now it can no longer find the 5GHz AP.

On another note i thought disabling iwd fixed my network connection issues however I just went down. The way to fix it is to disconnect and reconnect to the wifi. Here is the log

No, I meant if you turn your phone into a 5GHz AP, can you still detect that?

You connect, sleep the system (disconnects and connects because of that) and 8 minutes later draw the journal and reconnect the wifi.
I assume you lost the connection during those 8 minutes?
Is suspending to RAM a necessary prerequisite to cause this?

There's a stalling scan and

May 15 19:06:48 archlinux wpa_supplicant[712]: bgscan simple: Failed to enable signal strength monitoring

I guess the scan issue is related to the "losses" - you could try whether the connection remains stable if you lock in the BSSID until we figured what's wrong w/ the 5GHz scan (or maybe scanning at all?)
https://wiki.archlinux.org/title/Networ … ts_(Wi-Fi)

You still have "pcie_aspm=off mt7925e.disable_aspm=Y", have you tried w/o that (after disabling the conflicting iwd.service)?
