Today I've encountered a really strange wifi bug. Basically, everything is running fine until I get really non-responsive internet. The wifi icon in gnome shows 'connected', but Chrome does not load pages and just times out.

Next time this happened, I ran a ping to google DNS and got really long response times, like 30000 ms range. I decided to leave ping running while I work. Suddenly, this happened:


I checked journalctl - nothing. My OS is Arch Linux, uname -a:

Linux 4.4.5-1-ARCH #1 SMP PREEMPT Thu Mar 10 07:38:19 CET 2016 x86_64 GNU/Linux

Laptop is Dell Latitude e7450 with an Intel wifi card.

Network controller: Intel Corporation Wireless 7265 (rev 59)

lsmod | grep 'wifi'
iwlwifi               163840  1 iwlmvm
cfg80211              483328  3 iwlwifi,mac80211,iwlmvm

Any idea what may cause this and how to debug it?

  • Please don't post images of text. paste the actual text (or, in this case, a smal sample of it). Also, how do you manage your connection?

  • Sorry about image, I'll edit it when I'll be on my PC. I use Gnome and it's front-end for NetworkManager.

This issue appears to be resolved after changing my wifi rotuer from 11bgn mode to 11bg.
