USB wifi dongles keep locking up

Post by xgenadam » 2015/03/04 13:01:19

Hi all,

I am running CENTOS 7 and have been having this issue since install.

At seemingly random times my wifi dongle will stop working, this has been tried with 2 different dongles, the occurrence is seemingly random, at times it can go an hour without happening and at other times it will happen every 15 minutes.

when the lockup happens the signal icon in the top right shows all bars and pinging google results in host not found. So far the workaround that I have managed is simply unplugging and re plugging the devices back in will reconnect me to my network but the issue reoccurs later.

the two wifi dongles i have tried this on are:
Tp-Link TL-WN821M
ALFA model AWUS036H

any help would be appreciated.

Further Edit:
Followed this guide to ensure the correct drivers were installed and the problem has still not disappeared, there is no noticeable change rate of occurence.

This is actually starting to seriously hurt my productivity, can anyone offer some insight?
