I've just finished building my first ever machine using 11.10, and everything has gone swimmingly except for one small thing.
I'm using a TP link TL-WN821N USB dongle to connect to wifi, which connected to my network out of the box, however at seemingly random intervals it loses speed down to 1mb/s and then needs to be unplugged and plugged back in. it happens more frequently when streaming media.
Any tips to make it more stable? The driver is using is ath9k_htc.
Hope someone can help!
