Public bug reported: I bought a TP-Link WN 350GD PCI Wifi Card with an Atheros chip. It worked well on Natty and Oneiric, until a few weeks ago (probably after a kernel upgrade) when it started acting funky. It's connected to the router alright, but the internet's either disconnected, or very very slow - slower than dialup. Signal strength's good at 77%, authenticated via WPA2-Personal.
I'm using both LAN and Wireless connections (LAN's routing is enabled) since LAN connection's for the internal network, while the wireless connection's for the Internet. I can usually scan and ping other devices/workstations connected wirelessly but not anymore. Every now and then, the wifi card would allow me to connect to a website at 15K- 20Kbps, but it'll disconnect soon after. Syslog shows that the card keeps on re-authenticating to the network. Something that does not happen on my TP-Link USB Wifi with Ralink chipset - and they're averaging at 65%-75% signal strength. I've already tried booting to v2.6.39, v3.0.0-15, and v3.2.1 (which I got from kernel.ubuntu.com for precise pangolin) kernels with no success. I've even tried compiling compat-wireless by following the instructions on http://linuxwireless.org/en/users/Download#Directly_downloading_the_tarball I've also commented out ath_pci from /etc/modprobe.d/blacklist-ath_pci.conf all with the same result. I haven't tried using wicd as suggested in the forum since it doesn't support simultaneous connections So is this an ath5k bug? or did my pci wifi card went south. I can't replace it at the moment since this is a company workstation and might take a while to get a replacement card. By the way, the workstation I'm using is a dev workstation and a web/database/ntpd server for our prototypes which means it's on 24/7.
