I ramble (if you've read any of my other help threads), so I'll keep this short.

OS - 12.04

Model - Linksys WMP300N

Proven to work - Sorta. Firmware release by Broadcom is out, but is pretty poor.

Chipset - US. Brcm4321 chipset

Problem - Horrible download speeds ( <400KB/s. Should be 2-4MB/s). Webpages take forever to load. Connection will drop under 3/4 bar conditions. Causes frequent system halts(Could be graphics card). Won't connect now. Says SSID is wrong.
