Comment 10 for bug 477212

This bug seems to be fixed in Maverick (at least for me). NM shows connection speed as 54 Mbps (using WPA2 TKIP/AES) and my internet connection (10/10 Mbps through 1 Gbps router) is only slightly faster when using ethernet.

This bug was a huge problem starting from Karmic/Lucid with my A-Link USB WLAN adapter but since then I've switched back to ethernet. But as for those who use this chipset/driver, this shouldn't be a problem under Maverick.

Please report back if this problem still occurs in Maverick and/or Natty!
