Dell Inspiron 600m laptop, SUSE 11.2, Broadcom b43 driver, using Network Manager, with a Belkin N+ wireless router.
My wireless works well most of the time, BUT the connection occasionally drops. It may be after a period of inactivity. Sometimes, it happens while I’m actively using it.
For what it’s worth, I have no problems with two other laptops, one Windows XP and one Windows 7, using the same router.
When it’s working (after boot):
mark@linux-wpmp:~> dmesg | grep firmware

When it drops, I see a disconnected wireless icon in the gnome panel. When the wireless connection has failed:

Now, if I right-click the Network Manager (version 0.7.1), Select edit connections,
Select wireless tab in the Network Connections window,
Left-click my wireless [my ssid], and ENTER,
The Editing [my ssid] window comes up, click Apply,
This re-establishes the connection, and a Bug Buddy window opens
