Description of problem:
An Encore ENUWI-G2 wireless USB adapter, which contains the Realtek RTL8187B chipset, fails to hold a connection for more than about 5 to 10 minutes. NetworkManager still recognizes it as connected, but no packets appear to go through.

kernel-2.6.27.7-134.fc10.i686

How reproducible:
Every time.

Steps to Reproduce:
1. Plug in adapter, connect with NetworkManager
2. Connect to a network, start utilizing
  
Actual results:
Dies after about 7 to 10 minutes.

Expected results:
Connection stays active.

Can you re-check this with the latest kernel?

I'm using 2.6.27.9-159.fc10.i686 and getting slightly different results.

Now the connection stays up, and associated, but no packets can go through at all.

Even if I reconnect, it's still dead as a dodo.

If it's the same for you on the latest kernel I'll upload logs etc.

Strangely it seems to have no problem associating with the wireless network, still thinks its connected, and gets an IP address... but I can't even ping the default gateway or any other ip address on the network.

I *can* ping its external ip address on wlan0

Actually, 2.6.27.9-159.fc10.i686 seems to be working perfectly fine for me.
Comment 9 Ian Weller 2009-01-13 04:44:59 UTC 
Connection sharing with this adapter now seems to work according to NetworkManager, however a kerneloops.org message box pops up after I do it. This only happened the first time, though.

Will actually test connection sharing tomorrow when I have access to another wireless machine.

Glad to hear it. If it ends up working for you best close this bug, and I'll raise a new one.
