connection woes

[Geoffrey Leach <geoff hughes net>]

I'm having all sorts of grief connecting via wireless between two local 
systems, with a Netgear router in the middle. 

I'm running NetworkManager-0.7.1-1.fc10.i386. The Fedora 10 
installation is vanilla.

Here's the setup with the connection completed. The USB wireless uses 
a rtl8187. Here's the lsmod


rtl8187                41216  0 
mac80211              173668  1 rtl8187
eeprom_93cx6            5888  1 rtl8187
cfg80211               23816  2 rtl8187,mac80211

I should probably mention that the rtl8187 has trouble with hibernate/
thaw, so its removed and restored in the hibernation process, which 
takes place at least daily. FWIW, once established, the connection is 
solid.

The only thing that's strange about the network setup is that eth0 is 
_not_ managed by NetworkManager -- its dedicated to a TV tuner. wlan0 
is (needless to say) managed.

I'd really like to debug this situation. Or :-) find a solution.

Any thoughts? Thanks.
