Wireless Connection Seen But Not Connected

Hi everyone I have been struggling with this problem for a while. I am
running Fedora Core 6 on an IBM Thinkpad R60. I installed the ieee80211
sub-system and the wireless drivers (and firmware) for the Intel Pro
Wireless 3945abg card. I can see multiple wireless networks with
"ipwlist scan" but can't seem to connect to any of them. The following
is the results of "iwlist scan" -- the top network it finds is mine:

This is the output of iwconfig:

I have a static IP set with the correct subnet mask and default
gateway. When I was trying to use DHCP, I was getting "link not found"
when trying to make the connection active. With the static IP it says
the connection is active (and the daemon starts on computer start-up)
but I can't connect to my wireless network, even though I can see it.
Any help would be appreciated, and let me know if you need any more
information. Thanks!

Did you note that all networks use the same channel 6 ? So they may disturb
each other. What happens, if you move your network to another channel (
best either 1 or 11 ) ?

Markus, changing the channel didn't seem to help. Also, if it means
anything, it works fine when I boot the computer into the WinXP OS.
Thanks to you both for your help!!

If the above is correct, then here's your problem. You're trying to
connect to a non-existant network. Take a look at your ESSIDs. These
two networks are not identical:

"The E Network" // From iwlist
"The E-Network" // From iwconfig

Notice that you're trying to connect to a network with a dash in the
network name, while the network that really exists does not have a dash.

Make sure you tell your wireless adapter to connect to "The E Network".

From the command line, as root:

# iwconfig eth1 essid "The E Network"
# ifconfig eth1 up

That doesn't look right. Both interfaces are on the 192.168.1.???
network. You'll either need to adjust one of the addresses or both
netmasks so that the two interfaces are on different networks. (Which
is easier and more suitable depends on the rest of your network setup.)

And there you see the two routes to the same network: one over eth0 and
one over eth1.
