Can connect to WPA network, can't connect to unencrypted network

Running a T61p.  netcfg2 is great, was a breeze to set up, and quickly made friends with my WPA-enabled router.  Life is good.

... until I try to connect to unencrypted networks, whether in my building, my office, a coffee shop -- no dice.  It says it's "DONE", the essid is assigned, and ifconfig reports good news, but there's no network.  Works fine either way under Windows.  I've tried using a netcfg profile with SECURITY set to "none", "", "None", the entire line commented out.  I've tried removing net-profiles as a loaded module and rigging my network manually to no effect.

What could I do wrong that it works perfectly with a WPA-encrypted router but not at all with a completely unsecured router?

ifconfig reports good news, but there's no network.

A little unclear there - does that mean you get an IP address? If so, how do you establish that there's "no network"? Can you ping domain names? IP addresses? What does your routing table look like?

Re: Can connect to WPA network, can't connect to unencrypted network

I get an IP address, I can't ping any domain names, I can't ping IP addresses, web pages don't load,  basics like telnet don't connect, and the routing table looks like:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
192.168.0.0     *               255.255.255.0   U     0      0        0 wlan0
default         192.168.0.1     0.0.0.0         UG    0      0        0 wlan0

Can you ping your router? Is your /etc/resolv.conf OK? Post the iwconfig/ifconfig output.
