I have an open, unsecured router which I can connect to without any issues while in Windows.

When I am in Ubuntu, if I click on my wireless manager to see all the networks, then it shows all the secured networks around me but does not show my unsecured one.

I looked all over the place for a setting that could maybe filter out open networks and not show them. But I did not find anything. I do not know what is going on.

I often use the networks at Starbucks and hotels because I travel a lot. This is going to be a big problem for me. Can someone please point me in some direction?

I am using Ubuntu 10.04 with all updates applied and installed. I'm also using a Hawkings Wireless USB card. It uses the rt73 drivers that come installed default.

You might need to change the broadcasting channel, most routers have a setting for that. To figure out what channel to pick, look at the output of nm-tool, and of sudo iwlist wlan0 channel. – mikewhatever May 15 '12 at 4:23
I've tried to change the channel already I didn't think to mention that. Still didn't help. – Screaming Midget May 15 '12 at 4:33
You are not hiding the SSID of that router/WAP, are you? – irrational John May 16 '12 at 0:46

Try connecting from the terminal and setting your IP manually

iwconfig [interface] mode managed key open
iwconfig [interface] essid [ESSID]

Set your IP Address ifconfig [interface] [IP address] netmask [subnetmask]

Add ip of router as default gateway route add default gw [IP of default gateway]

Configure dns echo nameserver [IP address of DNS server] >> /etc/resolve.conf
