That is rather odd. You could try unplugging your router and plugging it back in or reconfigure it with wpa or remove WPA for a bit just to see if it will connect but idk I’m not a network person so I’m not entirely sure what you would do to get it to work This person had a similar issue https://forums.gentoo.org/viewtopic-t-962280-view-previous.html?sid=748ef0420b4562a0964c6711bf7c01cd
It ended up being something in their WPA_supplicant.conf file.
Is your router wep or WPA?
Might also look into setting up a static IP, or just to eliminate any configuration issues you could try a fresh build and only install the driver and then try connecting through wicd-curses.
