I am reinstalling my Debian system with the Wheezy netinstall image on a USB drive.
I have a wireless router that also comes with ethernet ports, so I could either connect to my LAN via wifi OR ethernet.
The installer was able to detect my wireless (wlan0) and wired (eth0) interfaces, but one of the following always happens:
(1) If I try network autoconfiguration for eth0, the process would always fail at the DHCP autoconfigure step (i.e. can't get IP address?). Please note that this works on the machine, before the re-install I am attempting.
(2) If I try network autoconfiguration for wlan0, it successfully authenticates with my wifi network via WPA2, and configures DHCP successfully. However, I get an error saying there is no "default route" setup. What does "default route" mean?
I have tried to cancel/delete all DHCP leases and restarting my router to no avail. I also tried getting into the shell (which is ash) but there's no ifconfig etc. that I could access.
Can anyone help with troubleshooting this problem? I am eager to reinstall Debian Wheezy soon. Thanks!
