Trying to get wireless working

jspaceman · 07-21-2006, 08:18 PM

I installed Ubuntu 6.06 on my laptop and I'm trying to get it working with my Intel Pro Wireless 3945 mini-PCI card. I have a Netgear WAG302 access point in a room next door which handles the wireless traffic and forwards it to my Netgear FVS-318 router, which handles DHCP.

I installed the windows drivers for my wifi card using ndiswrapper, the signal strength is good, and the card seems to get an IP address from my router (192.168.0.5). But I am unable to ping anything on the network. I temporarily disabled WPA security on the access point, but I'm still unable to ping anything. My access point's log shows that the wireless card is associated with my wireless network.

I'm fairly new to Ubuntu (having used Slackware before), but I think I installed everything properly (ndiswrapper already comes with Ubuntu, right? and I installed wpa_supplicant, afterwards).

Does anybody know what I'm doing wrong?

Have you tried bringing up the interface with

Code:

sudo ifup wlan0

(where wlan0 is your interface) ?
If you get something like 'interface not found/known' try adding

Code:

auto wlan0
iface wlan0 inet dhcp

to /etc/network/interfaces and then try ifup. (again, substitute wlan0 w/ you iface name, if it is different).

I think I'm having the same problem as this guy, although it looks as though he solved his problem (unfortunately he didn't post how he solved it other than to say the problem was with some configuration utilities). But I'm getting the same message when I try to get an IP address from my router:

I never get an IP address and I'm unable to ping anything on my LAN. And when I type 'dmesg' I get:
