Wierd wlan Issue!

I have a Dlink card with the ralink RT61 chipset. I have compiled drivers and they seem to work fine.

I can ping my wlan router and even ping my gateway server. I cannot however reach beyond to the internet. I have been at this for hours now and I am simply clueless as to what causes this! I have two other computers that uses the wlan router and gateway already so I these two has to be correctly configured.

In other words there has to be something with the laptap / RT61 card wlan(?).

This is my current setup:

latptop < - WLAN - > wlan router < - cable -> gateway < - cable - > internet
192.168.1.142 192.168.1.2 192.168.1.1 f00

Any ideas what can be causing this? I can, as I wrote, ping the gateway and all local IPs. But somehow I cant get out! And I have had numerous different computers hooked up to the local network - both wired an wireless, neither has ever before had any issues getting out on the internet. So this has to do with my Ubuntu laptop I am truing to configure now somehow.

Thanks! Id be extremely grateful for any replies!

----------------------------------------------------------------

The day after I posted this I booted up and suddenly nothing works at all anymore!

Yesterday I managed to get LAN access by deleting some stuff from routing but I am not sure. Route is what I suspect is what is causing mischief.

My route looks like this:

Code:

192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
192.168.1.0     *               255.255.255.0   U     0      0        0 ra0
default         192.168.1.1     0.0.0.0         UG    0      0        0 ra0
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth0

The "default" is something I added because it was supposed to help. But now it comes back everytime I restart ra0 even thou I have done a "sudo route del default"x2

Detailed Rotuing with "route -nNvee -FC"

iwlist ra0 bitrate

Code:

ra0       unknown bit-rate information.
          Current Bit Rate=54 Mb/s

sudo ifup | ifdown ra0 (only with sudo gives these errors)

Code:

Error for wireless request "Set Encode" (8B2A) :
    SET failed on device ra0 ; Network is down.
Error for wireless request "Set ESSID" (8B1A) :
    SET failed on device ra0 ; Network is down.

Yesterday LAN worked and I was connected through the wlan router. Today nothing works. I havent changed the settings beside messed with around with the route command. So the rest of the settings should be right ... or?

I would so much appreciate some light on this because I am completely and utterly clueless.

"iwconfig ra0 essid nethernet" 3. "iwconfig ra0 channel 6" 3. "iwconfig ra0 mode managed" 5. "dhclient ra0" __________________ the sun is new every day (heraclitus)
