Wierd wlan Issue!

[stormfrog]

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:

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:

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

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

    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.

welcome to the forum

Cell 05 - Address: 00:17:9A:F1:F8:95
ESSID:"nethernet"
Mode:Managed
Channel:6
Encryption key:on
Bit Rates:1 Mb/s

here's some ideas
1. turn off encryption until you get a connection
2. "iwconfig ra0 essid nethernet"
3. "iwconfig ra0 channel 6"
3. "iwconfig ra0 mode managed"
5. "dhclient ra0"
