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

Code:

lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:100 errors:0 dropped:0 overruns:0 frame:0 TX packets:100 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:11166 (10.9 KiB) TX bytes:11166 (10.9 KiB) ra0 Link encap:Ethernet HWaddr 00:19:5B:6D:2F:FA inet addr:192.168.1.142 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::219:5bff:fe6d:2ffa/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:15086 errors:0 dropped:0 overruns:0 frame:0 TX packets:2867 errors:0 dropped:0 overruns:0 carrier:0 collisions:104 txqueuelen:1000 RX bytes:1949038 (1.8 MiB) TX bytes:257564 (251.5 KiB) Interrupt:11 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 ra0 cat /etc/resolv.conf domain mir.fallman.org nameserver 172.16.3.3 rt61sta.dat [Default] CountryRegion=0 CountryRegionABand=7 WirelessMode=0 SSID=nethernet NetworkType=Infra Channel=0 AuthMode=WPAPSK EncrypType=TKIP DefaultKeyID=1 Key1Type=0 Key1Str=0123456789 Key2Type=0 Key2Str= Key3Type=0 Key3Str= Key4Type=0 Key4Str= WPAPSK=secretpassword TxBurst=0 PktAggregate=0 WmmCapable=0 APSDCapable=0 APSDAC=0;0;0;0 BGProtection=0 IEEE80211H=0 TxRate=0 RTSThreshold=2347 FragThreshold=2346 RoamThreshold=75 PSMode=CAM TxPreamble=0 FastRoaming=0

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"

Code:

Do they look right?

Some more wlan info:

iwconfig

iwlist ra0 scan (nethernet is my wlan)

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.
