Dell Latitude D620 Intel PRO Wireless 3945ABG Linksys WRT54G (Tomato Firmware) MAC Filtering WPA Personal, AES Wired ethernet works fine, my inspiron 600m works fine. watching the router i see the D620 pop up on the device list but not DHCP an IP the router logs look like this DHCPDISCOVER XX:XX:XX:XX:XX:XX DHCPOFFER 192.168.X.X so the router sees the card and offers it an address, the card never sends a DHCPREQUEST to the router i've verified the WPA key a million times and the MAC address in the filter list... i've updated the drivers to the latest 3/2008 version, rebooted, no dice tried using the intel wireless manager, etc i tried setting the encryption from AES to TKIP i've shut off MAC filtering i've disabled wireless security and still the same thing... DHCP server sees MAC and makes IP offer, laptop never does anything... BUT only over wireless... the wired ethernet does the whole DHCP handshake and goes online this laptop was just working the other week when i had it home from work... any suggestions? I am considering backing out the tomato firmware to see if it makes a difference.. |

this morning i did a restore to defaults (including NVRAM) and on the laptop i deleted all of the preferred networks from the list... one by one i turned on WPA, used an easy key, then turned on MAC filtering, then changed the easy key to the strong key i use, then i changed the SSID from the default to the one i use... and now it's connected... unfortunately the other laptop i was using to troubleshoot the wireless doesn't have firefox on it so the NVRAM dump and configuration backup didn't work (my only gripe with tomato is that most of the cool features seem to only work in firefox)... my priority was getting the system back online ASAP so i could work from home today (D620 is my work laptop)... troubleshooting wasn't... i believe that a bad WPA key or incorrect encryption type was cached somewhere... if i could have dumped the router NVRAM i would have seen it router side... i don't know where stupid windows keeps that crap... all is well now... firefox is installed... and my good configuration file has been saved off...

I'm guessing the firmware didn't take. Put a standard image on it and try again. I flashed a bunch of enterprise HP Procurve APs one time, and one of them wouldn't forward DHCPOFFERs, nor would it accept the encryption from the wireless clients. I re-flashed with another image and it was fine. |
