My once trusty Linksys WRT54GS decided to fry itself a few days ago for no apparent reason (just a blinking light in front to plaintively cry for help). I decided this was a fine excuse to get the D-Link DGL-4300 "gaming router", since does the whole not-quite-802.11n thing as well as having a 4-port gig-E switch, which might get me faster access to my file server.
Anyway, the computer and file server are happy. My wife's laptop (Dell Inspiron 600m) sees the wireless and does the DHCP properly and works exactly as you'd hop. My laptop, however (IBM/Lenovo X41 Tablet with the Atheros a/b/g chipset), has a weird problem. It sees the wireless, and the base station sees its MAC address (implying that I typed in the WEP key correctly). However, it gets no response from the DHCP server. I set a static IP address, but I still don't get any response from the network. Packets leave the laptop and never come back. I also tried disabling all the "Super-G" stuff, but that didn't make any difference.
Any ideas for other things to try?
EDIT: I tried re-entering the WEP key. This time, everything actually worked. *Sigh*
