My wireless 4-port router is connected to my DSL modem. The router seems is properly configured for the ISP's specific ip settings and I can browse the Internet when my laptop is connected via Ethernet cable.
However, my problem comes when I disconnect the cable from the laptop and enable the wireless. My laptop connects wirelessly to the router (confirmed by SSID, WEP encryption, and the deletion of the neighbor's SSID) with strong signal, yet I cannot browse the Internet. I can't connect to the router's HTML configuration page, it seems it can't get out to the DSL modem. In "Network Connections", all the properties for Local Area Connection and Wireless Network Connection seem to be the same.
The most confusing part is that our home's other laptop connects wirelessly to the router and browses the Internet without any problem whatsoever. When I view its Wireless Network Connection properties, nothing seems strangely different from that of the laptop with the problem. It does not matter if the bad laptop is wired or wireless, the good laptop always works.
The router is set to allow up to 16 clients. It is giving sequential ip addresses to the wired connection, the wireless connection, and the good laptop.
I use Windows XP Pro SP2, Buffalo AirStation WBR2-G54 Router, Dell Wireless 1350 WLAN Mini-PCI Card and the troubled laptop is a Dell Latitue d810.
Thanks in advance for your help. I hope this is an easy fix for someone.
