I have a 802.11b home network on a D-Link DI-514 2.4 GHz Wireless router with one desktop and two wireless laptops. One of the laptops which I bought not to long ago (Gateway DS CX210X CTO) seems to have trouble using Wi-Fi. It has a built-in adapter which I'm letting Windows manage, with a manually assigned ip address. I can ping the loopback address and the other 2 computers on the network, and even google.com, but it won't connect to the internet otherwise (won't goto any internet sites, online games wont work, wont connect to any servers for updates, etc.). It connects to the router interface, but some pages on the web-browser interface for the router I can't get to; It will just do the Opening page blah blah blah thing for a long time and then just quit. It has Windows XP Pro w/ SP2, and the strange thing is, is if I use the administrator account that is only activated when the computer is booted in safe mode with networking, the connection works. But if I use any other account, it has problems.
Other useful information:
-The connection is WEP encrypted
-SSID Broacast is turned off
-Windows Wireless Zero Configuration says it is connected with an excellent
signal
-When I checked the network adapter status, it did show packets have been sent and received
Things I've tried and still haven't worked:
-Shutdown my firewall to see if that was preventing things
-Demilitarized the ip address
-Took out the manual configuration for the ip address and enabled DHCP on the router
-Changed the channel from 6 to 1. Still not working, so then I changed it to 11 and still not working
-Disabled Windows Zero Configuration from managing the connection and let the software that came with the adapter manage it
-Turned off the "Allow the computer to turn off this device to save power" in the Power Management section of the adapter's configuration in Device Manager
Thanks!
P.S. Of course the connection works if I disable the wi-fi adapter and connect to one of the router ports with an ethernet cord.
I'd personally stick with the Windows WZC service for card management, it ususally works best. This might sound silly but if you have a static IP did you enter the router IP for the default gateway and primary DNS settings on the laptop?
What type of wireless card does the laptop have built-in?
Almost forgot to mention: update the router firmware. Lots of 'older' SOHO wireless gear seems to have issues with those new Intel wireless cards, a firmware update often fixes this.
