That means it didn't like your WPA key. Have you tried temporarily disabling the wireless encryption and see if it works that way? That will eliminate any driver or compatibility issues. However, it doesn't hurt to be sure. Have you checked the firmware version of the CVG824G v3 to make sure it's the latest? I had to upgrade some old Netgear WGR614 router firmware in order to get Windoze 7 to connect with WPA-PSK-TKIP. Same with checking for Windoze and Dell updates. Use the ethernet cable. Any chance your Netgear router has a MAC address filter setup? If so, you'll never get a connection. Add you laptop MAC address to the allowed list and try again. Windoze has various utilties that will show wireless connection progress. For example, here are the instructions for XP. <http://support.microsoft.com/kb/328601 > <http://technet.microsoft.com/en-us/library/bb457018.aspx> When you disclose your operating system, I'll try to find the instructions. >I have tried sitting in the same room, less than a >metre from the router, the Dell shows 5 bars of signal strength but it >won't get itself an IP. > >The netbook was issued by child's school for use in the classroom and >at home.

Hmmm.... if the laptop is able to connect with other wireless routers, there must be something "incompatible" with your Netgear setup or firmware. My guess would be Netgear firmware or Windoze updates. Also, I've noticed that many of the school laptops floating around here have never been updated. When I asked, the user proclaimed that the school doesn't allow users to add or update programs. Sigh. >And because the router has worked fine for more than a year with every >other wireless device we can throw at it I don't want to change >anything there either. I don't think anything is broken. However, Microsoft does change timing and protocols with every major release of Windoze. Windoze 7 may require a firmware update of the Netgear. I can't tell because the CVG824G v3 is a cable router and the Netgear site does not offer any info on this router in the US. Maybe check with your cable provider. >An ideas or magical incantations will be appreciated. Call the cable provider. It's their router and probably their problem. -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

One more. Vista introduced a DHCP client problem, which causes DHCP failures like you described. <http://support.microsoft.com/kb/928233> This is NOT a problem in XP or Windoze 7. -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
