Hello everyone...I've never imagined myself actually posting foir help, but I'm at the point that i don't know what else to do...I own a Dell Inspiron 1420.. Which i recently formatted.The first thing i tried to install was the driver for my Intel(R) Wireless WiFi Link 4965AGN. So i can get Online and continue restoring my system..I installed the driver right off of my Dell Resource CD, for Drivers and Utilities..I tried to connect to my router, and BOOM, I got that error, Windows cannot connect to SDS-Network, which is my network.. note: The issue is not my router, my wife's laptop connects, and so does my other pc that has a wireless card in it.. + my laptop gets the same error for every other network in the area... and there are quite a few.Moving on,I went to dell.com, and tried with the drivers from them after entering my Service Tag: 621KLD1.. same issue..Tried with the same drivers, but for XP instead of Vista..same issue..Went to intel.com, got their drivers..same issue..I also saw a thread online, about someone with the same problem, but his problem was fixed by going into the card's advanced properties and and changing a setting to disabled, i forget which setting it was, but i did try that also, and..same issue..I also tried something I also saw online about some registry entry thing that was missing, and that didn't work either..same issue.I am quite desperate... I need my laptop for work, i am a web developer, and without connection, i can't work. Please.. if anybody knows the deal or is willing to help, any help will be greatly appreciated..

Hi, Hope the following Microsoft Knowledge article can help you. Error message when you try to connect to an ad hoc connection from a Windows Vista-based computer: "Windows cannot connect to <Network Name>" http://support.microsoft.com/kb/946481/en-us If not, please try to ping other computer on the network, does it work? At same time, please run the command ipconfig /all and post the result here. Thank you for your cooperation. Hope it helps.

I have two HP 8510w laptops (one I've been using for about a year and another that is a replacement for a faulty unit) Both are running Windows Vista and have the same spec (except for the hard drive size) Laptop 1 (old one) = connects fine to all my wireless networks - at home and at work (Linksys WAG160N, WRT300N). Laptop 2 (new one) = I have updated all my network drivers, Windows updates, everything and it connects to router at the office (WAG160N) but not the one at home and a various other locations. Itsees all available networks, andit prompts me to enter the passwordbut when I do it gives me "Windows cannot connect to <network name>" error. I have even triedmy sparewireless router - linksys 54 - and Laptop 1 connects fine while Laptop 2 doesn't. I have tried WEP, WAP, no security -no luck. I have tried updating drivers from HP website, Intel website - no luck. I did all HP update & Windows updates - no luck I tried matching the driver of the old laptop's network card to the new one - no luck I have tried this :http://support.microsoft.com/kb/928233/ -No luck I have tried changing the channels on my router - no luck Firm ware on my router - completely updated I have tried Hardware Profile change / disable for the WLAN in Control Panel>Admin Access> Service>WLAN - no luck I have tried setting a static IP on the TCP/IP v4 - I couldn't ping myself Tried disabling TCP/IP v6 - no luck Updated BIOs and tried Restore Defaults setting in the BIOS - no luck. Ipconfig / all - does not show IP address for Wireless lan I tried manually entering the networkd details (SSID/security settings etc) - no luck I have tried re-installing Vista Ultimate 4 times (using the Driver DVD that came with the laptop) - no luck Since it is a brand new laptop, I haven't installed anyvirus software, but I tried disabling all windows firewall etc - still no luck. I REALLY need to connect to the net at home wirelessly - and I can't seem to find a solution for it anywhere on the net. I have read that it could be an Intel 4965AGN wireless network adapter / vista compatibility issue... but if that were the case both laptops should fail to work.. I can't understand how two laptops with same spec (but slightly different drivers - as the drivers don't really auto-update themselves) work so differently. Please help!!!
