Looking for a little assistance. I have a Dell E1405- just over a year old. Installed with XP when it came then had a vista upgrade from Dell. Vista was in place for 9 months and used wi-fi (public) and home DSL LAN connections for a long time. Several months ago, both wireless and cable stopped working suddenly. Had not changed any settings or installed anything further. I have a cable modem that works fine with a desktop with XP. When I plug in to the cable modem to my laptop (vista) - I get a limited connectivity - Only local connection and no connection to the internet.I have lurked on lots of forums for support. Have reset network adaptor, run the diagnostics through the network and sharing center multiple timex I uninstalled all Norton.I reinstalled vista.I reinstalled vista again with a clean/format install after backing up my drive.I have a Broadcom 440x 10/10. I have disabled it and re-enabled it mutliple times.Wireless- Intel PRO/Wireless 3945ABGI took it to Geek Squad. They recommended reinstalling Vista (which I did).My ipconfig:Wirelss Lan: DisconnectedEthernet adapater LAN: Connection-specific DNS Suffix: Link-local IPv6 Address: fe80::58ca:fc3a:a79e:c9a7%8 IPv4 Address : 169.254.1.1 Subnet Mask 255.255.0.0 Default Gateway: 169.254.2.2Tunnel Adapter Local Area Connection*6 Connection Specific DNS Suffix: Link Local IPv6 Address: fe80::5efe:169.254.1.1%11 Default Gateway:Tunnel Adapter Local Area Connection& 7: Media State : Media DisconnectedTwo issues: 1.

I have an HP and Toshiba Laptops running Vista that had flawless wireless connections to a D-Link router using WPA2 for about a year. Several weeks ago there were several Vista Automatic updates, I began experiencing connection dropouts. It was the recent batch of updates that included that "additional" patch to check for "authentic" Microsoft software...(Vista needs many other issues corrected before worrying about that one IMHO). After those last few rounds of updates, it started dropping connections. It "seems" as though it is dropping whenever the WPA2 keys were switching.About a month or two ago, I spent an entire day or two figuring out why I couldn't establish a RDP connections after several updates installed. It turned out to be the network AutoTuning that had been turned on in Vista. I turned it off using: netsh interface tcp set global autotuning=disabledand RDP started working just fine again.Today, I disabled the Network Receive Scaling using: netsh interface tcp set global rss=disabledSo far, it "appears" to have fixed the dropped connection issue when using WPA2. It has stayed connected for several hours, which is the best it's been in a week.
