Windows 7: Network Card Issue - Extremely weird.

Windows 7 Ultimate 64bit
Network Card Issue - Extremely weird.

Hi guys,

I will try and explain my situation as clearly as possible from the get go so there isn't a ton of probing questions that need to be asked.

My computer specs are:
Operating System: Windows 7 Ultimate 64-Bit (6.1, Build 7601)
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: GA-770TA-UD3
BIOS: Award Modular BIOS v6.00PG
Processor: AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz
Memory: 4096MB RAM
Display: ATI Radeon 5670, 2805MB
Network Card: D-Link Xtreme N Desktop PCI Adapter DWA-552 w/ latest driver v. 1.70

My Situation:
Right now, everything works great. But, every time I restart my PC; my network card wont connect to the router. The SSID is displayed with full bars, however when I try to connect I recieve "limited connectivity" and get the error
"Windows is unable to connect" -

From here I need to re-install my network card.

Here's the weird part:
As I'm uninstalling the network card, my connection is quickly restored to perfect functionality for 5-10 seconds until the un-installation completes. When I re-install everything it works great... until I reboot my PC.

Side note:
- When I formatted my computer, this issue wasn't happening. I began installing all my windows updates then it started again.

This makes me wonder if there's a Windows Update that is interfering with your network card driver. It's a pain, but you could start uninstalling the networking-related updates one-by-one ("Programs and Features/View Installed Updates") (reboot after uninstalling each one to check the issue). If it's an update, the issue will be resolved after you've uninstalled the right one(s). Or you could format/reinstall again and then update one-by-one, rebooting in between each, and see which one breaks it and uninstall that one.
