Frequent internet access dropping - "Limited Internet Access"

First things first, these are my computer specs.

Operating system: Windows 7 Ultimate 64 bit
System Manufacturer: Gigabyte Technology
System model: GA-770TA-UD3
BIOS: Award Modular BIOS v6.00PG
Processor: AMD Phenom II X4 955 Processor ~3.2GHz
Memory: 4096MB RAM
Display: ATI Radeon HD 5670
Netword Adaptors: D-Link DWA-552 XtremeN Desktop Adaptor (wireless)
& Realtek PCIe GBE Family Controller (on board - disabled)
Wireless Router

I never had this issue on Windows Vista, occasionally my internet will randomly dropout. Limited Internet Access". When it does I can do a few things to get it working again:
- Disable, then enable my wireless card and reconnect.
- Uninstall the card, then re-install and reconnect.
- Disconnect from the internet myself and reconnect.

Either way it gets super frustrating. There is 1 other computer plugged directly into the router that does not experience any issues. In addition, I have 1 laptop (windows 7) that works great and 1 laptop (Windows XP) which works great.

For any technical suggestions, please clarify how to perform what the recommendation is, I'm not too keen with networking issues.

Thank you

I not router expert but I do have a suggestion. Shut down completely your computer and router. Start both again and go to here.
Speed Test | Bandwidth | Broadband Internet Services
Test all the computers and see how close they are to each other.

The computer has internet connection fine, just once in a while (maybe 10x a day) I get no internet access
