Windows 7: Internet traffic connectivity lost

Internet traffic connectivity lost

Hoping someone can shed some light on a lost internet connection please.
System is Acer 5336 Windows 7 64 -bit with ie9 browser.
Browser has been acting slow to open web pages and displays 'cannot open web page' quite frequently.
Decided to uninstall ie9 via Progs & Features etc and assumed ie would default to ie8 as suggested by some websites.
Wrong! Or in this case anyway...I have lost all internet connection.
So this is what I've tried so far:
System Restore
Reset Router (Netgear DG834GT)
Rebooted Router & factory reset
Checked all cables & filters - all ok
Opened Network sharing center - disabled & enabled LAN & Wireless network connection.
Ran CMD - netsh in tip reset c:\resetlog.txt to reset TCP/IP
So the network gateway,DG834GT Router, is I'm assuming accessible but Windows can't receive traffic from Internet!?!
Finally,ran Network Adaptor Troubleshooter which informed me:
The Wireless connection doesn't have a valid IP configuration.

So, I'm wondering if it's as simple as IE having been 'Lost' from my system or a missing Router path.
Any ideas will be very welcome.

Make sure you have it enabled:

You can't connect via internet explorer or any other browser to the internet?

System Restore wont work so could you try an sfc /scannow in command prompt window

You could try a repair install

Did you try typing internet explorer, internet, or ie into the search bar (provided you have it enabled. If you don't, then look for it in programs)?

Thanks for the advice DustSailor...I appreciate the time and thought.
After 5 days and a lot of swearing I finally found the culprit.
MS had downloaded 3 critical updates which had knocked out the IE link and
created a problem for the router; Ive not come across this one before so
wasn't really looking for it.
Have altered updates to be notified before downloading in future.
Once again, many happy.
