Connection Problem - Need Help!

[Ironman5000]

I'm at a loose end here I need some advice or point me in the right direction please, I would appreciate any suggestions because I really don't want to pay for some IT guy to attempt this - I have had the same issue happen before, had not one but two "professionals" run all sorts of tests and even restore factory settings but they couldn't fix it...turns out the BT desktop help tool managed to fix it by some miracle but this time it won't work...it crashes when testing the connection :facepalm:

 

The symptoms;

• When playing online games (MMORPGs) I can play for like 5-10 mins than it will disconnect, but my connection shows to have internet access at normal speed.
• There is a problem loading websites, some load very slow or not at all
• Images on websites sometimes wont load
• Speed test sites either 1) give a very low upload speed, 2) cannot run an upload speed test, 3) time out before starting. It appears to be random.

I am certain the problem is with the cpu itself NOT the router or provider as every other device works perfectly, and I know it's because I installed Norton protection as it happened immediately after. Needless to say I uninstalled it and used the Norton removal tool to make sure it has gone completely but the connection is still wonky and I can't wrap my head around a fix despite trying many common solutions found in related forums...well at least the ones which actually load for me, and some "Fixed" suggestions led me to blank MS support pages which I assume were outdated.

 

Things I tried to no avail;

• Tested in safe mode with networking, no change
• Reset the router
• Connecting the modem directly the motherboard, bypassing the router
• Disabled firewall and MSE, no fix
• Manually enabled inbound rules for the online games, not fixed
• Tried some command prompt suggestion like flush dns and checking for dodgy dlls

There may be other things I left out but it's been nearly 2 months and I forget. I suspect the problem is to do with Norton messing around with my windows firewall settings as I remember the first time this happened BT desktop helper solved the problem after it notified me it was interacting with the firewall, however because the program can no longer complete the fix and I have no idea what to do with the advanced firewall settings I am completely lost and could use some advice, thanks.

Have you tried resetting Windows Firewall http://www.thewindowsclub.com/reset-windows-firewall-settings

Yep a few times, forgot to mention that.

Try using something like CCleaner to clean the registry. Might be some lingering settings giving you grief.

 

What operating system?

Sorry for being so obvious, but it sounds like an OS reinstall would've been less hassle. Or have you tried that as well?

 

If that is more hassle, try booting from a Linux Live CD (checking that it has the right drivers). This will exclude any hardware faults.

It's Win7, just tried CCleaner it didn't fix anything.

I've never messed around with OS before and tbh I don't trust myself to do that on my own, but i'm pretty sure it's not hardware because it's an issue that was previously fixed once before using BT's diagnosis tool which says to me it's a settings problem probably caused by Norton sticking it's beak in everywhere.

OK my bad, it WAS the router after all.
