Hello,

I just built my new computer and I'm having an issue I've never had in my life. Randomly and with no patterns whatsoever, my access to the internet (on Google Chrome or any other browser) cuts off. If I try loading any page, it loads as 'connecting' and then soon fails to connect. Meanwhile, my applications such as Hearthstone (a game) or League of Legends (another game) will be running completely fine as if internet is working properly. This is an issue with only my computer and no other devices. My phone and my laptop will work perfectly fine as if there is no issue at all.

I have no idea how to start investigating this so I thought you kind gentleman or ladies might be able to help.

If you could comment below what more information you need to assist in resolving this issue, I will gladly provide you with them.

Thank you!



Some information:

Computer Specifications (useless but why not):
-i7 4790K
-8GB RAM
-128GB SSD
-GTX 780
-Windows 8 Professional

Router:
ASUS RTN56U
http://www.asus.com/Networking/RTN56U/

Wireless Adapter:
ASUS USB-AC56R
I tried looking for this adapter on the ASUS website but apparently it doesn't exist.

Important Notes:
-I don't think it's my wireless adapter that is the problem. I also have an internal N56 wireless adapter built into my computer as well and switching to that didn't fix the problem.
-I have Bitdefender total security installed on my computer. It has something called 'game mode' and currently it is on 'auto-pilot mode.' From the last time this issue occured, Bitdefender was on 'game mode.' I fixed the issue by turning off 'game mode' (I have no clue if 'game mode' is relevant considering this happens so rarely and randomly that I never kept track) and then restarting my computer (this happened just now).


Thank you!

It is likely the browser cache even though it is strange that multiple browsers are affected at the same time.

So first step open a command window and try NSLOOKUP for a number of the sites you are trying to reach. See if you get a ip address.

Next you can use the telnet command to test. You will likely have to "install" the telnet command since microsoft likes to disable this by default.

What you do is telnet to the site xxx.xxx.com 80
This connects to the http connection (port 80) like a browser does. If you type GET you sometime get a bunch of junk. The key here is not so much what you get but that it connects. You will have to try telnet to some other ip or ports to see how it looks different. It is hard to describe but...

If you can telnet to port 80 then it has to be the browser. I would be looking to wipe all the stored/cached data and make sure nothing has been messing with the proxy settings. If telnet also fails then I would be looking at firewall setting that stopping you.
