Internet Slower than Ever/Disconnects/Cannot Renew Ip/Question Marks

[ddrake]

Hey everyone.

Well just recent I have noticed that I'm facing quite a few different problems. I'm not sure if it could be related to a newly installed WRT120N Linksys router or not because 2 other desktop computers in my household that are connected to it work perfectly fine.

Basically, my internet browser, Firefox, "lags" more than usual and has a very slow response time compared to normal. It takes awhile sometimes just to google search something. It should be quick (other 2 computer's internet connection working blazing fast) but it's not. (Speedtest shows that I should have around 20mb/s downloading speed, but actual use shows otherwise, as it is incredibly slow.) For some reason, Internet Explorer seems to outperform my Firefox too. And yes, I have also tried reinstalling Firefox.

At the same time, every few hours or so, my internet disconnects and the "Limited or no connectivity" warning shows at the bottom.

In addition to that, when I try to repair the connection, I can't because I get the error "Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address" , so I'm unable to renew my IP too.

My ipconfig/all shows funky information too -which I will post at the end of the post.

So far, I have tried a few things but have failed at fixing my internet connection. I have these methods already:

"
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log
"

And they both have not fixed my problems.

I know for sure there's a problem, as my computer was working fine a few weeks ago. After looking/trying out different ideas, I still failed. I hope someone can help me out! Thanks in advance.

P.S. Ipconfig shows question marks too.

Try turning off IPv6 if you don't need it.
