# Windows – Extremely high ping on just one computer

So, something very weird is happening to me…here are the facts:

• Before I moved to this place, my internet connection was running
perfectly.
pages, but download speed is as expected ( 1 MB/sec on a 10 Mbps
bandwidth)
• Finally managed to trick my pc into loading speedtest.net by using
USB tethering, and my ping using my ISP's connection turned up to be
These results are consistent throughout multiple tests on multiple
servers. Also, testing my speed using USB tethering showed normal
results.

Now, the funny part is that I'm the only one in this house experiencing these problems, the rest can firstly open speedtest.net and have a ping of ~20-30 ms.
I've also tried using LAN instead of wireless, but with no change.

Here's the result of ipconfig /all:

Also, by using inSSIDer, I can see that there are no other wireless networks broadcasting on the same channels as my router is using.

Any ideas/solutions are highly welcome as I have absolutely no idea why this is happening..

I have a really similar problem but I was told that it might be malware etc and i checked with malwareBytes, bitDefender and other anti virus programs.

But I'm still having this issue, I have one other computer in the same network which shows no problems related to this.

I even tried to boot this computer in safe mode and the problem goes away.

I've suspicious that it might be a web traffic filtering virus that somehow delays my internet connection (only http or https) because in some games I play the ping is like 50 ms but in http traffic ping goes like 1900 ms which is nuts.

My internet is supposed to be 4 mbps but in this computer i only get 2 mbps downloaod and 0.10 uploaod which is crazy considering my other computer connected to the same modem gets 0.60 mbps upload.

By the way this started about a month or two ago.
