Hello, I registered here because other topics on this forum in my endless Googling were the most helpful... and yet the problem persists.  The last couple days I had a problem where my internet would drop on boot, and that was the entire internet.  Oddly, it also disconnected every device on my network.  I fixed the problem with netsh winsock reset which fixed the issue until the next reboot when it would start all over again.  Today I encountered a totally different issue: I could now connect to IPs, but I can't connect to DNS, and resetting winsock no longer helps.  Every other device on the network now works perfectly again, no more drops.  Pinging IP's in the command prompt also doesn't work.  Pinging 8.8.8.8 returns four counts of "Request timed out."  nslookup works for both IP's and domain names.

 

I'm running Windows 7, 64-bit, with a TL-WN822N adapter and DIR-655 router

 

The only changes I can think of right before the issues started is the installation of Visual Studio 2010, XNA Game Studio 4.0, and TortoiseSVN

 

List of things I've tried:

 

*Flush DNS, renew DNS

*Reset winsock

*Set IPv4 manually to connect to my router's DNS, Google's DNS, and OpenDNS

*Set IPv4 to automatically get DNS again

*Malware scan and virus scan

*Ran CCleaner on the registry

*Disabled DNS Client Service, and enabled it again

*Restarted DNScache

*Disabled all firewalls

*Tried to tether with my phone through EasyTether, gave me another error message about connecting to DNS

*Rebooted like 50 times

*Restarted the router, both through the wireless controls and by unplugging, then factory reset the router

*Drivers up to date, and reinstalled

*Checked my HOSTS file

*Connected to another router, and still had the issue

*Ran nbtstat -R

*Changed DHCP range to force new IPs

*probably other things, I've had a busy day with this

 

Only thing I haven't really done is test with another adapter.  In theory the phone would serve that purpose but I don't trust that much.  Unfortunately I have no other adapter to test with atm.

 

Not sure if worth noting, but at one point AVG decided rundll32 was a threat and asked me to virus vault it and in my frustration I did it by habit.  It's restored now, but could AVG picking it up as a threat be indicative of a larger problem?

 

Here is my ipconfg:

Obviously all the common sense solutions aren't working so feel free to lay anything on me.  Thanks in advance.

Hey guys, running a system restore fixed my problem.  Guess I'll never know what the issue is, but hopefully it won't come back.

AVG has caused several issues for people who have been using it latley, uninstalling it always fixed the issue. Ecspecially with email and not displaying because of the HTML standard and not text in the body.

From your IP config your DNS server is your router.  If you want to change to use Google's 8.8.8.8 your best bet would be to change it on the router.  You can check out Steve Gibson's DNS Benchmark to see what is the best DNS server for you.  I will tell you that using your router normally doesn't give the best results.
