network will not work properly after having run TCP optimizer, but safe mode settings work perfectly. how to restore?

Question

I was experiencing some issues with my connection while playing online and I tried to optimize it by running TCP optimizer on my PC (Windows 7 64bit professional). I thought maybe the situation could improve. but it didn't.

actually, I now get an extremely slow page loading time, probably due to a very low RWIN value of 1024. I understand that Windows 7 has a system to automatically adjust the RWIN value when needed. The setting from netsh is "normal" so I guess something else must be wrong.

I tried every automatic tool out there to restore Windows' default values, but I had no success. I currently have what should be labeled as "default values" for everything TCP Optimizer initially changed, but the problem persists.

The thing is, I just found out that running Windows in safe mode SOLVES the problem completely. The problem is that as soon as I reboot, I get the same issue all over again.

So my question is: is there a way to use SAFE MODE network settings in NORMAL mode?

Try running the following command in an elevated command prompt (right click "Command Prompt", choose Run As Administrator):

netsh winsock reset

If that doesn't work, try restoring to a date before you ran the optimizer using System Restore.

==EDIT==

I found some more ideas. Try running the following command in an elevated command prompt:

netsh int ip reset

followed by netsh winsock reset, then reboot.

If you still have issues, try:

netsh int tcp set global autotuninglevel=Normal
netsh int tcp set global congestionprovider=default
netsh int tcp set heuristics default
netsh int tcp set global ecncapability=default
netsh int tcp set global dca=disabled
