Symantec Block Verizon Router 192.168.1.1 for 30 minutes

I have the same common error that SEP blocks Verizon Router 192.168.1.1. My SEP version is 11.0.6005.562. When I tried to uninstall it requires password which I did not have when I installed 2 yrs ago. I need help with Cleanwipe to uninstall this SEP, so that I can try a newer version of 12.1.

With this recent version, I can't modify or change setting as you suggested in the Forum regards this issue.

Thanks,

Hanson
