Firmware version is 2.00NA --- I can login a few times after causing the router to reset then all logins fail. The router has been replaced this did not help, The modem has been replaced this also did not help

What kind of setting(s) can make that happen?
UPDATE:BLAH... apparently one of the computers on this network was loaded with virus. Ran virus scan on the computers and after dozens of virus were listed for one it was shutoff (likely all the same virus just spread out on the computer). Now all is well when connecting to login.owo.com again => Maybe a virus hopped onto that computer when I re-enabled the wireless but before I had the password set?
My guess is that this virus would overload my network and the router resets that let the network run like normal for a minute or so just stopped the action(s) of the virus for a short time.
