The GuitarTricks data pump is so strong here, I had to turn off "Excessive Session Detection" because the ATT 2wire modem would turn off and recycle thinking there was data flow attack!
I couldn't figure that out for a while. Contacted ATT, no help. Had a tech in our home, no help. After months of searching around, I discovered the fix online in some obscure forum, buried in a whole bunch of junk, whew. Smokin' hot connection now!
The setting is in the firewall/advanced section of the 2wire control panel if anybody else has the issue!
Check your firewall for Excessive Session Detection and turn it off! If you have a good antivirus program that does real-time protection, you should be safe.
