I have a client that lives in a rural area and connects to a wireless ISP, when she connects to the office via pptp vpn she gets disconnected every 9 minutes, give or take 30 seconds.
ISP uses Tranzeo radios. In her house she uses a wireless laptop connected to a wrt54gl running dd-wrt 23 sp2.
Her office is running server 2003 for remote access behind a sonicwall tz170.
To see if the problem was her laptop I tried using the dd-wrt pptp client to connect and left it run overnight. Server logs show drops approx every 9 minutes. I then tried using the dd-wrt client to connect to a different server at my office. Same thing the vpn drops every 9 minutes.
Something is kicking her off, the only thing I can think of is a weather radar station located a few miles away. Could this be the culprit? Anyone have any ideas as to what else could be causing this?
