I just recently switched from Windstream (bonded T1) service to Comcast cable. Everything was working fine, except the SonicWall NSA 2400 drops WAN every 10 minutes. The only way to get the internet back is to reboot the sonicwall or disconnect/reconnect the ethernet cable from the sonicwall to the comcast modem...but it only stay on for 10 minutes and drops again. There were never these issues with the Windstream T1.....Any ideas???
