I have a unique dial-up setup for a remote LAN. My LAN consists of Aironet wireless products and a Cisco1602 R router. This LAN is not a standard LAN as it has no PC connected to it. The host stations consist of GPS devices and Lantronix IP servers. The GPS devices send data ever 10 seconds via the WLAN to my NOC. The router connects to the Internet via a Dial-up line. My problem is, that my router keeps disconnecting. Most of the time it will reconnect but on a few occasions it has had to be touched my a remote operator (myself) via telnet or consol to get it to reconnect.
Why does it keep disconnecting?
