I acquired a Sierra Wireless 3G card (from eBay - very reasonable price) and have installed it in a Mikrotik RB411U.
It worked first time - took the same PPP parameters as the USB 3G card that had preceded it, all I needed to do was to change the interface over in winbox.
BUT - sometimes when the router starts up the 3G connection does not start up. It spends a long time 'authenticating' with the 3G network. It never fails but stays in the 'authenticating' state for so long that I have lost patience with it.
When this has happened even a full restart does not always kick the thing in to life.
Any experience with this effect - any suggestions? If there is a trick is there a script that I could put in to check functioning and kick the card/connection into life?
Any thoughts gratefully received.
The router is for mobile use so is restarted frequently.
