Re: 3G Card Problem

Hi Brent,

Can you tell me if the router automatically connects to internet even if you dont do a ping test?

I have configures a 881G with PCEX-HSPA-G module and the Cellular interface never comes up untill I ping any internet IP from the router CLI.

Is there any configuration I need which will make the Cellular interface to come up as soon as the router is reloaded.

I have attached my current config.

Note : By cellular interface coming Up, I meant that Amber LED on the module will continously blinkin which indicates that the connection has not been established. Once I do a ping test from the router console, the LED becomes stable which shows that the connection is up and running,

Re: 3G Card Problem

I think that is the way that it works. when I was working thru the debugs, I would not see the cellular interface come up until the traffic started. In the same way if there was not interesting traffic after a period of time the interface would drop. I just though this was tied into the fact that it was associated with my LAN-to-LAN configuration and that is the way that operates.
