Description

Good day all,
i'm running OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530)
Kernel Version 3.10.49 over a TPlink wr842nd v2

Currently i use a 3G modem TPlink MA260 for wan connection.
I follow these document ( http://wiki.openwrt.org/doc/recipes/3gdongle ) to start to use the modem and it's works good but sometimes i see disconnections and reconnection.

This is what i found in the logread:

The wan connection return to UP in 10 seconds but it's really strange.
I think that itsn't a modem problem because i've 2 modem MA260 and this issue occur with both of them.

Any suggestions?

Thank you in advance
