Description

Sorry for that title, I don't know what I should be writing here.

I am using this version of OpenWrt:

http://ofmodemsandmen.com/downloads.html

In particular this one:

http://ofmodemsandmen.com/download/Huntsman/openwrt-wr1043nd-v1-HM2013-06-18.bin

For my TP-Link WR1043ND. Modem is a Huawei E372.
This version uses kernel:

Linux openwrt-router 3.8.13 #11 Mon Jun 17 19:03:36 PDT 2013 mips GNU/Linux

Now the problem:

The modem disconnects (by what I am not sure, it is not the 24h disconnect of my ISP) and dmesg and logread output these errors:

dmesg:

Now you might say, "don't bother us with other versions, ask the developers themselves" but they said it is not their problem and they don't know/can fix it.
I attached a screenshot, because I can't get a link of the comment I made there.
