Router model: TP-Link TL-MR3220 v2
Firmware version: MultiWeb_318_2015-03-14 ( OpenWRT r44510 ) / LuCI
(git-15.051.48491-4137afe) (ROOTer MultiWeb 3.18 2015-03-14 Lite) from
[http://ofmodemsandmen.com/downloadsm.html]
OpenWRT Kernel Version: 3.18.7
USB modem 1: Huawei E3272s-153 (HW: CH1E3272SM Ver.B, FW: 21.470.09.00.00)
USB modem 2: Huawei E3272s-210 (HW: CH2E3272SM, FW: 21.470.05.00.00)
Both modems are configured as serial/PPP. Only a single modem is used at a
time.
With any of such modems, router works fine for weeks. But in case of
massive downloads (about 1GB/hour), it often "loses" the modem,
continuously reporting the same error:

The problem occur with both modems having different hardware/firmware
versions.
This state could be 100% fixed by modem removal and reinsertion.
