A 3G Mini pci-e modem problem in RB411U@5.15
I use a Huawei EM660 modem (mini pci-e slot) with RB411U to build a 3G router. Usually, the ppp-out will disconnect after hours or days running, so I hope the watchdog can help me correct the problem. But the ppp-out can not build a 3G connection after reboot unless I turn off an turn on the power.
This problem does not happen in a 3g USB modem (Huawei EC 122). The change log of 4.13 announce “added USB power reset feature”. It can give the usb port a real reset.
Can MT development give the mini pci-e power reset feature? All my 3G routers are in remote sensors, so power reset feature is very important to me.
