Hello
I am French, sorry for my english...
I come to the community, because I have a problem, it's 3 or 4 times that happens.
I have a TP-Link Archer C7 or AC1750 v.4 router and a Huawei 3372s dongle set in Stick mode.
I had the problem a few weeks ago and reinstall OpenWrt, so I went from the Snapshot version to the version 18.06.1, which normally is stable ...
Everything worked perfectly after that.
And now this problem is back: all the LEDs on the router indicate normal operation (LEDs on: Power, Wifi, Ethernet, Dongle Huawei fixed light in turquoise blue)
But no connection, both in Ethernet with my 2 computers, with my phone Wifi, no internet connection is possible, but I do not understand that there is no connection to the interface Openwrt, neither with FireFox, nor with Putty.
The 2nd and 3rd time it happened, I turned off the router with its On / Off button for more than 5 minutes and it came back, but not this time .....?
Did someone have the problem?
And what should I do, still reinstall everything ... I hope not.
Thank you in advance for the answers.
