Sorry bumping up this old thread.
As far as I being informed, we can't have internet access by connecting PC to the BTU Huawei (optical modem) ethernet ports unless we connect to the wifi router LAN.
I have similar situation where I need to shift my wifi router to upstairs through a long LAN cable that connected to BTU Huawei.
This is because I want to cover the upstairs wifi signal temporary. In fact, I can have balance wifi signal for both upstair and downstairs after I shift wifi router to upstairs.
I know you would suggest wifi extender / powerline but I need some time since we are having MCO now...
I wish I can connect my downstairs desktop directly to BTU Huawei through LAN cable.
So, this method above would work, while maintaining the same working condition for upstairs wifi router?
I'm not sure what is your condition. This method only works for one PC only when you don't have router. You are now asking for connect downstairs desktop PC directly to BTU, yes it may works. However, nope for the wifi router for upstairs. I guess your current situation is BTU to wifi router, this is the only best situation, so please avoid BTU to desktop PC method.
You still need to pull a long LAN cable to upstairs and
buy a new wifi router (not shift your current router to upstairs) to put at upstairs. So you can connect the upstairs wifi router to your downstairs main router to get access to the internet on wifi.
