Hi there, 

I have been searching for an answer to this, and having factory reset the router, and updated the firmware, I have not been able to resolve it.

For some reason, I am unable to connect to the wifi unless I hold the router right next to my phone / other device. Once done the wifi works as expected, and I can move away from it. Although if I move out of range, I have to move right next to it to connect again. This is quite annoying when I have to keep the router in the window to get a decent 4G signal, and have multiple devices to connect. It seems to be fine if theres already one device connected, but if not, none of my devices can pick up the signal.

Is this some sort of power saving feature, or an issue with my router itself?

Thanks
