Looks like a nearby phone mast isn’t working as it should, sorry.

O2 says Looks like a nearby phone mast isn’t working as it should, sorry. I go check my nice 

Nighthawk M2 Mobile Router thats in IP passthrough...its offline! I reboot it it connects fine

Please Netgear fix this I should not need to manually reboot it every time a  mast goes down it should auto find the next mast.
