I am on an Ultrahub, with a modem to FibreX.
When I am uploading large files, like 29GB, my connection just dies after a variable amount of time.
I can reproduce it everytime.
The same thing happens with two other routers, one an older Vodafone supplied one, one my Edgerouter.
The connection will come back after 10-15 mins if I just leave it.
If I powercycle the modem, (not the router) then the connection comes back when it's done starting up.
This implies that ths the modem, or something else upstream.
Vodafone are sending a technician.
But I wanted to know if the modem has a newer version. THe one I have is a fair few years old.
