I'm trying to use a Vodafone K5160 with my Vigor 2860ac to get a 4g WAN. When plugged in to a USB port, the connection is made and the 4g service lasts generally no more than 5 minutes before the dongle reboots, and sometimes the Vigor itself reboots.
In normal usage without the dongle plugged in the router has behaved fine for months. When the dongle is plugged directly in to my computer, it too seems absolutely fine, no rebooting.
I can't figure out what the problem is - please help!
Many thanks
Richard
