nr5101 Router Looses Cellular WAN

Getting very frustrated with my nr5101 router as the WAN connection seems to drop randomly but won't reconnect unless I reboot the router. It's been anywhere between 4 and 72 hours but it won't reconnect unless I do a reboot. Much faster speeds than my broadband but not a viable replacement if I have to reboot every few hours. Any suggestions?
