I have been having the same issue after the firware upgrade. I could get not get past 2 days without it hanging. I turned DNS Relay off a week ago and everything seemed to be working much better. Unfortunatally a couple power outages at home reset the router. But as of today I have reached 4.5 days on 1.11 with no slowdowns or hangs. I will keep my fingers crossed and will leave the relay off as a side effect my webpage lookups and browsing is much quicker then before.
