I have similar issues. You can change it to only renew once every 21 days in the hh3 settings at 192.168.1.254
I've not seen this issue in a while now (probably because when it renews I'm not online) whereas when it was daily I saw it once or twice a week
My wireless didn't drop but I had to disconnect and reconnect to the wifi to make it work again.
