I'm currently having issues with my wifi freezing for all connected devices and any new devices that come into range at least once per day. Any hard wired devices back to the router continue to communicate fine. Only resolution is to reboot the router. I have an Arris cable modem/wireless router combo. I blocked the mac address for 2 apple watches that were obtaining IP addresses from the DHCP server and the freezing issue seems to have gone away. Is there something in the watch setup that should be changed? I'm not very familiar with how the watch communicates over wifi. I think the watch uses wifi info on the phone to communicate over wifi, but does it do that communication through the router or just between the phone and watch using a wifi signal? The DHCP server was assigning unique addresses to the watches and phones. Thank you for any insights you can offer.
