Sorry - can't help, but I've got exactly the same problem... I've got 2 Samsung S5 Mini's. The I had Andorid Wear on one, but not the other and last week I noticed the WIFI was off. I flattened the phone and factory reset it... all the apps went back on and WIFI worked... added Wear last and WIFI stopped. Uninstalled and WIFI worked fine again. Installed Wear on the second phone and all appeared well for about 24 hours and then it stopped... Still not 100% where the bug sits. Is it worth posting comments in the Wear review section? Do you reckon anyone from Google ever reads them...? Makes the watch unusable.
