Wifi issue with Epix (Gen 2)

Having owned the Epix (Gen 2) from new for a month, I have experienced issues where the watch is unable to both wifi sync and connect to my network (2.4GHz).

The only solution I have found so far is to power off/on the watch. Sync/Network connection resumes, but will revert to the above issue approx. 3-4 days in.

Is this a known issue? If so, is there an alternative resolution?

or

Could it be a hardware fault?

Watch is on software version 14.68 (after updating from 7.2x)

Thanks
