Any Windows 10 gurus? Wireless Internet issues....

[crays]

The first (replacement) S8 I got had this issue. It was a FU phone.

1st S8 - black screen within 30 days.
2nd S8 - no internet (some wifi security bug in the hardware) would connect to the WiFi but could not get to the internet.
3rd S8 - 2 years now, so far so good.

Fortunately, the first 2 were so new that they replaced without too much trouble and for no charge (as one would expect).

Mine is about 1.5 yrs old. Guess I'll tough it out for a while longer. Intermittently does what your 2nd one did, but only at home that I have noticed. Perhaps that's because the other 2 networks I use with any frequency are both 2.4G and home is 5G.

And thanks for the quick input.
