WiFi Not Connecting

Same problem for me. Connected no problem to our old wifi network when the watch was new. Changed the router and will not connect to the new one for love nor money. 

I've also got the problem. Except, I've been using the 645M on this wifi for more than a year, since I purchased it, with no issues. Then suddenly, recently, I get all the errors and issues described above. But nothing has changed about the network, which everything else in my house is using. Have also done all the reinstalls and resets and re-setups using watch/connect/express, to no avail. Took it to the Garmin Service Centre and they got it working on their wifi but still not on mine (or my office wifi which was a new one I tried). Cannot for the life of me see what's changed such that it no longer works.

i’ve been fiddling around just now (NOW 1/2nd/21) since my replacement 645m wont connect to our new router, replacement 645m never got a chance to connect the old one. what works for me is:

2.4ghz

WPA2

enc mode: TKIP

hope this works on yours

I'm not sure how helpful this will be to people but I contacted my ISP (Singtel, here in Singapore) in desperation, asking if there was some change in their network over the last few weeks that might have caused my problems.

They called me back and asked to do a remote upgrade of my router/wifi firmware. After they did this (apparently it took just a few minutes of downtime) I returned home and wifi connectivity/Spotify syncing was working again at last.

As I say, not sure hoe general that "solution" might be and of course I've no idea what would have been included in the firmware upgrade, but it seems clearly to have made a difference.

Cheers

Exact same problem here. Brand new device was working perfectly since Christmas. I changed my internet provider/router and now device won't recognise or find any network including a hotspot from my phone. I've tried all the various workarounds - via the Garmin apps, factory resets etc. To make things worse, when you attempt to add network, it attempts to connect, fails and then freezes on a Connection Failed screen. Only way to resolve it is hard reset - it's a joke. 

I've also emailed [email protected] directly as this seems to be a serious issue and deems many of the features useless. I was concerned it was related to my new internet provider but reading this thread, it's clear there's a wider bug somewhere. This really needs to be addressed Garmin. 

Have you find a solution?

Same problem here with my fenix 6X. No problem with the vivoactive 4 of my wife

Yes seem to have solved it.

I took the suggestion of resetting the wifi router from Garmin. Initially that didn't seem to help either. But it got me thinking and I contacted Singtel, who provides my home internet and asked them if there'd been any change in their system that might have caused the problems I was having. They called me back and asked if they could perform a remote upgrade of my router/wifi firmware. When I came home and tested again, Spotify synced over wifi again! It took quite a long time to find the network but it eventually did so and synced.

Hope that might be helpful to someone else.

same here... damn, this sis irritating
