WiFi issues with Fenix 6 Pro and Unifi environment

Former Member over 4 years ago

Hi,

for weeks I'm trying to setup my fenix to connect to my wifi without any success. I think I almost tried every possible solution incl. a ticket with Garmin (they proposed to replace the watch but I think this won't help).

My network is containing the following equipment:

Unifi UDM Pro
Unifi 24 port PoE switch
2x Unifi AC Pro
PiHole but deactivated during testing.

I created multiple wifi networks, with and w/o password, only 2.4 Ghz networks, legacy support for old devices and whatsoever. Every time I try to sync over wifi or to update the Spotify playlists, the watch tries to connect to the wifi but ends up in the message "No internet connection". However, in the unifi dashboard I can see that the watch is connecting properly (IP address is assigned and even some data is exchanged).

If I set up a hotspot on my phone (iPhone) the watch can successfully connect as well as sync. That's why I think it's not a hardware issue and a replacement wouldn't make sense.
I'll try the same with the wifi at my parents house (only FritzBox) to ensure that it's not the watch.

Does anyone here has a similar setup/ issues and hopefully has a solution or hints how I can approach and probably fix it?

Many thanks in advance

Michael

I'm not familiar with Unifi but I did experience similar 'no internet connection' problems here last month:

On my router, WPA2 only did not work - I had to choose WPA + WPA2

I also disabled the WPS function.

I think also changing to the simplest form of your security on your Access Point also helps.

This is almost certainly not a hardware problem.

Thank you for your response.

I already tried using wifi networks without and even with very easy passwords. Other than that I can only chose between WPA2, WPA2-Enterprise, WPA2/WPA3, WPA3 or WPA3-Enterprise.

As far as I know WPA2(PSK) should work with the watch, correct?

I changed it to WPA1, WPA2 or even both. As far as I know WPS is not even supported with Unifi Devices.

I do not know what to test else. Only 2.4 vs. both, legacy support on and off (btw. the watch connects with g, not b). Maybe I should open the same or similar in the unifi board. I still don't understand that the watch connects successfully and retrieves an IP address, though.

Sorry to hear about your problems.

I have a Unifi environment myself at my home (UDMP, USW16poe and 4 APs (NanoHD + FlexHD).

I can sync my Fenix 6 Pro with no issues over wifi. I have nearly all funky shiny features (like auto-optimization, fast roaming, etc.) OFF to improve the stability of all the Apple devices in my network as well as the SONOS speakers.

Maybe you have to check whether these so called "enhancements" (that often bring more problems than really helping) are on or off.

Works for me too with my UniFi setup. No issues at all. No fancy features like fast roaming. Just a ”vanilla” setup.

Fenix -> UAP-AC-Lite/U6-Lite -> US-8-60W -> USG-3P -> ISP.

Hi Björn,

vielen Dank für deine Antwort.

I finally found the issue. It's the firewall settings to drop all connections on port 53 (outbound) in order to force all devices to use PiHole as the DNS.

I changed the rules to LAN in to redirect to PiHole and now everything works.

Thank you everyone!

This was exactly my issue as well. And a good solution using NAT to direct this otherwise blocked DNS traffic to a local DNS server. I bet there are a few other devices on my network that will now be showing less obscure error messages.
