wi-fi error 0300

Hi everyone,

I'm stuck with the error in subject.

SSID and password are correct infact watch pass the connection test.

But when I try to do a wi-fi sychronization it remains in wi-fi search till the error appears.

When in search for a network if I go back to previous screen, display show "syncing..." but doesn't complete any sychronization.

Any suggestions?

Thanks

Fenix 8 - 47"

software 15.32

wi-fi 28.85

    Hello

    I am sorry to hear you are having this issue. First I would recommend walking through these WiFi troubleshooting steps: Setting Up and Troubleshooting Wi-Fi on a Garmin Outdoor Watch

    If you are still having this issue, I would recommend reaching out to Garmin Product Support.

    Hi, thanks for reply. I've done all the steps in the WiFi troubleshooting guide but the error remains. The strange thing Is that all connection tests were successful, but every synchronization fails. Before last firmware update, synchronization works like a charm.

    Maybe Is there a bug in 15.32 firmware?

    “I’m having the same issue, but instead of error 0300, I just get a message saying ‘Can’t connect to Wi-Fi’. Restarting the Fenix 8 usually fixes it, but once it disconnects again, it won’t reconnect.”

    Hi, Roby. You're right: restarting the watch fixes it, but only once. When it disconnects again some times connects but didn't sync, some times didn't connect at all, a few times reconnects and sync. Nothing changes powering off and restarting again. Modifing modem to transmit only in 2.4Ghz (before 2.4Ghz & 5Ghz band steering) was useless. I'm dazed and confused...

    This is probably due to disabling 8.2.11.b/g, on your router (SSID settings).

    Sometimes this is a minimum-data-rate control on a SSID, such that if you set to say 12Mbps, you exclude b (but not g).  If you dig around your routers' settings, try to find (or use forum/internet search) how to disable/enable 802.11.b (and/or g).

    Hi to all,

    I've made other changes in router: after I've disabled 5GHz channel (now only 2.4GHz is active), I've forced 802.11b/g/n protocol (instead of 802.11g/n/ax).

    After some days of tests I got the error only a couple of times, but 90% of attemps works.

    So I can say It seems to work...

    Don't know if this was the problem, I've made no changes in router configuration from years and synchronization worked fine from the beginning (watch purchased about 6 months ago) with 2.4GHz/5GHz active at the same time in band steering and 802.11g/n/ax.

    I would like to thank everyone for the replies. Much appreciated.

    Ciao.

    If you want to get to the bottom of this 10% of failures, I'd take a look at the router logs for the exact window when you're trying to connect/sync.  There might be some association failures or perhaps a DHCP lease failure or WPA issue, it's tough to guess.  

    I run Unifi stuff and do SMTP logging (plus I can SSH into the full kernel/daemon logs), so I get a ridiculous amount of logging to peruse, as needed, but I'm a (mostly former) OS s/w engineer, so I tend to log/keep as much data as I can get at (and I enjoy perusing stack-failures and such, which is perhaps a bit on the unusual side... Grinning).
