Hi @Elek,

The bug fix for Wi-Fi stability issue will be merged into the official firmware 4.33 which will be released in late December.

Thank you Emily, I will get back around Christmas, hopefully the new release will be under the tree.

Hello,

Same issue here too. Installed version 4.32 WK43 r86079. Will check. Awaiting the official release end of December.

Thank you.

After running the 4.32 WK43 r86079 version for a couple of days my iPhone got disconnected again. Reconnect says the password is incorrect. Waiting for 10-15 minutes solves the issue. So issue seems to be not fixed by this version.

Check on the new release.

Hi @alehzn,

The fix for the issue "It shows wrong password on the wireless client and unable to connect to WiFi successfully." is already merged to 4.32 WK43.

Can you check "Band Select" is enabled or disabled on the SSID profile?

Hi @Zyxel_Emily

I can't find that setting on my USG20W-VPN. Where can I find it. In the meantime I will install the new release posted by @jonatan

Hi @alehzn,

Please upgrade to the version posted by jonatan and check the Wi-Fi status.

If the issue still persists, please send your configuration file to me via private message.

Hi @Zyxel_Emily

Thank you for your reply. I have successfully upgraded to the version posted by @jonatan

Will keep an eye on the WiFi status and text you in case the issue still persists.

I am still running 4.25 as the last stable version after trying multiple "custom" FW releases in the past months, is this ever going to be fixed or should we just give up and change vendor?
