if you have little luck id almost track down the version 20 firmware and downgrade it and see if the fixes it??

I have had wifi play up on these devices.

When they work they are fine, when they play up they really play up and in every case replacing the router with another HG659 one fixes the issue.

Personally I dont like and no longer trust these devices, I replace them with Draytek's and once set up you never have to touch them.

Couple of ideas.. Give a different SSID for the 2.4G band than the 5G band - that way you know what you're connecting to. Agree with above to remove credentials from the devices that can't connect. And maybe the channel has changed and you've just got some interference where those devices are - you could try fixing the channel to something. Also stick with B026 - it fixes a wifi bug in B020.

 

RESOLVED!

And this was the issue.

Prior to the Factory reboot\restore, I only had 1 SSID, and as I weren't around when the Vodafone Tech installed it all, I'm guessing that the 5.0ghz was disabled.

The reboot\restore has reset this, and I've named both the 2.4 and 5.0 ghz SSID's the same, I'm guessing causing a conflict somewhere.

Naming the 2.4 and 5.0 ghz SSID's with a different suffix has resolved the issue and now all devices are back on the WLAN.

A couple of interesting things to note, I've got a Huawei P9 and the wife a Huawei P9 Lite. The P9 see's both the 2.4 and 5.0 SSID's and the P9 Lite only sees the 2.4 SSID.

The same goes too for the Xbox's...the One sees the 2.4 and 5.0 SSID's and the 360 only the 2.4 SSID.

Thanks to all for you help and suggestions. Cheers.
