Hi,

I have a  network with a DECO X73 connecting to my internet (FTTC). I have 3 Deco X60s, 2 connect to the X73 using Ethernet. The last connects to the Mesh using WiFi.

When using the network I have had all sorts of issues getting devices to connect to the WiFi. I have narrowed it down a little, but for some devices (not all), I am unable to connect to the Guest WiFi. 

Devices that will connect are Windows 10 PCs, XBox

Devices that had never successfully connected for more than one session are devices such as TVs, (In particular a pair of JVC TVs that are approx 5 years old).

Today my Samsung S10 mobile stopped connecting to the Guest Network. (even though it has been fine for the rest of the week).

What is most frustrating is that connecting to the main WiFi seems to work every time for all the devices, but not the Guest Network.

I really need the Guest network as we often have guests stay and I don't want them to be able to access the part of the network the we use for Work.

Is there something I could try to make it more reliable?

(I've seen similar problem on this forum on an older router, but that was resolved by a firmware update... my systems are reporting that they are on the latest).

Cheers,

Stu.
