I set up a home network: Vodafone ISP Router to Netgear GS108PEv3 switch with OCN200 and two EAP245 V3 for my home network.  The switch also has a Humax digital freeview box connected (FVP5000T). I also used one of the RJ45 ports from an EAP245 to connect a Sony smart TV. The network was working fine for 18 months when it started showing problems with intermittent wifi drop out.  This was manageable until it started to affect my smart heating hub (Drayton Wiser Hub-R).

I was advised by Drayton to update the home network and ensure the EAP linked to the Hub-R was providing a dedicated SSID on 2.4GHz ideally on channel 1, 6 or 11.  I'm not a network engineer so didn't think twice about updating the software, and duly did so taking a back-up before I did.  Now my network controller (using the new online GUI) cannot see my switch or gateway. A quick check says that because the Netgear and Vodafone kit isn't compatible, but it shouldn't prevent it working, I just wont be able to control them (not an issue for me), however I have now lost the following functionality and cannot figure out why:

1.  Wired connection to TV no longer has internet service. If I try to connect the TV to the wifi, it connects to the SSID, but fails to get internet too.

2.  Wired connection to Humax FVP5000T no longer has internet.

3.  Wiser Hub-r works, but still drops out intermittently, despite a dedicated SSID on channel 11 using 2.4GHz and only being 4m away from EAP245.

4.  Amazon firestick HD is no longer able to connect to the internet, but can connect to the SSID LAN. 

5.  Any device using the wifi network can no longer use streaming sites such as Amazon Prime video or BBC iPlayer - for example Prime video connects but on trying to stream anything states "Internet Connection Error - your devices internet isn't working...", yet the device is connected and it will support Chrome, Safari, etc and let me connect to the OCN controller and Omada cloud.

6.  I can no longer access the vodafone router directly via IP address, or using the vodafone broadband app.

7.  When trying to connect some devices I have an error message saying they "Hotspot login cannot open the page because too many redirects occurred." I have no idea what that means.

When I run a ping test, I get a return from the router (0.69ms to 1.2ms), the OCN200 (0.56ms to 0.98ms) but I don't get anything when I ping the switch (should I?). If i try to access the router or switch directly via entering their IP into a web browser, it fails stating there is no internet connection.

I am still able to use my legacy SSIDs (but did try setting up a new one and no change) and they work for most things.  I also have a couple of Meross smart switches and they all work and can be accessed via the Meross cloud. So I definitely have an active net and internet, it's just got some unworkable glitches.

I can only assume that I have done something wrong, but cannot find any guidance on the settings required to use the new firmware supported Omada SDN. Can anyone offer any advice to correct this issue, or how to revert the EAP and OCN back to previous firmware that supported my network, albeit with some glitches.

Sorry for the long post, help would be appreciated.
