Issues with the IPhone SE (2020) and WIFI

Any one else having issues with the IPhone SE (2020) and WIFI still ?

Long Story short : Gfast having stability issues - lots of investigation later stand alone modem + new router. Also been having issue with the IPhone SE wifi for ages (despite another SE (2016) perfectly fine)

Ran the new setup for about a month. Much better logging on the new router allowed me to see exactly what was happening before a disconnect of the modem. The same couple of mac addresses were always reauthenticating with the router just before. Doing some reading and extrapolating, I made a guess and checked out the interfaces on the IPhone SE both the MACs that caused the fails were from the 2.4G interface of the SE(2020). So turned off the 2.4G interface on the the SE (ie. forgot the network and only remembered the 5G one).

The wifi connectivity on the IPhone SE has remarkedly improved, and the hang ups have stopped. Only has been a few days and have had a few gfast stable days before but feel that I have identified the issue and that it is not just a shot in the dark fix this time.

Found out that a particular brand of routers (which use 802.11ax) has issues with some intel implementations of 2.4G wifi interfaces. This lead to me looking at all the 2.4G interface devices in the home.

Basically if you are having issues with wifi and or network stability and you own a IPhone SE (2020), with a multi band router. Make sure the router is using a separate SID for 2.4 & 5G and then have the wifi on the IPhone have just the 5G SID configured. I have other devices connected to the 2.4 G at the same time and no issues so far. Also have bluetooth running on the IPhone SE at the same time (which I know has caused some people problems) seems all fine as long as 2.4G not configured for the home network.

Sorry I should have said, there is no question here. I just wanted to share what I had found helpful and there was no other way for me to post this as 'Tips' not available if you are a first time poster/long time lurker. I have come across so many different posts from lots of different message boards, lots of different people but never any real answers - in trying to solve my issue. In most cases the following things are common gfast, IPhone use, IT skilled users and all have these disconnects from the WAN side.

Have been having issues with Gfast and EE since Sept 2021. Lots of hang ups from the EE side. Had all the usual investigations, new smart router etc. The smart routers logging is not useless but only just. However from the provisioning of the gfast to sept 2021 everything was fine (about 6 months) then suddenly it was terrible (Sept 2021). Has taken till now to get somewhere with it. On removing the 2.4 WIFI connections from the IPhone SE(2020), it has gone from multiple disconnects a day (at the worst was 100 in a 3 hour period) to 1 disconnect during the night every 4 days. And also the WIFI connectivity for the IPhone SE (2020) improved dramatically. Husband has been moaning about the WIFI in our home for at least a year. I have an older IPhone no problems with the WIFI in the same rooms he has issues in. He has the WIFI turned on, on his phone, not a moan to be heard (in regards to WIFI anyway, I'm not a miracle worker :-) ) since the 2.4G network was forgotten.

When I am talking about disconnects here I am referring to disconnects from the WAN side of the system so there would be no internet connection for any device attached to the router. Not the wifi disconnects on the phone.
