Slow to connect to home base

Just curious if there is a fix to a very slow connection time to the home base for viewing live camera feed.
System is one month old and is the HD system.
Six cameras and one doorbell. All cameras have solar panels.
Wifi in home is 100mbps and full signal to all devices.
Live feed login takes over ten seconds or error comes back cannot connect to home base. Have read through all the threads and tried all suggestions.
The connection is good after reinstalling the app but only lasts an hour tops.
Also face recognition does not work. Have put pictures into the app and the cameras still go off.

Any suggestions would be greatly appreciated as I have contacted eufy support 3 times and they have not got back to me.

So far my opinion of eufy is not a good one
