Phone Disconnects From Home Wifi And Won't Reconnect.

[Gizmonster]

My phone is a Sony Xperia 10 III trying to connect to my Virgin Media router.
So initially my phone will connect to my home router with no problems.
I go out for a while and when I come back home later, it won't reconnect.
I click “network and internet” . The WiFi switch is toggled “on” and it says “not connected”. I click on “WiFi” and it says “searching for networks”. The circle just keeps going round and round and no networks show up, even though I know that usually it’ll pick up about 4 networks. Now I know that if I reboot my phone, the issue will be resolved, but I shouldn’t have to keep rebooting my phone every time I want to reconnect to my home WiFi.

When I go into “WiFi” and scroll down to the bottom, I then click on “WiFi data usage”. In there is a graph and it says I’ve used 5.93 GB, but the graph rises up to 100% and levels off - it looks as though my limit for WiFi usage is 5 GB and it might be not letting me access WiFi as I’ve reached my limit.
Ideally I’d like to remove this WiFi limit, but I can’t seem to find where ….. but what I have done is gone into my WiFi network by selecting it from the list, then I click on “advanced” and then I click on “network usage” and change it from “detect automatically”" to “treat as unmetered”. I was hoping this might fix things but it's still the same.

Anyone any ideas please??

Data usage could be 5 gb but there’s no limit on wifi usage.Not sure why your phone should be disconnecting from your home phone tho.

Looking at it again, I don't think my WiFi has a cap. I wrongly assumed that I'd reached my limit, because the graph plateaus out.
I'm guessing that this plateau is when the problem first started and no WiFi has been used since - hence the plateau.
But the problem persists, which is fixed when I reboot my phone .... but if I go out and come back I'm back to square one and can't connect to my home router .... unless I reboot my phone again ....

Have you tried bouncing the whole network, i.e. unplugging the router (and any switches an hubs) from the wall for five minutes?

[Gizmonster]

Yea I've reset the router .... to no avail.
It's weird because it acts like it's looking for networks, but the circle just keeps spinning and it finds nothing, although I've just looked and there are another 7 networks nearby.

I'm not sure that anything here will help but I'll post the link anyway, just in case there's something useful there:

Until you've found a solution though, a quicker workaround (compared to rebooting your phone) is likely to be turning on Airplane Mode, waiting just a moment or two and then turning it back on again. That's solved wi-fi connection problems for me (even if only temporarily) many times on Android phones.
