GT90H won't search for networks

[Donniet81]

Hi all, really hoping someone can help me with my boys tablet!
On the second one and having the same problem with the wifi. When we've first switched it on we could get a list on networks. It'll work for about an hour then it looses all connections. When you go into settings it says the wifi's off, but when you try to switch it on it doesn't highlight blue and still says you need to switch wifi on for it to work. Really hoping one of you lovely lot can help us

Welcome to the forum

I have a couple suggestions. They will rule out some other possible issues. restart the tablet and restart the WiFi router. If neither of those help try somewhere else at a public hotspot. If it still doesn't get WiFi working you may want to consider a factory reset.
