My wife and daughter have two iPhones and yesterday, they both started having issues with their wifi. The other devices in the house work normally. The router is an TP-link archer AC 1200.
The funny thing is, that when I've tried just about everything else I can thi k of, except for a factory reset of the phones. I think of the guest network function on the router. So I made a new network, and thir access to the internet works fine. But they can't use chrlmecasts etc in the house, because I don't want to grant an unsecured network local access, so everyone can connect to it.
The phones connect to the router, at least it says so on their phones. But when I check on the router client list, their phones doesn't come up. - Note that this is only an issue with the encrypted network, not the guest network.
Anyone know a workaround, except a factory reset? - I've Google quite a bit around about resetting network settings, forgetting the network, reconnect, reboot the router, update the router firmware etc. But still the same issue.
