My son's iPhone 5s connects to our home wifi a treat. I decided I wanted one, too, but opted for a used 4s. It is in very good condition and I don't think anything is wrong with it. When I activated it, it was still on IoS 6, so - at work and over the work's wifi to which it obviously connected - I upgraded to 8.1. I am now home and it will not connect to our wifi. I googled the problem and came across one solution - resetting network settings - and it did the trick, it seemed, for about a minute, but now it refuses to connect again. What's going one?

Is your wifi running over 5ghz? The 4s doesn't do 5ghz wifi.

Don't know, how do I find out? And what do I do if is is? And surely others have faced the same problem?

It's unlikely that your wifi would be in 5GHz only mode if it could do it. Also as a reset network settings sorted it out temporarily, It's clearly being picked up.

Just to clarify, can your 4S see the network in the wifi settings and what happens when you try to connect to it? Have you tried forgetting the network on the phone then reconnecting?

Yes, I can see the signal, an extender signal, an attached Fon and Fon's MyPlace. I can connect no bother. It's just that I don't connect to the Internet. Tried again a minute ago standing right next to the modem. I also tried forgetting the network, then rebooting.

Surely my wifi is also broadcasting over 2.4ghz? Can I not force the 4s to pick it up?

Just checked and my signal is being broadcast on 24.Ghz

Try rebooting the router. I have had issues that this solved in the past especially with BT's Homehub.

OK, I will. BTW tried the phone on Asda's free wifi and there were no problems.

Yes, that seems to have done the trick. Thanks.

Sounds like your router ran out of IP addresses, and a reboot cleared out the memory of machines used before.
