iPhone not connecting to Network

[EvianBaby]

Our internet went down in the office over the weekend so I rebooted everything and it started working fine again yesterday morning, however my iphone won't connect to it now.

I tried to select the network manually and it asked for the password which I entered but it just said it couldn't connect.

I then rebooted everything again, the router, the server and my iphone.

It still wouldn't connect automatically (as it always has done) so tried to select it again and now it doesn't even ask for the password, just says it can't connect.

Anyone got any ideas what I can try now?

Do you have MAC address filtering enabled? Could it be that your iPhone's entry is missing somehow?

[EvianBaby]

I should add all the laptops are picking up the network as are two other iphones that get used. One is a 4, the other a 4S.

Mine is a 3GS.

How do I go about finding that out Mark?

[MarkRae]

Apologies - when you said you "rebooted everything" I assumed you were responsible for the network. I'd suggest you have a word with the network admin...

[EvianBaby]

No, sorry. My knowledge on these things is extremely basic. As much as turn it on and off again pretty much.

Sadly our support company is an external company who do everything remotely and do not (for some reason) know a single thing about Apple products - or just refuse to acknowledge them.

Can you confirm that your iPhone can connect to other wireless networks, and that you haven't accidentally switched its wireless connectivity off...?

[EvianBaby]

Yeah, it still works no problems with my home network. Connects automatically as soon as it's in range.

[MarkRae]

OK, so it's not the iPhone itself which would indicate that the issue lies with the network. Difficult to say without more information, though...

[EvianBaby]

What sort of information would be helpful?
