No connection to some devices

[#1]

So strange problem this morning.  My desktop and kindle will connect to internet as usual.  My two ipads, my own and work one and my son's laptop will not.  My ipad says the password is wrong.  I also can't connect via my desktop to the router address, just tries and tries.  What do I do?

Hi @BurntToast,

I'm sorry to hear that you are experiencing problems connecting to some of your devices. Are the affected devices all trying to connect via wireless or are any of them trying on a wired connection?

Please can you run through our troubleshooting guides here and let us know how you get on?
