IPhone 3GS won't connect to home Wi-Fi?

A couple of hours ago my iPhone 3GS started to disconnect from my home Wi-Fi(my iPhone 3GS does have a 3G data plan if that makes any difference). And its still doing it. When I press on my Wi-Fi name it'll connect then 2 seconds later it'll disconnect and bring up a blank screen, and at the top it says login. Then a message will pop up saying there was hotspot login error because the server stopped responding. I've turned off my phone and turned it back on. I've unplugged my router and plugged it back in but it still won't connect. My ps3 and my android tablet is connected so why won't my phone connect?

The bands on wi-fi router makes a difference. If you have changed this then I would recommend you to restore the band on wi-fi router.

Try resetting the network on iPhone in Settings > General > Reset > Reset Network settings. Remember that by doing this reset, all your known wi-fi details (wi-fi networks that will connect automatically) will be lost. However you have to join those networks again and will be available automatically for next time use.

  • Why won't my iphone connect to my home Wi-Fi? I have an iphone 4 and whenever i try to connect it to my home Wi-Fi it says 'unable to join network'. On my parents' iphone the Wi-Fi works fine. I also have the same problem with my laptop. I can go to another Wi-Fi hotspot and it will work fine but with my laptop and my phone it never works. I've tried restarting my phone and the router already. How can i fix this?
  • Why won't my iPhone 4s connect to my home Wi-Fi? - 1 I didn't get the new ios update or whatever, but recently it hasn't been able to connect to my homes Wi-Fi. I've never had this problem before and my houses Wi-Fi doesn't have a password. It doesn't even seem to acknowledge that the Wi-Fi is there, and my iPad doesn't have this problem.
  • Why won't my brand new iPhone 5C won't connect to my home Wi-Fi? I just recently bought an iPhone 5C for my mom, along with an HTC One. The 4G LTE seems to work fine on both of them, but my iPhone can't seem to connect to my home internet (the HTC connected perfectly fine). I'm 100% sure I'm inputting the correct password, and it always comes up with the same error: "Unable to join the network '[my Wi-Fi name]'" I've tried turning the phone and router off and on, but it doesn't seem to be doing the trick…
