• Answer:

  Unplug the wireless routers power for about 30 seconds and plug it back in. Watch the lights go through the blinky turny on thingy (sorry to get so technical lol). Once it's all done booting up it should be fine. IF THAT DOESN'T WORK On your iPHone go to Settings > General > Reset and then pick only the one that says Reset Network Settings and confirm you want to reset. The phone will reboot and when it comes back up you should be able to join the wireless network with no problems. This one is second because you will lose any login info for any wireless network you've already joined. So if you are on one at school, work, friends houses or something like that you'll have to redo them all.
