    Your laptop being able to pick up the network alone does not mean there isn't a problem with the wireless router or network.

    Do you connect your iPhone with any other wireless network besides your own and if so, any problem with any other network or just with your network?

    If your wireless network is no longer recognized at all by your iPhone to select and join or your iPhone doesn't connect with the network so you can view the network settings and select Forget This Network to erase the network settings and then try to rejoin the network, on your iPhone go to Settings > General > Reset and select Reset Network Settings. This will erase all wi-fi network settings from your iPhone for every wi-fi network you have connected your iPhone with. This will require rejoining every wi-fi network you have access to.

    Give this a try first.

    Allan, I have the same problem, have tried your reset, and it didn't work. What next?

    ie: happily using wifi at home until a couple of days ago. Today I got around to re-entering password, but no go. Other devices around the house are picking up wifi no problem.

    If no change after resetting network settings on your iPhone, the next step is restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup.

    If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup - you are unable to connect to any wi-fi network after doing so, your iPHone has a hardware problem with the wireless card or with something else.

    Yes to the first question (work) - and no, not connecting. Restored (and then restored data from back-up - was this the right thing to do? Although I don't like the idea of having to start everything from scratch!)

    Anyway, after the restore, still not connecting at work; will have to wait to test at home but I suspect I know the outcome... (call me a pessimist!)

    Per my previous post - restore with iTunes as a new iPhone or not from your iPhone's backup.

    Wi-Fi network settings saved on your iPhone are included with your iPhone's backup. If there is a problem with this data that is included with your iPhone's backup, restoring your iPhone with iTunes from your iPhone's backup will also restore the problem placing you right back where you started.

    Also per my previous post - +*if no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup - you are unable to connect to any wi-fi network after doing so, your iPHone has a hardware problem with the wireless card or with something else.*+
