My IPhone 4 will not link to my home Wifi network.  The IPad will but the IPhone gives the message "Unable to join the network".  I does not even ask for the password.  Any suggestions?


iPhone 4, iOS 5.1

    Will it join other wifi networks?  Did it connect to your wifi before but has now stopped?

    The IPhone has connected with other wireless networks but not this one - I installed a new CISCO router - oddly another IPhone 4S in the house does connect to the same router without any problem (as does the IPad)

    On your phone go to Settings>General>Reset>Reset Network Settings (note: this will remove passwords for previously joined networks so you will have to re-enter them).  Also confirm that Ask to Join Networks is set to On in Settings>Wi-Fi.  If this doesn't work try power-cycling the wireless router (unplug for 30 seconds, plug back in).  (Sometimes the DHCP service will hang and not try to assign an IP to a new device while other devices successfully connect because they already have an IP address assigned.)

    Thanks for the advice - I confirmed all the settings and then power-cycled the router.

     

    This time when I selected my home network it prompted me for the password - but when I entered it I received the same error message. "Unable to join network".

     

    I have entered the password three times - checking carefully each time - I am sure it is the correct password - but still wont' connect.

    Since you say another 4S can connect to your router, that would seem to rule out incompatibility in the router's settings or firmware.  Are you certain you are entering the password correctly (they are, of course, case sensitive).

    Yeah - I checked that 3 times before I posted ... seemed too obvious and I didn't want to be embarassed - not a password issue.  The 4S and IPad connect but the 4 doesn't - could it be a WPA WPA2 issue?

    Actually WPA/WPA2 (AES) is the preferred security protocol.  Check to see if there is a firmware update for your router (even if it's new).  Also, here's a longer list of recommended settings from Apple that you might want to check your router against: http://support.apple.com/kb/HT4199.  Finally, here's a longer list of troubleshooting steps you might want to go through: http://support.apple.com/kb/TS1398.

    Great. perfect. worked exactly as described.  NOW.....whay can't the iPhone instead of saying "Unable to join network" - come up with a dialogue box SUGGESTING :  "you may want to check Settings>General>Reset>Reset Network Settings" and make sure your "Ask to Join Networks is set to On in Settings>Wi-Fi".  that would be more helpful than"unable to join netowrk" - which we know already - DUH.

    If you don't want to forget all the passwords to your other networks by doing "Reset Network Settings", you can try just clicking on the <right arrow> for the network you're unable to sign into; then select "Forget this Network", then try logging into it again with "Ask to Join Networks" on.

     

    This works if you've logged into a specific network in the past and cannot any more because it removes all your old settings for that network (e.g. an obsolete password) and gives you the opportunity to type them in again.
