Hello. I am having a problem with my iPhone 3G and 3GS. My problem is that I cannot connect to my WPA2 network with either phone. Both phones are version 3.1.2. If I remove my security key or reduce it to WEP, the phones see the network and connect immediately, once I've put in my password for the WEP. However, once I reestablish my WPA2 connection, both iPhones see the network but after I enter the network password, neither phone will connect. I get the "Unable to connect to
*** network" error. I am positive I am entering the password correctly.
We have tried replacing the 3G phone (did not solve the problem), and this network issue was actually one of the reasons I upgraded to the 3GS. Needless to say I was very disappointed to find that the problem exists on my 3GS as well.
I have called Apple but they are at a loss as to how to help me. One representative suggested I post my problem here and maybe the "very knowledgeable Apple community members" could help me (those were his exact words)...
Does your router allow you to use both WPA and WPA2 simultaneously? If so, try that as a work-around and use WPA on your iPhone and WPA2 on other devices. The difference between TKIP and AES encryption might make a difference.
I have a Linksys WRT160N wireless router. WPA & WPA2 are listed as two different, seperate security mode options. So, I think I would be unable to do as you suggested.
The WPA2 option lists the encryption type as TKIP
or AES, both in the same option box, so I'm not sure if/how the router differentiates between the two...
BTW, thank you for helping me. This is driving me nuts... 🙂
Pity, my Belkin N1 Vision router allows both at the same time. Just try switching the router to WPA to see if WPA2 is the issue (although it shouldn't be). The only other thing I can think of is to check your pass word/phrase carefully. Upper and lower case make a difference and can mistakes can easily be made on an iPhone keyboard.
You should use WPA2 with AES. On your phone, Settings>General>Reset>Reset Network Settings. Then, Settings>WiFi>Off. Once you've done that, reboot your router & make sure it is set to WPA2 with AES. Once your router is back up, go to settings on your phone & turn WiFi back on, see if you can connect now.
I tried this. No go. I know I'm doing it correctly because I'm seeing the change in my wireless connection on my PCs when I enable the MAC address and disable it.
I'm sorry to keep bugging you but thank you so much for working with me. I really, really appreciate this. 🙂
I don't know what type of router you have, but the way things work is that your network speed is slowed to the slowest device on the network unless you have a dual band router capable of broadcasting on two separate bands simultaneously, I.E.-G & N. I'm wondering out loud here, if perhaps if you set your router to broadcast at B & G, not N if that would solve your problem. Could be the N devices you have connect & thus, unless you have a dual band router, the g devices can't connect since the router is only broadcasting at N speed. Although the mixed setting should downgrade the whole system as slower devices connect.
