    If it's not one thing it's another....

    This is not an uncommon issue, but I have not found a solution despite trying everything I've read.

    I have two computers, an iPad, and an Apple TV that have not trouble connecting to my home network. WPA 2 Personal via linksys b/g/n router. No issues anywhere in the house. But now my iPhone 4 refuses to join the network. I get the "Unable to join the network xxxx" message.

    I've tried
    Airplane mode + wifi on
    Resetting the router
    Switching to WEP and then back to WPA 2
    Forgetting the network and re-entering the password
    Restoring the phone
    Etc...

    Basically the phone just won't join. Period. I have noticed one tell-tale little detail: When you enter the password to a network the "join" button does not light up until you enter the correct number of characters. When I am entering what I absolutely know to be the correct password, the "join" button lights up two characters too early.

    WHAT THE FRAK IS GOING ON HERE?

    This is the correct network....the correct password....the correct settings.....everything is right. But the phone refuses to connect.

    Anyone have another idea?

    Nothin'?

    Man, this is driving me nuts.

    I've been 1-2ed by iOS 5:

    1) iCloud data backup had a setting that allowed tons of data to be transferred via 3G when wifi wasn't available. I didn't know I had to opt out of that.

    2) iOS has some kind of glitch that is not letting me connect to wifi at all.

    Result:

    No wifi connection and a maxed out data limit for the month with 9 days left.

    Bollocks. Total bollocks.

    Try a reset of your network settings and then re-entering your data.

    Thanks for the input, but, as I said in my first post, I've tried that. Multiple times. No joy.

    Actually, you never mentioned that. Sorry. Try a DFU restore as new and see if that helps.

    My Verizon iPhone has been having troubles with my wifi (original time capsule). In fact, last time I was at my parents i realized i had wifi off because of the issue. Then it wouldn't connect to theirs, and when it did (showing on the airport utility), my phone was till showing 3G, I had to shut the phone down to get it to show.

    Yesterday it wouldn't connect to the TC at all, nor see the network. I had to manually enter it and it decided to finally connect.

    I'm pretty sure i have a hardware problem - it's crossed the iOS update, but I want to play with it some more and see if I can narrow it down some.

    If you have done all the normal steps, I'd be apt to think it was the phones wifi radio. Good luck sorting it out, I feel your pain (but not the data running out part :))

    Thanks. I had your issue back on iOs 4.3. I forget which fix corrected it though. Took a day or two.

    I'd be inclined to think it was the wifi radio too, but I can connect to other wifi networks. Just not my own home network.

    Just for kicks have you tried turning off your password for your network and seeing if it will connect?

    That is so stupidly simple, it might just work.

    I'll give it a shot when I get home.

    Yeah. That did it. How insane is that? You can add this to the one thousand and one ridiculous fixes for iPhone wifi connectivity problems that are out there:

    Disable your wifi password
    Connect your phone the network
    Reestablish your password
    Reconnect your phone to the network by entering the password

    Somehow that resets something somewhere.

    Check the router's MAC filtering

    Something to try is to disable security on the router. If the iPhone still cannot join the network, check to see if you have MAC filtering enabled on the router. You may have to manually add the iPhone's WiFi MAC address to the "allowed" MAC addresses on the router. To find the iPhone MAC address, go to Settings -> General -> About and look at the WiFi Address

    Change from WPA2 to WPA

    I had this same issue today. However, updating this worked for me.

    This happened to me to the point that I went out and purchased a new router...issue was resolved.

    A lot of older routers can't handle a bunch of connected devices; in my home I have 2 ATVs, 3 iPhones, 2 iPads, 2 MBP's, an iMac, a Sonos System, and a PS3 all connected to my home network. A lot of home network can't handle connecting all these different devices.

    That may be your issue - hope that helps!

    Try this if you see your usual network but are unable to connect

    Hi, if you can see the wi fi network but are unable to connect, you can try the following -

    1. Choose the wi fi network manually - blue arrow towards right
    2. You will come across the DHCP menu which says 'forget this network', at the top... go towards the bottom of this page
    3. You will see - 'renew lease', press this one

    You are likely to connect now. All best!

    I had the same problem. Removing security also worked for me. Until I left the house and now I am in a situation where I have to remove and reset security every time I return home in order to access wifi. Can anyone please help???

    Answer to the problem

    Just disabled the password on the router - iPhone 4 joined the network.
    Then enabled the password again and the iPhone 4 recognized the network and accepted the password - back on wi-fi!

    WPA2 vs WEP

    I had all the same issues and have gone through all previous suggestions. Finally looking into my router security settings I noticed my router was set to WPA2 and not WEP. When I logged in the "other" then set the security to "WPA2" then entered my pass I was good to go....maybe this will solve the issue for someone else. Good luck. If I get kicked off agin I will report back.
