iPhone 4 cannot connect to home Wi-Fi

Lucky you! Am so annoyed!

I've reset and restarted the router several times. This issue seems to only affect the iPhone 4S in my case. All other devices connect properly and consistently.

this worked for me! typed in my wireless key from back of hub and hey presto 🙂

thanks x

Greg,

I was having the same problem and took your advice about "forgetting the network". It worked! Thank you so much!!!!!

GregTB,

I had the same problem that iRageU95 had. I followed your succinct detailed instructions, and they worked perfectly. Thanks so much for sharing your knowledge and expertise!

Sincerely,

RJ

Thanks for your detailed explanation for the solution. My devices (ipad and iphone 4) are now working.

Hooray! Your steps worked perfectly for me too, and I appreciated your "guess" as to why it worked. Thanks so much for posting!

Thanks for the tip on forget this network and reconnecting again. It fixed my wifi. And ignore the ungrateful douchebags in here. I have my WiFi again.

Brian E the first is right!!!!!! I just got an iPhone 4s and it would see my home network but never connect I enablement WMM and it worked. I am connected.

"forget this Network" then try again

Thanks Greg, This was what I was missing.

Do you know where this information would be on the Airport Extreme?

Thanks to both of you. I set a channel rather than 'automatic' and it's all working fine now - a HUGE THANKS! :)

Hello guys,

Similar problem for me, since iPhone couldn't join my home Mode N wireless in my case during last 3 days.

Looks like i have come to some solution/conclusions after burning my brain.

My set-up:

Modem: Linksys WAG120-n (Only Bridge - DHCP Off)

Router: Apple Extreme - N mode @ 5GHz (Create Wireless Network + Router Mode: DHCP Only)

Peripherals: Apple Express (Join Wireless) + Time Capsule (Join Wireless)

iPhone 4: 5.0.1 (9A405), Modem Firmware: 04.11.08

During more than last year everything was working perfectly and my iPhone 4 (5.0.1) was joinning my wireless.

Suddenly some days ago, iPhone couldn't even locate my wireless at all.

* Keep in mind the mass Airport firmware update released some days ago. I did this update and i am afraid issues started after that moment.

I have started trying everything.

- When Extreme was set to n (b/g compatible mode), iPhone could locate & join my wireless.

- When Extreme was set to n, iPhone couldn't even locate it.

- When i shutted Extreme down, and enabled Linksys Wireless (n mode) with DHCP. iPhone could locate it & join it !!!

I will skip describing all iPhone steps i've done several times:

- Forget this network, - Turn WiFi Off, - Airplane mode on/off, - Shut down, - Static IP, - Renew Lease, etc etc

Finally and accidentally i discovered the following:

Apple Extreme -> Available Wireless Security :

i) for Radio Mode n only (5GHz or 2.4 GHz)

- WPA2 Personal

- WPA2 Enterprise

ii) for Radio Mode n (b/g compatible)

- WEP

- WPA/WPA2 Personal

- WPA2 Personal

- WPA/WPA2 Enterprise

- WPA2 Enterprise

iPhone

Available Wireless Security (delivered when select "Other Netwrok -> Security")

- WEP

- WPA

- WPA2

- WPA Enterprise

- WPA2 Enterprise

1) For Mode n only, my Extreme offers only WPA2 Personal, something that iPhone doesn't accept.

(As for - WPA2 Enterprise) i totally skip it, never used it, never understood all those settings.

Hard to say wether those was always iPhone's defaults or Extreme's poor Security options came after recent update.

But this is the reason my iPhone lost my home's wireless. Proof is that (after discovering this) my iPhone can join my N wireless if no Security is used, and this is why my iPhone could join Linksy's N mode (Linksys delivers all Security options that iPhone accepts, WPA2 mixed included)

My workaround of course reffers to Extreme users, but the lack of WPA2 Personal in iPhone, or the combination of Security you are using between your (any) Router & your iPhone may be the answer to some cases.

Good luck

Dont know why but I would try turning off all your other WIFI devices then trying the new iPhone. Might give clue as to where the problem is

Me too - can't yet on home internet wi-fi and as I live in a black spot - currently have no internet access on my iphone - 2 laptops in the house working fine!!!!!
