iPhone 4 cannot connect to home Wi-Fi

I tried everything in all the posts above. What finally worked for me was to go to wifi settings click on the home wifi and then click on "forget network". Then turn off wifi. Then turn off the home modem for 2 mins. Turn on airplane mode and then turn it off.

[It might be a good idea (although i didn't need to) to turn the phone off while holding down the off button and home button at the same time, then turn the phone back on.]

Then turn on modem and reconnect phone to wifi.

If this doesn't work for you don't throw the phone away. Just keep trying all the suggestions in the posts above until something works. It's a matter of convincing the phone that the old settings are definitely gone and tricking it into believing you are connecting to a new network. Good luck.

I would try rebooting his phone near a network that you can turn off and on again.

My phone was fine while I went away. Then I came home and it wouldnt automatically recognise my home wifi. Never done it before.

Try everything.

This may sound stupid but I was having same issue with connecting to my wireless. When I went into the connection under dhcp the http proxy was set to off. Changed it to auto and it connected. Same with other iphone 4 we have....just saying

Just want to share on how did I solve my problem.

I have an iphone 4s and had never had any problem on connecting to wifi before. But when I moved to a new apartment, my iphone just cannot constantly stay connected with this perticular apartment wifi. I thought it was my iphone problem since other device can connect well in the apartment, but later I found out my iphone can connect very stably in a friend's apartment and at work place.

I did "forget the network", "reset network on iphone", "reset router", etc, but this problem still show up. I can connect, but will lost the connection in 2 min, then I will have to forget the network, re-enter password, and then lost connection in 2 min again.

There was once that I resetted my router and haven't put any password on, I found out that my iphone can stay connected!!! But of course it is not good to keep the wifi without password. Then I realize this might be a security authentication problem. I found out WAP and WAP2 doesn't work for my iphone, but WEP works!!! As long as I use a WEP password authentication on my router, my iphone can connect well!

I don't know why since my friend's apartment's router also use WAP which didn't cause trouble to my iphone, but it just doesn't work on my apartment router. I guess it related with other router setting which I don't quite know.

Good luck to everyone trying to solve this problem. Not be able to connect to wifi is quite bad...

I tried everything and most of the stuff was for like 5 minutes to get it working ex. The ice or the hair dryer , but I actually fixed mine all I did was went outside my house after turning the wifi off and my phone in air plane mode turned the wifi back on and it connected I guess it needs to be decently far away from the router and still connect, then I went the the wifi I was using clicked the blue right arrow went to DNs erased those numbers then typed 8.8.8.8 , then went to home screen , then went back scrolled down and pressed renew lease , went to home screen and clicked safari , then went inside , it disconnected then connected again and it's working perfectly fine now

This is probably too late to help you but it may help someone else. I suddenly started having a similar problem with my iphone. To make a long story short, using the Netgear Genie, I set up the "Guest" access on my modem with a password protection. It logged me right in with my iphone after entering the password. Hope this helps someone. 😀

I tried it and it worked. It is a miracle. This issue was bugging me since forever.

We are a family of four with a total of 16 devices (cell phones, ipad, pc, Wii, Dvd, Printers...) connecting to our Netgear wifi router. And some devices kepts being disconnected (never the pc...) without me understanding why.

Then, with this fix, 100% of these problems have been solved in the following 15 seconds...

Thank you thank you thank you!!!!

Problem Solved.... I upgraded my iPhone 4s and iPhone 4 to iOS7 and suddenly everything works perfectly again! A while back Apple brought out a patch that was only for iPhone 4s - after this patch the problem was solved. A little while later they brought out iOS 6.1.2 and the problem was back!

My point is.... Apple is very quick to cover up problems and tell people all kinds of stuff to try and hide their mistakes or make it look like a "feature"

My next phone will most definately not be an iPhone and Apple will not see me as a client ever again!

I found a solution! After trying changing all sorts of settings on both my iphone 4 and my home wifi router through Airport, i found the issue with connecting my iphone to the home wifi was solved simply by changing one setting through the Airport Utility. I changed my wireless home network radio channel (2.4GHz channel) to manual and selected channel 10.

This setting can be changed by:

Going into airport utility, select "edit" Airport Express,

select "Advanced",

select "Wi-Fi Settings",

select "Radio Channel",

turn off Automatic Channel on the 2.4GHz Channel,

and then selecting number "10" from the drop down menu.

So happy!! after hours of frustratingly trying different settings to see what worked, im relieved to have actually found a solution!

I dont usually sign up to post helpful things like this but thought id try and save any of you some long, dreadful hours messing about. Good luck!

Thanks for the great tip. It did not work by turning off my wireless printer but figured out that my IP cams were causing this problem. Swyched them off and my 4S is conneting like crazyyyy. Thanks again

I have also been having this issue and it did happen right after the upgrade. I have always been able to connect to my home and my work wifi. I now can only connect to my work wifi if I am sitting right next to it, from my desk I can no longer (even though it is an option to join, it won't allow). At home, I can no longer sit in my living room or be in my kitchen and connect, I have to be in the hallway near my computer room. My husband has an iPhone 4, I have the 4s...his works fine and has had NO problems. Me on the otherhand....I can't connect at any place that offers free wifi, yet he can. It makes me so mad...I called Apple to get help and of course they want me to pay and I am not doing that...I should not have this issue. I can guarentee that after my contract is up...I will NEVER have another Apple product as it ***** trying to find someone to help you. I have tried ALL that I can that each person on every website has suggested, except for restore and I truly don't want to have to that as I am worried I wouldn't back everything up correctly. I have come to a point of giving up...and just dealing with it...but it still makes me so mad.

I finally contacted apple on their website. They then set me up an appt at the apple store and when I went they tried connecting to wifi. The phone was shot and they gave me a brand new b/c I still had warranty.

I think I am having a similar issue with the new update. I just downloaded the latest update and can not connect to wi-fi at all. In my setting the wi-fi option is grayed out. Any fix-it would be awesome
