Apple iPhone 4S WiFi problems > fixed

I am having the same problem when not connected to a WIFI network, i.e. using 3G. Is anyone else having the same issue and if so have you been able to get a resolution? Apple changed the phone 3 times then suggested it was the simcard, so i changed this and still the issue persists. REALLY THINKING ABOUT GOING TO A WINDOWS PHONE!!!!!!!!!!!!!!!!!!!!!!!!!!

Apples support article http://support.apple.com/kb/HT4199 Even states that its reccomended for WPA2 Wireless security setting.

Which makes sense, and is a good thing for 2 reasons

1. WEP is a older type of security its not as secure as WPA2, WEP can be cracked as low as 5 minutes.

2. WPA2 Is more compatible with mobile devices.

So keeps your information more secure, and your net work is more compatible, whats wrong with that?

Thank you so much!🙂

I am having the same problem since updating my phone ( iPhone 4s ). Everything was fine before the update and now as soon as the phone sleeps it drops the network. I have tried restoring the phone, forgeting the network and re-adding it. Nothing works. It just will not stay connected now. I connect to serveral different wifi networks and the resaults are the same so it is not tied to my home router but all kinds of wifi hardware.

Maybe I should roll back the OS... I have not tried that yet

Sorry to ask such a dumb question, but you said you "accessed my wifi router settings (Linksys wrt54g)> udpated wireless security settings from WEP to WPA2."

How do you do this? On your computer? On the router? Through your internet company on the phone?

Thanks for any help for someone who's not tech savvy. I don't even know what router I have, or which is the router and which is the modem (there are two boxes).

I am on a new-ish iMac.

Many thanks for your reply.

Yes, it worked!

I really appreciate that you took the time to help me.

Ok, never had a problem with the wifi...until today.

I had set up a new wireless network for my dad. Signal to the iphone 4 was weak (whereas my dads pc was strong) So I chalked it up to being my iphone. Read that I needed to reset the network settings. So which I did. Signal was still weak so I figured it was just the router. Fast forward to my place. I come home and re-connect to my home wireless settings. It wouldn't. It kept telling me that it was unable to connect to the network....even though I am sitting in front of the router. So I tried power cycling the router, the modem, the iphone. Still didn't help. So I tried "forgetting this network".....8 times. Still didn't work. So I tried power cycling the other things couple of more times. Still didn't work. I went into the router (and even though the settings hadn't changed since my last usage) and reconfigured everything. Dropped the speed (Netgear N300) from 300 to 54....didn't work. Tried dropping the security keys......didn't work. Switch from auto channel to a specific one.....didn't work.

So I am at a loss for words (although my paragraph is a bit run-on sentence-y)

anyone....help?

Doesn't surprise me. When I upgraded from Windows Vista to Win7 I had to change security on my router from WEP to WPA2 as Win7 did not support Wep

Hi Sujin,

I am no tech wizard, but I followed the instructions to change my wireless security settings (not "reset network settings") to WPA2.

I can't quite tell from your post if you've tried this solution. If not, I would try this as the very next thing, since it did fix my identical problem, and seems to have helped others as well.

Hey Strep,

thanks for the suggestion but I have already done that.....to no avail. Got a genius bar appt tomorrow but I am dreading the "it operates within normal parameters" speech.

Hi all, I had the same issue with my new out of the box iPhone 4s. What was really p'ing me off was that I still had my 3s and that worked fine.

So after reading loads I changed the channel from auto to a fixed number, in my case 10. My router is a netgear / virigan media super Hub.

I did this at 9am today and it's now 3pm and its all still working as it should.

I'll let you know if anything changes..

Good luck

Just advising also, the same applies with WAP (aka WAP-1)... the iOS6 update no longer will connect to a WAP WiFi - you must also change your router security to WAP2. I had been using WAP because my TiVo would previously not connect with WAP2, but (thankfully) TiVo have updated their software so it also works with WAP2.

I have the same problem. Recently I have changed my wireless security setting from Wep to Wap2 because I found an intruter to my network from the neiboughot. Since the change my iPhone 4s does not connect. the iPad itnis ok and reconnects! Any advice please? The iPhone is 4S and running Version 5.1.1 please help!!! Thanks

Hi,

I fixed my issue.... I simply changed the Channel from Auto to a fix number..... This resolved the issue for me.

Also, I installed IO6 and did a factory reset on my router. The channel is set back to auto but I am not have any issues.

This maybe due to the fact that the reset would have cleared the routing tables which could have been causing the problem to being with.

Set 1:

Do a factory reset on your router

Set 2 if 1 doesnt resolve your issue:

Set the Wifi channel to a fixed number not auto.

Set 3:

Upgrade to iO6.

or all of the above!!!
