iPhone 4S iOS 6.1.3 will not connect to or even find any wifi networks, any ideas?

You are really sure that WiFi is turned ON right?

On your iPhone try using Settings > General > Reset > Reset Network Settings.

If that does not solve the problem try the following:

1. Backup your iPhone using iTunes or iCloud.

2. Use iTunes to completely restore your iPhone as new. This will give you a fresh copy of the iOS software and you will need to go through setup again.

3. Go through the setup procedure and see if WiFi works again.

4. Restore your iPhone using the backup above.

5. Check your iPhone to make sure that WiFi is still working.

Hope for the best!

Note that if none of this works it would appear that your iPhone has developed a hardware problem. If so, contact Apple support.

Hi JimHdk,

I have also upgraded to ios6.1.3, and facing same wifi connecting problem, after upgrade my iphone3gs is connecting to my laptop shared wifi, which was working perfect with ios6.1.2,

and its not an hardware error, its software error, crippy apple does not test their releases which causes problem to users.

Updates:

Earlier wifi connection which i was using on my Iphone 3gs, was WPA2, which was shared from my laptop via "Microsoft virtual WiFi Miniport Adapter", was working perfectly till ios6.1.2, but when i have upgraded my iphone 3gs to ios6.1.3, my iphone 3gs became unable to join wifi,

Today I have created "adhoc network" on my laptop using "Broadcom 4313 802.11b/g/n"(default wifi adapter of my laptop), and kept security type "WEP", and found my wifi working fine with my iphone 3gs,

So if someone using LAN internet on their laptop, they can share their LAN internet to use on their ios devices, via creating an 'adhoc network',

How to create an 'Adhoc Network',
choose Security Type : WEP (compatible with ios6.1.3)

I am having the same problem. I have not dropped my phone or anything like it.

My PBP has no problem connectiong to the same networks. If I turn on and off the phone sevral times, it can occur, that for a short while, the Iphone discovers the networks and can connect to one of them, but not always. Mostly it does not work. Mostly it does not even detect the networks.

This is very annoying!

Obviously we need a new update to fix this bug!!

I have made a complete restore of the iphone. Problem with Wifi not solved. Button still is grey. Additionally 85% of the apps will not return to my Iphone. In spite of several restores

I do not enjoy the time spent on trying to make this phone work properly.

Like you guys i have Iphone 5 and before iOS Ver 6.1.x my Wifi worked perfectly.

since the upgrade to iOS 6.1.X my WIFI isnt working properly (while from the same sport my samsung Galaxy S2 will see the WIFI Network WPA2 AES and will connect Perfectly).

there are allot of suggestions of various forums on the net that the latest iOS update just fried the Iphone 5 WIFI Antenna.

As i understood the Iphone 5 is using Dual Band 2.4G / 5G Wifi Antenna Flex Cable.

if you will have a 5G Wifi Network Router all will work Properly.... but if your Router is 2.4G - Game Over.

for now i've oredered a new Iphone 5 WIFI Flex Cable and i do plan to replace it myself.

anyone can share his knowledge and confirm that this is the root cause of our problems?

Thanks.

I too have the same problem, and usually do after Apple releases a new version. When I figure it out I'm going to write it down!!!!

Don't bother buying cable if you haven';t we who see this problem with every release know it's apple's software. unfortunately i cannot remember the fix....K

i finally found where the problem is with " unable to join network " error message , after months of research and trying every single trick on the net not working , the problem is with channel overlapping from the router . i have downloaded " inSSider " network analyzer and found that my home network is overlapping with four other networks , though when i try to connect from another place where there is no channel overlapping it connects just fine . most routers use 2.5 Mhz frequency , so you get a lot of overlapping there , but if you try to connect from a 5 Mhz router , its fine . so you could download the inSSider app for pc and check for the channel where there is no channel overlapping and use this channel . This is a hardware issue anyway , if the wifi circuit and wifi antenna are ok in your phone then you should not have any problem connecting , but if either of them are faulty , you will get that error . so you either fix it or taking it to apple to replace it . and it is possible that when you go to apple store you would not see the problem , thats what happened to me , that is because they probably have a 5 Mhz router and that would rarely interfere with other networks .

I reset my network setting on my 4s and wifi is connecting again.

What did you end up finding out SuskH??? I'm having the exact same problems as you and I, too, have tried everything and I'm still not able to connect. Help!

I have encountered similar problem - I could connect to my wifi but cant access internet - The problem was due to overlapping of IP address and DNS - Just go to setting option- > wifi connection > select your wifi network > there is ">" infront of wifi network , click on it >, just see whether your IP adrress and DNS is same under DHRCP tab, if yes got to static option - copy your IP address from DHRCP and put your DNS as 8.8.8.8 its a universal DNS , work on all networks - try this your and phone will work fine
