wifi doesn't work with IOS 7

iPad 3 user here. After upgrading to iOS 7, my wifi connection doesn't keep. After the device goes to sleep for long time, it can't reconnect automatically after waking up. The problem persists with 7.0.3.

Last night, I found a workaround. I was using MAC filtering on my router. After I disable it, my iPad wifi seems to be persistent now.

Just a thought. I checked my router configuration. The problems with connecting may have something to do with the WIFI settings. My router channel is set to auto where the router will pick the optimal frequency using some mysterious algorithm. I have also set the router to broadcast the SSID. Perhaps the problem may be that IOS 7 needs to find a broadcasting SSID in order to enable WIFI and allow connection. That may explain why it works in the Apple store but not at a private residence. The Apple stores broadcast the SSID, a home system may not because of misguided concerns about security. Broadcasting an SSID is not a significant risk and setting the channel to auto is probably a good idea.

The plot thickens. I got wifi on today. This will sound lame but I can't remember where I found someone's directions on how to get wifi working. The original list did not work but someone posted an additional step and it worked. Remember though, my wifi worked (not grayed out) on Tuesday too and then when I got home it quit (grayed out). So I will have to wait and see if it will fail again.

Here's what I did:

1. Turned off Airplane Mode (if on)

2. Turn Cellular Data off

3. Reset Network Settings via General, Reset, Reset Network Settings

4. Wifi was up and running and immediately picked up my home network

After it was up I tested it by opening up Safari and going to a website. I don't see any problems right now.

I am NOT convinced that this is a solution yet because of (a) I tried pretty much everything multiple times before and (b) everyone else seems to still have the problem.

I AM convinced that Apple is lame on this issue: the iOS "upgrade" is the villian on this, and, Apple still has not address what is beyond a doubt obvious problem - because the procedure they give for this did not work for me nor most on this thread.

I will keep you posted. BTW - if in fact the hardware is damaged from this iOS deal then Apple will feel the wrath of me and thousands of others. This is not one of those "isolated" issues. My 12 month warranty expired 4 weeks ago and I have 11 months to go unless I want to pay AT&T an ETF. If I bought a replacement phone for $198 I would not want to have iOS 7 on it. And Acesinica, I understand why you may be happy with being screwed by this because of your "investment", but I don't feel the same way. If Apple doesn't fix this one way or the other then they will lose market share even faster than they are and I will be one of the ones who help that along. The one month over my warranty would cost me $198 and I would still not be convinced that my new 4S would be reliable. This is a game changer.

James,

I took my 4S out of its case and put it in a zip-lock freezer bag and placed it in my freezer for 15 minutes. When I took it out wifi worked, but only for a day or two. After freezing it couple of times, I found these instruction on this thread. After following them I have had no problems and wifi was restored. However, I am not going to download any more software updates that's for sure. By the way, make sure after you do this you keep bluetooth always turned off. Here are the instructions:

1. Turn off Airplane mode (if on)

2. Turn cellular data off

3. Reset Network Settings via General, Reset, Reset Network Settings

Hope this works for you.

apple please find a solution! 😐

Check out this article, follow it step by step. http://support.apple.com/kb/HT4199. It explains how to properly set up your router/base station with iOS and OS X. First, reset your router/base station to factory defaults (requires using a reset button on the device, or through the web setup utility).

iPhone 5 (not c or S); iOS 7.0.4.

My phone has actually been working decently since the "Big 7," but started getting glitchy after the latest .4 version. Lately, like many of you I have had WiFi drop problems. The last couple of days I have been unable to connect at all to our home WiFi (my daughter's new 5c and my wife's old 3GS seem to have no troubles or glitches) and I thought seriously about calling the Apple store - yeah, I was looking forward to that!

On a hunch, I did try something that has worked (cross fingers). I tapped the Reset button on my AT&amp;T Netgear 7550 modem - it's located just above the green Broadband port on the back. It's a small black button. Just take a toothpick or anything that will fit in that hole and gently push on the button until your modem lights blink a couple of times. Worked like a charm! The WiFi immediately reset.

Best to all -

FYI, resetiing my home router fixed my problem. My iPhone 5 and iPad running IOS7 will both connect now. I hope you all have the same luck with your issues. 😐

Reboot your router.

Removing the ' from my iPhone's "name" seemed to solve my wifi problem. I'm running 7.0.2 on an iPhone 5.

I put my phone in airplane mode and joined wifi no problem, I kept it in that mode for an hour then took airplane mode off, I've been holding wifi for about 30 minutes now.

Mine died at 7.0 so I think if you've already bit the bullet on 7 you should get the current upgrades, but don't do it via WiFi, use iTunes.

I have this issue on my iPhone 4 an interestingly on my MacBook Pro after installing the latest update for OSX.

Both of them say they are connected under wifi settings but neither are getting an IP address assigned via DHCP. If I manually assign an IP, subnet, router Ip and DNS manually then they both work fine.

I would agree Apple have broken something and manually assisting IP addresses isn't something everyone is comfortable with.

Best thing to do, if you have another working IOS device, is to take the network details from it (settings wifi then click on the wifi network you are connected to). That will show you the details you need. You just need to use those details on your non working device, but increment the first IP address by say 5 so that it is unique.

This may be harder on a corporate or uni network but at home it should be fine.

I hope that is of some help.
