I finally got sick of finding my phone on 3G, so setup the guest wifi network on my WNDR3700. Instead of specifying WPA2 (AES), I used WPA (TKIP) and sure enough, my phone now connects to the guest wifi nearly instantaneously. So far zero failed connection attempts. Definitely makes me think there is an authentication/handshake issue going on with WPA2 (AES) protected networks. What are the rest of you using for authentication/encryption?
Not sure why iOS 6 worked perfectly (and found more wifi networks) and iOS 7 doesn't but at least this seems to fix my issue.

Apologies for maybe being stupid BUT I suddennly have the same problem with my iPhone 4S & iOS 7.0.3 regarding the non connection to WiFi.
I want to reset the Network Settings but it asks for a passcode. Which passcode must be used as I dont have a 4 digit passcode at all

Sorry I was STUPID - the Passcode needed was the passcode to get access to my iPhone - just forgot about it ..... BUT resetting the Network Settings on my iPhone 4S (iOS 7.0.3) does not solve the WiFi problem!!
Funny enough my iPad's WiFi works & is also upgraded to iOS 7.0.3 - mmmm THIS IS MIND BOGGLING!!!
WISH someone can help with the iPhone WiFi - it worked till this morning & suddenly was not available any more

This should fix wifi + battery issues

^^^ Unfortunately, that doesn't really fix anything.
Most of us have tried resetting network settings and even the phone and it doesn't work. Anyone that has had success with this is probably due to coincidence. In my opinion, the problem seems to have to do with connecting to WPA2 (AES) protected networks, possibly a timing issue with the protocol/authentication handshake. If you attempt to reconnect enough times, you will eventually reestablish a connection, but I suspect that iOS eventually stops trying to connect to a network after a certain number of attempts.
So far I've had *zero* problems connecting to my WNDR3700's wifi network after creating a guest network with WPA (TKIP) security, versus WPA2 (AES.) If I try to connect to my main wifi network, which is setup for WPA2 (AES), then the phone refuses to connect about 90% of the time.

Thats really cool but it doesn't actually fix the problem, it side-steps the issue... Mine wont even switch wi-fi on...But a lot of persistant badgering of apple has resulted in then agreeing a free of charge repair... And why not, they created the problem. So I'm back on my reliable iphone 3 while I await the result.

I have also the same issues on iPhone 4s, ios 7.0.3. Won't connect to wi-fi, some apps not working, apps not updateing, battery flat in half a day.
and we can't turn on the wifi switch.

I am also facing same issue.
I am having iphone 4s. I have upgraded it IOS 7.0.3 after that I started facing issue with wifi access. My phone always drop connection to the wifi. While trying to connect, always I got error message as "Unable to connect to wifi". Is there any way I can go back to ios 7.0.2 or any fix to this issue? If I keep on trying, after 20-25 attempts, it will get connected to wifi but again will drop it and same issue reoccurs.
Help is highly appreciated as I used to work from phone and it's stopped as it is not getting connected to wifi.

Hi guys, so glad someone posted this topic!
I've been having this problem with my iPhone 4S as of late with the update and the symptoms are:
1) Cannot connect to the wifi in my house, but wierdly sometimes I can connect and sometimes I can connect to the wifi at my university but that seems to be a rarity.
2) I can't swipe the wifi button which you use to turn the wifi on/off which means I can't even search for a network or change to WPA or the like.
3) Frustration is at it's peak!

Turns out the wifi antenna eventually got fried....
After a lot of intermittent flaky behavior (choppy settings, no networks found, settings disabled, etc.) eventually the antenna failed completely and the settings greyed out. Fortunately replaced under warranty. The Apple Genius claimed not to be aware of issues with the 4S and also suggested updating to 7.0.3 but I can certainly say that the problems happened after 7.0.3. (on a 4S that was only a week old and replaced because of other issues.) Two replacements in a month.... something in 7.0.3 makes the wifi antenna run hot and fail until it fries out.... so will remain on 7.0.2.

I got the iPhone 4S & upgraded to iOS 7.0.3 and lost my WiFi function. Tried ALL advice given in every possible forum found WITH NO SUCCESS until someone gave me the following tip. I laughed at the person but in disbelief I did what was told ....... AND IT WORKED & MY WiFi is operational again.
Advice given: Wrap your iPhone in cling wrap to keep moisture out & put it in the deep freezer for 20 minutes. Take out of freezer & unwrap from the cling wrap & voila the WiFi is back. Latter was my happy experience.
