IPhone 4s can't connect to wifi after iOs 8.1.1

So yesterday I updated my iPhone 4s to iOs 8.1.1 and now it seems like it doesn't connect to wifi anymore. It shows the wifi-icon on the system tray, and when I go into settings/Wifi/*Network* it shows all the correct data. I already tested it on 3 different networks, and all the same problem. I just drains my cellular instead :/
I already tried hard reset and network settings reset

I have iphone 4s with upgrad to 8.1.1, coudn't connect to App Store. Each time I put password in utilities screen it would disappear.
I don't know which part worked but I cleared the safari history and cookies and enable location and it worked.

Can't connect to wifi after IOS update. Do you know a solution?

Loaded the new update and now it is sporatic connections with the wi fi. I have unplugged the router and all that, still no luck. It will work normally very briefly, but only briefly after I unplug the router, etc.
Do any of you have a solution to fix this?
Thank you!

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.

IPhone 6 can't connect to WIFI anymore

Ok, since my iPhone 5 has been updated to 6.1, it can't connect to WIFI networks anymore and from time to time restarts for no reason.
I tried to restore from iTunes, and now I wan't to back it up from iCloud, which can't happen without WIFI.
Can anyone help me with this issue?
Thanks in advance!

I have the exact same problem. There are countless other threads on this and I have tried all the tricks in the book to get it to work again. With no success. I cannot connect to any wifi router (home, work, public...). I also restored the phone various times and now can't backup from iCloud because of missing Wifi. This is extremely frustrating. I really hope Apple puts out an iOS update very soon as this issue as all but new.

IPhone 5s won't connect to wifi after 7.0.3 update

I updated my iOS last night to 7.0.3, today i can't connect to wifi. All my other devices and laptop are connected to this same network but i can't join on my phone.

Heya risch, what follows are two experiences both I my brother had with this problem. It seems this issue is so widespread that two people can have bought thier iphone from different sources and have the exact same issue, with varying outcomes.
Worst case first, my brothers iphone. He updated to 7.0.2 and found he just couldnt connect his wi-fi. He was terrified of losing all his (over 1000) contacts so he decided to take his phone in to the local Telstra (Australia) outlet. The guys there tried all sorts of things and finally conceeded and sent the phone back to Apple. Apple to their credit did not question or quibble, they sent out a likley refurb'd or new iphone 4s to my brother then next day.
My issue (now solved) was about the same, though I had just updated to 7.0.3, I just could not get wifi to connect. Finally I decided to delete our homes wifi connection from my iphone ie: "Forget Network", then with the details taken off my computer and ipad I rejoined our home network and simply punched in our network password and bang!. It worked.

Can't connect to wifi after connecting to Starbucks wifi

I know it sounds awkward that I can't connect to any wifi network after I connected to Starbuck's at&t wifi network, but that is the last time I've been able to. I'm not sure if it's just a coincidence or if that is the reason I haven't been able to after this. I had 2.1 since day 1 and it worked always perfectly until Starbucks that one time. A few days later, I updated to 2.2 and still everything is fine except for the wifi, same issue.
Issue: Wifi is on and it just keeps showing "Choose a network..." with the icon spinning, but no networks show up. Ask to Join networks is on, but when I go to any program, it doesn't ask to join anymore. I've tried resetting network settings, turning on/off normally, doing a hard reset by holding down and not turning it off normally. I don't know what else to try. Nothing with the network router has changed, but even then I would expect it to list it at least or show all the other networks around the apartment, but none show up. My wife's phone connects to it fine. I've also tried clicking on Other... and then putting in the network name and it doesn't find anything. Something is abnormally wrong.
Any ideas would be appreciated.
Thanks.

Hmmm.....
It's worth a hard reset (press and hold the sleep/wake button and the Home button together, ignoring the 'slide to power down' message and then release them when the display blanks. Press the sleep/wake button until the logo appears and then wait for the restart which takes a little while...)
Apart from that, it may be worth clearing Safari's cache, etc..... (Settings > Safari > Clear History/Cookies/Cache)
In any event, 'Good luck'!!
If all else fails it IS possible that some WiFi hotspots are VERY hot and emit more power than is really allowable in the Standards, resulting in 'frying' your WiFi receiver (possible but unlikely). If this is the case, return your iPhone to an Apple store with the 'WiFi not working' message but don't mention Starbuck's or anyone else.....just don't use Starbuck's WiFi service ever again!

Can no longer connect to WiFi after IOS 7 update

I own a small hotel. After updating to the new IOS, no one can connect to the WiFi network on their iPads or iPhones.
Help!

Too little info here to work with however ...
1. Go to SETTINGS on your iphone, then to WI-FI
2. Can you see any networks listed? If not, then you have a problem with your Wireless Router. Reset it and see if it appears.
3. If you can see the wireless network, try to connect to it manually. If this works, then off you go. If not, then you need to tell me what wireless router it is before we can go much further. Also, are any other devices connecting successfully (ie: pre-iOS 7 handsets, Macs or PCs)?

Still can't connect to WiFi on iOS 6 iPhone 4S?

I have read all the workarounds for convincing iPhone 4S updated to iOS 6 to connect to my wireless network and it still will not connect. I've used it in other places with no issues (networks with no security) but I can't connect to my home wireless network (Airport Extreme). My other devices connect fine and there were no issues before upgrading but I have tried restarting the Airport anyway and changing the security settings and still nothing. Half the time when I go into WiFi settings on the phone, the network doesn't even show up in the list. Whenever it does, I try to connect and either get "Cannot connect to network," or I am asked for the password and I enter it and I get the same error message. I've tried resetting my network settings and doing a soft reset of the phone but nothing seems to help. I also tried removing security on the wireless network completely and it still can't find the network or connect to it.
Has anyone found a workaround for this short of reseting/restoring the phone or a problem with the Airport Extreme that might be causing the issue?

Update: I tried restoring the Airport Extreme to factory settings and used a new network name. It connects at first, but then loses the connection after a minute or two and the network disappears from the list...infuriating.

IPhone 5 can't connect to wifi

Just got my verizon iPhone 5 and the first night I was able to connect to the wifi at home now I can't. My iPad connects with no issue so its not the wireless. The phone just keeps saying "can't connect"

You're not the only one with wifi problems. https://discussions.apple.com/message/20452450#20452450 My iPhone5 says it's connected but it clearly isn't as it doesn't connect to any online content.
Turning off 3G solves the problems I have with connection and a similar problem as described here http://biltawulf.wordpress.com/2012/12/11/wifi-problems-with-ios6-a-little-warni ng/
Not the solution we're looking for, is it?

Can't connect to Wifi after restoring factory settings and restoring backup (internet on computer working just fine)

Want to die. I've wasted my entire Sunday trying to connect to Wifi on my phone. I tried the reset network settings, restored the phone to factory settings then restored the backup and still no game. I have restarted the **** thing and am very frustrated. Every time I've updated my software with Apple I end up having to replace my phone. I have an appointment with the genius bar tomorrow ,but hopefully someone here can help me so I don't jump in a river before that time.
