iphone 5s 8.3 wifi issues(STILL!?!?)

I too have a similar issue for many month, I've lose hope and I think it'll never been fixed.

Either it connects but the speed is near to zero (and speedtest doesn't work) or it says "bad password" or "cannot join network"

Funny fact it works if I'm very very close to the router..
I've also restored many time, even tried beta version, same.

It still could be your router, even if other devices are connecting. There are many threads here with many solutions to try. Have you checked them?

Have you tried rebooting your router? Have you tried changing the broadcast channel? Have you checked to see if there is a limit on how many devices can connect at once? Have you checked to see if Mac address filtering is set up on your router? Have you tried connecting to other wi-fi networks with your phone, such as at a Starbucks or a public library?

I tried more or less everything legal I found ... nothing worked ....

It works at my house now with my new ISP (new router) and all friend that have the same router, but didn't work with my previous router (or friend with the same router). It worked at work before, but not anymore (and they didn't change router or encryption).

I'm not sure I've the same problem than other because on the routers were it doens't work, it'd work if I'm very close to the router... I don't see how it could be hardware (like wifi Antenna), otherwise it won't work on some routers. When I called Apple, they told me to give 240$ to have a new one, because it has > 1 year, and to restore my phone ... Last point : it seems that the WIFI works on network I've never been before (new places), so I suspect some weird broken configuration files that are not deleted even with a restore ... I've no idea :-(

Add me to this listed of unsatisfied customers who have wasted numerous hours searching & waiting for a fix to this wifi issue.

My old iPhone 4 with ios 7.1.2 is working; my old iPad mini has always worked AND continues to work WITH ios 8.3... But NOT the iPhone 5? Unbelievable!!! I don't have an extra $300-$400 laying around to buy an iPhone 6 that MAY work!

As of an hour ago (+/-), my iPhone 5 will not stay connected to my home WIFI system. I haven’t touched a single setting on any device (iPhone 5, MacBook Pro 2012, or Modem/Router Combo DOCSIS 3.0). I also haven’t downloaded the update that appeared today. I’m now being prompted to input my stored password every time it tries to connect; which is every few seconds. I cannot isolate the issue.

Maybe it’s a good thing I have a Genius Bar appointment tomorrow to finally get the battery replaced as part of the Battery Replacement Program for iPhone 5 models. This also has the home screen wake/sleep issue, but I don’t want to send it away for a week. I’m really disappointed watching the sheen & luster rapidly fade away from what used to be a bright, shiny apple.

Prior to today, I never experienced the frequently discussed WIFI defect.

I am having the exact same, word for word issue. I can't be told to check router (every wifi connection not just at home) again. I'm not alone, and I'm through with Apple. This is the last. I'm broken hearted over this and will seriously grieve when I get the Galaxy in October. If you find anything that works please let us know. I'll do the same.

Every phone and OS is going to have issues. The problem is that unless the issue is present on every device, it may be difficult for the developers to reproduce the problem and fix it reliably. The best option to try and fix it is to restore as a new iPhone and see if the issue is present with nothing else installed. If it doesn't work then the wi-fi antenna may be faulty and you would be covered under warranty. If it works fine, start installing your apps one at a time to see if a particular program or combi of apps brings the issue back.

New solution posted yesterday - worth a try!

Re: Iphone 6 won't connect to wifi .. Says incorrect password which is not true. Ideas???

Have a 5c with verizon. Started have problems connections to wifi. 5c would connect then drop over and ever. Cam to this post and it led to to a post that said "Update to iOS 8.3" and problem would go away. I read up on 8.3 it said "it fixes devices that are having cellular and wifi connection issues". So I updated thinking it would fix my phone, and it did.........for thirty minutes. The phone did a reset and when I started it back up it was worse. The bluetooth would not come and the cell data would not turn off. I had to delete most apps cause it used all my data. When i would put the phone in airplane mode it would come on and boot back off. I now have a crazy $200 data charge. i have no clue why this is happening. I called apple and the basically told me to but a new phone and they are not fixing THEIR!!! software malfunction for free. The apple girl i spoke with over the phone was very very rude about the matter. I WILL NOT! be buy from apple again🙂 P.S:: THIS IS CLEARLY AN APPLE PROBLEM✅
