iPhone 5 wifi issues

I also had an appointment today at the Genius Bar. It does deffinetly appear to be a hardware issue. I had two new iPhone 5's. One worked flawless from the initial setup while the second couldn't find networks, couldn't maintain a constant connection, and could never reach full connectivity aside from standing next to the router. I noticed the difference immediately during setup since the bad device was the second to be setup.

So today while working with the tech at the Genius Bar, it was evident right away. The phone didn't find any networks right away. Finally it detected limited strength connectivity to their Apple Demo open network. Once connected, the speeds were horrendous. The tech agreed and swapped the phone out for a brand new one. The one works as it should, perfect. I don't buy this is a wpa2 issue since the wifi receiver isn't doing it's part. Either way you should never be asked to compromise security to enable a device in this day and age to work as expected. Do yourself a favor, don't waste anymore time on this, go in there and demonstrate your phones problems. They get it, it's pretty obvious and Apple is more then willing to swap out the phone. Now I am happy and can move on.

I am having a similiar issue. I just verified that my Iphone 5 wifi download speeds are averaging between .35 mps 1.34mps on my 5 ghz and 2.4 ghz wifi connections. My Iphone 4 is averaging 9.5-11.50 mps on my 2.4 ghz connection. I am getting between 9mps to 35 mps on the LTE network. I hope there is a quick fix on the way.

Damnit i was hoping i wasnt gonna find this....Having the same problem first this distort on the screen was happening but then it stopped and now the wifi :/ my nephew was next to me going to town with his ipod and im here with no connection. Ill give it till im off then im calling apple. This is bull.

I had the same issue of slow WIFI connection at home after iOS6 upgrade. I resolved it today after playing with my router. I have a first-gen Time Capsule as my router. I believe the only change I made was to change the WIFI Radio Mode from mixed mode (802.11n (802.11b/g compatible)) to 802.11n only (2.4 GHz) and restarting the router. Security remains WPA2 Personal.. I've been getting full speed connection ever since.

Hope this can be helpful to others.

I think we have 3 different wi-fi issues here, 1 that has been fixed and 2 others.

The first one was when apple accidentially took down the webpage that iOS uses to detect if it can reach the Internet. Apple fixed that days ago.

The second is a hardware problem with antennas. The symptom is weak to no signal. No work around, other than be very close to your access point. Go swap out your phone.

The third is a software problem. Symptom is extreme packet loss when using WPA2 networks. The work around is WPA/TKIP, WEP, or no encryption.

Apple hasn't acknowledged the second or the third problem.

I found out something that might be useful in evaluating the problem.

I'm experiencing problem 2 (probably) and definitely problem 3. Regarding problem 3, I just realized that I can get push notifications from apps but can't access the internet either through safari or through apps that access the internet (e.g., facebook).

Was mine the 4th? (see one above your post)

I'm going to bet it's related to the WPA2 issue. I'll have to go look at the N spec, but I'll guess N doesn't support WPA/WEP, and by forcing N the phone goes down a different code path and doesn't exercise the bug. I have no idea if this accurate.. just an educated theory.

I've been on multiple networks all weekend, and my 5's pulling MUCH slower connections than my wife's 5, or my macbook pro, my neighbor's HTC EVO, or his wife's iPhone 4, I've confirmed it at home on my personal network where I know I'm not having problems with the network, my 1st gen ipad is faster, my MBP is faster, my wife's iphone5 is faster....

the real insult here is...my iphone 5 is faster on the verizon 3G network than it is on my 12 meg DSL connection!

please, if there's a solution, let me know. it's NOT all about WPA2 btw, because the networks I've been on all weekend were open networks, and my airport extreme is set up on WPA, not WPA2

Same Problem in a way but mine is with the data my iphone 5 keeps switching between edge and 4g but we have 4g where i live and my mom and sisters iphone 4s have 4g all the time and its like killing me....

Maybe you have problem #2 - bad hardware/antenna?

How did you configure your airport extreme to only WPA? I only see WPA/WPA2 or WPA2. WPA/WPA2 allows clients to use either. I don't see a way to force WPA.

Hello!

Sorry a lot of you are having issues with connecting via wifi. I have the Linksys E2500 router and had issues connecting via WPA Personal with AES encryption. I switched the router to WPA with TKIP encryption and it worked flawlessly. I also changed it to WEP and connected with no issues as well. The issue is keeping a sustained connection with WPA2/AES as some have discovered.

Today, I went to the Apple Store and told them about the issues I was having, which was connecting to routers that are WPA2/AES. The guy understood basic networking, so this was helpful. I told him my problem sounds like several who have already posted on the Apple Forums. He quickly found several discussions relating to WPA2/AES issues and agreed I must have a bad phone if I am having problems keeping a solid connection. They replaced my iPhone 5 (32gb) without any hassels. Now, it wasn't until I got home that I could test device because they did not have a WPA2/AES setup in the Apple store. Fortunately, my new phone has no issues connecting to WPA 2/AES at all, so the riddle has been solved and I am happy now.

Does anybody know if this is hardware or software related? I believe a bad batch of phones must have been released before Apple could correct.

Thanks and hope this helps!

Well if this is true, then it means that both of my replacement phones have the same hardware flaw as my originals.. and that I have really bad luck.

What is everyone using to measure packet loss? I just made a video of my 2 iPhone5s vs iPad2 on speedtest.net that I'm going to take into the apple store. Is there some other app or website I can use for packet loss?

My wife and I just left the apple store concerning her iPhone 5, her wifi would not work on our home network. No matter what we tried. They didn't even attempt to try it because I told them I tried it all. They replaced her phone. My iPhone 5 had a loose power button, I could wiggle it. I told them this is a new phone and it shouldn't be doing that. They totally agreed. They replaced my phone on the spot as well. Kudos to apple. Great customer service!!!!!

I was having long ping times, slow download (went from 28.0 mbps to 0.15mbps). I finally figured out that renewing the lease fixed it. Like a charm. Didn't read above thread to see if this was already discovered, but it worked for me.
