iPhone 5 wifi issues

My iPhone 5 connects to wifi networks and remembers them, but receives absolutely zero data through the network. LTE and 3G no problem... Off to the repair shop (after 3 hours of ownership...) or any ideas??

iPhone 5, iOS 6

I was having a similar problem all day. Belkin N750 router, problem on both 2.4GHz and 5GHz bands. The iPhone 5 would connect (with security enabled on the router), but no data was flowing. Occasionally I'd get brief data movement and then it would die. Then after connecting and re-connecting a lot it all of the sudden works and things 'seem' stable. Getting a solid 23-24 Mbps now with the Speedtest.net app which I've run about a dozen times over the past two hours without problems. Of course at this point who knows if it will last.

Just noticed a problem of range with my new iPhone 5, received by delivery from The Apple Store earlier today. I live in a small 410 sq.ft. apartment. My iMac and my Apple Base Station are in my bedroom, at one end of the apartment. Starting with my iPhone 3, to the iPhone 4, to the new iPad, I’ve had no problem ever having a full signal when I go sit in my living room at almost the farthest possible end of my apartment from where the base station is located, perhaps 40 feet away. I’ve surfed the web, checked email, even used the Time Warner app to watch TV stations from that position without problem. I’ve even gotten the signal from my Wifi setup through the walls and out to where I catch the elevator, about 100 feet away. And this is not the latest Apple Base Station, but one removed. And, yes, I use passworld security on my network. I believe it’s WPA2.


About an hour ago, I realized that my iPhone 5 was on LTE when I was sitting in my living room, in the same spot where I’ve never had an Wifi signal issue before. Checked the Wifi setting and it didn’t see my network. I went into the bedroom and picked up my iPhone 4 and brought it out to that spot, and it had a completely full Wifi signal. The iPhone 5 was on LTE.


I then went back into the bedroom with both phones and started walking towards the spot in the living room. Less than halfway there, the Wifi signal on the 5 starts dropping. By the time I got just over halfway there, approximately 20 feet from the Base Station, the Wifi signal was gone; full signal on the iPhone 4. I then went to the living room spot, again the 5 had no Wifi while the 4 had a full signal, and started walking back towards the bedroom. When I got just about halfway there, the 5 started registereing my Wifi network.


I shut off the 5, then powered it up again to see if that made a difference. Nope. Same issue.


This is not an iOS 6 issue because I’d already upgraded my iPhone 4 to the new OS and it had no issues with Wifi in the 2 days since I upgraded; same reach and same signal strengths for me.


This is an iPhone 5 issue. On none of my previous iPhone or iPad purchases have I had to run through any hoops to get my usual full Wifi signal. I shouldn’t have to do a restore or a start from scratch re-set-up of my phone. I’m about to call Apple about this, though I’m not sure there’ll be anyone there to help at this hour.

All right everyone. Here are some progress that I made towards finding a pattern.


My iPhone5 will not browse the web neither in 2.4Ghz nor 5Ghz band with "WPA2 Personal" enabled as security. I can perfectly connect internally but Safari (or any other program) will not connect to the Internet. I cannot even open the router config page (192.168.1.1) on these bands.


Now, I have a Cisco E2500 router capable of opening a "Guest" network with a passcode. My iPhone5 works very well when connected to this Guest network (which of course does not used WPA2). I can browse the web with no issues at all.


Can anyone out there confirm this with your iPhone5??? Now the real question here is if this is a software or hardware problem. I am still planning to have my phone replaced tomorrow since I read people in this forums confirming that their iPhone5 are working without wifi issues.

I think this is definitely related to WPA/WPA2. My connection speed was less than 3 Mbps on my iPhone 5, and 20+ on my 4 and on my laptop. I turned security off on my router and the speed on the 5 shot up to 20+. I then switched to 128 bit WEP and am continuing to get 20+ Mbps. Hopefully Apple issues a fix soon, but at least there's a workaround.


I don't know if it matters, but I have a Belkin N600.

So here is my network setup. Cable modem -> latest gen Time Capsule(latest firmware). Running strictly N mode on both bands. All devices are on the 5GHz band. When running a continuous ping against my iPad, or my wife's iPhone 5, I get 0% packet loss. However, the same ping test ran at the same time to my iPhone 5, I get roughly 80% packet loss every time. I have tried both bands, and it doesnt make a difference. Guess I will be contacting Apple to get my phone replaced. This is insane! I haven't even had the phone for 24 hours yet. 😠

OT: The worst part is my wife complaining that I am "playing with the internet" again, lol. If Netflix goes down...

I have exactly the same situation as Joe Winn. iPhone 4S, iPad 2, various laptops all connect to wifi with no problem. iPhone 5 connects only if within a few feet of the router. If I walk only a few feet (like less than 10) away from the router, the iPhone 5 drops the connection. Have tried it at two different locations, with separate networks and different brands of routers, with same results. Have tried the various remedies suggested in this thread to no avail. Not even turning off all security on the router helps. Feels like an antenna or other hardware problem.

same problem here. joing belkin dual band n network shows signal 0. it seems working through the router but after reading some posts, it might be just going through 3G. not sure.

and I don't know what Apple used as 3G chip. it's slower. side by side comparison with 4GS on a same carrier. please update soon.

Apple needs to respond/address this issue quickly. Is this a hardware issue or a software issue...any network engineers out there that can give their 2 cent regarding this matter?...Can a hotfix on the iOS fix this issue. This is obviously not an isolated incident. With the inconsistency of the wifi problems surrounding iOS 6 and the iPhone 5s, it won't surprise me that it can be BOTH. I'm going to take mine back tomorrow for an exchange to see what happens. How can you mess up WIFI Apple!

I've been having problems as well with my iPhone 5. I have a Billion 7800N router (2.4ghz only) and an Airport Extreme (dual band). All of my apple devices (including my iphone 5) will connect to the Billion and surf the web happily. However my home Home Sharing does not work between any of my devices. If I use my Airport Extreme all of my devices, except my iphone 5, can happily surf the internet and I have Home Sharing working.


Interestingly my iphone 5 will happily do home sharing with the Airport Extreme but the web refuses to work (again all other devices have no problems accessing the web). I would be interested to see if this is a dual band issue.
