I preordered my Black 64GB AT&T iPhone 5 from my Black 64GB AT&T iPhone 4S. I got the iPhone the day it came out. I had not had any problems with it, other than a battery issue here and there. Well, we have Comcast/Xfinity home internet, and about 2 months ago we received an email saying out download speed had been increased from 30mbps to 50mbps. When I ran a data test, I kept getting 30mbps. Well I soon found out that our DOCSIS 3.0 modem had been replaced with a DOCSIS 2.0 telephony modem a few months prior to this (Probably around January or February) when we added Comcast Voice to our package to give us the Triple Play package. I immediately contacted Xfinity to have a tech come out and give us a new DOCSIS 3.0 telephony modem. (I work at Best Buy and we have Comcast reps at our store, but I didn't want to buy that telephony modem just yet). So a few days later Comcast comes out to install the new DOCSIS 3.0 telephony modem so we can achieve the increased speeds. Well, ever since around that time that we got the new modem, which was around the time iOS 6.1.3 came out I belive, my iPhone 5 has been having major wi-fi issues. Major. I am able to connect to our WPA2 nework (AirPort Extreme connected to a Arris DOCSIS 3.0 telephony modem), but the connection is unreliable and slow. My iPhone 5 has been getting progressively worse with the connection too. The first few weeks the connection was so-so, but the past 2 weeks have been entirely miserable. Nothing loads on wi-fi. Not even a Tweet can be sent. So for the past 2 weeks I have been running off of my iPhone 5's 4G connection (Thank God for Unlimited Data) for internet since I am unable to use the wi-fi. My iPhone connects just fine to the wi-fi, but the speed is literally at a standstill. I will run speedtest apps, and so far, my fastest slow speed has been .50mbps for the download (Yes, you read that right) and .4mbps for the upload speed. Everything else is even slower than that speed. When really, I should be getting 50mbps download and 10mbps upload.
My 64GB Black AT&T iPhone 5 (iOS 6.1.3) can connect to the wi-fi, but it's speed is at a standstill. My Dad's Black 16GB AT&T iPhone 4S is doing just fine on the Internet. My Mom is complaining about internet issues with her 16GB AT&T White iPhone 4S here and there. My brothers have had a complaint here and there about their wi-fi on their 32GB AT&T iPhone 5s (1 Black; 1 White). My Black 64GB iPad 3 with iOS 6.1.3 can connect to wi-fi, but it does not work either. My 15" Retina MacBook Pro and iMac connect to the wi-fi just fine and are both getting 50mbps download speeds and 10mbps upload speeds.
So that's what worries me. The inconsitency of what devices are working on the wi-fi network. My Retina MacBook Pro and iMac are showing me that they can achieve great speeds, while my iPhone and iPad cannot get a reliable, usable wi-fi connection.
So I'm pretty sure from what I've read online that I'm not the only one experiencing these problems. My iPhone 5 and iPad 3 cannot use wi-fi whatsoever. And my iPhone 5 can barely keep a charge. I could have 100% charge, leave it unsused, but on, in my pocket, and 6 hours later it will be at at the most 50% for a charge.
Apple, please look into this. My battery life is horrible and I cannot use wi-fi anywhere. The speed does not work. My connection is at a standstill. I have the connection, but it does not work.
Thanks.
