AT&T iPhone 4 upload speed fix expected in 2-3 weeks

post #1 of 25
Thread Starter 
AT&T, Apple's exclusive wireless partner in the U.S., expects in the next few weeks to gradually fix an issue that has significantly reduced upload speeds for some iPhone 4 owners.

The company announced on Monday that it has begun rolling out a fix for a software glitch that has caused slow upload speeds for weeks. The issue lies with Alcatel Lucent equipment, and affects users of Apple's newly released iPhone 4.

According to Reuters, AT&T will be implementing the "gradual" fix over the next two to three weeks. The iPhone 4 is the only handset affected, because it is the only smartphone that uses the network's HSUPA technology.

AT&T said that users in markets with the defective software will be restricted to data speeds no greater than 384Kbps until the fix is in place. That's an improvement from previous reports from users, who said their uploads were as slow as 100Kbps.

Earlier this month, AT&T revealed the software defect was at fault for the issues. The company said the issue has affected less than 2 percent of its wireless customer base.

"AT&T and Alcatel-Lucent jointly identified a software defect -- triggered under certain conditions -- that impacted uplink performance for Laptop Connect and smartphone customers using 3G HSUPA-capable wireless devices in markets with Alcatel-Lucent equipment," the company said. As a temporary fix, they provided normal 3G uplink speeds for affected customers.

When working properly, High-Speed Uplink Packet Access can allow theoretical uplink speeds of 5.76Mbit/s. The glitch does not affect download speeds, AT&T said.

Must be regional. I've never had a problem in Atlanta. Up or down.

I'm still confused by this. My 3G with iOS 4 (and without HSUPA) gets very low upload speed since this problem first occurred. So something else is happening here. I assume my iPad 3G has HSUPA, and I get under 100 KBS with that most of the time as well, but not always.

Not Apple - as you know very well.

Don't start in again!

AT&T mentions that only 2% of the users have been impacted. That is totally not true. How is it possible statistically. For eg. a single tower in Chicago or NY will have at least 10000 iPhone users connected in downtown area. Now count all the metros and all the other areas that have had the software issue. It is theoritically not possible forget practically. It is a tower issue so all iPhone users should be affected. Except it and move forward.

BTW, AT&T just so that you know as promised 7/28 is coming in two days. Hope to see the new tower that has been planned for like what (500 years )

What upload problems? I don't think anyone in Houston suffered this upload issue. Any of my people want to confirm?

IF, and I say if, it's true that only iPhone 4 users would have this problem, and if it's true that the equipment that has this problem is only in a few areas of the country right now, then it's entirely possible that it only effects 2% of the users.

The question is whether it's only affecting iPhone 4 users, as my old 3G seems to be affected along with my 3G iPad, though there are only about 500,000 3G iPad users using 3G on AT&T's network right now, from their numbers, a drop in the bucket.

They've already fixed it here in the Medford area of southern Oregon. My upload speed on 3G was in the low 100 kbps a week ago. But I just checked it and got and average of 1340 kbps (and 4424 kbps download speed!) with three different tests with the SpeedTest app.

BTW, you can count me among the 73% of iPhone users who are very satisfied with AT&T.

It's just good to know that Apple (as well as one of it's biggest partners - AT&T) are doing all they can to keep the fixes/improvements coming.

Ultimately, it all reflects upon the user experience for Apple's premier product, the iPhone.

2 - 3 weeks for a software fix? I think they just did not want to handle all the iPhone 4 launch traffic for a while.

BTW it does not seem very wide spread. I only heard friends of friends experiencing the problem. My guess it's NY and San Fran once again that are getting hit.

That explain why the internet on my iPhone was that slow. I am glad they are trying to get things right.
I hope next time they do more testing and all this bugs like internet upload speed, antennas problem, etc will not affect customers.

Putting on my conspiracy theory hat... What if this was intentional throttling in anticipation of the ip4?
2011 13" 2.3 MBP, 2006 15" 2.16 MBP, iPhone 4, iPod Shuffle, AEBS, AppleTV2 with XBMC.

Right. Alcatel-Lucent is letting their name be drawn into this even though it's AT&T throttling iP4 users. Not.

Just let the vendors work the issues.
Bitching and conspiracy theories contribute absolutely nothing.

It might be that its affecting the upload speeds of all 3G devices, but its less noticeable on HSDPA devices with only 384Kbps theoretical maximum upload rate.

The iPad WiFi+3G only has HSDPA and three UMTS bands. If I recall correctly from iFixits breakdown its essentially the same Infineon and TriQuint chips used in the iPhone 3GS.

I don't know, but it's pretty noticeable on mine. Before this problem, I was uploading at over 300Kbs most of the time. Now, it's more like 50 Kbs most of the time, rising to 80 or so, and dropping to as low as 6.

Generally, the iPad does somewhat better, but not by much.

Already fixed in Detroit.

What's interesting about all this for me is that while the download speeds vary widely depending on the traffic from all the phones in my cell tower area, the number of iPhone 4s are probably still a small population so the upload speeds are HUGE right now....4600 kpbs on average for me.

Looks like it's already fixed in Seattle:

Last week-
Down 2.03 Mbps
Up 0.10 Mbps

Today-
Down 5.61 Mbps
Up 1.61 Mbps

Yes - two to three weeks - because with enterprise equipment that is used to handle transactions such as cellular traffic that generate revenue for the company you don't just shut it off in the middle of the day. You have a change control process and change windows that have to be scheduled for the middle of the night and or weekends - and you have to do a backup before hand so that if something goes wrong you can revert. And they may even have temporary hardware that is put in place to handle the load while the upgrade is done - or a cluster of equipment that all needs to be done but has to be done in a round robin fashion so that it does not all go off line at the same time. While it may only affect 2% of users - there might be a dozen systems in a dozen locations that all must be upgraded - and then tested and verified after he upgrade is complete. It is also possible that they have only a small team handling this upgrade and it is possible that they have to physically travel to each of the affected areas (although it is also possible that it is all managed remotely).

The world of enterprise computing is a different place that your personal computer at home where you can boot it up - shut it down - or install new software anytime you like.

Lies, Lies, Lies Lies Lies Lies Lies, and and more Lies.

It has absolutely nothing to do with software. My iPhone 4 was getting 1.5 mb Up until AT&T pulled the plug on that, over the air, and dropped it down to a 100 kbps.
