  • AT&T Blames Slowdown on Software


    [UPDATE: AT&T claims, on their Facebook page, to have "implemented an alternative" somehow that "provides normal 3G uplink speeds and consistent performance for affected customers." Is it true? Post your results in comments.]

    According to a statement just released by AT&T, the cause of the widely-reported slowdowns in iPhone upload speeds has been traced to a software defect in particular cell-site gear. The problem with Alcatel-Lucent UMTS base stations that they say "impacts less than two percent" of all AT&T customers "under certain conditions." There is a fix coming, the company says, but won't say when, other than that there is a "definite timeline" for it. Somehow, however, they claim to be providing "normal upload speeds" anyway.

    The upload speed crunch was noticed starting late last week in some larger cities, with reports pouring in from less-populated areas as the holiday weekend wore on. iPhone 4 users that had been enjoying uploads in the mid-1.5 Mb/s range were suddenly seeing performance throttled to 100 kb/s. Other users in the same geographic areas were seeing no effect, leading to the conjecture that the problem was relegated to particular cells. Today's statement, apparently sent to everyone who inquired with AT&T corporate communications about the issue, confirmed that, saying that firmware on Alcatel-Lucent equipment was to blame for problems.

    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. This impacts less than two percent of our wireless customer base. While Alcatel-Lucent develops the appropriate software fix, we are providing normal 3G uplink speeds and consistent performance for affected customers with HSUPA-capable devices.
    In a further statement to Matt Buchanan at Gizmodo, an AT&T rep said that the carrier does not "have a definite time for the Alcatel-Lucent software fix to be complete at this point; we expect to know that soon."

    thanks to yoTelefono "Quatro" for the tip.

      When is AT&T just going realize that they need to put some serious money into the network? ever since the iPhone came out their data network has been plagued with problem from over-usage. Maybe AT&T is just holding their towers wrong...
      maybe all of the other retards will join me, huh?

      Come on guys, get a little PC around here. I know most of you are a little more intelligent that calling other people retards.

      Apple needs to announce a public release date of the 4.0.1 firmware update. Because the faster they come out with this update, the more will be clarified as to weather the upload speeds and the antenna problem are really a software issue.

      Lately my upload speeds have been unreliable, but my upload speeds continue to be 5 times faster than my 3GS.

      I get two very different speeds using different apps... I tried this a couple different times and the "Xtreme SpeedTest" was higher by far every time.

      Speedtest.net app gave me 1536 down / 240 up

      "Xtreme SpeedTest" App gave me 2420 down / 244 up


      that was in the exact same spot, 1 min later... wtf

      But not much better on my AT&T home Internet

      I haven't seen any problems with 3G upload speeds here in the Ukiah area in Northwestern California. I average 1200-1500 up.

      "they say "impacts less than two percent" of all AT&T customers"

      two percent of AT&T customers is millions and if it's only uploads why are so many people reporting it .

      All the more reason Apple will NOT speed up release of this update.
      1. Apple knows damn well that a software update WILL NOT FIX the "death-grip" issue, unless the update contains some "magical" way of re-routing the physical antenna connections within the phone.
      2. The update will fix the signal bars, thus showing how crappy everyone's reception really has been. The iPhone has been inflating reception strength since the very beginning, and now everyone will see how much worse an iPhone's reception is compared to other phones on AT&T's network. Who would be to blame for that? Apple.
      3. The longer Apple holds off on releasing an update, the longer their jail-breaking iPhone 4 customers suffer. Trust me when I tell you Apple loves nothing more than to make jail-breakers suffer. If you jail-break, you are using your iPhone in a manner that conflicts with how Apple expects, no, dictates that you use it, and Apple will do everything it can to stop you.
      I'm sure this list could be made much longer, these are just the reasons that come to mind the quickest.

      Don't be surprised when a ModMyI super-moderator/Apple fanboy comes along and claims that 2% is menial and not worth mention - just like the 2% of AT&T's smartphone users affected by the dropped unlimited plans were menial and not worth catering to.
