AT&T Inc. said a software defect is slowing down the wireless connection for more than one million customers looking to send data from smartphones like the iPhone 4 or laptop modems.
AT&T and supplier Alcatel-Lucent found a problem with Alcatel equipment that is preventing some subscribers from reaching their peak data transmission speed.
The companies said the issue affects less than 2% of AT&T's wireless customers, or about 1.75 million people. Alcatel-Lucent said it was working to fix the software glitch.
The glitch is the latest in a series of hiccups for AT&T, which is struggling with the perception that its network suffers from more dropped calls and coverage problems than rival Verizon Wireless.
Until a fix is completed, AT&T said some customers who previously were able to get a faster version of 3G called HSUPA could only get "normal 3G uplink speeds," which is slower. People affected include those who own a Laptop Connect card, as well as certain smartphones, including the Apple Inc. iPhone 4.
An AT&T spokesman declined to comment on which markets were affected by the network problem. The company had 87 million subscribers at the end of the first quarter.
AT&T has dealt with a number of glitches, including allowing the private email addresses of about 140,000 owners of cellular-connected iPads to be publicly released, as well as problems with customers attempting to preorder iPhone 4s. More recently, Apple has talked about the signal strength and antenna issue of its new iPhone 4, partly laying the blame on its carrier partner's network.
