    Thumbs up AT&T 4G trouble

    I post this question before seems to be did not reach the right people to get an answer. After I order My Infuse, I did some research and found something that most of you may not like it. AT&T is not ready for 4G speeds yet even though they have phones available for it. They put restrictions on Inspire HSUPA+ speeds. They rumored that Atrix is coming out with same upload restriction. I do not know if they are going to remove this cap when they complete their upgrade or not. But for now Inspire data speeds are worse than 3G phones. Dorian may have some insight over this issue and I hope they will fix this eventually?

    PS:I did not receive my phone yet, but I will let you know if these allegations are true.

    It is indeed true. Without a custom ROM you are restricted to sub 400 kbps upload speeds.

    Well, HSPA+ in all it's variations is limited to 5.76Mb/s in the uplink state. So that works out to around 400KB/s upload speeds. There's actually no limiting... besides the limit of the standard.

    Dorian, with Rooted, custom ROM'ed Inspire I am seeing 2300kb/s down and 1300 kb/s up.

    kb... not KB. Big difference. Bit vs Byte. Those speeds are about right, depending on how the tower you're connected to, is equipped.

    Hmm. I wasn't aware of that, and I handled this phone well before release. From looking through XDA it looks like an APN issue... not a modem or hardware issue.

    The Inspire I field tested got routine upload speeds of 1500-1800kbps around the Birmingham and Atlanta areas.

    Hi Dorian. Do you know if DFW already have HSPA+ or it is still being worked?

    Dallas/Fort Worth is an HSPA+ market. It was actually one of the first couple to be lit, aside from Atlanta, Chicago, and parts of Florida. Tower backhaul is still being expanded though. HSPA+ puts a serious strain on backhaul, and that's why it's not living up to expectation yet.

    Confirmed it on a retail unit this morning... The Inspire and Atrix are shipping with APN settings that route through a proxy that causes upload speed caps. Unfortunately, until we can get an update out for the affected units, rooting is the only way to fix it. To fix the issue you have to root the phone and manually change the APN settings to bypass the proxy server.

    Edit: On the Inspire, you may not have to root. On the Atrix you do.
