Method for blazing Speeds on ATT using Wimax.

---

As most using GS2 on Att the data speeds are poor.
I have mine on Att $50 prepaid unlimited all, using an infuse Imei.
Data speeds are still poor (avg 12-1500kbps).
ANY phone on Att "4G" performs poorly.
So, what I did (initially as a temporary measure) was get a Sprint MiFi portable hotspot ($35mo), carry with me and run off their 4G. (My work has me on the move around the chicago area...it's worth it).
I can tell you, data absolutely FLIES...(significantly better than the Evo 4g btw, as your at the mercy of tower positioning. The Evo on the Mifi performs way better also).
In the 10days I've had it, I've NEVER gone to 3G.
I'm considering just sticking with this arrangement when SGS2 breaks here if the phone's are dumbed down in any way. Good thing is the data reports to Att are virtually Zero on my dumbphone plan at 6-8M's/mo.....as I have unlimited data on Sprint.
So yeah its $85mo total for me.
SO, for those who really prioritize network speed (and why tether this brilliant device to a 3rd rate network), you might consider trying it for 30days. Don't need a current Sprint account.
Makes unlimited surfing and tethering movies etc fun again!
(suggestion tho if you do: have an extra phone and MiFi battery, and wall charger!).

I agree that the 4G speeds are not much faster than good 3G, no matter which settings are tried. Glad to know Sprint is fast, the competition is sure to cause AT&T to increase their speeds to keep up.

That being said, you may want to rename this thread. I was expecting some new method to improve AT&T speeds when I clicked it. Something like "AT&T is hopelessly slow, tether with Sprint instead" would make more sense.

For me, I can't be bothered to carry a MiFi with me at all times and pay another company money each month. I'll just do the best I can with AT&T and hope they improve the HSPA+ speeds in my area. I get between 1 and 2.5 mbps just about anywhere so its not unbearable. The real killer is the slowness to switch from 3G to H+ every time I try to use the data connection...

Ah, your right about title.
I guess it's method to obtain fast speeds while on Att!

It's sounds like something's wrong with your settings or SIM. I live in a 3G area and pull between 2-3MB down. When I'm traveling in a HSPA+ area I get between 4-8MB down. I'm on a post-paid data for non-Smartphones plan. I actually do the opposite of the OP. I use my SGS2 to tether my tablet and download and watch Hulu with no stuttering.

I got similar speeds on my old Captivate (although it was HSPA, not HSPA+). Friends of mine with the Inspire get the same speeds as well. I think its the area. I live in Central New Jersey and according to PCMag's mobile network speed test, this area is about the worst there is for AT&T speeds:

What area's are you getting between 4-8 in? Have you ever tried in New Jersey?

I've got 2-4kbps.....but it's rare. It's usually 12-15 give or take. Also, ping time on Att seems really slow, usually double the time of Evo.
I've tried new sim twice.
2nd time went to an Att guy I know personally, showed him the SGS2 (normally I wouldn't cause they'd take it to the computer and not allow it on dumbphone plan)....he made some adjustment in the system for me gave me a new sim card....and results were the same.
Speedtest doesn't reflect real world results anyway.
Take a site....say crackberry.com....at its 4bar best Att will download the whole site in 35-40 sec. MiFi is consistently will do it at 15sec.
It's always about 3 times faster. For a guy who needs data on the go, that's big.

I'm in Los Angeles and my speeds are generally between 5-8MB/down. Recent trip to NYC yielded similar numbers.
