When browsing or tethering, unless the connection switches to H it is basically useless - won't even load google.com. I am aware of the speed differences between 3g and HSPA but is this normal?
I'm running CM7 nightly.

Yes.
It's not useless, it's just slow - and having HSPA, your basis for comparison is subjective and flawed. Measurement with SpeedTest would tell you the exact differences in numbers - but in user experience, the difference seems way more than the numbers show.
Moreover, when your phone attempts to connect, if the mobile network stays on 3G - it can mean that it has no reliable connection.
for me 3G=HSPA
it says 3G until im pulling data and then it switches to HSPA, ive never pulled data while on 3G

3G is UMTS. HSPA is like 3.5G. They didn't call it 4G because it was more of an additional way to provide a slightly better 3G.

Title says it all. When i have NO HSPDA I become screwed and I have to revert to EDGE otherwise I have no data connection. I haven't tried it out of town yet, but it's ridiculous. It says I'm on 3g, but then switches when I start a speedtest. Is that just because I'm always in HSPDA? Any ideas?
I'm on the Desire ROM. I don't think it's the rom though, because this happened on Cyanogen.
HSDPA is only on when necessary, when it isn't, your on 3G. You're in an HSDPA area, so when you use data your carrier bumps you up to HSDPA.

Assuming you're in the U.S. and on T-Mobile, this thread covers your issue:
3G --> H Data problems
Cheers,

Ahh much thanks. So in theory if I leave the HSPDA area my 3g will work because it isn't trying to switch?

If you leave an HSPDA area and only UMTS (3G) & EDGE are available, then in theory, yes. The data will transfer over 3G or EDGE. It's normal for the N1 to "idle" with the "3G" icon, but when you're actually doing data transfer, it'll switch to "H" if it's available.
In other words... nothing is broken. =)
Most people are confused by the "H" because on the *Stock* ROM, the "3G" icon doesn't differentiate between "UMTS/3G" and "HSPDA"... It'll always display 3G with either technology. The *Custom* ROM's differentiate which technology the handset is talking with the tower in regards to HSPDA and UMTS.

At the top were you see signal strength I nebver seem to have 3G enabled and internet seems to be slugish I sometimes have the Letters G,H,U I don't know what these mean is there a way I can have 3G all the time?
Thanks. Stock Rom!
as far as i know h and u stand for 3g not sure tho

I don't think it does its so slow. I want to know how to enable 3G permanently.
were you getting faster 3g on other phones? and i think there is a cab but u may have to search for that
As far as I know (In my area) H is for HSDPA, which is an enhanced form of 3G. So it seems that you are getting 3G data... While G stands for GPRS, which is 2G.
No idea what the U would stand for though.
Also, if you have 3G enabled to auto-connect (I presume it is, if it's switching between the connections,) then your phone should just pick up a 3G signal whenever it can find it. If 3G is patchy in your area, you won't be able to get it all the time.

Right I see when I'm on HSDPA it is still very sluggish until I seem to hit 3G and its like wi-fi, so my 3G is already connected just needs a place with good signal when I'm on way to college on the bus I seem so find a good area with 3G. Thanks for your help.
H = 3G
G = 1G (G is much much slower than E=Edge=2G)
If you want to have 3G only enabled go to Settings>Wireless Controlls>Phone>Band>WCDMA (Note that if you're in an area with no 3g, you will have zero signal and the phone will not switch to edge or gprs).
In the right order:
G=1G: 'Global System for Mobile communication', or GSM, basic mobile network.. can be used only for SMS and Phone calls
E=2G: EDGE (or 'Enhanced Data Rates for GSM Evolution'), basicly GSM and GPRS (data transfer) combines..it allowes for speeds over the mobile network up to 9 600 bit/s
U=3G: 'Universal Mobile Telecommunications System', or 'UMTS' up to 2 Mbit/s data transfer on stationary devices and up to 384 kbit/s on mobile devices. About 40 times faster than GSM. This enables you to transfer data, such as images and be able to transfer data during a phonecall.. like sending a MMS or using Video Calls.
H=3G: 'High Speed Downlink Packet Access', or HSDPA, it allows for speeds up to 14,4 Mb/s though it is normally (at least in scandinavia) offered commercially in lower speeds, up to 7,2 Mb/s
Note: Because the most operators use high frequency to transmit '3G' signals, wich can cause your signal to be lower if you're inside (house or whatever, not outside), some operators though, transmit on a lower frequency, though then it's called CMDA, wich is also a form of '3G'
Had the same problem with a Telstra HD2 on Optus. Here's what you need to do. Settings -> Wireless controls -> phone -> Band -> Select auto for both. That should do it.
Im coming from a couple HD2's and Vibrants and from my understanding, HSDPA is only 3.5G. Well, I only see HSDPA connection on my phone, and not a HSPA+ signal.
So am I even getting 4G?
You wont really see anything different to distinguish between the 2 besides running a speed test, Im on cm7 so I either see an "H" which is hsdpa or hspa+ but only a speed test over 3.5 will let me know for sure if I'm on the Hspa+ then theres the 3g icon which is usually umts but can be hspa, like I said just use the speed test ap thats the only way I ever know
also the highest Ive ever seen my 4G in los angeles is like 7.5mb on the normal it hovers around 4mb which never leaves me quite positive im on hspa+ because my wifes 3g Nexus S usually pulls down around 3.8
are you using T-Mobile or simple. I am having an issue as well but the plus sign is a huge difference.
i dont even know if you will ever see the HSDPA+! the way to check is go to settings>about phone>network> now here is where it gets tricky. where is says Mobile network type: it will tell you when you are on GPRS and EDGE! when my phone is on 3G is says UMTS, when it is in 4G, is says HSDPA. this is based on me doing speed tests while phone was on said network types. also i use a widget called "mobile signal widget". as you know the status bar never tells you the difference if you are on 3G or 4G, but the widget does! when the widget says 3G on it, when i flip to settings it says UMTS. when the widget says H on it, when i flip to the settings and it says HSDPA.
Even while tethering, my N1 (CM7 nightly, 5.08 korean radio, T-Mobile USA) jumps back and forth between H and 3g. I understand that HSPA is supposed to be a 'temporary link' according to
http://forum.xda-developers.com/showthread.php?p=12159174#post12159174
1. Is there a way to force the N1 to only use HSPA during tethering?
2. After about 30-40 minutes of tethering (lots of HSPA usage), my phone drops from H to 3g and remains there for a good 30+ minutes. Then it comes back to HSPA (tried rebooting, tethering/untethering, etc..) - is this something limited by T-Mobile? It always happens after about the same usage..
Thanks!

tmobile network seems to configure their phone differently than ATT. tmobile, the phone will sit on 3G until data transfer takes place, where it jumps to HSDPA to transmit, then goes back to 3G. so i think your phone is working normal. test it out and post the results.
there was an app before called Network that let you set it to whatever you wanted
i cant find it on the market anymore tho
I'm pretty sure it's the networks themselves that control this.

I agree. My experience with T-mo is that it sits on 3G (or UMTS, according to the status screen) until a data transfer needs to take place, then it turns to H (HSDPA) and transmits and recieves data.
I have also noticed that its because of this that it sometimes 'hangs' with the 3G up arrow on.
Have searched the entire forum for this to no avail. I want to disable HSDPA and only enable 3G. This was a straightforward process on my SGS. Assistance appreciated.

HSDPA is the only 3G standard that the phone supports, as far as I understand. So as far as the Desire HD goes, they're the same thing.
I am on t-mobile in th UK. My dhd switches between showing a G or H on the top line. If I go into settings, about phone, network, mobile network type. It shows either gprs, udms or hsdpa depending on signal type available. The phone supports edge too and can show an E on the too line but T-Mobile uk don't appear to support this.
Not sure how you could limit it but t-mobile have done this for some,contracts as reports elsewhere of download speeds capped at 384kbs I.e. max rate for 3G rather than the 2mbs+ I have seen on mine. Seems to be,contracts bought through resellers that don't include data and they use the free booster to provide the data element.
Hth
I am on T-Mob in the UK too. I get either G (GPRS) 3g (3g) or H (HSDPA) not seen an E yet and I have had it since October.
Mine switched between 3G and H on its own accord, there is no toggle that I know, think it depends on where you are and the mast you are connected to at the time?

I get E every now and then but mostly when my phone switches from orange to the T-Mobile network.

It depends on where you are and the signal strength your getting, why you would want to disable HSDPA is beyond me, it is the fastest you can get on your desire hd, E being the slowest (edge) then G, 3G, then H.
Why would you want to make your device slower?
Very weird, but anyway, as far as i know you can only toggle between 2g and 3g which will incorporate HSDPA as well.
Hope this helps.

HSDPA consumes more battery. My SGS used to support Edge, 3G and HSDPA too with an option to disable HSDPA and and allow 3G and Edge only.
Thanks for all your replies guys.

Download Advanced Settings app, go into phone info and there are some options there. Can't remember which is which though, there is a thread in here somewhere about the settings

E is much slower than 3G

Who was telling otherwise?
For Using only 3G or HSPA
Settings->Wireless &Networks->Mobile Networks->Network Mode->select WCDMA only.
Here according to your preference change between UTMS(or WCDMA) or GSM(2G).
Also to clarify speeds
G<E<3G<H.
