What value to you see under "WIMAX_Idle_Sleep(s)? ?
Thanks!
WiMAX_Idle_Sleep(s)

Ditto. 10.
Thanks.
And you start 4G, simply leave the 4G connection on without doing anything on your device (but keep the screen on).
Let me know if after about 1-3 minutes you see the 4G connection drops and reconnects or not.
Changing the value in the above post to 300 fixed the reconnection problem for me, but i wonder if this problem was happening just in my area with the above value or not.

Symptoms
- You cannot maintain a constant data connection. The connection is often lost or dropped.
- HD2 reception indicator dances between G to 3G to H despite showing good reception, and user remaining stationary.
Counter measures - No cabs or registry tweaks needed.
Presented in the order I would try them. If the lower number levels don't work, then move up a level. These are offerred as advice from a UK based HD2 user, though may work for you elsewhere.
LEVEL 1
- Go to Comm Manager > Wireless Controls
- Turn the Data connection Off then On again.
This will usually get you back and running again faster than waiting for the HD2 to sort itself out.
LEVEL 2
- Go to Settings > All Settings > Connections > Advanced Network
- Disable HSDPA/HSUPA
This will stop your phone attempting to use '3.5G' and will mean that you only use 3G.
Remember to re-enable HSDPA/HSUPA when you are in an area with better reception.
LEVEL 3
- Go to Settings > Wireless Controls > Phone - Change phone settings
- Move down to Other Options > Band - Change baseband
- Change Network Type from Auto to GSM
- Change Band frequency from Auto to either GSM (900+1800)+UMTS or GSM (1900+850) . To make the decision, you need to know the GSM frequency your operator uses. If you don't know, you can just try both of the GSM options and see which works. No damage will be done by using the wrong frequency first time, and you can change back.
This will disable 3G and force your phone to use 2G. Most operators have decent 2G networks, so you shouldn't have the disconnects anymore, but you will have slower than 3G potential speeds.
Remember to change your phone back to Auto for both Network Type and Band Frequency when you are in an area with better reception.
Thanks for the heads up... will have to try some of these. I find it most annoying at times...!
Thanks for the advice, I do find those issues annoying. What are the benefits of using 3.5G? If they're aren't any major advantages and turning this off helps then I may as well leave it off.

The problem with this is that it b*llockses up your push email settings, if you use the phone to get email from an Exchange server. The better approach (assuming standard configuration) is to press and hold the power/end-call hard-button. That brings up a menu of four choices. The last of those is "terminate data connection". Click it. Anything the phone does which requires the data connection after that will automatically reactivate it.
3G 2100
These tricks may solve the issue for many but not for me because I'm in a 3G 2100 only network so I cannot switch to GSM. I will try to disable HSDPA/HSUPA to see if that works though.
The weird thing is that the issue occurs almost exclusively when I'm logged on an IM client and the phone stays in sleep mode a few minutes (say 15 min or so). After I wake up the phone the signal seems ok but the data connection is lost (IM, browsing, mail, weather update, etc.). It doesn't happen every time but very often, several times a day.
If I don't log on any instant messenger app the data connection is stable, especially with the new 1.66 ROM (I tried both Duttty's custom and official). In this case I lose data connection very rarely, in fact I din't even remember the last time I did.
Can anybody provide an explanation for this, what is happening with the connection between the IM server and the phone during sleep?

If your network supports it, you should have higher potential data upload and download speeds through using 3.5G (HSDPA/HSUPA).
In reality and every day use, on many networks you probably wouldn't notice the difference between 3G and 3.5G.
I'm on Virgin Mobile, which piggybacks on T-Mobile's network here in the UK. My speedtests in central London, show virtually no difference between me using 2G, 3G and 3.5G!!!! Which is ridiculous. The main difference I get as a HD2 user is much more stable data connection on 2G vs 3G/3.5G.
I use a lot of data for content streaming. At work I have low signal (1 bar) and sometimes the networks changes to 1x Data. (Yes, I know the epic doesn’t indicate it, but I can tell by the reduced bandwidth and about 3 second drop of all data when the switch is made.
I’ve noticed that if someone calls while on 1x data, the calls go straight to voicemail, it does not ring at all.
Is there a way to set the phone to 3G data only? And if there is no 3G available, drop the data connection?
Short recap: I Want 3G Data only. If not available, no data connection at all. Wi-Fi is not an option at my office nor is 4G.
Thanks!
You're going to need your 6 digit MSL (master subsidy lock) code.
Go to phone, ##DEBUG# (##33284#), enter MSL, scroll down to Others, HDR/1X Selection, EVDO Only Mode, Ok.

is this setting like the old school days 6700/6800, where as if you set/force your phone to "EVDO Only Mode", you will lose Text/Voice since those only work on 1x.
Can't really tell, never left my Epic on EVDO only mode (don't need/want to). The Mogul (6800) is one phone i really don't want to remember.
Doesn't hurt to be a guinea pig though in this particular case..
lol...yea those setting were nice if the phone would bonce back and forth 1x/EVDO and you needed EV to stick and did not care about phone calls or also if you were downloading a big file and did not want to be disconnected by a call 8)
Well after many searches and a lot of trial and error, I think ive finally solved my problem of dropped/no phone signal for NAND builds, which in turn has also made my battery life way better since the phone is no longer constantly searching for signal Basically its 4 steps, ive tried each individually with no changes but for some reason when applied all together it works wonders. They are as follows:
1: dial *#*#4636#*#* and go to phone information and choose 'gsm auto PRL'
2: go to settings>mobile networks and check 'use only 2g networks'
3: go to settings>wireless networks>wifi>advanced and change wifi sleep policy to 'never'
4: go to app store and download "wifi keep alive" (free). choose wifi behavior 'always on' and advanced options 'enable workaround 2'
using these 4 steps i reduced my time without signal from 74% to 12% in 16 hours, and im getting 4-5 green bars all the time, at home and work hope this helps
I'm not an expert, but doesn't that mean you are stuck in 2G-Mode for Data Transfer? I believe 3G if available would be faster..... or am i wrong?

yeah, it stays in 2g for data but for me its an acceptable trade off to actually be able to recieve calls. plus you can always switch 3g back on if you plan on doing something that uses a lot of data and switch it back off when youre done
damm i was excited until i saw that you have to disable 3G
Is this a common problem?
or... you could just go to settings/wireless&networks/mobile networks and change the network mode to gsm only (which is 2g) so, same thing.. and you know what? i still have signal issues, just not as bad..

yea i think that option is only on Desire or froyo builds, on all of the GB's ive used it says 2G. i suppose its not gonna work for everyone, it probably still depends on your coverage area, but it definately helped me A LOT. ive been using these settings for the past 3 days and my time without signal has dropped down to 0-5% from the 55-75% it was before, and im no longer missing calls
very useful tips
I ticked the "Use 2G only" checkbox in my wireless settings and all connection problems seem to be gone! (for now)... My data connection used to be terrible... voice connection shaky.
Thanks a lot!
Hi, does anyone know why on earth did HTC disable the 3G Switch for HTC Surround?? I have this phone, updated to Mango and the 3G Switch is missing from the Network Settings. I cannot understand this stupid idea of not letting the user decide what band to use his phone on.
RE: Solved
I have solved this.
This is available for every HTC Device which does not have the 3G Switch available:
Enter the Field Test Menu by dialing ##3282#, on the lower right side there are three dots: ... , enter that menu and there you can choose the band to work on: Automatic, 2G only, 3G only.
Sounds like a solution, but each time I change the setting from 3G to 2G or Automatic, and then go back into settings, it reverts back to 3G only. And the 3G icon remains at the top of the screen. So is your experience different. Been trying to disable 3G since December.

Do not set to auto,
Set it only to 2G, go back in the field test main menu with the back arrow <-, and then again in the ... menu, 2g should be still selected, and then <- twice to exit.

Gave it another try, but not so sure.
Went in to menu, set to 2G and then back arrow <-. Went back in ... and 2G was still selected, but after exiting <- <-, and going back in, 3G is selected again. Also my phone still shows 3G at the top of the screen, but I will admit that the signal strength appears to maybe be 1 bar higher. So, am I on 2G although the 3G icon still shows?
Guess I will know tomorrow after a full day of use hopefully at 2G, with reduced battery drain. I have a great WiFi signal at home and at work, so basically 90% of my day. The only thing data does is load email in the background and the occasional need for a connection if I stop somewhere on the way home. My 3G signal is typically 1 to 3 bars, averaging 2. And almost never higher than 3.
I have an unlimited data plan, but my WiFi speeds are generally 3 to 4 times better, and my experience has show very little difference in battery drain with WiFi on/off. No idea why AT&T would prevent me from using 2G, especially with Unlimited. iPhone users should be thanking me for the extra bandwidth I am offering.
Btw, I will absolutely NOT purchase a new phone with 4G/LTE whatever, unless I can turn it off.
I'm just curious if there is any kind of registry editing or something like that could disable my Samsung Focus from dropping down to GPRS signal? I'm not looking to disable the internet signal entirely, I'm only looking to either drastically lower the priority of GPRS or disable it so that I only connect to EDGE and above. My phone connects to edge just fine at about 3 bars of signal and works great, but as soon as I get 4-5 bars of signal it automatically drops to GPRS, which makes no sense to me, I would rather have 3 bars of signal and use EDGE service than to get a better signal on a drastically slower internet speed.
Open Dialer and type ##3282#
(you'll see "field test"... look lower right on the screen for "...")
select settings and limit "Network type" to "3G only".
There's some other stuff you can do, as well. If you don't see the drop down menu in settings/cellular: "Highest connection speed", you need to add some registry keys.
You can limit down the connectivity level (depends on network), see this thread for registry tweaks.
1st, you need to enable the 3G toggle:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Connectivity\CellularCPL]
"Show3GToggle"=dword:1
Then, if you still don't see the drop down menu in settings/cellular:
"Highest connection speed"
add this too:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Connectivity\CellularCPL]
"ShowConnectionSpeedOption"=dword:1
Then, you should see "Highest connection speed" drop down menu.

I actually have all these options, seeing as they come with the custom rom's I've been using. Right now I am currently using Jaxbot's 7.8 Rom. The only thing I wasn't aware of was the ##3282# in the dialer to set the network type. However, seeing as I'm in an area where TMobile hasn't deployed 3G+ on their PCS1900 frequency, 2G is my only option, If I set it to 3G on the field test like you suggested, the phone completely loses signal. I'll try and simply my situation for you to see if you or anyone else can possibly find a solution to it.
I can be sitting at my desk, and have 4-5 bars, and while my icon says "E" for Edge, if I test it, I will only get a maximum of 55 kilobits per second. However, If I move my phone slightly over to an area that I know it drops to 3 bars, run the test again, I'll get 200-250 kilobits per second. (Which I believe is the maximum for EDGE and generally what I'm trying to STAY in until they deploy the 3G+ in my area, I'm actively following airportal.de so I can be aware if it's near me or not)
Now this is not ALWAYS the case, because there are some instances where I can have the 3 bar signal and have the E symbol, and as soon as I do something network intensive, like running a bandwidth test or attempting to stream something from last.fm or what not, It will jump up to a 4 bar signal strength quickly and change the E to a G, but only momentarily, because the G will then go back to E, though the speeds never change.
Essentially it's almost as though my phone is choosing to revert back to GPRS over EDGE just because the signal strength is better, which I could care less about, I would rather my phone just stay in EDGE and not default back to GPRS over the better signal strength.
