[Help!!]I can't hook up to HSDPA with my Kaiser anymore....

Hey guys, My device is Kaiser(TyTNII) and AT&T is my operator.
I live in Philadelphia, US.
Before yesterday my TyTNII can access HSDPA (with "H" symbol on the top right) when I try to use internet.
However, I use Kaiser Tweak to change some setting of my device and suddenly my kaiser doesn't recognize HSDPA network anymore, I mean it will only show "3G" on the top right. I have checked all the settings and everything seems fine.
HSDPA function is checked and same as in the Kaiser Tweak.
Can someone help me out here?
Thanks.

i have the same problem, cant go into hsdpa or even 3g only edge. and it seems to have happened after using kaiser tweak also.

Got some help over in the Kaiser forum that helped me. Go to your comm manager then settings/phone/ then go to band and switch your network type to wcdma. after it updated the network i switched back to auto and it seems to be working so far for me. hope this helps you out, something you could try.

I seem to have the same issue but the above solution doesn't help. Whenever I set the phone to do HSDPA through Connections I loss all data connectivity, once I turn it off HSDPA I get 3G.
Is it possible for radio settings to survive a hard rest / ROM upgrade or is the HSDPA side of my Tilt broken :-(
Any insight or help would be real appreciated.
Several times I have gotten "Warning: Unable to change GSM/UMTS Band, Please try again later."

OK is it possible for this to be tower related? What I mean is I drove about 4 miles from my house, got a better signal and surfed the internet using HSDPA. Now I'm back home and HSDPA is chocking and giving me "unknown error 0x80072f78"
What He!!?

One note on my HSDPA trouble, it must some how be related to the one tower nearest my home. When I go anywhere outside a 5 miles radius (I live near the tower) everything works fine.
Here is the weird part, every where else the phone will switch from HSDPA to 3G to Edge and back no problem. Here in town it locks into HSDPA and refuses to switch to 3G or anything else. I don't know if it means anything but it seems to get an IP address I can ping but I don't get any DNS info!.
Now how can I convince AT&T that there's a problem when their support person denies there is any HSDPA services and I should only expect 3G?

3G mode not working sometimes

Have had this phone a coupla months, happy with it except the stupid GPS problem and some other connection problem.
When using wifi connection at home, if i stop browsing and close the screen for a few minutes and go back to surf internet, the wifi will stop working, turning wifi off and on again will make it work. Not too difficult but sometimes this feels sucks.
second problem is, occationally i will lose the "3G" or "H" sign on the top and cannot connect to internet using 3G data connection. i have no idea why this is happening. sometimes when i am out on street, try to check some information online, 3g is my only option and it really bothers me when it stops working. i'm using orange. all setting are as original.
Anyone knows how to solve these 2 problems?

the phone either works on
850/1900/2100
or
900/1900/2100
so depending on the model that you purchased
and where you live
also the cell phone provider that you are using
you might not get the full band usage of your phone
for example using the above models on a phone service that only uses
1700/1900/2100
then you are cripled
some telcos only use 1 band or 2 bands at most
1700 or 2100 for example

3g nodes and 2g bts wont give you the same area coverage, yes you will lose the H and drop down to 3g if your -db rating (signal is low) is at the highest limit for the cell and it deems you either need handing off to another site or you were one of the last ones to be allocated a slot and get kicked.
its how the cookie crumbles, no where will give you 100% coverage and if u are close to a small site thats overloaded with traffic you will always get crappy uplink and downlink...

I dont know where you are or what provider you use, but I have the same problem with my I900M on bell. it is apparently a widely known issue with Bell, and they associated my phone with the ongoing ticket incase it gets resolved they'll contact me.
Also, when I lose the 3g, ts a good chance my phone is going to lock up and need a battery pull to boot back up.
So Basically if I leave the house or wifi spot, I try not to show people my internet on my phone so it doesnt look like I'm carrying a brick in my pocket everywhere.

[Q] Omnia 7 data connection problem

Hi, since I got this phone and I've been having problem with the data connection, wifi is working fine, but 3G is not, it shows the 3G symbol but keep switching to H symbol and back again to 3G constantly, i never been able to surf the web or do anything online on 3g connection since i got it.
I tried putting in the setting from my provider and got the samsung network app thingy but nothing helped, even after updating to NoDo.
This is really bothering me i cant enjoy the phone when im outdoors, i switched back to my iPhone 3gs temporarily.
I really hope this can be solved.
I'm thinking if there is some way to make the phone only works on 3G and turn the H off.

H is for HSDPA and is far more faster than 3G. I reckon you run ADC on startup using samsung tools and hopefully the problems with connection will be resolved. Alternatively contact your sim provider for network configurations.

Here it also switches between H and 3G, or well it did on my other wp7 phone my (european) omnia uses 3g+. That's normal; the H mode probably eats your battery alive, and it only switches to it when your data connection is active (i.e. data is being transferred)
Your problem appears to be an Access Point problem, you can configure one yourself at the mobile connection settings page. (bottom). Check the web for the settings you'll need.
You see most phones are configured automatically by their providers, but the omnia probably isn't supported.
Hope this helps

the APN for China Unicon is "3gnet"
just add it your 3g connection will work.

serious issue on SGS-2 and 3g internet

i own a samsung galaxy s2 ordered from uk,
everything working fine except for this serious issue that i have been trying to resolve till now.
i have a monthly internet subscription from my carrier and it always been working fine on my iphone ( i mean here connecting through the 3g network ). but in the S2 .. i have to use Edge to be able to access the internet ( the mobile network mode must be set to GSM only ). whenever i switch the network mode to GSM\WCDMA auto , the 3g icon appears but when it tries to connect to internet, the phone automatically switch to Flight mode and i loose the network signal. and this happens all the time. till now i am only able to connect to the internet by switching the mobile network mode to GSM only which only uses Edge network .
i have tried every possible thing to resolve this issue but nothing worked for me. please help

What country are you in? What carrier are you on? What bands do they use?

location location location.
Where are you from?
And what frequency does operators in your region operate.

just curious, have you tried hard/factory reset?

i am from saudi arabia and i am using Mobily network.
mobily is using HSDPA network as well as Edge network.
i did a software reset and still the same issue.
phone information:
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD

crazy idea - is there any blocking going on in SA or with that carrier? Have you used another not carrier supplied smartphone successfully on that network?

I have been always using their 3g network on my iphone. And still there network only on edge connection on the s2. What i have noticed is that the saved apn sometimes shows up and sometimes disappears

Hi, very similar issue here.
For this four days since I have got my GS2 everything was just fine. The data connection and 3G speed was great. Yesterday, all of the sudden all got crappy. Could not display any web pages. It starting to display page but after few seconds pop-up window appear which say "Data connectivity problem. The server failed to communicate. Try again later"
Interesting that my gmail, market, xda app working fine as normal.
I'm in Ireland on O2 now.
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
Can someone help to solve the problem, please. Is it possible that something with the hardware is wrong? Broken?
I'll perform the factory reset and will let you know.

i just managed to flash my device with the latest EXE1 dated May 3.
and i am still facing the exact same problem.

Maybe we should ask for replacement...

I have same issue, and for Ihrrob, your other application are working fine because what i noticed on my mobile that 3G & 2G connection is there but not permenant that's why WIFI hotspot always disconnect and VOIP applications are not working.

You are right the 3G/2G connection is there but not permanent.
If I press the Internet icon the home page, which is 'Google' appears (sometimes) immediately. I think this is because the page is very light. If I try to open a regular page it loads 1/3 of the content or nothing.

i just hope it is a software bug not a hardware problem

Type on the dialpad *#*#4636#*#* and force the phone to HSDPA only on the dropdown menu. This is a hidden menu on the phone.

Isn't this carrier related?

Unfortunately not.
I have spoke to the rep in the store. They reset all settings for me but it didn't help.
Just to double check if he wasn't wrong I've put the sim card in to my N900 and all data worked fine.
Bad, bad...

I'm on Mobily network in Riyadh, and 2G/3G is working fine for me. I stay on 2G most of the time to save battery, but have tested 3G and got around 3mbps.
I have the same Baseband, Kernel and Build number (rooted)
Are you using "Market Enabeler"? It can change your APN settings, and you need to restore the provider setting.

just rooted my device.
still same weird issue.
issue again: simply whenever my device tries to connect to H+ , the device automatically enters flight mode and automatically disable flight mode so that the signal bars come back without H+ and when i check back the saved APN i see nothing there ( thought i was there before ). and this strange behavior disappears when i switch the mode from GSM/WCDMA auto TO GSM only .. after i do this the device connects regularly to Edge network and i can browse the net.
so basicaly for me i will be only able to use the device on Edge instead of HSDPA or 3G.
im really hoping for help from here because i don't think i will find any help outside of this expert community.
regards

try to make it on obligatory 3G (WCDMA only) and check if the problem still there ..

still same problem juffo
i have noticed that another post are poping up talking about almost the same issure.
i hope a new firmware will fix this

Wow, this is ridiculous and why is this happening?

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?

maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.

When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?

Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available
Sent from my GT-i9100 equipped with Grenade Launcher and Remote Explosives

Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!

:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location

I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".

I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).

If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.
