Hey i have a 32B UK Vodafone Magic running Cyanogens 4.0.4 stable rom and have had the magic for about a month now.
For some reason my phone randomly loses connection - both 3G and 2G, the drop down notification will just say "No Service" and will only usually restore if i turn on- and off airplane mode.
There are also often times where ill be browsing the internet or the market and while it'll tell me i have 3G/2G, it wont actually "connect" and download/upload data e.g. the market will often tell me it has no connection and web pages will randomly not load, getting the "webpage cannot be found"-like error for no reason. wouldnt be such a bother but it seems to be a daily occurance that spoils an otherwise amazing device.
Is this a common problem? does anyone know how i can solve this if a solution is available (i thoguht it may be to upgrade the radio but i dont know how and ive heard its possible "brick-territory")
hope you guys can help
Hi there, this is getting to be a well known issue on the Vodafone technical forums.
http://forum.vodafone.co.uk/index.php?showtopic=25796&st=0&start=0
have you read this and posted there?
Would be good from some feedback on here too from "the experts"
I'm having the same problems with my phone: http://forum.xda-developers.com/showthread.php?t=556843
So far, turning off 3G has stopped it, but that's not really an acceptable long-term solution...
as you say, disabling 3g is not a solution to the problem encountered considering the device and its expected use, its connectivity should at least e stable.
i did not know about the thread on the vodafone forum and read through all of the posts, there didnt seem to be any strict correlation between the other guys devices and the problem itself, some had diff radios, some likely had flashed roms (but theyre not exactly going to mention that on a voda forum).
thanks for the help regardless, i think im going to do some testing of custom ROMs and some of the radios/SPLs to see if one of them may fix it. though again i dont think its a probplem that can be fixed from a ROM/android update alone
I've been having this issue too, i've gone through multiple roms in search of a fix, none of them solved it though. . .
Are you guys having any other issues coupled with this? My phone also won't autosync email anymore. No notifications, then i'll check manually it will find a slew of emails from earlier in the day. It's set to check every 5 minutes, but alas.
same here with a vodafone magic. I have this prob not only with 3g even with wifi. Turning wifi/3g on/off solves this issue. Its annoying though...
Hi Guys,
I've been having some problems with a very short battery life over the past few weeks. I've disabled HSDPA/HSUPA and am experiencing slightly better performance. While fiddling around with the settings, I noticed the above options, CSD Line type etc...and was wondering what they were all about and if the optimum settings are already set up on the HD2? I'm on an unlimited data plan with T-Mobile UK and I'm assuming that the phone has been set up a specific way by the network and wouldn't want to change anything that might negatively effect what is, so far, an excellent phone but I'm just curious.
It's nothing vital and I won't be fiddling with anything but I have done some research out of and it all seems to be related to data communication/speed. Could any of you guys shed some more light on this as a lot of the stuff I'm reading is a little over my head!! I would be interested to know if there was anything in those settings that I might be unaware of that could make my phone supersonic, hahaha.... Any info on these settings would be appreciated.
Thanks
Shameless bump.
The reason for this thread is to request that Data / Connection Controllers be removed from cooked ROMs and leave it up to the individual to choose / install which one they use. If possible, make them removable.
Over the last couple of weeks, new ROMs have these utilities built in and what that meant for me is intermittent data connection. I have cell signal but no data connectivity. The worst part about it is that you don't know when it happens. I've flashed a combination of Radios & ROMs and have the same result. This leaves me to believe that it must be something in my area (Tampa, FL-Tmobile). ROMs without these utilities work fine for me.
Just last night, I was discussing this with a couple of my friends who flash their HD2's & are experiencing the same thing.
If you're having the same or similar issues, please post your experience along with your area and carrier.
By no means did I wish to blame any Chef and/or Roms, I appreciate the ROMs because I'm a flash-o-holic ... so keep pumping them out.
Chefs, if you have any suggestions....please jump in.
This possibly needs to be in the dev section but I will start here.
First off this is not a complaint. What I initially want to do is get an understanding (Technical) of the issues around the PPP dropouts and locks ups.
From where I sit this is the only outstanding issue around the current android builds. Simply the phone rocks on SD card and is ultra stable and fun.
I have noticed various wiki'sstate that internet access is complete however obviously not.
There are a number of issues such as
1: Network dropout. Data connectivity will stop responding. Restart of the radio or mobile data needed
2: Network freeze. Android restart as the radio will not turnoff.
3: console level networking not avail. Eg ping etc simply does not work. DNS does not resolve and ping cannot find a route. Std Android this works fine.
4: Related issues. GPS-A data not downloadable. Only via application layer tool.
Is PPP the default connection type on factory android builds?
What is the difference between the HD2 in dev and a std android with the implementation of the data connection.
How can I help. I have over 20 years in IT and have a thorough understanding of TCP IP layers and routing. I have reasonable understanding of Linux and the kernel IP stack but zero understanding of the android kernel or application layer.
I also have dollars to contribute.
Update:
Currently I am trying all four with isome improvements
1: Updated the Ril WRapper with no luck.
http://forum.xda-developers.com/showthread.php?t=794309
2: Change the phones default connection to GSM PL.
Change the setting found in the menu phone info when you "call" *#*#4636#*#*. There is a option to choose your preferred network. Set to GSM auto (PRL)
3: Update DNS settings.
http://forum.xda-developers.com/showthread.php?t=812930
4: Ensure the correct APN's are being used.
This is no internet versus unstable Internet.
Note. Currently trying all four and things are improving. Had my first dropout after 36 hours versus 2 per day. It happened whilst using the GPS and making a call which always tend to be a stresser anyway. Will try to keep this thread updated.
This thread also has a number of updates http://forum.xda-developers.com/showthread.php?t=813148
I am running a stock WinMo Rom (Latest European release 3.14 I believe). 2.15 radio on a Telstra Network in Australia. My phone is a T8585. Also running [19.10.10]|<<Mdeejay FroYo Sense Series>>|2.25.771.1| cos I like the transparent titlebars
Now I have been running all 4 of the above for around a week now and have to say there is a def improvement. Where it was common to get multiple disconnects per day I have only had 3 in the last week. Mainly when I use the GPS.
I am still searching and have yet to find a 100% fix the stability is now at a point of reasonable reliable. Also noted that the Devs are still hard at work on this.
Update 31-10-2010
A good test is to open google maps while driving. Its about the only time I get a drop out now.
The GPS kicking in always stresses the radio and that combined with the handover of cell sites is a great deal breaker.
This also seems to be consist with my suspicions around the poor handling of corrupt connections.
Eg the system on fresh boot only has a table for handling 50 connections line. This ensures it can handle multiple simultaneous connections as well as background coms.
Now when a connection is damaged or locked normally it should timeout and/or then be deleted from the table. My suspicions is that this is not happening and all the avail connection handling are slowly filling up until there are now free. Frozen this is why it seems to be very unlikely for a freeze to occur straight after a restart but more likely after a day. Also dependent on stress environments. Homes with lots of RF noise, Long way from cell towers, driving, lots of gps use, Wifi cut over.

Thanks for the response.
I was not looking for work around but more technical information to try and identify where the issue lies. curious to see if ppp is the default and if the ppp implementation should work or is it still a hack/work around.
The steps I have tried are
1: Updated the Ril WRapper with no luck. No improvement
2: Change the phones default connection to GSM PL. No improvement
3: Update DNS settings. Still testing however does not resolve console level network issues and unlikely related to ppp freeze. No logic?
4: Ensure the correct APN's are being used. No improvement
Note. Currently trying all three
This is also separate to a lot of people issues around APN's. From the application layer internet works fine except for the freeze.
I believe rmnet is android's default connection and ppp is winmo's. I think dft reengineered ppp for Android. Remember seeing it some where when ppp first started to appear. Of course this is how I remember it and my life is hectic so it might be the opposite.

So I understand that one of the issues with RMNET was dropped packets. Was this due to it not being correctly engineered/implemented or just a nature of the beast?
Also with the issues everyone is having why are we not continuing to investigate RMNET as at least this was initially more stable and more of a native option.

That is because it isn't implemented correctly. The radio receiver in our phones was made for PPP, not for RMNET. Latter is standard in native android devices. And there it works very fast and stable. So the devs had to implement PPP in android, which isn't proper working. But they're working on it to improve the stability, I'm pretty sure 'bout that. At least it does work and I had never problems with loosing my connection and bad speeds.
Edit: Those are the known steps to get it at least halfways stable working.
Cheers
Okay.
Did some more playing.
Both RMNET and PPP allow pinging from the console. Just had to enable SU first.
Thanks everyone for your info. Will try my best to be patient.

But did you also have a delay till it worked? It took me about 20 seconds before any reply came up. And does your ping test work if you try it in the hidden menu when you "call" *#*#4636#*#*?
Aye.
There was a delay and the hidden menu ping does not work either.
Still needs work.

Right.
Have you seen this thread? It might be a possible solution.
Some people have reported that it works. But I had no time to test it. Had to move servers
That is fix number 3. Update DNS. Testing now. Only been 24 hours however no drops.
Seems strange thou. Hard to imagine it is a DNS issue.
On a side note. Does anyone know what changes to the Rom are needed when installing an RMNET kernel?
Eg If I took the latest MDeejay rom and changed the kernel?
Update
Update on first post.
Def improvements to be found. DNS seems to be the biggest improvement for me but also running all 4 at once.

No one who knows cares enough to answer.
As far as I can tell, no 'modern' build uses an rmnet kernel anymore, because apparently the chefs either don't care about data reception, or don't think that there is a problem because they don't leave a build on long enough for it to start developing problems.

any build that says it uses michyprima r11 is still rmnet based. I don't think the nexus one-based kernels worked with ppp at all.
on another note, I was getting loads of Network Freezes (where flicking airplane mode wouldn't reset the data connection) since last week despite not fundamentally changing anything in my Android setup (see sig). However been doing some research around xda yesterday and may have found something else that's improved my ppp connection stability (so far) and resolved my constant network freeze issue... will update when I've tested this for a few more days.
Some improvment?
APNs are correct, Did the RIL_WRAPPER with no significant improvment. This morning I changed to GSM PRL and noticed an improvment.
Before the GSM PRL, I had many PPP drops, especially when streaming large amounts of data. After the GSM PRL update, I did try streaming youtube, Last.FM, slingpalyer together and NetTest, concurrently, everything is working with no PPP drop.
This is not enough to reach a conclusion, but nevertheless, I never could have done it before
Have a look here.
Stock rom 1.48 WWE, radio 2.15.50 and Froyostone 3.2
Thanks for the support!
BTW: How can I obtain the DNS information for my mobile carrier?
Just report.
I didn't believe change dns will work.
But after I change dns, the data suddenly work ( no need to restart!).
So I think it have something relate to dns.
Same thing. Updating the DNS in the build.pro file seems to have the greatest benefit.
I have a suspicion that the issues are caused with the network driver not flushing dead connections. Eg outgoing requests that to not get a reply. Ideally they should be flushed other wise the connection cache will fill until it can no longer take more connections. Symptom dead/frozen internet
All the symptoms seem to relate to this sort of issue
Things like ppp drop out more likely when on the move (More dropped packets). GPS and wifi but back. etc.
@Dusty_Nz,
Thanks for your help, this is a great thread and its certainly appreciated (the devs are busy enough as it is, xda member contributions are a great help).
As it was asked a few posts up, how do I obtain the DNS settings for my carrier? I am using TMobile US and I'd like to test your observations.
Thanks!

Hello. First, great forum- I can feel the love, as well as the collective genius at work here. It's refreshing to find a forum where people actually know their sh*t on a real, technologically advanced level. It's relieving as well, considering the headache that my new G2 is causing... as follows:
This is a Sprint device and I am still within the time frame to return if a resolution is not found.
Issue:
1.) While wi-fi remains connected (doesn't drop), it is terribly slow, averaging .8 - 3 mbps. Whereas, other Samsung android devices are averaging 15-20 mbps. Internet is cable, and I have reset the modem without experiencing any performance increase. (technicolor TC8305C, bgn)
2.) 4g is no better, averaging a mind boggling .5 mbps. (Don't even get me started on 3g- .1-.3 mbps)
3.) If 4g is even able to connect, which is rare... it disappears and and is nowhere to be found, or be (re) enabled.
Attempted (unsuccessful resolutions):
1.) Performed Sprint recommended troubleshooting techniques:
a.) updated profile
b.) soft reset(s)
c.) hard resets- multiple
2.) contacted customer care: received "refreshers," and was walked through numerous settings and performed various resets.
Recommended CC resolution: return device for exchange.
3.) Sprint store attempted to identify problem, and in the process found that their demo, along with employee handsets (G2) as well as new unboxed versions had the same problem. They offered to switch to an S4 or Nexus5 for free, or wait a couple days to see if the LG rep could offer a fix.
(further) Resolution: pending
Here's the deal- I think we can all agree that this phone is kick ass. Therefore, I would rather not switch, as I enjoy the experience it provides, as well as the satisfaction of getting to really bond with a device when troubleshooting them. Though, this phone seems to be pretty 'buggy,' and while I don't mind tinkering with computing devices (been seeing the blue screen since win '95), I'm not sure I want to be dealing with the potential hassle with a device we all rely on day in and day out to be our life blood... plus, just because I don't see/haven't experienced the other issues others have, doesn't mean they won't potentially manifest down the road. :/ Maybe the Nexus 5 is the better choice... but it seems like cost cutting has taken place in a couple areas- battery (2300), and the camera. Almost like the G2 is the flagship and the other is mildly scaled down in certain aspects even though the end result is compelling for both.
Please know that I am scouring middle earth low and wide for resolutions, and have not composed this post without first looking and becoming familiar with other peoples similiar experiences. I will continue to fact find, and I apologize for not reading all related threads before posting, but time is of the nigh, as I am still within a time frame to return in case the problem is inherent to this specific device (a lemon). Plus, I don't quite understand everything you're talking about, as I've never had/chosen to dig that deep into the obscure settings and techniques I've seen listed (and also because I JUST got it) Hence, the user name- g2 n00b.
So thank you in advance for your time in helping with this. It is both greatly appreciated, and not without gratitude on my part. Also, I hope I displayed proper educate by formating this post in a manner which is easy to sort through. K. let the trouble shooting begin.
also, to the mods- sorry if this is thread/issue has already been covered elsewhere. I also posted this issue on another board and nobody had heard of this problem, so I am fairly confident that i may be justified in having poted this. However, feel free to delete/lock/merge/ if I just didn't see it.. but please provide the link so I can further fact find, because I'm stumped. Thanks.
I just did a speedtest on mine (Also on Sprint) using Wifi.
Same speeds I get on my PC.
It's an oddball suggestion but did you disable the Sprint connection optimizer?
Optimizer enabled. Though, I have tried disabling it and running diagnostics to no effect- doesn't matter what I do, it still won't exceed 3mbps, unless I am lucky enough to receive 4g in certain areas.. then it's a 'blazing' 3.5mbps, but usually .8. I have msl code and have adjusted band priorities and still no difference there, including ##72786 to reset default connections to make sure nothing was adversely affected after investigating the issue.
I'm really bummed. I love this phone. I feel like everything I felt I was missing in the S3/S4 are present here. Love the interface, form factor and all of the settings. Maybe I should take Sprint up on there offer to get an S4 a Nexus 5, but I REALLY don't want to go back to caveman battery hog status on the S4 and have to purchase a backup. I imagine the N5 is more efficient in this area, but it still has a 2300 battery vs 3000 in the G2. Needless to say, I'm frustrated and confused.. but often times, such is life.
Any thoughts on the N5, or suggestions to further trouble shoot are greatly appreciated and welcome?
I have disable the connection optimizer and have done this http://forum.xda-developers.com/showpost.php?p=47423537&postcount=1
The only other idea I have is hit up a coffee shop and due a speed test on their wifi.
The sprint stores by me have crappy wifi speed hence the coffee shop.
I seem to have mostly resolved the issue. I switched channels and encryption protocol. Apparently, my g2 didn't appreciate AES very much. Has anyone else seen performance differences with their device when comparing AES to TKIP? If so, are they drastic? I would think AES would be fine with the g2, considering how advanced it is. I consider it to be somewhat unfortunate if I am forced to select TKIP just so I can get a decent connection. That is, unless of course there are settings I can alter in the ##data# screen that can make better use of this encryption. Is there anything I can do now that I have narrowed down the culprit?

What wireless router are you using? I use a D-Link at home and my G2 kept connecting and disconnecting repeatedly. I was able to fix the problem by updating the router's firmware to the latest version. We've never had any problems with other wifi devices on our router, so it seems the G2 has some unique peculiarities WRT wifi.
I'm running AES with no issues, but noticed following.
LG (Sprint) connects first with a slow 72mbps and switches after a while to a faster speed of 433mbps
I have an Asus Router RT-AC66R, if I play around on the router with Frequencies or the wireless mode, LG would go down to a slow speed.
Don't have Optimizer enabled.
I suspect your problem is a router problem and not the phone.
