Anyone got any solid advice, fact based evidence on how to sort out out dodgy GPS signal on ics. Tried many modems, many gps.conf files, they make a little difference but still nowhere as good as GB. Currently using slim 3.7 on semaphore, thx dudes

Allegedly, the JW4 modem ICS to work well. Tested themselves I don't have that but yet ^^
thanks, tried jw4 and jvu, these were fine on GB but not on ics, so it must be something else, just need to find out what

try JVT modem from the modem thread in here somewhere. it has good signal and else on ICS. Im in ireland and have no problem with reception or gps. hope it will work well in uk.
cheers mate, tried jvt (and a few more from perkas stash) wiped cache/dalvik, still dodgy grrrrrrr,
was great on GB, 5-15m, no drops, as soon as i flashed ics, its 10-40m with dropouts, was the same on cm9 and slim, annoying as i use navigation a lot, thx for reply
oh, i do get a decent fix when stationary, then it loses the plot a bit when i start driving

Been looking around other forums, it appears that ics does provide a dodgy GPS signal for many phones. Thats that then :'(

Noticed that, too. On any ICS ROM I tried GPS signal is very jumpy, fixes take ages and the refresh rate of the GPS signal is every 100-300 meters.
Flashed Darky ROM 9.5 to see if the battery runtime is indeed as good as everyone states (in my opinion better then GB but equal to ICS) and experienced fabulous GPS performance, fixes in 5-10 seconds and constant GPS signal. However there might also be GB ROMs that are equally performant.

I haven't flashed a new ROM in awhile and really don't want to have to go through every ROM/modem combination to find one that works for my needs. I know plenty of folks here go through almost every ROM that is available so I'm hoping to pick your brains.
1) I'm NOT asking "what is the best ROM". I <3 -all- of the ROM authors and don't wish to start that kind of mess.
2) I'm willing to try a couple of combinations to see.
3) My Cappy is brand new (I just exchanged my old one under warranty since I was one of those in the original batch that got the lovely random shutdown issue even with 2.1-update1) ... not sure if that is going to matter or not but I've read a lot of posts that seem to make it clear that different Cappy batches behave better with different ROMs.
So ... what I'm primarily looking for:
* I'm on AT&T so I need 850
* I would REALLY like to get improved GPS performance ... I don't want to buy a standalone GPS (wife has one, I'll use it when I have to) ... right now even with the GPS tweaks like Skyhook I'm just not getting acceptable lock times and it loves to break lock.
* HSUPA ... I'd like to enable HSUPA. I'm fortunate enough to live in an area with a new 3G tower and small population, which means I know there is more bandwidth available so I might as well use it. Especially since on occasion I need to tether.
* I don't want to lose noise cancellation
* I would like a ROM with good battery performance
Otherwise I'm not concerned with new features ... besides the issues above I do fine with the 2.1 ROM (not saying I don't want 2.2, just saying I don't care whether the custom ROM includes custom launchers, themes, etc). I would -like- working Bluetooth + HSUPA but my version of "working Bluetooth" doesn't care about voice dialing.
PS. I've read a number of threads on ROMs and modems ... but my brain hit information overload once I started trying to match up both. I probably could have settled on a single ROM -or- modem, but trying to get them to mesh well just didn't compute.
Everyone has different experiences with different roms. I know it's a cliche but it's true. I've had pretty much no gps in a rom that boasts about gps. Best to try each rom and see if you like any.

Personally I love my combo of darky's 9.1 with suckerpunch oc/uv kernel and the tjl3 modem. I really haven't used the gps much and so I can't say about that (make sure to use faster fix to get the right region). The battery life is all day for me and I use stereo bluetooth headphones all day. I really like the look too. I don't know if it has noise canceling though. Hopefully this is helpful.
HSUPA requires an I9000 based ROM with a matching modem.
I'm using Serendipity 5.0 with a JK4 modem.

The only way to have noise cancellation is to stay with 2.1. From what I understand, att is the only one to have included the noise cancellation chip and since we do not yet have an official Att 2.2 source we can not take advantage of the chip.
Not sure on this one, but doesn't i9000 based roms have the bt static issue? And is the i9000 roms the only ones that let you have hsupa? Sorry a lot of information is on this site and I am trying to learn as much as I can.

Started with the included modem (??), flashed jk4 with CWM (didn't help), moved to Telus JL3. I like JL3 better right now.
Just know that you have to pay attention to what ROM you're using. If you're running a I9000 rom, you have to use a I9000 modem.

Also using Darkys 9.1 and find the battery life is great. The only I see is wifi stops connecting after 1 day or so, but a reboot brings it back up.
What improvements did you see with the suckerpunch kernel?

first of all I installed MIUI rom a week ago ..
it took me 2 hours to just do that..
then I figured out that people are flashing thing called "kernel' which apparently makes phone faster. So i flashed glitch kernel
then I noticed people talking about modem..
what does this modem do and what is the best modem for miui rom?
thanks in advance
I am a super newbie as well.
But I think people change their modem because sometimes the phone signal (3G/2G or whatever) is just too lower than the usual.
It seems to be different phone to phone. But if your phone signal seems normal, you don't need to anything (I guess )

Modems are the software that establishs and controls your phone, data and gps signal. Some modems work better in certain regions or with certain carriers. Some may be best with gps, or shine at data transmission. Also if your phone supports the 850 band you will need a modem that supports that. Getting the best signal you can is important because the sgs can burn a lot of battery life seeking and finding a solid connection.
Modems are painless and quick to flash via recovery, so it never hurts to try a few out to find the best for you and your usage.

Hi,
what Modem would you suggest to use with GB JVT?
My wifi signal is always rather weak (no or poor signal, when other devices still have a good connection) and I also have GPS issues sometimes. I was on JVQ till today but JVT modem does not seem so be any better.
I can still remember that both, wifi and GPS worked much better when I was on Froyo...
Any Ideas?
Semaphore kernel, fastest ive used, and most reliable and has support for init.d. if i helped please click on the thanks button
Im inthe UK and found exactly the same as you. Having tried a few modems im settled on ZSJPG. give it a try m8 see what you think. Not sure on battery drain seemed no more than the others but it keeps signal where JVT and JVQ was struggling.

Did he ask about kernel?
I have been using ZSJPG too. Best for me. You should really try it out
Likewise, ZSJPG is the best for me too. I found battery life is loads better with it as well, I believe it's a Japanese modem that's been optimised for use in built up areas though so it may depend on the area you're in. I'm in London, and it works amazingly for me...

He spoke about Wifi. This is controlled by the kernel.
GPS on the other hand is controlled (AFAIK) by the modem.
When I was in Deutschland I ran with KG3 and it was good for both battery life and speed.
I have tried ZSJPG and that's excellent for battery life and for call quality. I found it did dodgy things to my GPS and the download speeds.
So from what cointry sre yoy? Im from germany and like tje jvs modem

On XXJVT now and the JVT modem gives me no issues but I'm on Teamhacksungs ICS Build 6. Seems to have pretty much bugger all standby battery drain unless you sync google photos to your Gallery or involve the stock email app.
it all depends on the locations you're from ZSJPG is for mainly asian countries but it works a charm on other countries i recommend you go to a german galaxy s forum and asking there such as GOAtools.de to ask
I'm currently switching up ics roms and kernels to see which works best for me but I do not understand modems so I need some help here. I saw jk4 on the map close to me. I live in jacksonville fl and commute all around the city and west of jacksonville daily I was wondering which ones to try out.

Just start downloading them and trying them, giving them about 2 days before you decide if you like it. Several factors to consider are call quality, signal strength, battery life, and GPS reception. Since your using ICS roms, you must use the modems packaged as CM7/MIUI. You try using something else and it won't flash.
Look >>HERE<< for all the modems you would ever want to try. (FWIW, I like BVJWW2)
Like mrhaley said, there are a variety of things that affect it. JK4 worked great for me when I was in Florida, so I would start there. JW2 is nice also, but it seems like people can't hear me as well with it.

JK4 FTW! I've stayed with it since Eclair and it still works great now I'm on THS ICS. Great starting point to try out.

I'm not sure about better battery life but call quality, data speed and connection stability will definitely improve if the modem is right for you

Better battery life will happen if it gives you better signal strength in the areas you spend the most time.

Hello guys, a few days back I flashed teamhacksung's CM9 ALPHA for Captivate (BUILD 17) on my wife's phone, but she has told me that her apps are not syncing outside of a wifi connection.
I'm thinking it might be something related to the modem.
So I'm looking for any advice on which moden should I load, considering we live in Venezuela? Any tips?

Someone listed the "UGKC1" modem in use in Panama. You might consider UGJL2 or UGKG3 also, near by. Search "soggy cashew captivate modem" and check the map. Update your own listing if you find something that works.

There are some more remarks on this in the CM10 dev thread. I'm experiencing the same (on stock and Semaphore kernel), but it seems the wizards are not quite sure if the wifi signal is indeed weaker than before or it's just the indicator that reports a weak signal.

Well, but sometimes I'm losing the connection, with CM9 this doesn't happen. So I believe the signal is indeed weaker.
With my tablet (also CM10) there are no problems - same strength as CM9.
I cant even connect to a network that was once strong on cm9
well, same prblm on DHD too.used all the roms in my room perfectly but jellytime get dc all the time so its nt just indicater prblm...
its very good for me
thats because of the feature in jelly bean
try system setting / wifi/advanced/ then uncheck avoid poor connection... may it will help
