Slow Wireless Tethering in Samsung based ROMs, fast in CyanogenMod?

See new thread here:
http://forum.xda-developers.com/showthread.php?p=11040825

Confirmed. On darky's 8.0 (XXJPY) right now with speedmod K12M.
Mobile AP is unacceptably slow.
HSPA on the device itself is blazingly fast though.

As stated in OP I believe this is a problem with all Samsung based ROMs, stock or custom. Not sure if it's carrier related (I'm on AT&T but they should have no impact since I'm using an unlocked device that I didn't buy from them).
Hoping some folks can help shed some light on this. I'm still learning but not advanced enough to try to find the problem.

Nothing? Surely I am not the only one who feels like this is a big problem...

You are right. however i tried with JP6 and i got the full speed on my network provider with mobile AP. But in darky's and other roms, i noticed that problem too. that dosen't mean JP6 don't have this problem.
I'm just saying

This was stock JP6 that worked? What modem?

I'm amazed that this isn't a huge issue for people...anyone care to post a configuration that they know is working full speed? For me using CM isn't an option due to battery drain, and having to flash it on everytime I need decent wifi tethering is a huge pain.

Been using CyanogenMod for a while simply due to the fast and proper tethering, just disappointing that I have to give up good video playback and other features just to get decent tethering.
I'm wondering if this is a project that one of the devs could look into. I should have posted this in General comparatively no activity here in Q&A

[Q] Which ROM/modem? AT&T, GPS, HSUPA

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.

[Q] Hello there, can someone here recommend me a ROM please?

I'm a new user here (yes...I read all the faqs) but I'm still not fully aware of the ROMS available and their respective benefits. Didn't really see any threads that helped me in the captivate section.
What I'm looking for most is excellent battery life and signal (if that's possible). I tried Cognition and it seemed alright for a bit but then my signal became spotty and battery worse (not sure if it was the ROM or my phone).
If it helps: I'm on stock froyo (on Rogers).
I'm not really interested in a multitude of features that may overload my phone, I'm a minimalist.

You could always try flashing a different modem if you're having issues with signal.

It depends on what city u live in...if u live in an urban area, then I would recommend the jl3 modem
As for roms...cm7 gets decent battery..
U might wanna check out a rom called juiced which was made for battery life...I get 4 days of light usage on that rom!

I've found Continuum 6.1 to be the best operating gingerbread ROM for my phone. This after experimenting with pretty much every other ROM out there. Battery life has been good.
I'm a moderate user. Mostly sms and music. I get 2 full days out of a charge when running the music app 2 hours per day and sending 20 or so texts.
This is purely anecdotal. My wife's phone got poor battery life out of the same ROM. Just going to have to try one at a time until you find one that works well for your phone.
Good luck.

Are you looking for a ROM based off gingerbread or froyo?
I would recommend a froyo based rom for stability, serendipity 6.4 treated me pretty well when i first started and now i'm on fasty 2.3 which is pretty good too.
If you live in the northeast USA then i would suggest JW2 or JV5 for modems.
(See this link for modem options and good discussion on the topic, http://forum.xda-developers.com/showthread.php?t=876391 Ignore the poll, its out of date.)
If you want to try out the tasty goodness of gingerbread then i suggest trying serendipity 7 or the leaked "stock" 2.3 ROM thats been out for a month now.
Keep in mind that you are more likely to find bugs and random problems with gingerbread ROMs since most (all?) of the current ones are not based off of the i897 captivate ROM but the i9000 instead.

Ok, i think i got it all here.. Now grab yourself a snack and start reading!

You're going to get a multitude of suggestions being that everyone has their own favorite. What works for some may not work for others. I personally have found that I can get healthy battery life out of most any rom I flash using an OC/UV app. Usage and location has a lot do with it as well. Your best bet will probably be to try different things and explore on your own til you find what works for you. Luckily there are tons of people in these forums who are eager to help and lend advice. I certainly wouldn't have learned as much as I have without them.

Stability and battery life = serendipity 6.4.
Stability on gingerbread = serendipity 7
Awesome features(but you don't want these based off op) = MIUI
Sent from my I897 using XDA Premium App

For a froyo based ROM ill easily agree serendipity is the way to go
And look into the onix kernel
For a gingerbread ROM try either continuum or apex, but avoid the betas just use the stable releases
And look into the talon kernel
Both kernels I recommended are by the same dev and are capable of overclocking (which you don't seem too interested in) and undervolting (this will help with battery life)
If you want to overclock stick with 1.2 ghz, anything higher is usually unstable but you could get lucky, 1.2 is safe though.
For undervolting read around for the guides to oc/UV. Make sure you have a way to wipe your voltage settings if you mess them up (should be built into onix's recovery, and its definitely in talons recovery)
No matter if you choose froyo or gingerbread and whether you use any of my suggestions above, look into the gingerbread bootloaders (try to avoid the i9000 ones, even though they work on the cappy they weren't made for us) I don't know if there are rogers bootloaders for gingerbread but I know the att ones work great and you can probably change the logo later.
The gb bootloaders are obviously required for gingerbread roms, but will work with froyo roms as well, so you may as well grab them now.
As for signal read into modem flashing, make sure you get cwm2 flashable modems for cwm2 recoveries (like onix) and cwm3 flashable modems for cwm3 recoveries (like talon)
Your best bet here is trial and error
Jk4 seems to be a good fallback modem for functionality (no frequency dancing issues which can cause roaming or no signal) but I'm not a fan of its signal strength in general or battery life, personally I like kc1 and zsjpg depending on what region I'm in.
Anyway I hope this info helps

Try them out for yourself. We can give you what,works for us but might not work for you. A search would have told you this. Thread closed.

How to port GB
Does anyone know the steps to make the O3D leaked GB rom work for the Thrill? If there are any experienced devs out there, that maybe dont have the thrill to work with anymore (bc most switched to the SGS2), could give me a walkthrough or an idea of where to start that would be great! I have a machine running ubuntu, an 06 macbook pro w/ OS X Snow Leopard, and an hp running W7 and the Dev release of W8 (dual boot). I have never cooked any ROM before so i dont know what exactly i would need but i am sure i can find that info somewhere on XDA... but, the more detailed any help or ideas, the better!

Hey I have some experience porting roms and building cm7. When my donated thrill gets here next week I will look into this more.

It's running...
First backup/write down your apn & mms settings, there are lots of info here on the forums to do this, or an app like this: http://android.riteshsahu.com/apps/apn-backup-restore.
Do a full nandroid backup to your sd card to be safe.
Follow the instructions on this post: http://forum.xda-developers.com/showthread.php?t=1331814 to get the o3d rom running on the thrill, it's a fairly long process, but not too bad.
Replace your APN and MMS settings, 4g disabled, everything else is mostly working it seems, though my wifi is a bit wonky so far.
OOOOR
Wait for a dev to build a solid custom rom!
Good luck!

Do you guys think this'll resolve wifi reception issues? I've been tolerating this crappy phone for awhile thinking GB will solve the battery issues but in the past few weeks I've been doing some business travel to Boston, Dallas and LA the GPS has been completely inadequate on all three trips. It would take up to 20 minutes to get initial GPS signal and then even when it does have GPS it would go in and out of GPS reception every minute or two. I'm so fed up with this thing. Yes, I read the 'GPS fix' thread and had already implemented the 'fix' but it's not any better.
I bought it at Costco, therefore, I'm thinking Atrix2 since the Galaxy S2 is a huge price diff. If I had the option, I'd trade it in for iPhone4S.

GPS has been working well on quite a few users phones, and I can personally attest to the the same. I also haven't had any battery issues with the phone at all. It might be a software issue or hardware, but you might want to try exchaning it for another to isolate it. For me, it has been a great phone so far, and I expect a great GB rom to only solidify this.

My wifi and gps work fantastic... you might have a dud... if its within your month swap it out... it sounds like 25% of these phones have bad bugs...
Seriously this is one of my favorite phones of all time... wouldnt say that if i had those troubles...

Gingerbread has brought some great changes to the infuse for me. Better battery life and overall performance. I would say that the same would go for the thrill. I will be getting my thrill just in time for my Las Vegas trip so I will put the stock rom with root access to the test!

Back to the topic of getting the leaked gingerbread rom running on the thrill.... has anyone else tried the instructions I posted? Would like to hear others results especially concerning wifi...

I might try it later tonight or tommorow... trying to write a research paper on precambrian evolution at the moment though.
i'll try it out and post my results hopefully by sunday though...

Its not looking good for the leaked gb running on Thrill. The rom itself will run but Apparently LG changed the baseband for gingerbread. You can install the o3d baseband and you will probablly be able to call/text. But you wont be able to use data. I NEED my data connection for sending emails out in the field so that's a big no-go for me.

Best Modem for JVT?

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.
