[Q] Limited 3g download/upload speed - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi all,
Here is an interesting finding from my i9000. I have recently found out this and don't know when or how it is happened..
I am not constanly checking my internet speed but realized a slowness in data transfer in my carrier while I'm on team hacksung's ICS build 12. When I run a test in speedtest.net's app, I couldn't get pass 45 kb/s even though 3g, HSPA and everything was on. I tried to narrow down the problem with trying with a different carrier and sim card; only to find same results. Tried my on sim card on a iphone (I know, but what you gonna do and reached 300-500 kb/s. So the problem was related to my phone...
Next, I decided to revert back to stock rom (XXJVU, latest one) to understand if it is rom related or not.. Apparantely it is not, I couldn't pass 45 kb/s once again. By the way I have formatted all (sdcard, data, datadata..) before flashing stock rom with odin. Now I'm back on ICS Build 13 from team hacksung and guess what..no change.
My basic knowledge limits me trying to investigate the source of the problem further so I kindly ask if someone has ever encountered something similar? I have searched XDA and net but found nothing similar.
Help is much appreciated..

I forgot to mention that I have tried different modems in CM9. No luck with the latest XXJVU modem as well (thanks_silkydude).

Check your build.prop file, it can be messed something... use this..., although written for another device - in my case works.

checked build prop, added the lines in the post you linked but no luck. The only difference is the speed lowered than the original prop. However let me remind you that I couldn't apply the attached zip file in CWM probably because I'm on ICS CWM.
Thanks anyway.

Here is the original build.prop for your review;

[Q] My most interesting problem ever

Hy everyone!
I have found a very interesting problem regarding my kaiser130 and android...or maybe the problem is in the user?
Anyhow my problem is that no matter which android build i try,no matter which kernel and which radio i dont have working wifi and data connection.
At first everything worked fine but then i had some problems and i didnt have time to fiddle around with android because it wasnt too stable and i had many FC-s so i had to go back to winmo.I had 6.1 on it before,have put on hardspl3.34 then started flashing android and after that i put back winmo from a shipped package with ruu . Now i have more time and i started to experiment with android again.I wanted to use cyanogenmod 6.1.2 but had the wifi-error problem but as i saw many other people had the same so i thought i'd go back to another build,namely incubus26jc's super froyo rls16 i used that for days but then when i had to use the apn or wifi it didnt work...or actually wifi worked but only with static ip,i tried switching kernels from a base one downloaded with atools to clemsyns and scoots but nothing worked for me better yet it even got worse it started producing the wifi-error again.I use the most recent radio tried both the emo version and the atw to no success tried installing both to nand sys on nand data ext2 data.img but nothing seems to be working and now no matter which build i try everytime i get the wifi-error and apn isnt working.Can it be that my bootloader is tarting to fail?Or is my kernel getting corrupted?
Oh and i always applied the appropriate module updates for each kernel.
Can somebudy suggest something useful or i was thinking that is it possible to very hard reset the phone i mean to put it back the way it was?Format the nand put back a normal spl,i dont mind trying thing again but i need the data connection and the wifi.
Oh and i forgot to mention the most interesting thing,when i turn on data it actually turns on and in the modem i can see that it even gets an ip address from my phone provider.

wifi not working [cyanogen/stock]

wifi stopped working i believe right after i flashed to the latest cyanogen mod, or shortly after. Today i flashed back to rogers stock froyo and still wifi does not work. Wtf is going on, did my router block access to it after cyanogen was installed or something?
any advice is appreciateed
3g still works.

Try some troubleshooting first.
Reset your Access Point/Router, or try a different router/ap. Flash back to 100% stock and do a "master clear".
I also find it useful to clear out the /efs partition after returning to Samsung ROMs after using CyanogenMod. Of course ONLY do this after you have a tested and safely stored a backup of your current "nv_data.bin" file. You have been warned.
Take out your battery and just let your phone chill for a few hours. That sometimes helps too.
Anyway, if after a complete flash to stock and master clear, and some troubleshooting with different access points you still get no WiFi signal, something may be wrong with your hardware...
From there you might either need to send it into a Samsung service center, or find a very technically minded XDA member to help you further. Good luck!

GalaxyS i9001 CM9 WiFi Problems

So, i Figured somethings wrong with CM9.0 alpha7 for the i9001 and that's something i've searched loooooooooooong enough to understand actually NO ONE has had this problem.First i had alpha 4 and with some searching in these forums i figured alpha 4 had wifi problems entirely.Then i downloaded alpha7........ thought my problems would go away but............. when doa clean install without the SIM inside my wifi works pretty good,but the moment i turn my phone off,insert SIM,and enter the PIN, my wifi...like,disappears on it's own.NOTHING WORKS!!!! i'm desperate to keep CM9.i even tried to wipe cache and dalvik cache and fix the permissions inside ROM MANAGER and form CWMR........NOTHING!!!! even got that dhcpcd fix thing that someone had posted,didn't work. and it's not just my home's wifi,i can't connect anywhere!tried rewriting wpa_supplicant file and the other stuff related to wifi(can't remember)with that wifi fix .zip fil manually, by flashing, using the files on other ROMs,NOTHINGGGGGGGG! WiFi only works with a clean reinstall of the ROM and WITHOUT SIM inserted. even tried with a SIM that had no PIN, same thing. i even downloaded AOKP,flashed, doesn't even boot.i don't wanna go around downloading every ics ROM i see so PLEASE give me a fix!!!

flashed LG G2 to PP and call log does not work, any thoughts?

I saw several threads regarding this issue (no call log - no incoming/outgoing/missed) and all appear to point to issues in phone app bundled with stock G2 ROM and having nv only flag when flashing to pp (only using 3g on pay go plan - of course, I could upgrade my plan to $29 to get 4g, but I never use data on my phone also I do not really use phone for calls/texts whole lot either).
So, I DID hear that installing other ROMs resolve this. However, I am GUESSING that loading other stock rom variants will PROBABLY not help (of course, if you know of one that works, let me know), so I am considering ROMS other than the ones based on stock G2 ROM.
Does anyone know whether G3 based roms (cloudy G3), or AOSP roms fix this issue?
Now, I did try to load several replacement dialer/contact apps and that did NOT help so it must be something deeper.
I guess if nobody have experience, I guess I will try it out.
BTW, My rom is 4.4.2 stock build 24A. Do I need to flash KK baseband before going to Cloudy G3?
(4.4.2 is already a Kitkat, correct?)
I already have root and have TWRP installed (which means that I can install ROMs in alternate slots, correct? Sorry, I am coming from Droid RAZR which works that way)
Thanks.
Got the call log fixed by flashing G3 ROM.
The 3g phone flash was kept without any issues.
Now the call log works, but stock SMS still does not work, had to install textra and it works fine.
After installing G3 ROM, the MAC address changed to something funky, my wireless mac filtering was going crazy and I am assuming that due to duplicate mac address, my internet occasionally got cut off (like watching youtube vid, etc).
I fixed this issue by:
edit: /data/misc/wifi/config
file, replace
cur_etheraddr=xx:xx:xx:xx:xx:xx
where the xx'es represents your actual MAC address (what it originally was).
Now, I did it before and it kept putting back the phantom address right back. LOOKS like this file gets generated upon reboot from some script, but looks like the reading off the MAC address from wifi card is not working correctly or something.
KEY for me was, after updating the file, set the file permission to read only (r-xr-xr-x). I used the ES File Explorer to set the permission.
And then reboot the phone and wifi will come back with correct MAC address.

[Q] "Not registered on network" error. *PLEASE HELP*

Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.
Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.
