[Q] Weird problem, need help ASAP - Galaxy S I9000 Q&A, Help & Troubleshooting

Well i use my phone for work alot and it requires internet. I'm currently using the MilkyS ROM and the first time I flashed it my phone was probably slower than the stock 2.1 but internet was working fine. So i eventually got sick of the speed because games would lag and even general navigating. When I reflashed it the speed was fine it was great infact however my 3g started playing up it shows the 3g symbol, the APN is fine but the data connection is very unstable it might work for 2 minutes then drop out and stop working for 10 and the 3g symbol sometimes disappears when this happens! I'm becoming extremely frustrated please throw all your ideas at me. is it the modem i have to install with milkyS? will it solve the problem if i don't flash with the modem? thanks!!

Well buddy i think the problem is with the carrier !!
My SGS also have the same problem ,i found it out that some places couldn't get perfect 3G coverage that makes our signal reception to stutter,I changed the option to GSM only from GSM auto(PRL)in Jetpack v5.1 JVS this made the signal stable but my 3G is gone....
its even the same in JVQ too and my friend's SGS also does the same,it even did happen to my old MotoDroid/Milestone.So i think its a carrier issue...!

I don't think it is I think it has something to do with modem compatibility because I get the 3g symbol and every so often internet works for a bit of time but then cuts out and it just shows 3g sending but not receiving and sometimes the 3g symbol will disappear. I only had this problem when I tried to reflash the ROM. My reason for reflashing was slow phone speed for some reason but internet worked flawlessly. I had the same issue with the internet with the darky's rom too so I'm not sure of the issue but it's bugging me!!

If you are confident that its a modem issue then try CM7 and these threads maybe useful!

[Q] -0.00 Speedtest.net results

Has anyone seen this before? I am getting a -0.00 results in SpeedTest.net in my N1. Actually, all the tests that I ran appear to be very inconsistent, going from 3.5Mbps to the -0.00, from one test to the next, so I don't know if it is my phone or the t-mobile network. I did a couple of test over wifi and those were very consistent results.
I started having this problem after flashing Rod's MIUI mod, and then going back to CM 6.1.1. I did a complete reinstall of CM and flashed the radio and no changes. I am not really aggravated by this problem, but it is kind of annoying, as my data transfer is very slow some times.
Any comments will be highly appreciated.
I get that sometimes if I have the app open and switch between wifi and cell network, or vise versa. I just close the app and then reopen and it works fine.
You might want to flash your old radio back (if you changed it).
You can also try flashing the radio prior to install of new rom.
It's tmobile network. Cuz you gotta watch the data connection indicator on the status bar. If theres no arrows go up and down the connection is weak, very weak or mostly no connections at all.

Problem connecting to my network Please help!!

the weirdest thing happened to me, my phpne was working fine, i flashed fearkill fr13 after a full wipe coming from fr12 mcr.
It worked well for a couple of hours and all of the sudden i cant connect to my network. The only way it connects is by enabling 2g networks only and even like that i cant make any calls. I have even tried reinstalling the baseband 405 and nothing works...
My network is fine by the way, its just my phone
Please help me!!
Edit:
A little more info:
I tried a different sim card with the same results
Whenever i try to search for a network it just stays thinking for a while and does nothing
When I try to do it automatically it says it cannot connect to the network at this time immediately...
I managed to make a call on 2g networks only but as soon as i remove the check i cant connect
Edit 2:
Woooooow, this just gets weirder by the second!!
I can connect to the internet with wifi disabled and a clear X on the network as in no network connection... I can browse the internet just fine, NO CALLS though
... after countless Wipes and installing plenty of roms With no luck i gave up and as soon as i Woke up it Was Working again... strange but im happy
Guess it was your network after all
maybe, i had a blackberry beside it with a working 3g connection :S
And no idea how to explain 3g working with no bars and an x on it haha
O have problems with my network connection too.
In some rooms at my house I can get 3G access and in another room only EDGE.
Several times per day I can't get access to the network anyway. The only way to solve the probölem is to restart the phone.
Sometimes my phone tells me it is connected but there is no data transfer for several hours. I noticed that when I got home and many emails from the last hours appeared after being connected to my wifi.
I'm using the MCR but I've also tried the ROM from romkitchen-org. Changing the baseband had no effect.
I'll have a try with the stock ROM. If this would fail too I'll send my phone back to the dealer. I think it could also be an hardware defect.

Weird Data Problem Please Help

Ok first of all up until today my phone has been running JPY with no problems.
Now today i can use the stock browser to browse the internet but its very slow, If i use opera mobile like i have for the past few months i cant connect to any pages as it times out saying "connect to server".
Sometimes the market works sometimes it dont and its just took nearly 10 mins to download a 2mb app.
Now i have reflashed JPY using odin and still have the same problem, i have also tried a sim card from my other phone and it does the same with that so can only be the phone, I have hard reset the phone and still nothing.
Any ideas?
Also cant even download email unless i use wifi then everything is fine, Checked apn settings and they are all ok
Is it possible that the problem is caused by your service provider?

99.9% sure its nothing to do with that as my other phone on the same network works fine, as does my sim in my other phone, im certain its something to do with the phone.
I'm having this issue too.
Data only actually "works" about 1/3rd of the time, it connects as "H" (HSDPA) and occasionally drops to "3G", but doesn't consistently work.
I've tried disabling HSDPA and I get the same issues.
I've seen reports of other people with similar data issues on Gingerbread...
I don't want to go back to Froyo, but will if I can't get data working more consistently...

3G trouble with CM 10.1 on Vodafone Egypt sim card

Hey,
I recently flashed CM10.1 on my note and it's working perfectly well on WiFi, but when i switch to 3G, some apps don't connect and show connection timeout.
I did some digging but found no solution to this problem,
when i tried using market access, 3G connection worked on all the apps it didn't work on before...
Any idea how to fix this issue without having to use market access?
Are you sure your apn is properly setup?
Also you may try a different modem.
Sent from my GT-N7000000000 using Tapastalker 2
I had a problem that from day one (or maybe since I got my ICS update) my 3g was so slow I couldn't use it... when I did a speed test on it I was getting download speeds of 1-2 kbps MAX, upload was 0-1kbps from what I remember. But switching ROMs never helped. When I changed my modem however then I think it fixed the problem... but I haven't had the chance to test it (poor 3g signal where I live). If I were you then I would flash another modem, which one are you on now?

All networks lag or not work after updating s6012 to jb

After updating my S6012 aka Samsung Galaxy Music Duos to JB by looking at this guide..
http://forum.xda-developers.com/showthread.php?t=2415442
My phone networks 3g and WiFi have lags..
In WiFi mode it connects but network is not found..
In 3g mode it takes so long to on even www.google.com..
Anyone else have same problems??
First time i did it worked fine then few days ago i sent the phone into bootloop and then did it second time two days ago..
Please help..
Did you factory reset after the install?
verify the connection first
Well i didnt factory reset and i use the WiFi network for some time now on my laptop without problems..
Now WiFi works for few seconds before it shows no connection.. It downloaded a 1.1mb file before the message came..
Any ideas why it is doing so??
Is it any settings or is it any root app??
Want fix soon as i need my android for mobile forum using..
I've found that many OTA updates cause weird issues if you don't reset afterwards, especially Samsungs. What did you do to make it go into a bootloop the other day? Is it all wifi networks that are having issues or just at home? Have you tried forgetting the network and relogging back into it and / or resetting the modem and the router if it is only at home? It doesn't matter if every other device is working, resets can often help if you have narrowed it down to just 1 network. As far as the 3G, it's hard to say. The modem/baseband also updated and not every version works best in every region. It's possible you might see if there is another version of 4.1.2 that would have a different modem to flash.
i tried activating softkeys in my rom by editing build.prop..
tried forgetting and relogging..
strange thing is 3g network lags less..
it's as if it is getting better as days pass by from flashing..
Working
I updated My ROM to CM10.1.3 by Alonso..
Now everything is perfect..
