[Q] WiFi dissconnects on 2.3.5+ firmwares - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey there.... was just wondering... Is there really no way to solve the wifi bug in the 2.3.5+ firmwares ?
I did check other threads but ... changing router settings is not an option for me...
Tnx in advance

I never encountered this kind of problem, try flashing the new JVU, or ICS....
I was using JVT with Semaphore 1.8 for a long time and I never had this problem....

I had this problem when I moved from Froyo 2.2.1 to Gingerbread 2.3.3. I solved it for me by flashing the modem (baseband) from Froyo 2.2.1 that I had been using before.
Now I am on 2.3.5, still with the Froyo modem.
Very stable.

I tryed every single version of android available for SGS ... and first time i encountered this problem was with the 2.3.5 firmware like many other SGS users ... thats why i`m asking for a solution ..
tnx anyway you 2

I fixed this by going into my router software and setting dhcp lease time from always to 2days.

This problem is a known bug in the 2.3.5 firmwares i had this bug too after uprading form 2.3.4 to 2.3.5. To solve the problem you have to change the DHCP leasetime in your router from "for ever" to any other value like 2 weeks(every other value except "for ever" will work). If you don't want to change your router settings you have to live with this bug or downgrading to 2.3.4(with JVR i didn't have this bug). As i know there isn't an other solution for this problem..

I've got this bug in 2.3.6 as well but like I said changing lease time fixed it.

Yes that could be. I didn't try any of the 2.3.6 firmwares so I can not confirm this. But if he doesn't want to change anything in his router he could try the 2.3.4 JVR. With this Firmware the bug definitly does not appear
So at the end he has to decide if he wants the latest firmware with changin the routersettings or has an older firmware without changin the routersettings

tnx guys but that i know ... but as i said in my first post ... changing router settings is not an option .... since i have no access to the router at my work ...
That is why i wanted to know if there was any other chance to fix that other then flasing 2.3.4 or changing settings on the router

Possibly try fixed IP on your phone?

What if you flash latest XXJVU 2.3.6 rom and modem from JVR?
Should be worth a try since Froyo modem goes well with 2.3.5

Nothing works ... i get disconnects on every modem .. no matter FroYo or GB
Tnx for the effort all guess ill just have to stick with 2.3.4

Try to change kernel to Semaphore or Midnight.
The latest of those kernels run any version of GB.
Thx for reading, press THANKS if u like

try flashing other ROM's it might be ur ROM has bugs

I don't have such problem

[Q] Wifi speed issues with 2.3.4

I'm experiencing incredibly slow WIFI since upgrading a ROM and wondered if there is anything I can do about. 200k down - 20k up and pings anywhere from 600ms to 1500ms. It also fails and reconnects.
Could the problem be related to the modem that was installed with the ROM? I'm unsure is this effects wifi speed? 3G is fine and running as it normally would.
If it isn't the modem what is the nest way of diagnosing issues with WIFI? what should I try re-installing / overwriting?
It's one niggle in a very stable smooth ROM.
I'm running the following if this helps anyone;
Phone model is a GT-I9000
firmware - 2.3.4
baseband I9000XXJVQ
kernel - 2.6.35.7-I9000XXJVQ-CL281085 Ficetobeast #darkcore_2.9.2_JVQ
Build Number - DarkyROM JVQ v10.2

try a different kernel as i do believe wifi drivers are contained within the kernel
Many thanks. Is the modem part of the Kernel then? Should I try the darkyrom site to see if they have a different kernal for their ROM?

no, the modem is seperate, some people say modem effects wifi, others refute this...from personal experience i have found quite big differences with kernels, so yes, try on darkys thread for suggestions for alternative kernels

Help with MODEM on JetpackROM+Semaphore 1.7!

Guys , iv'e noticed that my battery'd draining on JVQ modem so, i would like to change it to JVR but even after using the jetpack rom tool,SGS kernel flasher the baseband remains same it says "XXJVQ" . Any ideas on changing the modem??
I9000 on JetpackROM v4 + Semaphore v 1.7 JVS.
Not sure, but doesn't Odin support only modem flashes too?
So, if you download eg. Stock JVR rom from samfirmware and flash only PHONE-packet, it could work.

semaphore kernel for my GB 2.3.4
or any other way to have a strong wifi signal and strong network signal
thank u
You can find all semaphore kernel releases here: http://www.semaphore.gr/ in the download section.
thx sir..but as i've heard can it make the wifi and network signal stronger?
or there is another way out there?
thank u
For stronger network signal u need to change ur modem which is flashable using odin...
Modem shows its work on phone network...
Kernel shows its work on wifi...

Why use odin when you can simply flash through cwm.

I thought as he has flashed semaphore in gb so he might be well versed with odin... why confusing him with cwm...

Because you have more ways to screw up your phone with odin compared to cwm. Its not that hard to use cwm recovery imho

thank u..

It takes about 10 seconds to flash a modem. Most of them are small files. Just flash them give them some time for testing and get a new one if the one you tried does not work.

Probably a kernel issue, Try switching a different Supported Kernel, Also post in his ROM thread and / or search to see if anyone is having the issue.

Install SpeedMod 3-9 kernel - it solves both WiFi and BT issues and is excellent on battery life.
I am using it for 3 days now and still very impressed.
Notecore V4 with Criskelo 9 here and no problems with WIFI and BT.
Same problem

Before changing kernel try a different modem. Mine started working after flashing LR1 modem from Aroma installer.
Sent from my GT-N7000 using xda app-developers app
i had the same issue when selecting the cf-root kernel, a reinstall at a later date using the speedmod kernel didnt have this issue
try the new fix 9.1 in developers section (criskelos)
