Portable hotspot not working in 2.3.4

Has anyone noticed that it is not working on KG1 and KG2?
Just realised it today and when flashed back to 2.3.3, it works again.
On 2.3.4, able to get IP from DHCP but unable to surf.
And as far as I googled, it's probably a kernel issue.
Anyone having the same issue?

working in KG1 here

It's working on my KG2 also.

Thanks guys for the replies.
Can inquire if you are using stock or custom rom?
I am using stock rom with chainfire kernel.
What perplexes me is that it work in 2.3.3 only but not 2.3.4
Even tried it the moment I do a factory reset KG1 without root but no go.
Appreciate any advice.

Try to set the security to WPA2, I think it has something to do with your APN setting or fast dormancy setting.
BTW I'm using stock KG1 firmware with no modification and portable wi-fi hotspot is my only way of connecting to the net.

Just reflashed.
Step1: KF1 (2.3.3) - Factory reset was done. Both tethered and hotspot works.
Step2: KG2 (2.3.4) - Factory reset was done before and after upgrading. Both instances,hotspot not working. Tethered works fine.
APN settings remained unchanged. Fast dormancy unchanged (this shouldn't matters in the first place).
The problem occurs only in 2.3.4. Anyone can advise?

Have you cleared your Dalvik cache and wipe cache partition before flashing KG1/2, usually what I do is wipe those cache and its partition, wipe data/factory reset, install new firmware, factory reset again. These steps will surely wipe clean your phone.

Yup.Tried them all. Even tried overlay flashing of stock roms in hope of solving it.Just couldn't solve it.
No matter. I do with wired tethered for now. Hopefully the later roms can solve this perplexing problem of mine.
Thanks for your help.

Just tested on my GX2, Stock KG2 2.3.4 ROM and rooted with CF-ROOT XXKG2 kernel. No problems.

Then can someone enlighten why is this so?
All my tests so far are with stock roms, pure Samsung bundled apps. I didn't install anything while troubleshooting!
KG1 - i9100XXKG1
KG2 - I9100XXKG2
KF1 - I9100DXKF1
Does the country code actually makes a difference?

Weird thing.
Working fine here too, just used it last night to surf around a bit.
XXKG2 2.3.4 with a kinda messed up kernel ATM

working on KG1 without problems...

I've also had major issues with my HotSpot too, tried many different ROMS and Firmwares and nothing worked. My brother and I both have the same phone, purchased from NewEgg.com and believe it's the European model, I upgraded mine to 2.3.4 via stock at first, and the HotSpot didn't work. I can see the connection and connect, but no data is pushed through, and not all devices can connect, only certain ones. Then tried countless ROMS, and none of them work. But his HotSpot works, he is still on 2.3.3. So I can confirm issues with 2.3.4. I wonder if the Puerto Rico model would be any different.

To resolve this, you can flash any of the custom kernels here. They are build on 2.3.3 source and hotspot is working.

I'm currently on NINPHETAMINE kernel 2.0.4 because I want BLN support. Is there a 2.3.3 kernel that supports that?

Working on KG5, but I have to change the user agent of firefox to mobile android OS

Not sure on that kernel but speedmod's and hellcat's works for me. It stop working the moment I use the stock kernel or chainfire's.

Hi, I too had the same issue with Hotspot, but now I fixed it!
when I was on 2.3.3 (with Org rom from my provider) Hotspot was working properly! after moved to stock 2.3.4, I couldnn't use the Hotspot option. (After activating, my data connection would come and go).
As djpianz sugested, Its got to do with your APN.
What I did is, Go to APN setting, press Menu --> Reset to defaults.
Problem was solved. (I guess If reset doesn't help ya, You need to manually define your APN, Or use Titanum backup to backup from 2.3.3 and restore to 2.3.4).

No really. I do have the same problem. I've tried installing different roms, different methods but still the same problem. I think its a problem with the WiFi driver Samsung has created for ICS/JB

i did install XXLQ2 but wifi still not working !!!

i have flashed the official rom but my device disconnect automatically after about every few minutes but able to reconnect!

yes same here but you will be lucky if u can reconnect sometimes u have to reboot to make it work again !
Still no solution , hope someone finds a way to fix this

I have the same problem after installing with PC ODIN.
I flashed back to HC and back to ICS Hong Kong version and it's still resetting Wifi every 10 secs.
I've now installed Wifi Fixer from Play Store and it is resets it faster and holds the connection longer.
Although it still persists Wifi Fixer seems to improve it to the point where it's bare able.

Get Wi-Fi fixer from Play store. I did, and it works magic!

Update;
Well, Wifi Fixer only seemed to work for a few routers.
The one at home worked well but my router at work just wouldn't hold the connection.
I was about to give up and go back to HC.
I thought I'd give the new Austrian build a chance LQ2.
Since changing I noticed better Wifi signal for starters and no drop off like the Hong Kong version.
They Wifi seems fixed on the LQ2 build, it's working very well so far.

Cricket Fascinate JB

I have been running ICS on my fassy flashed to Cricket and used the Alt Carrier Fix. Everything but sending MMS worked fine.
I just flashed the latest AOSP JB ROM and 3G keeps trying to connect but wont. Just like ICS did before I flashed the Alt Carrier Fix... So I flashed the ICS Alt Carrier Fix but it did not work. I figured it was a 50/50 chance it would work. So basically it does not work with JB. Any one know if there is a JB Alt Carrier Fix or if APN's are able to be edited in JB?
Need to get my data working.
**UPDATE**
JB Data Fix is posted in post # 4

Hey did you ever find a fix for this? If not, there's a data fix zip on the cricket users forum website just look under the fascinate thread. It worked for me, AOKP ICS Build 32 but also works for JB roms

No I havent.
I tried that with JB and it never worked.

Ok I found a JB 3G data fix. Can confirm it works with Cricket.
I do not take credit for this. I found it on cricket users and the person who posted it there didnt know who he/she made it either. I think it says who the author is when the flash finishes but I can not remember.
3G connects much faster than the ICS data fix did. 3G was connected as soon as I booted to the lock screen.
enjoy!

[Q] US Cellular jflteusc SCH-R970 CyanogenMod Nightly MMS

I flashed my US Cellular Samsung Galaxy S4 a while back with CyanogenMod 10.1 and everything worked fine. A few days ago I updated to 10.2 and everything worked except MMS. I cannot send or receive MMS. I have been searching through forums, google and have not found the answer on my own so I am asking for help. I updated to the lastest nightly hoping it would fix it but no.. Some say its the APN some say its a google issue. I looked for the 10.1 I have before but it seems to be dropped on cyanogenmod's site and no nandroid backup How can I fix this?

Have you set up the APN to what your stock APN would be.most of the time anything to do with service would be APN issue. You didn't mention you tried the APN is why I asked
Sent from my ATT S4 MF3 using Tapatalk

I have tired editing the APN when I save it, it disappears. I try to open a new one then save it, it disappears. In comparing what others have posted for LTE mine is different but cannot find a flash to is in clockworksmod. I have lost 4g/3g with the latest nightly, I installed from a clean flash I do not like doing the dirty flashes.

(Q) unstable wifi on nexus 7 2012

Hi all, couple days before my nexus suddenly have an unstable wifi. It never been this before and it getting worse. Im using the latest purity rom with lean kernel.
I ve tried to factory reset and flash again with the same rom with the same kernel, but it only last for an our than it started unstable again. I reset it my router and my modem but no luck still unstable. But my other phone vs980 work fine.
I have read other topic about this matter and tried to install some of the apps but still does not work.
Is there any rom and kernel that might fix this problem. I am playing online game and it is very annoying to have this problem.
Pleasee help and thanks in advance.

I'm also having this same problem. It seems to have just started out of the blue. I thought it may have been rom related so I flashed a different rom (PA) but I'm still having this problem. I'll report back if I can find anything out. Or if anyone knows the cause or fix for this, that information would be greatly appreciated.

Just now i ve tried cm11 official and it seem the problem still there so i restore my backup and it work fine i think, but stock rom without any modified kernel is so lagging. So i return to purity rom. At first, wifi has stable connection but after that same problem occure.
Please someone advise me what to do .. please.
Do the f2fs fix this problem.
Thanks again and sory for my bad english

Bump
I've done a lot of searching and this seems to be a problem that quite a few people seem to be having, but I haven't come across any solutions. There were mentions of using a Wifi fixer app from the play store but that proved ineffective. Any one else running into this problem?

Same problem here.

I ve tried return to stock again with my backup and did not last for long because to laggy and i flash f2fs lego kernel with purity rom. And then the nightmare came back damnnn. Its is bizzare because a month before ot works just fine with the wifi. Probably with the apps or the router is not compatible . And the worst part, that ive got buffering when watching youtube from the first i had this nexus.
I think the best solution is wait for 4.4.3 to release.
