[Help & Temporarily fix]can't use wifi / usb / bluetooth tethering when data is on

[Help & Temporarily fix]can't use wifi / usb / bluetooth tethering when data is on
hi
I have this problem for a long time but i found some new things about this problem that want to share it with everyone , so i decide to create a new thread , so you can share your ideas to fix it also i found a way to use it Temporarily
my device info:
lt18i , android 4.0.4 , build number 4.1.B.1.13
rooted , bootloader unlocked
installed UHDv4 ROM and UHDv4.8 MOD with LuPuSv16
who have this problem ?????
my problem is :
i want to use (wifi/usb/bluetooth) tethering , everything is good just after removing wifi modules from lupus menu ( just for a minute )
after a while i can't use wifi tethering when data is enabled
*****The only thing that I did not notice, it was option 3 , you will read it in the following*****
so i decide to use another kernel : so i should to flash a wifi module from CWM but after boot up i don't have any wifi but (usb/bluetooth) tethering works good
i also tried to remove lupus wifi modules before flashing new kernel
So I went back to LuPuS
***** i found a new feature i should do the following to make wifi hotspot works when data is enabled ******
i have 3 options:
1 = first enable data then enable wifi hotspot ***in other words*** enable wifi hotspot when data is enabled = works
2 = first enable wifi hotspot then enable data ***in other words*** enable data when wifi hotspot is enabled = this will make the problem
i should just do option 1 to make it work , if i do option 2 , the problem starts and i can't make it work with option 1
after that the problem starts :d i can't use it again to solv the problem , for example
but i found a new option for make it work
3 = enable data then reboot ***in other words*** reboot when data is enabled , without removing wifi modules
if i do option 3 , i can use option 1 again without problem
uuuhhhhhh so strange problem
i think my phone have problem with set the internet ip address for tethering
here is the logcat when i did option 2 and wifi hotspot don't work with option 1 :

finaly the problem is fixed now
hi
finaly the problem is fixed now
you can't solv it by changing a rom or kernel , you should flash a FTF with flashtool to solv it
here is what i did :
i flashed LT18i_4.1.B.1.13_Vodafone DE.ftf with flashtool and it works now
after that i flashed LuPuS kernel and UHD ROM and UHD MOD
it is still works very good , now i can turn on wifi hotspot when data is enabled whithout any problem , everything is good now
i suggest you flash LT18i_4.1.B.1.13_Vodafone DE.ftf For increasing system and data memory for Arc user and latest BB

Hi I think I find how to fix it
You can flash a ftf via flashtool to fix it but this way will wipe all your data
we can flash a ftf but without flashing system, kernel, baseband and without wipe data
You can choose which one you want to flash
So select what you don't want and leave unselected which you want in flashtool

hi EAGLEBOOY,
I have moved your thread from General section to Q&A, Help & Troubleshooting section. This maybe useful to others so if it is in Q&A it will be easier to find. Please use the correct sub-forums when posting.

[Q] wifi hotspot problem

hi, first sorry for my very bad english
yesterday i have flashed my htc desire first time with the latest evervolv rom (evervolv.com/devices/bravo) and all works fine, but i have a problem with wifi hotspot / tethering.
i started a hotspot with wpa2 password but no device (2 Laptops (win7 / 8) and a Galaxy s2 (cm 11)) can connect to the hotspot. they are in the connection loop. same with wpa key. but if i running the hotspot at open without a password, all devices can connect succesful
is this a known issue? hav everyone a idea what i can do? thx
best regards

no one has a idea?
I flashed some other KitKat Rom´s and by all i have the same problem.
Now i flashed a ICS Rom and Wifi Hotspot works great with WPA or WPA2 Password.
But i would love to run the Hotspot with a KitKat rom.
Wifi Hotspot works on your Desire with KitKat rom and WPA or WPA2 Password or you guys have the same issue?
I would be glad, if anyone can help me.
Best regards

There is a search box forum. For example, type "hotspot problem," then you will find the answer.

shareIt app not working on cm12 or any 5.1.1 rom

When I use share it the WiFi do not turn on automatically and after closing the app WiFi is disabled and I have to reboot the device to enable WiFi. Any fix

@deep54671 yes I faced the same problem with cm,aicp. I wrote for this issu in cm12.1 thread, but no one can solve this problem. It happens when hotspot open for 2 times,after then wifi doesn't work.

Go for the cm12.1 new update-2015115. Shareit work perfect in this rom and I did not face any issue with this rom highly recommend to everyone...

if you are using the Exynos J2, then LOS14 is still in development stage, and therefore, bugs.
You should report the bug(s) there instead.
