[Q] Custom JVS ROM (2.3.5) Wifi Hotspot

Hey guys, recently I have been trying a custom ROM called Doctorz Rom v2.0 based on JVS 2.3.5, it was pretty good, stable but had to fix some glitches myself.
To my dismay, I switched on the Mobile AP, some call it wireless tethering or just wifi hotspot, and there was an error. I could still connect other device like my mother's LG Optimus 7 to my phone but it couldn't connect to the internet.
I did a search on google and there seem to some issues with the wifi hotspot with custom ROM, well there are a handful who are on the stock JVS rom and it worked out well. I have used this mobile AP in 2.1, 2.2, 2.2.1 and 2.3.3 and it all works fine except on this Doctorz ROM based on 2.3.5.
Just a check if anyone who is on custom JVS 2.3.5 ROM, ODEX or DE-ODEX, is also having an error with the mobile AP or anyone who is on stock 2.3.5 JVS ROM with fully functioning mobile AP.
Thanks in advance

Wifi problem in JB and ICS roms!

I currently have 2.3.6 GB on my phone(I9000) with this I can use hidden Wifi networks! But ICS and JB roms I cannot use hidden Wifi networks, they always stop at authentication and give authentication error, normal Wifi networks work perfectly. My friend has ICS on his Galaxy S III and he can use this hidden Wifi. What can be the problem?

for ics: SLIMICS
