Vido mini 3G tablet help

Hi clever android folks


needing some help..


I buy a year ago from dx.com a tablet called Vido mini 3G,,, its been really good tablet once I got it rooted and
xposed added etc

but this week I decide to try its hotspot feature since our home wan went down and had to switch to 3g and
wanted to share same SIM card data package with other devices like win8 and other androids

the hotspot aka wifi tethering just fails. it connects but stuck on obtaining ip and if manually give a ip it says connects
but no throughput happens.

has anyone got one of these tablets with JB 4.2.2 image from 20131119

and had same problem and found a solution

i suspect kernel or firmware issue.. like bad wlan driver??

the USB tethering works fine though

or better still is there a custom rom for this model I see a few for kitkat for vido N70 but I dont think its
the same hardware.
