So I set up a hotspot using hostapd, isc-dhcp-server and MASQUERADING.
The hotspot works and I can access Internet.
Problem
The connection speed is too slow.
When I connect to my hotspot (via android 4.1, Snapdragon S3), I see a connection speed of 65mbps, which drops down to 1mbps in seconds.
I know this isn't a hardware issue as I can easily get 24mbps (54mbps link) out of my ethernet connection on Windows (via connectify).

What I have tried:

prakhar@pr3d4tOr:~$ sudo iwconfig mon.wlan0 rate autoDisable power management:
prakhar@pr3d4tOr:~$ sudo iwconfig mon.wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device mon.wlan0 ; Invalid argument.
I tried the above for wlan0 as well. No results. Can anyone guide as to what might be the problem?
