You need to disable TKIP and use AES as the only encryption method.

TKIP doesn't support 802.11n or 802.11ac.

but still I getting max 70 mbps speed, any other way to increase the speed ?

Is 70Mbps what the NIC tells you you're connected at, or what you get while doing a speed test?
are your devies connecting at 5 or 2.4?
