Good Day all

I was wondering if someone could assist me in an network solution.

Equipment
PC with GB port ( acting as Media Server )
Netgear GS724T-300EUS
2x+ Mikrotik RB951G-2HND
P5100 Samsung Tab 2 + Samsung Galaxy Nexus I9250

Problem:
I would like to do multiple video streaming to multiple devices via wired or wireless streaming.
Now streaming wirelessly works if one it closely placed to one RB, but if one moves away one get dropping of streaming.
I tried setting the SSID to the same + TX power to 21dbm + Channel

Current Setup
PC connected to Netgear, 1st RB951G connected to Netgear on Port 2 ( Using a 3G Modem to dial PPP connection, sharing the internet connection wireless and lan... DHCP Server set up on the 1st RB with Statics marked so I can do Internet Firewall ( enable/disable ) internet access). The 2nd RB951G is connected on 1st RB951G port 5 and powers the 2nd RB via POE.

On the 2nd RB951 I setup DHCP client.

What am I missing on...

Would love some guidance if anyone could spare.

I am guessing you have all the same settings, security type, passwords on both devices. If you disable the primary working wlan, can you sucessfully connect to the second devices wlan?
