Mini Sub-Station

Hello,

i am using a grid and setting is this.

 1  R name="Grid" mtu=1500 mac-address=00:20:E0:1A:1E:67 arp=enabled 
      interface-type=Atheros AR5213 mode=ap-bridge ssid="Grid 1" 
      frequency=2437 band=2.4ghz-b scan-list=default antenna-mode=ant-a 
      wds-mode=disabled wds-default-bridge=none wds-ignore-ssid=no 
      default-authentication=yes default-forwarding=yes default-ap-tx-limit=0 
      default-client-tx-limit=0 hide-ssid=no security-profile=default 
      compression=no

Now i want to put another grid on tplink 5110g to receive this signal and then repeat the signals with the help of another tplink 5110g both are connected with lan with each other. i am using Omni on 2nd TPlink for transmitting signals. In short i want to make a station.

When i connect 1st tplink 5110g as a client to main its connected and working fine but internet speed is very slow. 2nd Device is working as Access Point with Dynamic ip getting from 1st device.

My questions are and i want following solutions:

1- I want to do this good internet speed. Can you suggest me 1st device and 2nd device mode.

2- I want to show client Mac address in mikrotik also with his/her device mac address.(Now i am getting only connected device 1 access point and my users connected to device1 mac address.)

Please tell me briefly.

Deadly waiting for answer..
