WDS how I use bridge wifi signal

works really great to other router is at my grandma 4 houses away from mine router with the DSL signal works great both of them have MAC filter so only register devices works with them !!! i can ever send my internet to any router over my range but i have no idea if i send mine internet signal to other router with internet will improve speed or will have some conflict !

If i put my router in Universal repeator mode will also serve me in running net and will work as a range expendar to other wifi device or laptops ....Also tell me is it possible that i want to run my net from acess point no1 as im in client mode but my scan list show 3 acess point i want to forward the range of another 1 of the 2 acess point ... How to do this ? I use TP LINK WA-501G And my friend has TP LINK WA-500G
