Wifi and wired routers together?

I am currently using Linksys BEFSR41 ver. 2 wired router. I am using 3 of the 4 ports available. I want to get an inexpensive WIFI router or device such that I can get a wireless signal to a building 150 feet away. I'd like to keep the wired and add wireless. Any suggestions for Hardware and how to do this?

Sorry, I wanted to post this on the how to forum but it denied me.

Pair of $49 Ubiquiti Loco M2 radios.

A Pair? meaning I will need two of these kits? $49x2=$100

Can a wired and wireless router operate at the same time from a cable modem?

Well...Just get one. See if the Linksys gets outside of the building. If it doesn't, you 'll have to place an AP on the outside.

Each router can share the same the LAN side of the cable modem, but you'll have two separate subnets that can't talk to each other.

The solution is to have the wireless router act as a bridge.
1) Turn off DHCP server.
2) Set the LAN side to same subnet as the wired router's LAN.
3) Don't plug anything into the wireless router's WAN (might be labeled "Internet") port.
4) Connect one of the wired router's LAN ports to one of the wireless router's LAN ports.

Just before your post I went to Best Buy and bought a Netgear N600 duel band router. Its nice because I can retain my wired connection and add a wireless connection. Not sure if this is the best way to go.

Tonight when testing the wireless, the strong signal drops off outside and does not make it to my objective building 150' away. Thinking of trying that Loco M2 as a range extender. Comments?

I have an open Ethernet port on the Netgear v600. Is there a reliable way to run a wired Ethernet cable 200 feet?
