In my office I have a wireless Cisco Linksys EA4500 router, it has 4x wired ports (which are all in-use right now). Now across the house I have setup some HW that requires 4x wired RJ-45 connections (the hardware is not WIFI ready) so I see 2 simple solutions:
1- Buy 2x switches one to free up a port on my wireless router then run an RJ45 across the house and setup another switch there, costly and got to make some holes
2- Buy RJ-45 to WIFI adapters for each box ($40+ each) which is again costly

I am looking for an affordable solution to my network woe?s?

What I thought ? can?t I buy a 4-port wireless SWITCH or ROUTER to act as a repeater in the room (so WIFI connect to my wireless router) and connect my 4-devices physically to the box? If so are there cheap boxes that can do this?

If not ? any suggestions?
Thanks,
