My house is hard wired with Cat5 all over and I have a centralized router etc.  I am wondering if there is a product available that I could plug into any network wall jack that would then create a wireless connection with a single computer.  In my case it would be a laptop.  Essentially, I just want to replace the wall to computer connection with a wireless one.  I do not want to setup a wireless network or anything like that.  I just want something that functions just like a cabled connection without the cable.  I picture a transmitter/receiver that plugs into wall jack and then another that plugs into computer.  If someone can point me in the right direction I would very much appreciate it.  Thanks.

Huh? You want to "replace the wall to computer connection" but you "picture a ....... that "plugs into wall ..... that plugs into computer?" AND , lol, you , "want to replace the wall to computer connection with a wireless one," but you "do not want to setup a wireless network or anything like that."

Here's what you need dude.

Ya, I think I know exactly what he's asking as I did the same thing..  Basically it's a wireless network and a wired network that talks to each other where all devices start with the same IP address (ie: 192.168.0.XXX) instead of splitting them into different network segments (192.168.0.1 and 192.168.1.1)

Any wireless router will work, just plug the connection to your wired network into any regular port in the wireless router/access point except for the WAN/Internet port (do not use this port!)..  configure the wireless router and disable NAT and DHCP..  Enable WPA2+AES encryption, have the laptop connect to the wireless router using your key (it will show up in the wireless network browser)..

Then it should just work..  If you don't share your WPA2/AES key, then nobody can connect to the network except for that laptop and the wireless and wired will communicate back and forth, but all be on the same network segment.

I think what he was getting at as far as not creating another network is that he didn't want a cascaded network where his laptop would be connecting to the router on an IP address assigned by the wireless router ..  You can connect wireless and wired networks without cascading/multiple network segments by just disabling most of the wireless router's functions like NAT and DHCP... Then the wireless router just works as a dumb wireless access point that you can connect to, to get onto the wired network (IP address from wired network's router instead of from the wireless router)...    In most cases, that way is better since all your network devices wlil be on the same network segment (192.168.0.XXX) instead of having wired on (192.168.0.XXX) and the wireless devices on (192.168.1.XXX).. .

Also, port forwarding to your wireless devices will be much easier since you'll only have to forward once instead of twice (forwarding to the wireless router and then have the wireless router forward to the wireless device).

What's needed is a small-sized access point, preferably with power over Ethernet.   Just browse wireless access points in networking section.   Set the AP to work in AP mode (some can also work as a router), configure a wireless wiith WPA2/AES and SSID broadcast disable.    Some APs also support MAC filtering - so you can make it truly single user.    Once that done, you should be all set.   This is likely to be the cheapest and most convenient solution you can find.
