This guide has been tested using the MR814 v3 router and the MA111 reciever. If you arnt using these versions, I cant guarentee that this guide will work for you. It wrote this tutorial to help those that cant seem to get it down.

Before you set it up, your modem sould look like this: (sorry for the crappy pic im using a mousepad)
Unplug both the input ad output of the modem. Plug in the cord that was in the input jack in the modem into the input jack in the router. Plug in the output into the output in the router. It should now, look like this:
Step 2 - Intalling the reciever
I cant really help you with this it all depends on the reciever you bought but generally you plug it in and run the disk that came with it. If not, read the manual! Its amazing how many people throw the instruction manual away and wing it. If you are not experiance, wingin' it will produce bad results.
Step 3 - Done!
You should be ready to go. If it doesent work, Cheak the box and see if it has a NAT firewall, Goto step 4. If it does not, still goto step 4, but it might not work.
Step 4 - Setting up the IP and DNS
Goto the computer with the router and press start, goto connect to, and press all connections. Right click on Local Area Network, and hit status, and click the support tab, and click details... Write down the IP, subnet mask, deafalt gateway, and DNS server. Goto the computer with the reciever and click start, connect to, all connections, right click wireless network connection, and press properties. You should see some items in a list. Double click on internet protocol. Type in the information you wrote down. Click ok. Your done.
