I have a Netgear nighthawk x4 that I would like to use as a range extender/repeater/Access Point. I have xfinity triple play in the house, and it's perfectly fine, but I have an attached guest house that I rent out to students because I remember how hard it was to make rent while going to school full-time. I want to extend my home internet out to the guest house, which is maybe 300 ft. from the main router. Before switching to comcast and xfinity, I was using a NetGear Nighthawk X4, which was a good router at the time, but it's no longer needed for the house. I've read that you can set it up to extend your wireless range if it's placed near the boundary of the wireless signal and if it's configured correctly.
I'm asking for help in setting this up. I have contacted my provider (pointless) as well as netgear (the router is out of warranty), and the kind rep. at Netgear pointed me to this guide (http://kb.netgear.com/24104/How-do-I-change-my-Nighthawk-router-to-AP-mode-after-I-ve-already-run-setup) but she couldn't walk me through it. I'm clearly not following the directions correctly because I keep coming up with no connection through the nighthawk even when connected with a direct wired connection.
I would appreciate it if anyone could offer me suggestions on where I might be doing something wrong, or they could walk me though the process. I know I could just go out and buy a new range extender, but I'd really prefer to make this one work for them, because I think that once it's set up correctly it will do a much better job than a $35 range extender. Help?
