I have used this antenna to extend the Nevo Connect's antenna and it has cured a few connectivity issues. Nevo also has an extender available, but you have to get it from a Nevo dealer.
[Link: dlink.com]Message me if you need additional help, I am in Phoenix.
It just hit me that I hope I wasn't the installer who went MIA......
Probably not, I think I have only pissed off a couple of people lately. Let me know if I can help.
