LACK basic features to use the current wifi and extend it.

This product basically creates a new ssid that you have to connect to when you are out of range of your current wifi.  I didn't like that I have to enter a new password for each of my device.  The biggest problem is if you have MAC filtering you will need to add the translated mac address for each of your device to your MAC TABLE.  I have over 40 devices plus the original MAC that is 80 entries in to my MAC table.  NO THANKS.

Pros:
Great improvement from previous PX version, more :hi-fi: sound wise.
Better logarithm on auto EQ and anti-feedback, more efficient.

Cons:
Lack Wifi capability therefore a false pretense that you can use a tablet to control it in a public venue.  Must have network ethernet connection to be seen by a tablet...kind of rare in most public venues.
Computer or tablet Interface is ok but lacks clear functionality on how to download various speakers specs. configuration from internet.
Way too expensive

I purchased this to extend my current house Wi-Fi signal out to my workshop remote from the house, it does the job, but by adding another Wi-Fi connection which was not clear to me on purchasing it. This means as you move around with mobile devices they will need to log on and off the main and extended wi-fi connections. It requires to be in range of the existing Wi-Fi to pick up input, which means a Wi-Fi crossover zone and now my laptop in the house seems to pick up and log on to the extended Wi-Fi connection even though it has the weaker signal in the house.

I contacted Netgear Tech support, but their answers were basic and of no help whatsoever.

For my application a true repeater that just extended the existing Wi-Fi would have been better and a lot less hassle, that's what I thought I had purchased, so beware.

It works ok using the wifi extender feature, but often fail when using the ethernet wire port, because anything a connecte to it get disconnect frequently

There is no way to do wireless internet connection without buying a wireless adapter.

We got this to expand our Wi-Fi and it didn't really help. Will probably send back. Good luck if you get it.

Like other users confirmed, unless u hook up directly ethernet cable, the wifi connection is rather very dispointing. Returned it and now waiting for fire tv.

you cant really do anything unless you have a WiFi connection .. it is difficult even to use it for a given app which does not need a wifi connection [which is how i use it] .. i have a dirt cheap internet usb hi-speed wireless dongle which i use for the internet .. no wifi .. so it makes this very difficult to usein general  .. even the user manual is only available if you have wifi active .. for some unfathomable reason, this is NOT downloaded for local access .. so to be really useful in general, this should be made much LESS wifi dependant

It needs to position where there is good signal to extend range, otherwise, it is not going to work that well.  Easy setup though.

Its useless and doesn't connect or help with any wifi enhancement.  Even after being on the phone with the netgear tech, I was told it doesn't allow any extension of the existing wifi.

The up scaling is wonderful.  The build-in wifi is horrible/useless.  The Internet only works if it is wired in.

The WiFi range is way less than my old LinkSys wireless router, it will not reach my TV in the basement. I called customer service twice, they were of marginal help, but offered more complete service for $30, really on a product less than 2 weeks old! The guest sign in feature is available if I sign up for the extra cost help.
If it were not for all the change-over trouble, I'd send it back.

I don't know why I'm willing to waste more of my time on anything that relates to this router... Set up is easy. Signal is worthless. You would have to be almost standing on top of it to use wi-fi.

Have to use a different SSID which makes it useless as an extender.

the wifi range is really good, but the internet slows waaaayyyy down when you are using it, I try to never use it if I don't have to.  Too much lag time with the internet connection when using this range extender.

It would have been nice if they had sent me one that would actually work with wifi.  It's completely useless.

My wifi was about 25mb/10mb with original router. Now with this is barely 5mb/1mb. What's the point of extending the range if it's not even enough to play YouTube videos.
