Question: I already own one. I want to put another one downstairs for gaming setup will the wifi extend even more if i have two?
Document: The setup wizard (when it fails to connect with MAC filtering enabled on the router) will show you the THREE MAC addresses you need to add. Again, one is not listed on the tag underneath the device and there is no way to get it other than through the setup wizard or by disabling MAC filtering and taking a peek at your attached devices. But even after you add those three, you still have to redo the ones you have already if you want them to ever connect through your router.
It gives you a 2.4GHz, and a 5GHz wifi line that you can combine into one for super high speed but I am not able to test that because my wifi is fast already when it comes to gaming. I was interested in the extended range. Four stars because I figured it would be farther than 15 steps. In reality if it is for rooms of  you house that doesn't get good coverage this should do the trick.
The first one I ordered could not connect to my router even with the help of Netgear support. They suggested that I return the unit and get another one which I did. The WPS method of connecting did not work so I connected manually. I was able to connect to the 2 GHz band and placed the extender 75 feet from my wireless router with no walls obstructing line of sight. I was trying to get the signal to a guest house 100 ft away with two walls between the extender and my computer.
I'm kind of having a hard time writing this review because I don't want to be really negative and I have a lot of challenges as far as networking but...For the impatient, the bottom line is that it increased the signal power by one bar. So yes, it did improve the wifi signal, but not by a huge amount.The problem may be that I live in a two-story log home.
I thought I finally found the solution to my problems with this unit and the great reviews . However I could never get the unit to work , horrible set up instructions and support from NetGear e.g I was put on hold for long periods of time and they would disconnect after or while talking to you , after  4 x I know that was intentional . Net support page they give you is not even active , I am returning and never buying another item from them .
I brought this product to extend my home WiFi converge. Had it for 2 weeks and i have to say its almost perfect, well ~ Almost.It's super fast, got excellent WiFi coverage, exactly what i want at first place. However last week when i play MOBA game, i find a small problem. Extended WiFi will disconnect from internet periodically. In fact, this issue is hardly noticeable in normal internet activity like view web page, watch video or download file.
This one is hard to review for me. I know very little about technology and its enhancements. I just took it out of the box and followed the instructions. Not hard to do and it took under five minutes. But does it extend my network? I did a little experiment. Before hookup I walked outside my house because I have a small house and every room already gets five bars. After 50 feet my network drops outside my brick house to one bar.
My cable home automation company recommended Netgear to me to help extend the wireless service in my three story house. My cable company had already installed the Netgear router and modem. I don't know if there were too many dueling Netgear signals or not but it only worked for one day. Afterwards I couldn't connect to the internet. When I did the troubleshooting, it said that the router had the wrong IP address. Netgear support told me to update the driver on the extender.
Even in the yardI have a solid four bars on my iPhone when before I had one. The extender really is noticeable, and it's a solid signal that holds.As I said before, this extender just works. It's easy to set up, looks sleek, and performs its job well. What more could you want?
I love being outside in the summer. However, I also love streaming music and movies. For a long time, I was unable to mix these two loves since my wifi range did not reach past our back door.Enter this awesome Range Extender.! I put it on top of my fridge and now I'm streaming music through my ipod while doing yardwork. I'm watching movies on my tablet from a lawn chair under my favorite tree.The extender was amazingly simple to set up and it works fantastic!
Answer: Hi Brian, you can use two extenders in one network, but you won't be able to "chain" two of them together to further extend the signal. If you're having trouble getting signal downstairs even with an extender, you might want to look into a Powerline setup!
