Netgear had issues from the set up.  I called for support and nothing could be done to resolve this problem.  So I returned it.

Set up took 2 calls to Netgear. It would not link to my router. Once linked, it lost its signal once moved away from router, so we started over. A new style is suggested as little antennas are a target for toddlers. Once set up it works great!

I got it plugged it in followed the directions and it worked. One thing that made it easier is that my router is also a Netgear.

Did not work well, I contacted Netgear only to find out that to extend my Netgear router (N600), I needed a N600 extender --- NOWHERE is this stated in the sales literature or in the Amazon add. Buyer Beware !!!!!

I am still using my old Netgear Router. It turned out to be ok, just not turned on. I have not returned the new router.

I am technically challenged ~~ a friend installed the Netgear player, along with other devices. I am slowly trying to conquer the instructions. My problem is understanding Netgear Technical support people. I was barely able to register the device , and they were trying to sell me $$$ other support services. I paid $39 and now the price is well over $100.

I've used Netgear products for nearly all of my wireless needs in the past, and this is the first time  I've ever had an issue. Unfortunately, the service agent I spoke with was singularly unhelpful. She stated she knew what the problem was, and how to fix it that second. I would have to pay an additional large fee to get it fixed though. When I told her that I didn't wish to pay without trying out any other options, she suggested that I call back (and pay)  if i couldn't figure it out myself. Sadly, my unit still isn't working, and I'll likely have to return it. I wish I could report on how well the product did or didn't work.

Router randomly reboots when connecting WiFi devices to it. Not worth trying. Netgear has replaced the device once, and I spent 2 hours on the phone with tech support - they have no idea what's going on. Seems to be a common issue based on forum posts: when you connect or disconnect WiFi devices, the router will randomly reboot, disconnect all devices, and force you to reconfigure the network connection again. Very frustrating. Avoid.

After numerous hrs on phone with both Centurylink and netgear I finally gave up and had to return the router. Centurylink said the router was interfering with their modem and Netgear had to fix it. Netgear twice downloaded the same firmware I had already downloaded, assured me the problem was addressed but nothing really changed. At least once a day I had to reboot both the modem and router. And router always had to be rebooted after modem or it wouldn't come up.

I am also an IT Professional that ended up with a stack of failed units and NetGear not offering any real assistance other than posting my concerns to a web based support system, and waiting a day for response, we have been going back and forth for 2 months.  I had to rip these out and replace with equipment from another vendor.  Totally disappointed with this product and Netgear's response to concerns.

I find this router is incredibly hard to set up. It kept telling me I have static IP. Choosing dynamic IP would not connect either. I have a comcast connection in San Francisco, my current netgear router works just fine but I wanted something newer for an apartment setting. I have spent total 3 hours trying to set it up, no luck. So far, WORST experience on this product. Tried calling customer service number, voice mail box is full and no one ever answered that damn phone. How is the set up straightforward? I bought it early Jan and still laid there not usable. Am I missing something?

Well, the wall adapter literally began to melt.  I'm seeing how Netgear's CS resolves it before assigning a final score, but it's not an ideal situation.  In the few minutes it worked, it was easy to set up and worked well.  Startup/reboot was slower than I expected given the processor.

Working so far...after spending two hours with Netgear tech support. Dont let the easy setup fool you...its not easy. The device requires special settings for smart TVs(Samsung) and other smart devices, Wemo, Nest, etc.

I bought this on Amazon to replace a Netgear modem. There have been repeated issues within a very short period of time. Wifi frequently drops needing a modem reset, and Cox tells me there is a hardware problem.

Original Post in June

I have both Netgear router 3700 and this extender. But the Extender would not connect to my existing Wifi network. I called the customer service number, after 50 minutes on the call, they got it work. However I have to lower the security protocal to the lowest type - WPS. I was told that there is configuration issue with my Netgear Router which I purchased three years ago and has passed warranty period. So my choice is either return it or pay extra to talk to a Netgear technician to fix my router.

So be aware if you have an older router, even if it is from Netgear too.

Follow-up on 7/14

After my original post, NetGear quickly contacted me by both email me and had an customer service engineer call me. They informed me that they should work with the higher security protocal and they offered to help me set up. I managed to changed it myself and happily report that now the extender does work at the higher protocal of WPA level.

Now I have another issue - I upgraded my Comcast Cable Internet to the 50MPS and I do get that speed while connecting to my original router. However the speed of connection from the Extender is only between 10 to 14 mps. I am not sure what is the reason.

I am changing the evaluation from two Stars to Three stars for the great customer service and follow-up from NetGear team and I hope they can help me to fix the problem with the slow connection.

Wireless speed was very slow compared to the unit it replaced and after several hours on the phone with Netgear tech support we were unable to get Port Forwarding to work. The tech support group finally said it must be something else happening and I should call someone else. When I asked them who should be called, they had no idea.
