Question: How does this work? Do I just replace the current wireless DSL router from the phone company with this one? Does it really make the connectivity faster? We stream movies, have iPhones and iPads, and Mac.
Document: I have really love this unit, Mac and Windows are easly setup to use WirelessOne draw back I do have i my old 2Wire Router for DSL , does not like to share with Airport, but I just have DMZ Mode setup on the 2Wire Router to the Airport and I get great speeds and connectivity on all my wireless devices.
I work at an architecture firm with around 20 employees. We recently had problems with our wireless access point so instead of having our expensive IT guy come out I purchased one of these. Set up was really easy and we've had zero problems since we started using it. The speed is blazing fast, especially for newer iPhones and iPads that support the newer protocols. I would definitely recommend this.
This is a great router with lots of options, while allowing it to be set up simply. I use this at a small business, and the dual radio setup really is great. With this one wireless router we have a protected company network access point and a guest access point. They both have separate passwords and the guest access is completely separate from our company network. The new faster radio is blazing fast as well. Great router and rock-solid performance!
Unless your a router geek -- you'll need an apple router to make your Mac work with your Apple TV and any other blue tooth / wireless devices. I had a different wireless router N class that worked well for myself, my wife and kids throughout our home. However, we really enjoy playing music on our home system which has multiple zones throughout the house including outside.
I bought my first unit to provide dual band WiFi that my phone company provided Motorola 3347 DSL router doesn't do. I have some congestion on the 2.4GHz band in my neighborhood and I also wanted the higher speeds a 802.11n compatible device would provide to my iPhone 5S and iPad Air on the 5GHz bands.
Performs 3x faster than cable provider modem/router. Great product. Make sure you have cable provider tech support on the phone to assist in turning off wireless function on their modem/router. This will maximize your AirPort Extreme's wireless throughput.
I bought this to replace the router component of a Comcast all-in-one that was dropping connections to my linux work laptop regularly. No such issues with this router, and of course it works fine with my Macbook as well. Heed the warnings on opening the box - this is some of worst packaging design I've seen from Apple. It's almost designed to make the router drop out of the box.
I love this router, and won't ever be going back to another company. I am a big Mac fan, but my switch to the Airport Extreme 5th Generation (one before this model) came after SEVERAL headaches with my latest, greatest Linksys router a few years ago. Right when wireless N technology was coming out, I got a nice shiny new Linksys router, and although it did put out a great signal, that was only when it wasn't failing to connect.
I bought this router to replace a netgear that had many problems and terrible range. The AirPort Extreme is by far the much better router. I have iPads, iPods, iPhones, pc's and android phones in the house and I have not had any issues with this router. Setup was so simple that it only took 15 minutes using my iPhone. I definitely recommend the AirPort Extreme for ease of setup, range and functionality.
I needed a new router that would be both faster and reach more areas of my house. I hadn't considered this brand until going to a retail store and an associate recommended it. I already have iPads and iPhones I just hadn't thought about an Apple router. After reading the reviews I decided to go forward with the purchase and have been very happy.The setup is super easy.
Answer: Jura re-read your question.  You could disable the wireless signal, on the phone companies router.  Connect an Ethernet cable to one of the LAN ports (on the DSL model) and set up your own network.   You can also use the AirPort Extreme in Bridge mode to extend your network.   This means that the DSL wireless router will still be the main network and you are now extending it to other parts of the house.   Nice thing about the AirPort Extreme is that if you change internet providers, you can host your own network. I switched from DSL (barely getting 12 Mbps down and 1.5 up) to Cable (52 Mbps down and 11 up)
