This unit take care of all my internet and wifi needs , have as many as 6 to 7 different items on line all the time, no problem at all for the last 7 yearsWanted an AC router, did lots of research including DLink, Netgear Nighthawk, and Asus high end routers. Liked the concept of this router's SmartLink interface. There were lots of bad reviews but also some good ones too and figured I'd try it out, worst case I could return it. Bought in June 2014. Day 1, setup was easy, range was great. 3 hours later while streaming the signal was gone. For 2 days this occurred anywhere from 3 -7 times per day. Pulling the power seemed to fix it but a $180 router shouldn't need to be rebooted (ever in my opinion) much less 3x-7x per day.Call 1:So I call Linksys/Belkin (well armed with how the experience might go after reading the reviews) to resolve the issue. I go through the motions of getting my contact info, explaining the problem and responding to their question path they read directly off a procedure list in front of them. Fine, maybe it will help. Verified that all the latest settings were enabled and that my router was properly configured, but they wanted me to re-clone the MAC address from a hard wire connection. Reboot and im back on my way after an entire hour on the phone.Call 2:Day 2, called again b/c of same issue, go through all of the same BS before despite having a case ID. I get a Sr. Technician finally who wanted to reset the router to factory and then re-establish settings. So night 2 after 1.5 hours of the same playbook of questions, the router is rebooted and works, for an hour before dropping both 2.4 and 5 GHz networks. Went to bed and decided to deal with the one last time the next evening.Call 3:Tried to reboot router first, that wouldn't work - no wireless internet could be achieved whatsoever despite it broadcasting the network name/signal. I was nice to the person who answered and said I know the router not working wasn't their fault but was out of patience, I want a Sr. Tech NOW. This person tries to run me through the same lineup of questions, I stop them in their tracks to state that my Sr. Tech last night said if I had issue again to ask for a Sr. Tech out of the gate. After 3 min of arguing I got a Sr Tech, explained the situation. He tried some settings an to no avail wireless internet could not be achieved. He sent me to customer service for a replacement. This all took about 25 minutes, best deal so far. Customer service gives me the option to ship back the defective item AT MY COST prior to the sending a new one or they would send a new one with a hold on my credit card until I returned the THREE DAY OLD defective unit back AT MY COST. I told the customer rep this policy of me paying to replace a new item was unacceptable and that I wanted a manager. Got a manager pretty quickly, expressed my issues and they finally agreed to pay the return shipping cost after 10 minutes of deliberation, and I was told that they could only do that once. (so, should I expect your replacement to be garbage too and have to pay my own way for sending that one back?!?). I also confronted the manager and last Sr. Tech to see if they were aware of the R6900 reviews out there and they said yes, but couldn't answer me what they were doing to fix it besides getting bad product returned to "investigate". At this point I had no plan to move forward since I could return it to Amazon and get my money back and buy another product that didn't have awful reviews.BOTTOM LINE - THIS THING WONT WORK RELIABLY, Linksys--> Belkin (no more good quality Cisco) customer service and policies are terrible and even if I got a working R6900 I would refuse to own a product from such a terribly run company. I can't say that DLINK or NetGear is better but at least their reviews are much better and it's worth a shot that their product will actually work. Don't order this part thinking you'll be a good statistic and it'll work for you. It probably wont and you too will invest 4+ annoying hours on the phone listening to scripted problem solving skills just to figure out it won't work. I have plenty of PC experience and dealing with networks and had two techs confirm I setup the router properly. To those at Linksys/Belkin: It's 2014, routers should work out of the box with minimal setup config and be reliable, at least for 1 month without requiring a reboot for a near $200 product. Please invest in some more engineers who know what they are doing and beef up your end of line testing for each unit. Unacceptable product.The short:Pros:- MEGA fast (connecting, streaming, transferring)- USB ports (with 1 supporting faster USB 3.0)- Powerful signal (no longer in competition with apartment complex neighbors--consistently strongest signal)- Sleek interface (easy setup, easy maintenance and setting changes)- Very convenient (Phone app allows remote support, meaning you can manage your router from anywhere)- Lots of functionality (client management, parental controls, media prioritization, NAS management)- Competitively priced- Aesthetically pleasing, much softer lighting than typical routers (esp. Linksys)Cons:- Mounting holes are in an odd spot (hangs router such that cables protrude to the left)- Power cable is a little shortFor reference I am on Charter (cable broadband like Comcast or Time Warner) with advertised 60 Mb/s. I live in a 2-level apartment with lots of 2.4 GHz noise from surrounding networks. We have the following wireless devices: 2 laptops, 2 desktops, 2 smartphones, Chromecast, and a game console. I used to also use a wireless range extender (TP-Link N300), however now I don't need it!The long:What a great router! I upgraded from an old Cisco N300 router that had done the job fine, but was beginning to need periodic resets in order to be functional. This combined with a shotty modem provided by my cable internet company and a range extender on another floor made for a frustrating dissatisfactory internet experience about 50% of the time. I upgraded to a new modem (Archer SURFBoard), and noticed the connection on wired devices was faster and more consistent, however my wireless signal was still spotty and intermittent especially with the noisy surrounding networks. I decided it was time to upgrade.I am definitely a techie so I did a lot of research before on different routers, and heard rave reviews from a relative and a coworker on the management app, signal strength, and overall router performance. The setup was super simple, just plug and play if you just want a router that works! The quick-start guide lists the pre-set strong password and unique SSID. I, however, had to make sure I knew every setting and feature well, and was very impressed with the settings for Media Prioritization (very useful for streaming) and External Storage (NAS, FTP server and user permissions!). I also set the wireless channel to 9 after bringing up a WiFi analyzing app on my phone and seeing that 1-6 or so were jam packed.The difference was, well, underwhelming! Before I was consistently annoyed, and now I hardly even notice it's there! The external storage is super useful if you haven't used that before. Me and my wife can transfer files between computers much faster now--our own personal cloud! I no longer use a range extender and I never lose connection.Overall, very pleased. Job well done, Linksys.P.S. My SSIDs: TellMyWiFiLoveHer and BillWiTheScienceFiI bought this to increase WAN/LAN traffic throughput, and it certainly achieved this goal - I'm now seeing 780Mbps download speed (speedtest.net) on my 1130 Mbps internet connection.The downside is that the management tools are very limited and clunky, and although it's possible to install other firmware, for example dd-wrt, it's hard to do.Very disappointed. I have received a 2nd hand Router. I ordered brand new but I received an open box. The box wasn’t sealed when I picked up, The router has finger marks no plastic cover, The cable is tangled, The antennas plastic cover are cut and opened.Muy estable no se desconecta en casi ningún momento, lo tengo montado en una base enfriadora de laptop ya que emite calor suficiente como para estar caliente todo el dia y noche, con la base enfriadora se mantiene al tacto a casi temperatura ambiente, quize ponerle un firmware anterior por estabilidad pero resulta que como este es la versión 2016 no se puede modificar el firmware; pero en este tiempo que lo he estado probando ha funcionado sin ninguna falla así que he visto que no ha sido necesario cambiar el firmware con el que viene integradoGreat router for the money, would like to see more intuitive and better security in terms of controlling the router as well as identifying and knowing what each feature specifically does for the lower and low end users.Está increíble este Modem para casas o para pequeñas oficinas, tiene un rango bastante amplio y la app ayuda mucho (me costó al inicio configurarla porque pide iniciar sesión en internet, así que eso deben hacerlo antes de configurar y luego activar por el password maestro del modem)
