    Defecive Ethernet Cable, USB port lost power

    • My Best Buy® Elite MemberElite Member

    I've read a lot of the reviews and agree with many of the negative ones, while some are just not accurate. This Linksys EA6400 / AC 1600 was to replace a similar Netgear N600 WNDR3700 (Rev 1# that is now only working in 10/100 mode instead of the faster GB mode. Out of the box the included blue Ethernet cable did not work, had to use the one from my Netgear. Attached a desktop USB 3TB HD to the Linksys USB port and during a file copy to it, power was no longer going thru the router's USB port, Error 0x80070037; the specified network resource or device is no longer available. My HD is connected to a battery backup UPS and have never had a power issue with it. Plugged it back into my Netgear rounter and have not had any problems since. The Best Buy salesman stated this is one of the newest models from Linksys, this was a false statement, its at least 2 years old based on the document copyright stamp. As far as other reviews, I noticed a huge decrease in wireless coverage compared to my 4 yr old Netgear with all factors remaining the same. Yes you can configure the guest account with a password, it comes with one and was able to change it. The Linksys mobile app was free and worked fine. Some of the other avail apps were either no longer avail and the one #I forgot the name# that allowed you to control access to the USB connected HD, well there was a fee for that - I agree just not right as was the case with the parental control app, a feature that is listed on the box of this router. Overall, very disappointed in the quality of this Linksys AC1600. The one advantage Linksys provides over other manufacturers #not including Cisco that owns Linksys) is the 1 year warranty with 90 day free phone support instead of 30-day. There should be free lifetime support of the product like there used to be. I am returning this router to BestBuy and will shop for a new one early next year. MY TV, BD player, cell phones, iTouch all work okay with the Netgear, as does my HP laptop. Just wanted to take advantage of my HP's faster AC wireless module, something my Netgear does not support,

    Insufficient Parental Controls


    While the router setup and performance as a router was sufficient, the parental controls are not even close to what I would deem a bare minimum. I did try to get this particular part setup and running, but was underwhelmed from the beginning. The only things it had listed were the ability to block access at certain times, and you could input websites you didn't want to allow access to. Really?!!! Would this mean I would have to visit all of them to figure out what to include in this list? There was an indication that I could BUY ($2.99) an app for smartphone access/control. Again - Really!!! I thought such support would be included. Some quick searching online, and I was able to see screenshots for Netgear routers that offered far-more elaborate controls, e.g. a low-medium-high type of blocking action. All the other specs were comparable. Returned this router, bought a Netgear (R6300), and have already configured it to my satisfaction. The Linksys people may write back to indicate they have similar features, but if so, they weren't obvious in the software and to indicate that I had to buy an app to do this is unacceptable. Bottom line: if you are looking for parental controls, skip this router and go with the Netgear instead.

    Initial issues resolved

    • My Best Buy® MemberMember

    When I initially hooked up this router, my connection dropped off for a couple of minutes periodically on both the 2.4 and 5 GHz bands on multiple devices. I made one call to customer support instead of returning it and they had me hard set the channels for both bands. I did not think it would work, but I have not had trouble since. The speed has been good. I set up a plex media server and use it with multiple phones and tablets, a couple smart TV's and a smart DVD player. How well it works seems to depend on the quality of the device playing the media, not the router because on the newer devices, things work very well. I can even access the media server from outside my house. That is limited only by my DSL upload speed. I wish the app had more features. It is nice to monitor what devices are on my network from outside my house, but I would like easier access to the external USB device I have attached. The Plex media server fixes some of this issue, but there are some things I cannot do with Plex that I would like to be able to do and the seemingly simple external drive access setup didn't work for me. Inside my house I can use it no problem, but outside my house I have not been able to use it. I could have tried longer, but it wasn't trivial. I shopped around for a new router for a long time, and overall I am pleased with my choice.

    Use of USB 3.0 Device Causes Massive Speed Drop

    • My Best Buy® MemberMember

    I purchased this router on Black Friday. The overall specifications are fantastic and I especially liked the fact that it featured a USB 3.0 port. Unfortunately, after I added a USB 3.0 external hard drive to the USB port, speeds on the 2.4 GHz frequency plummeted to 10 Mbps. Additionally, wireless users in my household found that connectivity would drop-out for no apparent reason (even after the hard drive was removed from the router). The wireless range in my house was mediocre at best. After a little research, I found that there are potential problems with all wireless routers that have active USB 3.0 ports (try searching for 'usb 3.0 router noise issues' to find out why). It seems that some routers overcome the RF noise caused by USB 3.0 better than others. My experience is that the Linksys EA6400 does not deal with the problem very well. If you are considering this router to double as a NAS server, you might want to consider something else. I have since returned the router.

    Fast, Easy... and FAST.

    Routers are one of those product categories you don't think about unless it's not working correctly... And I went through a few before landing on this Linksys AC 1600 Wi-Fi router. Prior, I had been going through configuration issues, DNS issues, or problems where the wired connection would work, but the wireless would drop. With both my wife and me working for big companies from home, it was a big issue. It's important to note that while this won't increase the max data rate from the ISP *to* your home, accessing that data without a bottleneck, especially via your wireless access point, is essential. Also, your transfer speeds between the computers within your home network will be very fast, whether you're transferring large media files or not. Be sure to pair this with a gigabit-rated port extender if you need to add physical ports. The push-button Wi-Fi Protected Setup works great, and the AC standard, paired with my new iPhone 6, makes a huge difference in browsing speeds. You might be able to get away with a dual-band N600, but I recommend going AC- it's cooler. (see what I did there?)

    Horrible experience


    After my netgear wndr3300 started giving me issues a week and a half ago(around 6Dec14),i decided to try upgrading from wireless n to ac. After looking at the costs of ac routers decided to give this one a go since it was on sale. It worked great for a week days after getting it delivered but then it started power cycling repeatedly. OK, I thought, I'll factory reset it and see what I did wrong. And throughout that night and today, total of about 14 hours, I kept saying that because after setting it up, within half an hour after resetting it it would start cycling again. I went through the Setup wizard, then configured it myself, tried changing the mac address, different cables, ethernet cable only, wireless only, and nothing would help. I won't be getting another linksys, especially as they're owned by Belkin now.

    Not as good as expected.

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    My old router quit on me, so I was in the market for a new one. This seemed like a good combination of price and product. I followed the instructions exactly but I had trouble setting this up right away. Definately for me was not pnp. After 2 rounds with customer service both online and on the phone, I was given a solution that worked finally. Since then I have not had any trouble with my router letting me have access t the internet, at least on the computer. The other problem / issue is with the wifi. It is a lot less powerful I guess in its broadcast than I thought it would be. To be fair I live in a large apt complex, so there is a lot of competing signal in the air. So I could be getting interference from that, or maybe my tablet just isnt great with its wifi? Who knows, anyway so far the router is fine. Oh one other thing, just a fyi, it does heat up quite a bit so keep in a cool area.

    replaced 1st gen N Band router, glad i did

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite Plus MemberElite Plus Member

    My previous DLINK n-band router was contstantly dropping devices, forgetting ip address was a nightmare. I upgraded first to a dual-band but found every once in a while a similar issue. So i beefed up and upgraded to a full tri-band unit , this has been a blessing, reliable, easy to set up, and i can trouble shoot from my smart phone. I'm a above average user, basic understanding of networking, by no means an engineer. Running nearly 35 devices wirelessly including VOIP, dish media satellite, tablets, computers, printers, ps3, smart tvs, etc. This unit has handled the job perfectly with No complaints!

    The EA6400 is a fine router. What it may lack in performance against other 11ac routers in 11ac mode, it makes for in a sharp interface, easy setup and feature set. It's just that it's not a significantly different router from the EA6500 we sawFull Review
