2 out of 5 eggsAvoid Linksys

Pros: Once setup, it works. Mostly. See cons...

Cons: Has to be the worst device I have ever had from Linksys. Ever since my WRT54G, I've never been happy with a device from Linksys. However, in a pinch for home internet I picked this device up as my Netgear gave up the ghost. I acquired this device in March, and here we are in October and it's mostly dead. But not all dead. Now, every device in my house works if it meets one of the following conditions:

1. Wired directly to the router.
2. Is not a laptop.

Tablets, phones, game systems, and everything else except the laptops worked great on the wireless. The laptops would connect and after a minute would go to Limited Access and we could not get to anything on the network. Connected same laptops via wire and it worked flawlessly. Connected same laptops wirelessly to a portable hotspot and they worked flawlessly.

So, after much struggle, a full reset on the router, and attempting to disable everything not needed on the device, they still don't work. It's like the wireless radio just didn't want to work with the laptops anymore.

This is the third device I've had from Linksys (including the WRT54G) and this one and the last one were pure junk. I shouldn't be 6-7 months into a router and the wireless radios start being selective about what devices they will service. If the router were 2+ years old I would understand, but this is stupid. I dropped this router off my network immediately put in a router from another maker (ASUS) that setup faster and easier and with less fuss.

Other Thoughts: Linksys, get your act together. You used to be the king of home networking, now you're just the jester. Get the bloated garbage off the router (Smart WiFi? My backside...) and just make a device we can use to access the internet and allow us to turn on features as we need them.

Manufacturer Response:

Hi Joseph,

Your feedback is of great value to us and we hope that we can still change your perspective towards our product. Here are the possible solutions that you may do:

• Make sure that you have a stable connection to your modem.
• Position the router away from windows, thick walls, and move it to the floor where you're most likely to use Wi-Fi.
• Adjust the router’s wireless channel to avoid possible interference in your network. Use the Wi-Fi analyzer app. It helps you to find a less crowded channel for your wireless router.
• Update or re-flash the firmware.

If the connection will not improve, you can send us an email at LinksysCares@linksys.com with your contact details, location, and the link to this review so that we can assist you further.


Regards,

Linksys Support

5 out of 5 eggsGreat Router

Pros: You DO NOT need to make an account to use this router.
Very simple to set up and the wireless speeds have over doubled compared to my old router. (it too was Linksys) The menu is well thought out and easy to use. Download the App and you can monitor your router anywhere. Really like that you can see what devices are connected to your router.

Cons: None that I have found.

4 out of 5 eggsI like it

Pros: Easy to use, configure & setup.
Speeds are good on 2.5Ghz
I like how I can divide the download speed so I can stream a movie and download a large file without one interrupting the other.

Cons: None

Other Thoughts: My WDLive TV media player doesnt support 5Ghz.

My Cisco DocSis2.0 cable modem drops my internet connection about once every 2-4 weeks. I can see how someone can think its their router dropping the connection but the majority of the time its your cable modem or your ISP.

I did not have to create a linksys account as one reviewer had said. You simply login to the router like any other 192.168.1.1

I think this router offers a lot for the money. I'm not using all of it's features and could have purchased a router with less features and have been equally as happy. But I purchased this with longevity in mind, I hope not to replace it again for another 5-8yrs. I call it future proofing. :)

4 out of 5 eggsArrived

Pros: Easy setup, so far it works as advertized

Cons: none so far

Other Thoughts: Product came looking new but not in the original box. Had to factory reset because original password it should have been would not work. Otherwise all works as it should.

4 out of 5 eggsIt works

Pros: The firmware configuration is extremely well done I didn't have to change anything other than network names and passwords...no tweaking required.

Cons: The biggest con is that it doesn't have an external antenna and therefore it's not going to have the best input and output over greater distances.

Other Thoughts: RE: the review of Edgar L. who wrote "I am an IT technician. I make 100% of my income from my IT consulting business. I have been doing this for over 15 years. I am not some idiot user"

Edgar the genius "IT technician" is 100% wrong in this comment: "one of the options to sign into the router requires you to SETUP AN ACCOUNT WITH LINKSYS???!?!?! ARE YOU FREAKING KIDDING ME?"

You ABSOLUTELY DO NOT have to create a linksys account to login the router. I DID NOT, although it seems like maybe you do, if you don't think a little bit.

1 out of 5 eggsWORST ROUTER EVER

Pros: ABSOLUTELY NONE

Cons: FIRMWARE, everything else.

Other Thoughts: I am an IT technician. I make 100% of my income from my IT consulting business. I have been doing this for over 15 years. I am not some idiot user who throws up their hands at the first hint of a problem. I have setup and installed countless routers. Everything from Cisco (real Cisco, BTW) to the cheapest and worst D-Links. I have I have never run into anything as horrible as this router.

The firmware is absolutely horrible. Not surprisingly, I am not the only person who feels this way. Do a quick Google search to find out how much users like "Smart Wifi".

Linksys has done everything in their power to prevent you from simply accessing the router configuration page. One of the options to sign into the router requires you to SETUP AN ACCOUNT WITH LINKSYS???!?!?! ARE YOU FREAKING KIDDING ME? I just want to configure MY router. Well, just use the default password like their website says in the FAQ... Good luck with that... doesn't work.

I used to think that HP printers had the worst firmware developers in the industry. I was wrong. Somehow, through great effort and horrible decision making, Linksys has surpassed HP. Linksys needs to round up every developer who touched this firmware, every mid-level manager who supervised its development, and every executive who green lit "SmartWifi" and fire them. Not just fire them, blacklist them. Publish their names so that no one in their right mind would even think about hiring them.

I cannot stress this enough. This is the worst product I have ever had the misfortune of using. PLEASE choose something else.

3 out of 5 eggsNot as good as I hoped, but kept it

Pros: It works fine for 90% of the people who buy this. Didn't notice any speed issues.

Cons: It's not DD-WRT compatible, nor is it ever likely to be. Why is this an issue for me? I have 2 FTP servers that I like to access over the internet. No matter what I did, the firmware would not allow more than one FTP server to be accessible. I tried using different port forwarded ports, different IPs, and I even changed my NASs from a static IP outside of the DHCP pool to being inside the DHCP pool with a DHCP reservation. I simply could not access both FTP servers. Yes, I swapped their settings as well and I was able to access the other, so it's not a NAS issue. As I was able to do this quite painlessly on my old Netgear WNDR3700 with DD-WRT (which a storm killed), I suspected that it wasn't the hardware, but the firmware.

But with *VERY FEW* firmware updates available from Linksys (probably due to them being bought by Belkin from Cisco and they're favoring their own builds), while making the issue known to tech support with no answers to date, and their website forums being stumpped, I then made a similar mistake on purpose and bought an EA6500.

Why? Well, I knew there was definite DD-WRT builds for that one, but I wanted my question answered as to whether it was a firmware limitation or not. I set the EA6500 up the SAME WAY.... and got the same problem. After flashing it with a good DD-WRT firmware, I set it up similarly to my WNDR3700 and.... it worked! Both of my NASs are now available via FTP again.

Other Thoughts: I am keeping my EA6400 though as I believe I can still use it as a decent wireless bridge. Eventually I'll have time to set that up.

1 out of 5 eggsPoor performer, Terrible customer service.

Pros: Gigabit wired
AC wireless
USB3 port
lots of features

Cons: Unstable performance
Needed new firmware immediately
Requires periodic reboot
Linksys customer service is a joke

Other Thoughts: This router would NOT share out either of the drives I attempted with it, and one is specifically listed on Linksys's website. After troubleshooting via phone, Linksys agreed to RMA and then had no inventory to send as the replacement. So, now I'm stuck with a router that doesn't do what I needed. And they charged my credit card for the return before it even shipped. I'm not normally a big reviewer of products. This is not the first bad Linksys experience I've had, but it WILL be my last! Buy something else if you don't want to end up in my situation.

5 out of 5 eggsI really like this router

Pros: - Great range
- Slim, attractive design
- No drops or reset issues
- Slick UI
- App upgradable
- Guest WiFi zones
- Full AC speeds
- Configurable dashboard
- Easy parental controls
- NFC setup

Cons: - NAT loopback does not function
- UI sometimes lags at first load
- NFC card is easy to lose
- No availability of DDWRT or OpenWRT as yet
- Settings menu names are a little odd

Other Thoughts: I really liked this router. It felt like a slick upgrade and natural progression for linksys' offerings as of late. With four people using it on a number of devices I haven't had any noticeable slowdown or dropping of wifi devices, and it seems to perform fine on both 5ghz and standard 2.4ghz frequencies.

For those wondering about 5ghz, it enables higher speeds and in situations where there are lots of wifi networks (like dorm rooms of apartment buildings) then it helps alleviate congestion-related connection issues. In my 1k sqft apartment I had consistent coverage for the entire area with the router located in a far corner. For a larger house I would image it would need to be in a more central location if you want to use 5ghz.

It had an included guest network which sequesters visitors from your LAN, hiding your files and devices. It works well for random visitors, but you will probably want to give your friends full access.

The router has an NFC configuration card, and with some smartphones you can tap it to configure wifi access. I kind of wish it was both on the router and the card, since the card will be the first thing to get lost for sure.

The chassis is fairly durable, and it mounted smoothly on the wall. Some competitors have been taking the soda-bottle shape router approach which are a nightmare to wall mount, so this was a welcome relief.

The router includes an auto firmware updater, and when I first connected the router it notified me there was an update available. The firmware update process was the fastest I've ever seen, and was finished in just a few seconds.

Port forwarding and all other standard configuration options were easy to use and did not cause a loss of internet when applying the settings.

I was severely disappointed by the lack of function NAT loopback, which enables network resources to be accessed using the external IP/hostname. Hopefully this issue is resolved in future updates, as its absence in a router of this price is baffling.

I feel like this router would work well in homes and businesses, but the NAT loopback issue might give you pause. If that kind of thing doesn't bother you then this unit works great, I really like using this router.
