Absolute Garbage

Provides mediocre range, enough to make it to where I wanted. Biggest issue is that it CONSTANTLY loses connection and has to search for it again. Completely unusable. Do NOT buy.

  • from Ottawa, ON

Made a big difference

After upgrading to Bell Fibe 150 Mbps service I was disappointed at how slow wireless speeds were in my house, rarely exceeding 20 Mbps. I installed this unit last weekend and I'm getting closer to 100 Mbps on the main floor now, somewhat slower in the basement. Quite pleased with the improvement. The device was dead simple to set up as well. It took my network some time to find it, but once it did I've had no issues.

It kinda works... sometimes. I need to unplug and plug back in several times and i'm not that far from the main router. i say get a power line adapter and save the aggravation... i wish i could return this after 9 months of use.

loses connection

When it works, it's good - but at least once per day it drops the connection and won't reestablish. Unplugging it and plugging it back in seems to solve the problem, but it then takes considerable time to re-establish the link. Disappointing.

  • from Mississauga, ON

Super Satisfied

I was never able to get any wifi reception in our basement and in our backyard until I purchased this extender. We use Rogers internet and the main router is on the top floor so I plugged the extender into the wall in the living room of our main floor which is close to the backyard and right above my rooms in the basement. The wifi bars now remain full everywhere at all times. The set up was so easy as long as you follow the simple few steps in the booklet. I definitely recommend.

  • from Mississauga, ON

Worked as advertised

Easy to set up in 10 minutes. My router was in the family room at one end of the house. Added this extender to the middle of the upstairs foyer and now there is excellent wifi reception throughout the second floor. No complaints. Worth every penny!

  • from Calgary

Works amazing

Had the Linksys N600 and it barely transmitted. This one took less than 5 minutes to setup with an Apple ecosystem and it works flawlessly. Highly recommend.

  • from Barrie, ON

Very good

Easy to set up working great

  • from Salt Spring Island, BC

Didn't perform as expected

Bought it to extend the range to our small sleeping cottage 40 feet from our main cottage. It only allowed one or at the most 2 bars of capability, not enough for streaming, and cut out at times as well. Disappointed.

  • from Markham

Great extender, But

I love this extender. It is so easy to install and it works great with the many routers. Unfortunately it lack one or two features. I have a MAC filtering enabled on the wireless side of the router. Unfortunately this device allows any device to connect and bypass the filter, and what is worst, is that it won't allow to set a MAC filter on itself. This would be considered to me as a security risk, as it is very easy for a good hacker to get into any network with just a password. While MAC filter ensures no one get into your network as long as thet are not in the list. Another problem is that if tge Router has a hidden SSID, then it won't connect, but Syslink RE7000 can connect to a hidden network, and can set a MAC filter, but has speed issue. Another Extender to be returned.

Easy to set up, works great

set it up using their website, only took about two minutes and it works fantastic. It quadrupled the speed in my basement suite.

Get this one if you need an extender!

Linksys is always trustworthy! I had one RE2000 before and it works perfectly. Recently I need to replace the old one and I found a D-Link extender with "easy-WPS-Setup" function. So decided to try a different brand, but the WPS connection never succeed. I was really disappointed and directly return them and get two of these Linksys RE6400CA, set up successfully within 1 minutes with web based set up page and get wifi extended immediately. I strongly recommend this model since it supports both AC & N channel, range is really wide. Even in the far end of my yard it has really strong and fast wifi. It comes with multiple language when setting up, easy and fast. Perfect product!

Easy setup

Easy setup and fast ,Good production

  • from Lancaster, PA

Great product. Works exactly as it should

When I bought this unit I was worried that it would be hard to hook up, but it was Amazingly easy to do. All you have to do do is plug it in the wall near the router and wait for the light to turn amber and than click the WPS button on your router and then the WPS button on the wifi extender, wait for the wifi signal with the EXT at the end pop up and sign in. You then can look for the best place To find the best place for extending your Wifi signal, look for a spot that has around 2 wifi bars and plug it in around there and it will boost your wifi up to 7500 ft and Then you are done

Linksys wireless extender

I bought this product to extend the range of my existing Linksys router. The extender did what I wanted it to do. It was super easy to set up and the design is great for any location you want to put it in. I would highly recommend this product.

  • from Burlington, ON


Live in a high rise apt with lots of concrete walls. It solved the problem of getting wifi to other rooms.
