5 out of 5 eggsPower Comes in Small Packages

Pros: this device came with 3 main things, the device, the power cord, and the coolest part yet, AN ETHERNET CORD (rj45) figuring it out was quick and easy and the tech support folks were incredible.

Cons: i have yet to find one for this device

Other Thoughts: just a heads up, if you have a rent to own computer, with all the bloatware they put on them, it made it near impossible to configure the device. However once i got it set up i could unplug it and set it back up anywhere i needed to.

2 out of 5 eggsGood while it lasted

Pros: Cheap. Works well for what it needs to do. Easy to set up and install. Will not boost speed, but WILL boost coverage area.

Cons: My unit died. I started having problems a few months ago with the unit powering off. Only a VERY dim single LED (DIM orange). Would unplug it and it would boot right back up and work for a day or two and then crash again. Now I can't get the blue LED's to light at all. Have owned this and used it less than a year. It is a brick now.

Other Thoughts: When it worked it did what it needed to do, and I had full coverage across my entire house.

Manufacturer Response:

5 out of 5 eggsThe Best For The Price

Pros: Installed two and just bought 5 more. Very easy to set up. Works great, takes less than 3 minutes to set up. Set the wired connection on your pc to and then pull up Internet Explorer and put in to log into the repeater and it asks which wireless connection do you want to log onto.

Cons: It tilts if you 9dBi antennas. Just put a small counter weight on the top and done.

5 out of 5 eggsRepeating Myself

Pros: Easy/Simple guided set up.

Picks up and repeats a signal throughout a fairly large area/home.

Works without switching network IDs or names.

Speed for everything but large file transfers is the same as my router.

Cons: Sometimes in order to switch between routers, a disconnect/reconnect is required, which isn't mentioned in the manual.

Other Thoughts: It's a cheap but serviceable repeater that makes life easier, since my modem's on the west side of my house, but I spend a lot of time in the east side. I'm very pleased with this purchase, and would fully recommend it.

1 out of 5 eggsJunk

Pros: none

Cons: After following instructions it crashes and reboots and stops giving out dhcp and you can't get into management.

5 out of 5 eggsEasy to install !!

Pros: Installed this in a trailer on the water. Picked up the signal instantly and customer can use his laptop and his wife can use her i-pad anywhere in the house. Also worked with the wireless printer. The signal comes from the clubhouse which has a 6ft antenna on top of it.

Cons: Will tilt when using 9dBi antennas. Used a silver dollar to balance it.

Other Thoughts: Well worth the money. It can be set in set up in less than 5 minutes.

5 out of 5 eggsWorks.

Pros: Very easy to set up and works perfectly. I needed to extend my wireless network in my apartment so I could stream Netflix to the living room.

I had this extender up and running in less than 5 mins out of the box. Even comes with instructions for the less tech savvy.

Cons: None yet.

Other Thoughts: Could be cheaper for an off brand repeater, but I guess the higher cost justifies the fact that this repeater works well.

4 out of 5 eggsSolid performer at a good price

Pros: This is a stone simple device to set up, does exactly what it says it will do, and does it reliably. My home is about 50 feet from one side to the other. This device got me from a poor to an excellent wireless connection (specifically signal/noise ratio of 10% to 60% and from 5 Mbps to over 50 Mbps at the edge of my Wireless-n range).

As I move around the house, the network flips quickly from my base to the extension. I only notice the flip if I am using VoIP. Otherwise, it is seamless.

Cons: The device is a little flimsy - it won't take much abuse. The status LEDs are also very bright, and with the white plastic shell, they light up the entire device. But if you strategically place it where they won't distract you, you won't even notice it after a while.

Other Thoughts: As I type this, I am not sure that it would be an advantage to have the network have a unique name instead of just presenting my main name (like Wireless_Base vs Wireless_Extended) which would permit me to enumerate whether I want to specifically select my base or extended wireless ... but it is a point of curiosity.

5 out of 5 eggsBought three

Pros: Easy to install and set up.

Bought the first one 9 months ago and haven't had an issue with any of them.

Cons: Haven't had any

Other Thoughts: Worked out so well the first time I bought a second for another person, then a third for another after that.
