Summary: It is difficult for me to imagine that others have not seen this same failure since I (unfortunately) purchased three units over 3 weeks time and all three units eventually failed. (After buying and testing the first unit, I bought the other two for my girlfriend and my brother.
Pros: They worked for a few months.
Cons: I have bought THREE of these units. All three exhibit the same failure mechanism. After using the product for 3 months, all connecting devices show a Wi-Fi error. The extender then has to be turned off and then back on. This occurs more and more frequently (once every two weeks, once every week, once every day) until the unit refuses to reboot normally. (The front lights don't come on in the normal order.) I want to be very clear, this happened after 3 to 5 months on ...
Pros: My goal was to to extend the wifi in my house to the 2nd floor, so I was looking for an inexpensive compact n device that plugged directly into the wall. I didn't realize how compact it was until I took it out of the box. And for the cost (half price + $5 off coupon) it definitely fit the bill!
Cons: Would have given the device 5 stars had the setup been a little easier. The device has it's own initial dedicated IP address, which would normally not be a problem except that the device forces you to connect to your network on initialization. Once connected to your network (via DHCP), you loose the initial IP address and need to figure out what the new IP address is so that you can log into the device for further configuration.
Pros: The device is super easy to set up. I had mine setup and configured in a few minutes. It also doesn't take up very much space. It plugs into the wall like an air freshener, but rather than spraying perfume into the air, it sprays wireless internet. It does exactly what it is suppose to and it does it well, for the most part.
Cons: Once or twice a week, the extender has to be restarted. When I try to connect, it tries to assign the IP address for a few minutes before just disconnecting and I can not connect to the extender until I restart it.
Summary: Good little device. I am using it to extend a Netgear Pro-G 8 port router and the EW-7438w gives a stronger signal even though farther away! It is very easy to use; I'd recommend using the included cable initially, even though it can be configured wirelessly.
Summary: Setup was a bit confusing. Had problems with device not working right from the start, had one RMA. Second one worked ok for a while but then started having to be reset every few days due to not allowing any device to connect. Upgraded firmware to latest and had a lengthy chat back and forth with Edimax tech support via email, but still have to reset it every few days. Edimax tech support was helpful but then stopped communicating with me.
Cons: Refuses to hold a Wi-Fi signal. I do systems automation for a living and this extender refused to keep a Wi-Fi signal with my Cisco router. I have read other reviews where this extender has issues with Cisco routers, so maybe that is the root problem. It not only refused to hold a signal, it messed up another port on my router. I lost LAN connectivity on my router for almost an entire day. I had to go through an entire reset process before my system would work again. ...
If you want more control go with multiple DD-WRT routers

Summary: I was using 3 DD-WRT routers before, but decided to give this a shot when my primary router and modem got fried in a storm. Not worth it. Using multiple DD-WRT AP's allowed me to set them up as one SSID and roam between the access points with no problems.
Pros: It technically extends the wifi range. Pretty cheap.
Cons: Experience so far has been terrible. During setup you're supposed to be able to connect via Hostname, but this never resolves. Have to look at the DHCP tables and find the IP address and connect that way. Doesn't extend the current SSID so no roaming from AP to AP. Each AP has it's own SSID. I'm using 2 of these to extend my wifi with the internal DHCP server disabled. For some reason I get IP conflicts if I use the wired port on this device. Design is poor. Doesn't f...
