Summary: I got this to use at home with an old Mac that I have that the kids could use to just go on-line. The Mac works fine but has no built in Wifi. The problem is the Mac is OS 10.4 and this device only works on OS 10.6 or later.
Pros: Moved into a new house and there is no network/cable connection in my home office. Bought this as a stop gap to get my desktop PC connected to my wireless router. Works well through several walls with a solid connection and decent speed.
Cons: I got a different product with a high gain antennae for my daughter's PC and it has a stronger signal. A few more walls and this one loses signal strength dramatically.
Summary: Product worked as promised. Transfer speed if great, quality unit for the price. I had trouble finding a USB wifi adapter for my Mac Pro after the AirPort Extreme went down. It was pretty much plug and play and solved my issue, very happy.
Summary: Sent it out for RMA (because of the 1 yr warranty), it took 4 weeks to get back. I am certainly not buying another EnGenius device because you can't rely on timely support.
Pros: Easy to setup requiring no installation of management software. Achieved full adversized speeds of 300Mbps. Did not use WPS Button. Worked well...until it didn't
Cons: The thing broke within a year. However, the device didn't just stop working, it started corrupting data. As a result the network didn't go out but became unreliable "every so often". It is probably the most annoying thing I have ever seen because tech support insisted it was software or configuration related. As a result technical support is telling me nothing is wrong and just uninstall reinstall drivers, uninstall other software, etc.
Summary: I have noticed that this usb wifi brand and model works well and is faster than the Rosewill brand units we have used in the past. Windows 7 loads the driver and I connect directly using Windows OS. I do not bother with the installation disk. I noticed my download speeds average 11 mbps and upload at 3 mbps through Comcast 30 Mbps service (we never get 30 and 24mbps is usually the most).
