"Cheap, but Unstable and Unreliable"2.5 starson by Tomilius
Pros: 54mbps, Good signal strength
Cons: MONTHS OF FRUSTRATION: Stops Receiving Important ARP Broadcasts, Can Be a Pain to Set Up, Windows Sometimes Stops Recognizing Device
Summary: When using this device along with the WL-500g (and probably other routers, because other devices don't have this problem with it), it stops receiving ARP broadcasts (at least--maybe all broadcast frames) after a while. That means computers on the network will be unable to contact it because it won't receive or reply to ARP broadcasts. Ouch. The only solution to this is to have it very regularly attempt to access a nonexistent IP address and then remove the invalid entry for that IP address from the computer's ARP tables and repeat. It can broadcast no problem, and that way other LAN machines will learn of its own MAC address and be able to contact it, but every once in a while it stops receiving ARP broadcasts. This does not commonly affect internet use, but it isolates the computer from the LAN in an EXTREMELY FRUSTRATING way.
Other than that, this device is pretty good with good signal strength and speed, except that sometimes (after it freezes your computer), it will stop being recognized by Windows until you do a lot of fiddling.
I gave this product a 5 for months of personal frustration and because important functionality is unreliable, and that is simply unacceptable.
