I had always thought a 56K modem should get 56K transfers but they never did. It seems wireless N now gets 54K when setup with optimum equipment. It’s not noticable under most conditions, to be honest, but in case you were wondering about the wild claims from the industry, this is a real world result. Who exactly is supposed to be keeping these guys honest, anyway? At least the 802.11N broadcast signal makes it throughout our house, unlike the 802.11G. But you’re still better off wiring your house for speed.

Put it with my Vista 32 installation. Basically does not work. Loses connection to the router itself on a non-stop basis (every 3rd ping or so gives a general failure)

Works fine with XP from what I hear. Avoid this product at all costs if you’re on Vista!

Adding this to a computer is very straightforward if you have previous experience opening your box and adding a card. You need to first look at your computer board to make sure you can install a PCI Express receiver slot that fits this adapter. It took 5 minutes to install, and the setup using instructions included took an additional 5-10 minutes, moving very carefully and slowly. Instructions are well executed. Entire experience was painless and easy. Reception is good from D-Link DIR-655 Extreme N wireless router, but not at the speed I was hoping for. Traveling through a ceiling and one or two walls seems to prevent N speeds. Pretty much always at 54 Mbs speed, not anywhere near the possible 300 Mbs advertised. Using Comcast High Speed Internet cable connection, which has not been reliable in the last 1 month of installation. Goes out every couple of days or so. Needs to be unplugged from power, and reconnected and always comes back on. My previous 3 year old Belkin G router almost NEVER lost its connection, which has caused me concern. Only difference is that the G router was connected to a pc, and the N router was relocated and not connected to a pc. I don’t think that configuration should affect the connection. So, the DWA-556 adapter is working fine, when the router is working, except I cannot get the anticipated N speed of “up to 300 Mbs”.
