Before acquiring this adapter I had bought TWO routers attempting to connect to my modem (I had recently changed cable providers). The modem had to be placed in a room on the opposite side of my house (not more than 20 feet away). My computer refused to have a signal higher than a dot on the network meter. I tried numerous times to boost the signal from the PC to the modem and use the routers to bridge the gap, but neither one of them would ever connect to the modem. The meter would show all five bars lit up through the router, but I could never acquire a connection with them. I changed the channel on the modem which would work for about five minutes - the meter would show two or three bars, then drop back to the dot. On a hunch, I bought the adapter, installed it (very easy to do) and low and behold!! I had FOUR bars!! My computer is faster and I'm happier. Thanks to HP and Linksys for the adapter.
