This is really cheap and easy to install but that is about if for the good points. I have had this PCI wireless adapter for 2 years now and I hate it, you ask "why haven't I replaced it...?" well I was so sick of trying different adapters that I just decided to buy a longer Ethernet cable, of which this suited me fine for the following 2 years. Recently I have moved house and having to relocate the router further away from my PC has reminded how awful the adapter is.
I have a laptop located in the same room connected to the same router and the connection is much more stable.
--It drops the connection probably 2-3 times an hour
--I have tried many different drivers, genuine windows and Linksys's own , all of which affect the device in different ways, some make the connection worse others make the device suffer at high bandwidth usage.
--The device is fine for occasional usage but after a few weeks you will see the connection drop now and again.
--Bad compatibility with Vista but not as bad with 7
--The antenna is about 15cm and sits out about 1cm so it gets tangled in all the cables behind your PC which can't be good for the signal.
--Installation is quick
--It's cheap I bought this for £16, I suppose I can't complain too much as some are £40+
Only buy if you want a temporary cheap fix. Try getting the later versions I had version 5, there are better versions now according to the reviews on the Linksys website. Check the forums to see which drivers people have found the most effective before getting really annoyed with it and sourcing out another device. I defiantly advise looking at alternatives. This may be more suited if you have a Linksys router. I have tried a netgear router and o2 wireless hub 2 and both have the same issue with this adapter.
Well, i have not purchased one for myself but for a neighbour who i installed it for. It worked fine, i had it install within a couple of minutes and the drivers installed very soon after that, picks up the wireless signal well.
The only bad point about this is that it has a rather large aerial on it, this isn't really a problem but can get in the way of other cables, but as long as it picks the signal up fine it doesn't really matter.
Overall it does the job and works fine.
