Summary: I purchased this without reading the other reviews, and when I read them while waiting for this card to arrive, I got very worried. Fortunately, this card works great, and I didn't have the problems that others apparently ran into. Not breaking the antenna may have helped.
Pros: Inexpensive, great range, good signal quality
Summary: Ok...I was able to have a connection..so that a start...but who want a link unstable was going to 50 kb/s to 500 kb/s...even if it's was stable at 500 that way not enough. Test speed show 2 mb/s. On my Imac and macbook air and macbook pro(2006) i was getting 26 mb/s. After raging at it.
Summary: Easy install. The speed seems to fluctuate a lot! All the way from 1 Mbps to 144 Mbps. I scraped one of the antennaes against the wall and it came off, so I can't tell if the fluctuation is because of the (maybe) damaged antenna or just the product.
Pros: Fast at times
Cons: Not the best range, Antennaes need to be adjusted a lot
Summary: I purchased the PCE-n53 to replace a Cisco/Linksys AE2500 USB adapter. My experience has always been that internal cards provide much better performance and range due to the external antenna and fast PCI (or in this case PCI-E) bus. This is the first card I've seen where it's worse.
Summary: I needed a wireless alternative for my desktop computer and this did exactly what it said on the tin. All I would recommend is not use the software that comes with it, as it uses a lot of resources, so I'd recommend you use windows own wireless network services.
Summary: No connection issues at all, signal is full where my laptop used to have 3-4 bars. Connects to the network almost instantly (2-4 sec after login to Windows). Make sure it sits completely inside the PCIe slot, otherwise it will recognize the networks, but will fail to connect.
