This is a network card for laptops...I'm not seeing these long, deep ports on newer laptops, so this type of hardware must be phasing out.
Sometimes the device disconnects from my network, and I remove it to find that it is rather warm. This may simply be a combination of problems with my router and the fact that the laptop gets warm. In any case, if I give it time to cool down, then plug it back in, it gets right back to working. May be the fact that it's cooler, may be the fact that I gave the router some time to fix itself, but it works after that.
