Using this wireless network card reduced my internet download speed from 2700 Kbps to 1200 Kbps. This is with a connection quality of 100 and only one other computer on the network with no applications running. Computer (in addition to the single browser window required for the test). Both computers were equipped with brand new DLink DWL-520 wireless network cards connected to a new DLink DI-514 router. As per industry standards, DLink appears to be servicing its first-tier phones with non-technical people who, while able to follow a scripted checklist, have no idea what's causing your problem or how their sequence of steps might solve it. So, after numerous calls, multiple case IDs, and never speaking to the same person twice, I figured it would be best to cut my losses and give up before they reconfigure my computer to stop working altogether. If you surf the internet a lot or play internet games, stay away from DLink products. Stick to a reputable name and save yourself the hassle and wasted hours trying to make cheap junk like this. The money saved is not worth the headache.
