+ Seems a well-put together piece of hardware
+ Locked on to router and provided a decent-speed, solid connection that did not drop
- After installing it, my PC started to suffer from random, brief "stutters", most noticeably when playing back audio, but it would also affect other operations, e.g. the mouse would momentarily freeze up. After a bit of Googling, I cam across a piece of freeware called DPC Latency Checker, which gives a graphical representation of any DPC problems (no, I'd never heard of this before either - look it up). The software showed regular "spikes", indicating a problem, caused apparently by poorly-written driver software which hogs CPU time. The problem is, of course, working out which driver is causing the problem. The documentation that came with the freeware suggested disabling devices in device manager one at a time to isolate the problem, and also suggested starting with wireless network cards. Sure enough, I disabled the TP-Link card and the problem was immediately solved. I tried different versions of the driver from the TP-Link site, but no joy. So back it went to Amazon, and I replaced it with a Netgear USB dongle - I'd already got one of these, so I knew it would be problem free. Pain though, because I have more free PCI slots than I do USBs!
- The bundled software utility wouldn't install. Not a biggie, but it did say on the box that it was Windows 7 compatible.
Finally, be aware that if you are a Zone Alarm user, you will need to disable or temporarily remove it to get this card up and running, then you can reactivate / reinstall it.
