Summary: The update driver function in Win7 Device Manager said it could not find newer drivers, but the mediatek site shows a much newer update was released for the Ralink RT2860 chipset. I downloaded that installer package and it ran without issues.
Pros: The card installed automatically in Win7-64 Home Premium on a Compaq V6120US.upon insertion into the slot, with what seemed to be generic Win7 drivers that were dated in 2009. Those are the drivers I'd recommend.
Cons: I don't recommend updating the driver with the package found on the mediatek driver download site for the Ralink "PCI/ mPCI / CB(RT2860/ RT2760/ RT2890)" dated 11/29/2012!
Summary: This particular notebook usually has a wired mouse and keyboard attached to 2 of the 3 USB ports, so leaving the third one open for a flash drive rather than using it for a WiFi adapter was pretty much necessary.
Pros: Works fine, installed without issues in Compaq Presario V6120US; immediately connected at 135 mbps with good signal strength. Plug and play, no need to use driver CD with Win7-64.
Cons: Not the most stable in the ExpressCard slot but for $5 with promo code I am not complaining. Not worth a one-star deduction.
Summary: The internal wireless card on my old laptop died. I ordered this on Monday, it arrived Thursday. Put in the disk, click continue a few times, it tells you to install the card, and that's it. No muss, no fuss.
Summary: I wouldn't worry with trying this if you have anything outside of XP or Vista. Truth is I don't know if it's a dead adapter, or if it's the fact I've got Windows 8, but I'm not going to bother sending it back.
Pros: It was cheap, worth a try.
Cons: I had Windows 8 and was tinkering. It didn't work, nor did any of the lights work at any point. I tried several versions of the driver, the Medialink drivers, with and without the utility, which never opened. It didn't even show up in the Device Manager, so the computer wasn't even "seeing" it.
Summary: Found this, ...The key to making this product work is to neither use the included installation CD nor install drivers provided by Belkin. Instead, use the reference drivers from this card's chipset maker, Ralink. Go to Ralink's web site and navigate to the support section.
Pros: Doing preresearch
Cons: Nothing yet, but found something that might be helpful to those with Windows 7 and Windows 8, which I have.
