1 out of 5 eggsWorked, then not

Pros: Worked on Linux box, but...

Cons: Worked but then would stop working after a while. Had to reboot to get it working again. Pulling it out and putting back did not get it going.

Other Thoughts: If you don't need to keep it up for a long time it *might* be ok.

4 out of 5 eggsQuick Card

Pros: Quick way to upgrade a laptop to Gigabit.

Cons: I do have the appropriate card slot in my laptop for this model adapter (Toshiba Satellite A665-S6070). However, the card seems to need an additional 1mm of width to keep the connection solid. The slightest bump in the right direction will cause the connection to disconnect. I fixed this problem with some Gorilla Tape and seems to do the job well enough. -1star.

Other Thoughts: The card is extremely quick though, and installs automatically on Windows 8 x64.

I have it connected to my gigabit switch to a gigabit NAS. I can copy 4GB in under 2 minutes.

5 out of 5 eggsWorks fine

Pros: Works fine on my old Dell Inspiron 9400 running Windows 7 64 bit. Windows loaded the driver itself.

Cons: Not sure if it is a con, but there's a fairly bright blue LED you can see from the top and side, and it doesn't go out when I put the laptop into sleep mode. I don't know if the card is active and drawing significant power when the laptop is in sleep mode, but it really doesn't matter to me as I leave it plugged in.

You will probably want to get an adapter plate if you have one of the "Wide" Express card slots on your computer so the card won't wiggle around. Too bad they don't include one in the package.

Also, the card came in one of those damndable sealed plastic blister packs-- so be sure to have a good sharp pair of scissors ready to get it open when the card is delivered to you.

Other Thoughts: I had to reboot twice when first inserting the card-- once to let Windows finish installing the driver, and a second time when I moved the Ethernet cable over from the old port to the new one on the card-- For some reason Windows didn't want to network over the new card until I did that second reboot. Then everything worked fine.

As to the light staying on when the laptop is in sleep mode, I have no clue if that is an Express Card thing, a Windows thing, a driver thing, or a Dell BIOS thing.

5 out of 5 eggsPlug and Play

Pros: Worked right away in vista 64. Just plugged it in. and windows did the rest.

Now enjoy your faster transfer speeds.

Cons: Price, but there are not that many out there, so i'm not going to lose an egg for that.

Other Thoughts: Windows will find the driver. Just make sure you have your old one connected and your online. Windows update does wonders. Use it.

5 out of 5 eggsPerfect!

Pros: The card works automatically with Windows 7, no need to use the included drivers CD. But it's there if you have an older OS.

It works, speed is perfect on my gigabit lan. That's what I was looking for!

Cons: It's 34mm, and I happen to have one of those stupid laptops that take expresscards, but have the 54mm wide port. Don't know why Dell chose to do it this way, since there are VERY few 54mm expresscards out there, but they did. I saw a previous poster had a similar problem. I googled the words "expresscard stabilizer adapter" and came up with a company that sells 3-packs of these little plastic bits that hook on to 34mm cards to keep them from getting pulled around in dumb computers like mine.

5 out of 5 eggsWorks Fine

Pros: Added to my Dell 1720 that only had 100mb onboard

Cons: Sticks out from unit a little far (1.5"). Not too much of a problem since I leave the device on my desk when I am mobile

Other Thoughts: Dell 1720, Windows 7 32bit

4 out of 5 eggs

Pros: Installed just fine through Plug-n-Play on Vista x64 (was a little worried with some of the reviews).
It's the only available gigabit express card I could find.
Much better performance than the previous 100mbps ethernet.
Reasonably priced.

Cons: Up-to-date drivers not available from Belkin. Was able to find the Marvell drivers after reading one of the reviews.
Not expected gigabit performance (should be getting around 350mbps with my given drives, actually getting 250mbps).

Other Thoughts: As always Newegg rocks for delivery speed and prices. My laptop was the weak link in my gigabit network until I ordered this card.
The actual adapter is somewhat bulky, probably too much for typical laptop use, but mine just sits on my desk so it's fine for me.

5 out of 5 eggsWorks Under Freebsd

Pros: Main reason I got this card is because I needed to install FreeBSD Unix on a Dell laptop, but it would not recognize the built in NIC. I got this Belkin Card, and freebsd 7.2 recognized it without a problem.

Cons: None so far

Other Thoughts: This is a useful card if you are trying to install unix on some high end laptop hardware

3 out of 5 eggsGood, Bad and the Ugly...

Pros: Works fine with XP Pro after manually installing drivers. Works with Ubuntu Linux out-of-the-box. Throughput significantly improved over internal fast Ethernet card. I am using the 32 bit versions of each OS, so I have no idea if it works in a 64 bit environment.

Cons: I have a 54mm wide express card slot on my laptop. Although the product description says that the card should "install easy", the 34mm express card only fills-up a portion of the slot, leaving the card extremely prone to becoming easily disconnected. While the card technically fits, with nothing to hold it in place, just moving your laptop even slightly will cause disconnection. That wouldn't be such a big deal, if disconnecting the card did not result in causing the entire operating system to freeze up. The card protrudes so much that the odds of it getting bumped into are quite high in real-life, making it a real pain to have to watch out for. Just tugging on the Ethernet cable slightly will cause the card to disconnect, so this product is only really practical to use in a desktop environment where nothing EVER moves around. Simply not practical for portable or mobile situations. No driver installation or diagnostic software for Windows. Just base drivers.

Other Thoughts: The fault of the flimsy interface connection might be more of a problem with 34mm express card slots in general than this product. Why it is that laptops use a 54mm slot when 34mm cards are commonly sold is a mystery to me. I seriously doubt that the express card standard will survive, if my experience is typical. Was glad to see that there was no problem setting up the card in Ubuntu Linux. I'm guessing that any Linux OS with a fairly recent kernel will work fine with it. It's a bit disappointing that the hardware comes with no diagnostic software for any OS. I ended up "fixing" the flimsy connection problem by physically binding the card to the side of the laptop using a hot glue gun. It works, but it's a pretty ugly hack if you ask me.
