Pros: Price, Works fine in XP or below

Cons: Will not negotiate gigabit in Windows Vista Or Windows 7.
No Current Drivers For Windows 7. And takes multiple trys to get Vista Driver to load correctly. Then Will only work at Gigabit until next reboot. Then no matter what you try will not go above 100mbs.
Talked to netgear several time, aware of issue but will not admit problem with card. No mention of new driver anytime soon

Other Thoughts: If you have or plan to upgrade to Vista or Windows 7 Avoid this card.

Pros: Reasonably priced for a 1000Mbps card... if it worked as such (please read below).

Cons: Did not work at 1000 BaseT while connected directly to a Gig-E switch. Took a long time to "negociate" a 100Mbps connection.
Updating the software / drivers is a very cumbersome process, that involves physically removing the card from the PC and re-installing it.
Neither the drivers delivered by Netgear on the CD, nor the updated ones from the Netgear webpage could make this card work at the full advertized speed.
For a 100 Base-T NIC it is too expensive.

Other Thoughts: I installed this card according to the manufacturer's instructions. Connected to the Gig-E switch, waited about a minute and the link came up at 100 bps. Tried two different cables, same result. Tried both the drivers and software that came on the CD and the updated version from the Netgear website. Still 100 bps.
By the way, updating the software is not a straight forward process either. The manufacturer's instructions state that the card needs to be un-installed in Windows and also removed physically, then re-installed in order to be able to load the new software / drivers.
Wasted a whole hour trying to make this work the way it should, to no avail.
Conclusion: The Netgear GA311 goes back where it came from.

Pros: Ease of installation and price.

Cons: When I inserted the disc into XP, setup didn't run, so I had to start it manually. After installing the hardware and turning on my PC, it found two drivers but it wasn't immediately clear which one to use. FYI: use the one that says OEM.

Other Thoughts: As I said, very easy to install. Thanks to the reviewers who said it doesn't work with x64, because that made me google to find out what version of XP I use, and why it doesn't work with x64. It doesn't work with x64 b/c the cost to make a driver for it would drive up the cost of their products.

Pros: Works with hackintosh right out of the box.

Cons: none

Other Thoughts: Newegg got it to me quick

Pros: Works on my 5 year old server, but wasn't bought for that computer.

Cons: Netgear does not have 64bit XP driver and basically tells you to go screw yourself if you don't want to use XP 32 or Vista!!!

This is becoming a trend where people like myself with new high-end systems that don't want to use Vista turn to XP 64bit and get stuck in the rain for driver support. Take the time and write a freaking driver.

Comes up in my OS as a Realtek product. Wish it was. Maybe they write drivers for their products.

Maybe newegg should have full specs on the hardware they sell including all OS's supported since we're in a time between XP and Vista as well as 32 and 64 bit.

Other Thoughts: Was going to be a bridged network adapter for a virtual server. Now I have to buy a different card. What a waste of $$.

Pros: Works in Vista 64

Cons: Drivers for WinXP do not work forcing you to use the older 2003 drivers which gives you 100m not 1000m. No help from Netgear support.

Pros: Upgraded our file server with this. Works great, and increaced the throughout of the server.

Cons: none

Pros: Only purpose I bought it for was to use it in a newly built OSx86 box. The documentation I found online said it would get recognized by OS X 10.5.6 right out of the box and it did.

Cons: None so far.

Other Thoughts: Would have liked it better if it was PCI-e instead.

Pros: Very good card. We use these where I work and I have so far installed 25+ with no issues. This one was for use in my personal network. Very good card and can't beat the price.

Cons: No issues at work or at home.

Pros: Breaks Windows less?

Cons: Used for months on both Gentoo and Ubuntu. Both systems would lock up randomly under heavy file transfer with any peers. I tried to track down the bug(s) in the realtek linux drivers but got tired of unraveling the kludge.

Jumbo frame steps only a couple times before hitting the max of 7200. The board has too many capacitors, this speaks to poor hardware design where the engineers built something then wrote the drivers to fill out what they had just built.

The Intel cards I purchased to replace these things have _NO_ capacitors and they include many jumbo steppings up to 9000.

Ended up repurposing them into some windows boxes that suffer a few reboots now and then. Tough to tell if the nics are to blame though.

Other Thoughts: The Intel Pro/1000 cards are cheaper now too. The two I have now work flawlessly.
