NETGEAR GA511 Gigabit Ethernet PC Card

This card works very well. I purchased the card for two reasons: 1) faster internet access than the wireless adapter I have and 2) to enable faster movement of files from the laptop to my home server using Gig-E. My laptop is running WinXP and the card installed without any problems. One of the easiest installs I have ever done.

I purchased this network card to install into an old Dell laptop with the intention of turning the laptop into an internet gateway/router. This network card worked great and was compatible with all linux/router distributions that I tried.

I bought this card for use with a linux laptop (Dell Inspiron 5100). And it worked right out of the box. I am running Fedora Core 6. Keep in mind that you wont be able to get the full gigabit speeds with a PCMCIA card. My cursory testing got me around 380Mbps.

First, make sure you get the newest drivers from the RealTek website (NOT the Netgear website--they won't work on XP). It is the RTL8169 driver and it is located under PCI devices on the website After installing the RealTek drivers and removing the Netgear drivers, the card started working fine and much better than the internal card on my old laptop. I haven't had the chance to run cable to my GbE switch, but I'll be happy as long as its faster than FE (although I don't expect much more than the 300 or so mbps limited by the Cardbus port). Definitely worth the 6 dollars for a refurbished one

It worked as advertised, and it raised my built-in antique laptop network wired speed from 100 to 1000! My laptop is an Intel P4 with Windows 7 Professional. When it works, it WORKS!

For anyone with a laptop without a built-in LAN adapter, this is a good solution. After downloading and installing new drivers from the Netgear website, this unit worked flawlessly and as expected right out of the box.

After meticulously following the installation instructions for Windows XP, I encountered nothing but trouble. First, the card switched to different speeds (10, 100, and 1000) so frequently that it was unusable. I tried different Cat 5e cables, different ports on my GigE switch (that another computer has no problems with), and even a 10/100 switch. Interestingly, the LEDs on the device indicated that it was able to detect & lock onto 1000 Mbps, right away. Disabling auto-negotiation didn't help, at all. I checked Netgear's site for an updated driver. The only one they had was labelled something like "Initial Version". As the name suggests, all the file sizes & dates were the same as the one on the included CD. Then, I tried upgrading the driver for my CardBus controller. This resulted in the computer becoming unresponsive, whenever a network cable was plugged into the card! Finally, in a fit of desperation, I checked Realtek's site for new drivers (the Realtek RTL8169/8110 seems to be the controller used in this card). Interestingly, the driver showed up in the "hot downloads" section - so it seems others may have been experiencing problems with this chipset, too. After I installed it, all my problems magically disappeared! SHAME ON NETGEAR!! I'll concede that the bar for product quality, across the industry, has been gradually lowered to a point where I'm not even surprised to find buggy drivers included with the hardware. However, I think it's virtually unforgivable that they failed to provide updated drivers on their website, when the included drivers were so poor and given that this product has been on the market for nearly a year!! This is my second experience with Realtek-based networking products that are virtually unusable - at least with the shipping driver. I will definitely avoid Realtek-based products, in the future. Even if I hadn't encountered the various driver problems, I'd still have difficulty giving this product a 5-star rating. My other complaints include: rather disappointing performance, excessive heat dissipation / power consumption, high CPU utilization, and only 3KB MTU jumbo frame support. I can't even hit 200 Mbps on a 1.4 GHz Pentium M, when the file is entirely in cache, and I'm transferring it to a very fast server. Upon ejecting, after use, the card is almost too hot to touch - I hope this amount of heat doesn't cause damage to my notebook & I would be concerned about using this card on battery power (though usually if you can plug into ethernet, you can also use AC power). When transferring large files (such as in my previous example), it seems my CPU usage nearly tops out - to be fair, I don't know if this is more the fault of the card, the drivers, or my notebook. Finally, if you're planning to use this on an exclusively GigE LAN, where all the other machines can be configured to use Jumbo frames, you'll probably be disappointed to find that this card only supports up to 3 KB MTU (even though the driver suggests otherwise, by providing an option including sizes up to 7 KB) - it should be noted that this probably won't affect at least 95% of users. On the other hand, the price is pretty good.

I am shocked that Netgear is providing an old driver (2004) NOT CERTIFIED WITH XP. Bought this Jan 2006. The crashing drove me crazy since nothing identified the driver as the problem until a day later through process of elimination. Wow. Netgear really blew it on this one.
