Summary: Based on some of the reviews here, I bought this to replace a Linksys WPC54G card, which is not supported by Linux (Ubuntu 7.10) without some painful setup. It is revision B5. I had previously set up WPA on Ubuntu for my network. I booted Ubuntu on my laptop (an old Dell Inspiron 8100) with no card. After it was up, I inserted the G650. Ubuntu recognized it and connected to my Linksys WRT54G router with no problems.
Summary: I have an old Dell c600 laptop that is running Xubuntu 7.10. I stuck this in for my first attempt at Linux and wireless networking. I had it up and running in 10 mintues. Why 10 minutes? Because I forgot my network password and had to look it up. Seriously people, plugged it in, turned it on, entered password and surf the internet. I have been online for about 4 hours now with about a 60% signal strength. Got all my updates downloaded at about 250kbps.
Summary: Had this since early Oct 2006 and really like this adapter and because it is linked with a D-Link Extreme G wireless router at home, I get the high speed throughput that was missing with my old 802.11b card. Have used it on the road in at least 4 different locations and it picks up the wireless service at that location with no problems. Only problem I had was with initial setup (and that may be something in my settings as opposed to the card).
Summary: My brother has the Netgear WG511T Super G 108 PC Card for his notebook and it works great. So after I thought my Dell notebook internal wireless chip died, I decided to order a notebook adapter for it. Instead of getting another Netgear I decided to go with the D-Link DWL-G650 Cardbus Adapter 108Mbps - my first experience with a D-Link product.
Summary: I couldn't find this adapter locally, so I turned to Amazon.com. Naturally I found it. The price was right, I received the advertised rebate, and the product works as advertised. What more can you want? (P.S.: It's now 7 years later and it still works perfectly.
Summary: All, I Have used this card to connect to various routers and it works well. The Extreme G mode is problematic to enable sometimes. New drivers are available, make sure you down-load the right one. D-Link how about having an automatic update command ?, instead of letting the user figure out which card version he has ?.
Summary: The main reason I got this card is because it working in Linux (It has an atheros chipset), and it delivers. It works great, and the range is awesome. For Windows users, it works great in XP as well. Overall, I am very satisfied with this wireless card.
Summary: I decided to dust off a 5-year old laptop (Winbook Z1) the other day and install Ubuntu on it. I selected this card because of the Atheros chipset. I can't believe how easy it was to get it working. I plugged it in, installed Ubuntu and the new OS recognized the card. With in minutes I was on the internet, thanks to my neighbor's open WiFi. After a few hours of reading some wiki's and messages, I had WPA running and my "new" Linux laptop was on my network. Piece of cake!
