Don't have it, and will now now avoid it. I assume the "Super" is marketing talk?
Nice speed and price, I currently have COX cable 4M/512K for $50. I'll probably end up switching to SBC soon and their DSL service as it's hit $15/mo. That's besides the point though...
I was more interested in what you currently use to connect the machine in question to your network. I'm assuming it's a 802.11b device. There can be a lot of things that prevent you from obtaining the performance your expecting, not all of the potential blame should fall on the wireless device.
1) 802.11b devices have several speeds at which the devices will associate: 1, 2, 5, 10 Mb/s Now you could be associated at 2Mb b/c
1a) The distance between you and the router is to large, or the signal quality too low
1b) The card thinks that it's found the best rate, when in fact it could do better, try manually setting it to 5 or 10 being aware that your tolerance to range and noise decreases when you do this.
1c) In simple terms.... 802.11b access points will take the lowest common denominator when it comes to associated clients. Thus if one client associates at 1Mb/s then all clients will use that rate. You may not have any other clients, but your neighbor may.
2) Your network stack is not configured to work well at such high speed. (like your MTU sizes, Advertised rwind)
This is mainly because venders have been slow to change these settings. You'll see it a lot when people hook up older computers to a network, even some newer ones.

There is also the possibility that you were testing your connection at a peek time where traffic on your ISP's local segment or the host for the testing site were congested.
Yes "Super G" is a marketing term for the non-standard extensions developed by Atheros and used in a few brands of 802.11g access points. It doesn't play nice with standard 802.11g devices.
