I just got a DLink AirPlusXtremeG DWL-G650 wireless card for my laptop.
Will it work w/ .11g routers or AP's from other brands such as LinkSys or Netgear that also go up to 108Mbps?? I know it should work w/ the g or b mode but what about super G?

Is SuperG a standard that everyone uses for their "high speed" wireless routers?

Any feedback is appreciated.

SuperG is not a standard it is a Specific trick added to the chipset used by D-Link and Netgear.

The Super is achieved by bonding two channels and extra compression.

The SuperG card is compatible with other cards on 802.11b, and regular 802/11g.

For SuperG you need to use the same Brand SuperG counterpart.

Thanks for the quick reply.
So even though both DLink and Netgear use SuperG, my DLink card would only work w/ a DLink router??
(to achieve the theoratical 108Mbps)

Also, is LinkSys' SpeedBooster basically the same principle - combining 2 channels and compression??

I do not think that he Broadcom "Afterburner" Chipset used by Linksys is not using Channel Bonding.

In general the Chipset used by Linksys is slower than the Atheros Super-G used by D-Link, and Netgear.

D-Link/Netgear 45Mb/sec. vs.35Mb/sec, of the Linksys.

However the Super G slides out of Channel Bonding in the presence of 802.11b

The Broadcom "Afterburner" does better than the Atheros Super-G when the SuperG drops out of Bonding. However the Broadcom "Afterburner" seems to decline the Range fast.

So it looks like in Short range and presence of 802.11b you better off with Broadcom "Afterburner". All other situation Atheros Super-G.

If you use only 802.11g Super (no 802.11b) you are better off with the D-Link (it is less expensive than the other two it Kind of Cornered the Market of the Entry Level 802.11g Wireless).

Isn't superG 802.11n. They just jumped the gun and made their own standards.

Does that mean even the presence of any 11b device such as a wireless card will afffect SuperG, or it only matters when there's a 11b AP on the network??

Any live 802.11b, if a card is active and connecting it will depress the 802.11g.

At the end of last year there was a rumor that Broadcom is planning to ?Jump the Gun? and release pre draft 802.11n

Broadcom later deny it. The SuperG his on its own it is not early 802..11n

802.11n is suppose to work 2.4GHz and 5GHz and be compatible with 802.11b/g/a/n

The current release target is end of 2005.

I would not be surprise if ?Jumping the Gun? will appear in October 2004 ready for the Holyday Spree. Or early in 2005.

Does this mean a 11g router/AP can only serve in one mode, either G or B, but not both at the same time??

Or did you mean the performance will degrade??

That is correct. By default, an 802.11g WiFi AP will fall back to 802.11b transmission when it detects a legacy 802.11b client attempting to join the channel. Most APs will allow you to disable this compatability mode. However, doing so will result in legacy clients being unable to connect to that AP.

If you want to run both 802.11b and 802.11g without degrading the latter, you will need to purchase two APs, one of each standard, and run them on seperate channels.

Will it work w/ .11g routers or AP's from other brands such as LinkSys or Netgear that also go up to 108Mbps?

There are several channel bonding specifications out on the market right now. My Proxim 802.11a AP uses a 108Mbps bonding mode which only works with other Proxim/Orrinico WiFi devices. If I try to bring in another vendor's 802.11a WiFi card while I'm in 108Mbps "turbo" mode, it won't see my network. Even if that other vendor's WiFi card supports 108Mbps, it most likely only works with that own vendor's 108Mbps bonding mode. This also holds true for either 22Mbps 802.11b "turbo" and 108Mbps 802.11g "turbo" modes offered by other vendors.
