WRT54GS performance degrades with non-GS cards?

    I currently have a desktop PC with a SpeedBooster card and a laptop with integral INTEL g wireless. They connect to the internet through a WRT54GS router. Does having a non-SpeedBooster connect somehow degrade performance for the PC with a SpeedBooster card? Thanks.

    There should be some. How bad is it on yours?

    There should be no performance reduction outside of the natural competition of two wireless devices, plus regular network traffic. Switching between Speedbooster (125+mbits) and "G" (54 mbits) can take a tiny amount of extra time/effort for the wireless router.

    Speedbooster also works with regular wireless "G" devices, but the improvement is only between 6 and 11 percent.

    Speedbooster, as implemented in the client card for 125+mbits, is a short range technology. If your speedbooster computer fails to recieve an IP address at long range, then disabling this feature on the client side is advised. The router will still continue to provide the 6 to 11 percent boost of regular "G"--but this time at much longer range. Long range authentication failure does not affect all Speedbooster (broadcom afterburner, Gplus, Turbo, Zonet/Belkin/Airport 125) clients, but it has been reported.

    You may use an updated firmware, such as the easy-to-use Thibor's HyperWRT and it will boost the speed and range of your wireless router. The forums of hyperwrt.org contain more information.
    The action of QOS in the new HyperWRT is rather harsh (to support VOIP) in comparison to Avenger's 21b1 origional work; however, both contain the benefit of bandwidth streaming.

    You can find QOS, Quality Of Service, listed in the Applications and Gaming section of the menus. List the MAC addresses for all attached clients. It does not matter much whether they are low or high priority as long as they are listed (low is okay). Put in a total speed of 83% of your advertised connection rate in the manual setting at the top of the QOS page. This step will activate bandwidth streaming (same as Hawking's Broadband Booster product) and allow fast simultaneous internet access for all listed clients (listed by MAC address).

    You may also choose to list applications by application port figure if they need more or less power. For instance Yahoo voice is yahooph, port 5055, high priority. Any Voice-Over-IP should be listed on high or highest priority. Bittorrent or peer-to-peer applications can be listed on lowest priority, yet they will speed up to max whenever there are no other demends on your Internet connection.

    I mention the QOS approach because it facilitates simultaneous Internet access that reduces the delays involved in having more than one client compete for Internet at the same time. The effect is astonishing. I have not fully tested the new codebase, but the origional work also gained higher network throughput while using QOS, even though QOS is not used for this purpose.
    Give it a try! ;)
