    Hi,

    I have a MBP 1.1 with OSX 10.6.8 and when connected to my 802.11g network my bandwidth seems to be capped at 10mbps , we have 40mbps internet from brighthouse and other computers on the network get the full 38-39mpbs on the same wireless channel. When i switch to the 802.11a 5ghz network from the same router i can get around 17-20mbps while sitting 10 feet from the router. When i plug the computer into the router i get the full 38-39mbps. This is starting to blow my mind, it seems the airport extreme card is limiting the connection. any input would be greatly appreciated, google hasnt gotten me anywhere so far.....

    OPTION/ALT click on the AirPort/Wi-Fi icon in the Menu bar and tell us what it says behind PHY Mode, Channel and Transmit Rate.

    -on 802.11g , channel 11 the nearest neighbors router is on channel 9, transmit rate 54 and rssi -50, 18.09mbps down / 3.01 mbps up

    -on 802.11a channel 44, rssi -67, transfer rate 48, 20.3mbps down / 3.66mbps up

    I have used cocktail to lock the duplex to full which i have heard is a problem, on osx 10.2 but not 10.6.8m. Cocktail boosted me from a straight 10mbps no matter what connection to the current problem.

    I just tried disabling the 5ghz on the router to see if that was the causing the bandwidth to be what i think is exactly half of our full speed. No change . blahh again we have 40/5 internet and hardwired 39.55 / 4.56

    It looks about right.

    You'll never get the full rate over WiFi, it's typically about half the transmit rate. Which is what you are getting.
