Speed limitation at 4 Mbit using ActionTec and Linksys??

    Hi folks,

    Scenario:
    * I have upgraded my Internet connection from 4 Mbit to 8 Mbit
    * Using my wireless connection I can still only get 4 Mbit
    * Using direct cabling adslmodem/PC DOES give me 8 Mbit

    Which makes me believe that either my Linksys router or my ActionTec Wireless adapter is somehow limiting my speeds....

    Hardware:
    - ActionTec 802.11b, USB, wireless adapter
    - Linksys BEFW11S4 version 3

    Any suggestions?


    Thank you in advance for your kind help,

    What happens when you connect your PC to a wired port on the router? If that works fine then it's definitely the wireless connection, which wouldn't suprise me since you should never expect to get more than 4-6Mbps at most out of your 802.11b equipment under optimal conditions. (Excelent signal strength, no interference & only a single wireless client using the network.)

    For example see here (the green line is an 802.11b NIC communicating with an 802.11g router - taken from this review) and here which shows the BEFW11S4 getting a top speed of 461KB/sec which translates to about 3.7Mbps

    it would most likely be both of them.

    Standard 11b devices generally deliver 11 Mbps link rates and actually peak at about 6 Mbps throughput; standard g and a products have link rates of 54 Mbps and will generally deliver throughputs of 18-22 Mbps

    hope this helps.

    you could try setting

    Beacon Interval: 50
    RTS Threshold: 2304
    Fragmentation Threshold: 2304
    Basic Rates: 1-2-5.5-11 Mbps
    TX Rates: 1-2-5.5-11 Mbps

    however there is limitations on Wireless 11b that will not give you full speed. you would need to really upgrade to 11g devices.

    where did you find optimal settings (beacon, rts...) for g wlan ?

    Its time for 11g I guess..

    It is quite clear to me now that I need to upgrade to 11g, router AND wireless adapter.

    Thank you both for your answers and your help :)
