    Hi there. I have a Wi Fi LAN at home (802.11b). In theory this would be 11Mbps. My internet access is 3Mbps/1Mbps.

    Since I am going to move to a faster connection (10Mbps download), I am afraid the wireless network can become a bottleneck.

    With the current configuration, I checked the download speed before and after the router (I plugged one of my computers directly into the ADSL modem), and I noticed no difference. Conclusion, for the current speed, the WiFi router is not a bottleneck. Measured speed is something around 2.2Mbps.

    To fully exploit the future, faster internet connection, I am afraid I have to go for some WLAN hardware upgrade (router and PCI card(s)). Is it the case? And does anybody know if a 802.11g protocol (theoretical 54 Mbps) would suit my new 10 Mbps internet connection?

    And how can I measure the actual speed within my WLAN?

    Thanks in advance for any help....

    JohnWill has FiOS 15Mbps and has reported that 802.11g 54Mbps Wi-Fi gives good results for internet.

    About the best you can get from wireless is 1/2 the nominal speed, so you are correct that 802.11b would not give you full 10Mbps internet.

    I would definitely upgrade to g hardware at the least. With the theoretical 54Mbps of 802.11g, depending on your physical location and structure, you're probably going to see a noticeable increase in speed. I have two thinkpads at home, one old with 802.11b and one new with 802.11g and I sit them side by side in different locations and the g thinkpad is definitely faster to load web pages and on downloads/uploads.

    My two laptops using a wireless connection, one XP and one Vista, get around 6mbit-8mbit (depending on the phase of the moon) download speeds. If I connect them directly with a cable, I get the full 15mbit connection speed. This is with the machines very close to the router and lots of signal strength. My encryption is WPA, which can affect the speeds, unencrypted speeds would probably be faster.

    Thanks for your replies!

    To conclude:

    - if I go for a 10Mbps connection, I'd better choose a g connection; thought its actual data transfer rate will be in the order of 20-25 Mbps this should not hamper my Internet download capabilities
    - I did not notice main speed differences in the tests I made close to the WL router and in the attic (two floors above)

    Any more thought? Post them here.....

    Yep, the 802.11b connection will most certainly affect the transfer speeds from that 10mbit link. :)
