    Since some time I have the WRT54G v7 at home.

    It functions fine for me, at least using a normal LAN cable.

    When I use WIFI, it does work, except for 1 big problem:

    I can't seem to get more than 1000KB/s when using Wifi.

    I have tried all channels, setting to G-only, toyed around with my LAN settings on the NIC, etc.

    It simply wont go above 1000KB/s.

    This is a problem for me, as my internet connection is 20MBit.
    So, now instead of being able to use my full 2000-2500KB/s, I am stuck with only 1000KB/s.

    Which is bad, cause I bought the router for the wireless functionality; but this way, I can only use half my bandwith.

    I just got a new beta-firmware today:

    Last Firmware Version: 7.00.3 (BETA FIRMWARE)

    Which supposedly fixes this:

    "- Resolves wireless data rate performance issues."

    Anyway, after installing this firmware, nothing changed.

    Does somebody have the same problem.

    Ie: when you use Wifi to download something from the internet, you cannot get above 1000KB/s?

    Got a new laptop, with different wifi nic, Intel 3945ABG, and exactly the same problem arises: still no speeds of 1000KB/s|10MBit when using my wireless to download things from the internet. So it is most definately a problem with the router.

    Nobody can tell me if they can reach speeds above 1000KB/s with the v7 router when using wifi to download something from the internet?

    Cause I'm curious if it is just a problem with mine, or a general problem with the router.

    Or, if u have another version of the router, do you reach speeds over 1000KB/s when using wifi to download something from the internet?

    1000kB/s = 8000kb/s = 8mbit/s

    are you sure your connection is a 10mbit one?

    My internet is 20MBit.

    My router & wifi nic are 54MBit, and the connection status gives Excellent as connection.

    When I use a LAN cable to connect to the router, I get speeds up to 2500KB/s (roughly 20MBit) when downloading something from the internet.
    So that works fine.

    But, when I use my wifi to download something, I never get more than around 1000KB/s. So thats only half the bandwith.

    And thats with 2 different laptops, and 2 different wifi nics. And I tried every possible setting on the router.

    So I guess it is the router's 'problem'. I'm just trying to see if other people can get more than 10MBit/1000KB/s when using the router & wifi.

    There is a possibility that this is your RWIN settings on your machine / NIC.

    Read this article: http://www.dslreports.com/faq/6266

    Win XP Default RWIN setting is: 17520

    Use this free program to adjust RWIN settings: http://www.dslreports.com/drtcp

    There is a sweet spot for RWIN (based on your internet connection speed). RWIN set too high, you begin to get drops. RWIN set too low, you are not maximing your download speeds. If you are using the 20mbit line all the time, set it to your sweet spot and leave it. Adjust accordingly when you use different lines. In general, find a setting that delivers smooth downloads and internet usage. Even at 50% download capacity for your wireless, you have a pretty fast line already.

    Let us know how this works out.
