WRT54G WAN Throughput

    I am new to this forum and also to the alchemy firmware.
    I have optus cable which allows up to 10Mbit/s downloads. However with my WRT54g connected (alchemy final release firmware), I can only get about ~5Mbit/s throughput max from the WAN (i.e. roughly 500-600 Kilobytes/sec) whereas with my DLink 704UP router, I can get about 900-1000 Kilobytes/sec (~9Mbit/sec).
    I would like to continue using the WRT54G, but does anyone know why it seems to be limited to 5Mbit/sec. I do not have QoS turned on, and most settings are left as default.

    I am just wondering if this could be a limitation of the alchemy firmware?

    It very well could be. I know there were some throughput problems with Satori, but I haven't looked into them much.

    I also have 10Mbit down (ool) - I see full speed when QoS is turned off, about 75% of full speed with QoS on... I am running a WGR54G V3 with Alchemy final V1.0 (since yesterda - just got it....)

    Careful "young grasshopper", dd-wrt is a fork of Alchemy therefore inheriting this issue I would almost guarantee. There have been many users reporting speed issues. Speed issues are related to a number of factors including ISP services. When talking firmware, the performance can be attributed to added kernel modules and Boardcom drivers. James (sveasoft) even indicated one of the limiting factors is the RFLOW patch added to the kernel. idv(sveasoft forum member) created satori-4 turbo which was consider for a while one of the best performing firmware versions. This fork used version wl.o driver from Broadcom.

    I was unable to find it anywhere so I placed it here for anyone who is interested.


    Please note it was compiled only for older WRT54G models. Do I even need to say use at own risk? Don't blame me if it bricks your router.

    Maybe a speed test could be performed in a new thread. Perhaps using something like http://www.mikrotik.com/download/BandwidthTest.zip to compare the different firmwares.

    thanks this looks cool

    Two days and still full speed (10mbit/s download, 1mbit/s upload). I don't think it's the firmware... Maybe you have a duplex mismatch between your CableModem/DSL and the router? Power off both, power up the CableModem/DSL - wait until it's up, then power on the router and try again... Otherwise you could try a different CAT5 cable - maybe the cable is borderline and the dlink negotiates fine while the Linksys is having problems....

    For the love of God, can you, jagboy or someone else please re-host the file? I really need to try out this firmware. I can also host the firmware for the long-term. PM if you'd like tell me directly where to get it.

    Sorry for the mix up, geocities messes with the direct links. I have placed it on a new project folder on savefile.com. Sorry for the extra steps but this should work this time

    I would try running the Talisman Firmware instead of alchemy. Especially the latest version it is pretty stable.
