    I have a Asus WL 520gU, and it is unable to handle a full 100mbit connection (caps at about 30mbit, wired). The process is a Broadcom 240mhz, and I disabled QoS and Access Restriction for this test... and even then, it caps at about 30mbit, with processor load at 1.30 or so (which means there are 1.3 processes waiting to run, for every 1 process it can handle).

    Any ideas how I can somehow get a full 100mbit connection (from WAN to LAN). WAN side is a full 100mbit Cisco switch, tested to provide 100mbit when directly connected by my computer w/o the router.

    Others state the maximum throughput around 45Mbps, maybe you need to disable nat for that? Have you tried the teddy_bear USB mod, if compatible, which uses a newer kernel? Someone else has tried an OpenWRT 2.6 kernel on a Linksys device and it was much slower (but sure more 'features').

    The absolute max figure probably needs wireless encryption off, QOS and anything else processor intensive disabled. A little while ago tests showed Victek's 8515.2 seemed to be the fastest firmware around for the WRT54GL.

    Teddy Bear's version would be the equivalent for the USB machines. [But I don't know about the newer kernel, not seen any tests reported on the speed.] The ASUS machines have extra work to do if the USB and stuff is enabled, so, if you don't actually use the USB try Victek's firmware. Also, the chipset used in the ASUS machines is known to be slower, use Google to search for Oleg's comments on this in the ASUS forums.

    At the end of the day, you need a better router. (Asus RT-N16 would be my choice).
