    I am having slow transfers on the wired Ethernet LAN interface and I get about ~1.7 MB/s instead of ~10 MB/s that I get when I connect another computer directly to the cable without the WRT54G.

    WAP: Linksys WRT54G v6 802.11bg & 4-Port Fast Ethernet (100Mbps) Router (2MB RAM Nefred Edition) (Firmware: Linksys 1.02.05 and DD-WRT V24-SP1)
    Router: Linksys BEFSR81 v3 8-Port Fast Ethernet (100Mbps) Router (Firmware: Linksys 2.51.3)

    I'm a systems admin and here is what I tried. Linksys firmware upgrades on both routers and also DD-WRT install on the WAP router. Two different laptops with RealTek and 3Com NICs and both laptops tried with Auto or 10-half/full, 100-half/full duplex settings. Changed MTU settings on the WAP router from 1500 to 1400. Other things that I'm forgetting. Both laptops give 10 MB/s transfers when using the cable directly.

    Below is a thread that I found with someone else having the exact same problem as me.

    This information coincides with my findings and I have to say that all the Linksys WRT54G v6 router with only 2MB of RAM and VxWorks OS are broken and cannot deliver any faster speeds. At this point I'll be posting router up for sale since there is nothing else for me to try short of hardcore nvram tweaks or hardware resoddering. I'll be buying a competitor's product now.

    Stop yourself from replying if you are going to recommend a solution involving anti-virus disabling, spyware clean up, os reinstall, faulty router, cabling issue, or something else you think might work but aren't really that sure will.

    Dude, get real, nobody buys the WRT54G V6es. If you were smart, you would've bought the Linux version(s) or, better yet, a WRT54GL v1.1.

    Who cares? People buy these routers not because they're brand junkies but because these particular routers are dirt-cheap and run 3'rd party firmware, and with that kind of firmware installed they become best bang for buck. So no need to shove some brand bashing down our throats, as this is not a Linksys-owned forum nor a community of Linksys hooligans. You could've just told us, in a polite fashion, to stay away from the WRT54G V6es. And then we would have thanked you.
