Linksys WRT54GL v1.1 - dd-wrt sp2 NAT speed problem

    Hi,

    After so many posts I'm confused, totally confused what is WRT54GL/sp2 capable to do as traffic speed. Could someone help?

    I did very simple tests. I have LAN internet at home /40Mb/s - country peering and 4Mb/s International/.
    When I connect my laptop directly to internet cable I use wget to download one big file and got 2.6MB/s, I did it few times to collect average speed, so in worst case it was 1.6MB/s - 2.6MB/s.
    Then I connect internet cable to the router WAN interface and connect my laptop to the router LAN port. Downloading of the same file almost at the same time was up to 1.6MB/s.
    And finally I disconnect the laptop from LAN and use wireless /WPA2+AES/ downloading the same file was up to 1.3MB/s.

    What I'm really not glad to is the performance degradation of that router, I cannot understand why I lost around 500KB/s from direct internet connection and connection through LAN port on the router. The only think router does is NAT. I cannot believe that the router is so poor and simple NAT is causing such a degradation on LAN level.

    I asked colleague of mine to do the same test and he prove it, he found ~500kB/s slower download though router LAN compared to direct internet.

    Could someone help with this., is there any setting we can do and fix this stuff, I mean to reach almost the same speed on the LAN port as it it directly connected to the internet, especially when there is only one client and router does nothing else?

    Is that the router problem or it's combination with dd-wrt? Anyone tested any of other firmwares - openwrt, tomato ...

    Thank you in advance.

    DD-WRT SP2 is a bit slower than other firmware in my experience. You could try SP3 RC6, or Tomato or HyperWRT Thibor, which I found faster.
