WRT54G WAN Performance?

    I just had Verizon FiOS installed at my home and have an old (v1) LinkSys WRT54G. Unfortunately, I don't seem to be getting the full 15Mbps downstream that I should. I've heard that the WAN port on the WRT54G is capped at 10Mbps until v5 of the WRT54G -- can anyone confirm this?

    I've also heard that the throughput on the WRT54G is limited (WAN to LAN/WiFi) to 19Mbps. I've even seen the review from Tom's Networking (http://www.tomsnetworking.com/Reviews-39-ProdID-WRT54G-7.php) which shows a transfer rate of 19.7Mbps -- but this review was done with an old version of the WRT54G in January of 2003.

    Basically, I assume I'm going to have to go out and buy a new LinkSys Wireless G Router, but I want to know which one will support 15Mbps (preferrably the full 100Mbps) on the WAN interface and which also has a decent transfer rate between the WAN and LAN/WiFi interfaces.

    Aftermarket firmware or at least the latest firmware will bring things up a bit for you, or should.

    I don't know about the cap at 10mbps, but there is a hardware limitation on the things that caps them at about 15mbps. It's a consumer router with a 200mhz (125mhz in your case) processor! That may be even lower on the V1 hardware as (if I recall) it uses a lower-speed processor.

    Supposedly (and I have not tried this myself) a WRT45GL (the last of the Linux models) with any of the HyperWRT builds or even native firmware should get you at least 15-16mbps.

    I'm stuck on 3mb down / 256k up, so I can't really give you any good numbers based on personal experience. However, before you replace it, you may want to just give HyperWRT Tofu a try:


    Another option would be to dig out an old computer if you have one and load up M0n0wall, Smoothwall, or IPCop, and use that to do your routing.
