WRT54GS v1.1 WAN port speeds?

    Just got an email from Virgin Media, informing me that they will be upping my cable connection from 4Mbps to 10Mbps.

    Now I think my WRT54GS v1.1 (running the 1.15 Tomato firmware) will run the WAN port at 10MB - but is the ceiling?

    Would I be better off buying another router, that is capable of obtaining say 50Mbps through the WAN port? There is talk of VM trialing 50MB connections, but obviously that's for rich customers - but I like knowing that I'm future proof. :tongue::wink:

    Anyway, if I were to buy a new router, it'd need to be able to run Tomato firmware. :cool:

    It depends at what additional services you are running. QoS and some filters WILL sap away at the cpu. Connecting, say a p2p application wirelessly will consume quite a bit of cpu as well. The general consensus is about 25-30Mbps max. the WHR-G125 may fare better because of its faster cpu. It may be the fastest tomato-compatible router. Also, you may wish to buy an "expensive" gigabit mimo 802.11n router, preferably dual band. Linksys models use Linux and their n/draft-n routers tend to use more advanced cpu's. I'm not certan of a good atheros-based router with a fast cpu. dd-wrt & openwrt has limited support for some of the new ones.

    If you need VERY high wan-lan speeds, I heard Cisco is pretty good :) or a decent PC runned as a router+a decent "managed" gigabit switch.

    edit: I forgot to mention that my bcm4712 (wrt54g v2 & wrt54gs v1.1), the max wan to lan wired transfers w/ several QoS filters enables is about 18 Mbps before cpu usage becomes a bottleneck, my Buffalo WHR-HP-G54 (bcm5352-based) is a bit higher due to its newer chip. WRT54GS v3.0 or higher & WRT54G v4.0 or higher & WRT54GL all uses the more efficient bcm5352 chips. Goto this link:


    to read more about it. Although it's not specific to the tomato firmware, it's relative speeds are similar.

    Anyhow, good luck!

    The WRT54GSv1.1 has a 100MB/s WAN port, also more flash/ram than most.

    Should be fine with 10MB/s

    I have 10Mbps/10Mbps, it works very well.. had 30Mbps to a few years ago, no problems at all.

    yeah similar here, I'm 17 Mbits down the WAN on my GSv1.1 with no probs with throughput.

    I can only get "close" to 25Mbps with a single wired computer placed in the DMZ in tests saturated with bittorrent traffic. Just by connecting a single wireless laptop, the wired computer's speed is nearly cut in half. Also the firewall is always on in Tomato, and having any sort of QoS enabled drops the speed quite a bit.

    May I ask how were you able to sustain 30Mbps without overwhelming the router's cpu? 10/10 is no problem, but 30Mbps is practically unworkable.
