BEFSR41 V2.1 slows down internet connection

    I have a max. 20 Mbit/s internet connection. When I connect my computer directly to the modem I can reach about 16 Mbit/s. That´s OK. But when I connect my Linksys BEFSR41 router between my computer(s) and modem I can only reach about 5 or 6 Mbit/s.

    The modem (Davolink 2020) has also a built in router so I am cascading two routers. The modem/router combination uses the 10.x.x.x range as the internal network range. The WAN side of my Linksys router has IP 10.0.0.2. This address is placed in the Davolink´s DMZ, so there is no data blocking to the Linksys router. On the LAN site of the Linksys router I use the 192.168.x.x range
    Everything is working well except for the speed... Tracert, ping, nslookup gives me acceptable values.

    When I use the Linksys only as a switch to extend the number of ports the speed is also OK.

    The reason I want to use this setup is, that the Linksys can send forwardings to a broadcast address and the Davolink cannot. Wake on LAN from outside is only possible this way.

    Does somebody have an idea why the connection is slow when using the Linksys?

    Never come across a 2.1, but the really old BEFSR41 V1 or V2 only had a 10Mbps/half-duplex WAN port and couldn't handle more than 5 or 6Mbps...

    Thanks for your answer! I checked it out and indeed, the speed on the WAN site is 10 MBit/s :frown1: This information was "hidden" in the manual.

    Let´s find a new router which can broadcast the WOL package and which has a 100 MBit/s WAN. Do you know if the newer Linksys routers have this feature? Forwarding to a MAC address is also OK off course.

    The WRT54GL (L for Linux) would fit in the same place as a BEFSR41 even if you don't need the wireless right now. Don't know about forwarding WOL, but you can definitely ssh into a WRT54GL running Tomato (etc) and use the busybox ether-wake utility.

    Interesting, I have a BEFSR41 v1 and a 10 meg internet connection, routinely get 9.5 meg through it without a problem. Don't have the manual, but it appears that the WAN port on this version is 100 Meg, might have to try hooking something to it that can tell if it is 10 or 100 meg connection. Find it hard to believe it would be a 10 meg with the kind of throughput I get though.

    As far as the other question, if your cable modem is already a router, then just get a decent 10/100 switch and use that instead of another router, it is MUCH faster and more reliable than piggy-backing 2 routers. Just my 2 cents worth.
