TWO ISP's, anyway to bond them together?

    I have comcast high-speed internet (8Mbps download and about 760Kbps upload)

    I also have Bellsouth high-speed DSL (3.5Mbps download and 368Kbps upload)

    I have one WRT54GS V.4 with DD-WRT v24 SPI-final firmware
    I have one BEFSR41 V.4
    And the comcast cable modem has a wireless interface and ethernet interface

    How should I setup my network so that everyone can share the same connection or atleast alternate between them if one fails to operate, as a wireless network (all of my 7 computers are either laptops or connect through a wireless adapter).

    google on "dual WAN router load balancing".

    The RV0 series
    However..realize the difference between "load balancing", and "bonding" won't get bonding. So in your won't get 11.5 megs. However..on another note...a larger enough network that can saturate both WAN ports with load balancing..the router will ultimately put through up to 11.5 megs due to spreading the load across both pipes.

    Get an old box, slap Linux on it, 3 NICs - 1 in from internal network, 2 out to modems, and set up load balancing. That's the "old" way. I guess the new/elegant way is to do the same on a router :)

    A sort of load balancing might also be achieved by setting both gateway IP addresses on your clients - the 2 interfaces to the modems. One of the gateways will have priority (the one specified as the first gateway on the clients), but, if you run dynamic routing, you might just get lucky. I doubt that you will ever achieve the combined up or down bandwidth though.

    Another possibility might be a type of mesh network setup, which I understand is basically the clever dynamic manipulation of routing tables. How that can be set up is way beyond me...

    Yes An old pc with m0nowall or smoothwall would do, however the RV042 or RV082 would be an easier option.

    I picked up a 2nd RV042 for £45 inc shipping over the weekend off ebay! I had to have it at that price!

    Well, I'm now going bankrupt and I got no cash to buy anything so im just going to design my own network with the only equipment I have left.

    Like I'll just connect both the DSL and CABLE modem to a LAN switch and use the uplink to connect to my WRT54GS v.4. Then, whenever an ISP fails I'LL just switch to another ISP by changing the router's info. on the setup tab. Also, I can plug in the BEFSR41 v.4 router to the switch, bridge the DSL modem, and have the BEFSR41 to connect to the internet(to have an ethernet network), while the WRT54GS connects through the cable modem(to have a wireless network). Then, if the cable or dsl modem fails to operate I can just connect a pc to the switch and configure either the BEFSR41 or the WRT54GS to take over. Like if the cable connection fails to operate I can disable the BEFSR41 and have the WRT54GS connect through the DSL modem.

    I don't need any further replies, I found an alternative to the situation.

    Thanks for the "load balancing" idea.

    if you have an old pc (specs are minimal) and use monowall as it is free. you just need a few nic cards and your elected.
