Connect the internet router to the switch with 2 cables - eviltoast

Hey,

this may be a stupid question but is it possible to connect my cable modem/router to a switch with 2 cables at once to get a higher max throughput? The modem only has 4x1Gbps port. I cant image that this is feasible but maybe there is a possibility. Otherwise my total throughput is limited to 1 Gbps although my internet has 1.2 Gbps.

And an additional question, can I connect the router/modem to any port of the switch?

Thanks

    It’s pretty rare for a standard cable modem to support bonding (LACP), however some aftermarket ones do. It’s worth poking around in the settings to be sure. Most managed switches do, so you’re probably fine there.

    With that said, with rare exception, you still cannot exceed 1gbit for a single flow even with multiple 1gbit uplink interfaces, meaning you won’t see any improvements on individual devices, but could see improvements in your overall network performance.

    E. I can get in to the specifics of why that limitation exists on bonded interfaces if you’re interested, but didn’t want to bog you down with unnecessary minutiae.
