Re: Router - Cable - Length

Lol - sorry, please don't be offended 😀. I had googled the max length for Cat 5 and found it was 100m, however , I am more concerned that a consumer grade router may not have the signal strength required to send a signal that far.

Thanks for your help!

Also - sorry, do I need a cross over cable or straight through?

Re: Router - Cable - Length

the limitation is more to do with propagation time of the signal rather than power limitations.

Doesn't matter these days, Ethernet devices are virtually all auto sensing now.
