Max-MTU DSL/LAN

I have a DSL line connected to my LAN. Should I change the Max-MTU setting from 1500? I have heard there is a way of determining the Max-MTU of my ISP?

check out the local info on this http://www.speedguide.net/Cable_modems/cable_registry_advanced.shtml

You will probably find that 1500 is too high.

My DSL starts to croak above 1472.

At the risk of sounding like an idiot this wasn't much help. I searched for maxmtu in the registry and couldn't find it. Any ideas?

i have been using all the info i could find from www.speedguide.net and it has helped me a lot but the one thing i can't figure out is that page "Determining your ISP's MTU"

it gives all these weird examples but i can't figure out how to get it to work
i would appreciate it if you could just tell me what you typed to see that the max mtu was 1472 or whatever you said

i mean an exaxt example

such as

ping 23.145.245.234

or something like that

thanks
