Default Logs from wireless routers disclosing L2/MAC info?

Some of the popular wireless routers have an option to email
access/security logs to an account on the Internet. When enabled, the
logs contain the last 24 bits of the MAC address of the router's cable
modem port, (the rest could be guessed since the brand name is
included in the email,) and, the MAC address of the cable modem's
router port.

Isn't this risky.

Thanks,

John

Sending information is always.
The most important is you have the choice to disable it.

Yea, I really wanted the convenience, but I disabled it.

Thanks,

How exactly? What does knowing the MAC address get anybody?

If this is the MAC address of the WAN side of the router, then your
ISP knows it, and anybody else on that subnet knows it. Dunno what
they'd ever do with it, and nobody outside of the LAN can do anything
with it.

On the wireless side, it's sprayed across the countryside...

I don't get what your concern is.
