My mac keeps changing its name by itself!

I have a Mid-2012 15in Retina Macbook Pro, and ever since I installed the OS X beta Yosemite (my mac is now running the public released GM) it keeps renaming it self! Does anyone know how to stop this?
It's in your router, somehow it remembers your macbook name prior to Yosemite & now thinks it's another laptop with the same name (hence it adds the 2).
Should be able to fix if you reset your router.
I have 3 wireless routers in my home. Main Fios router, then a Cisco wireless routher connected off of the main via ethernet. Then a Linksys router after the Cisco. I can connect to the main or the linksys router & it won't change my name. But once I connect to the cisco router my name changes (like the op's).
This only happened after installing Yosemite. So I went into router to see where it was remembering my name & couldn't find it. So I removed the Cisco router & problem solved.
What you did stopped Mac OS X from changing it's name. The router is not able to force Mac OS X to change its hostname like that. That's something that only Mac OS X can do. Look at the previously linked thread and you'll quickly see that it isn't the router or other networking equipment, but a problem with the Bonjour wake service on Mac OS X.
It's something to do with sleep proxies. So far my MacBook Pro has gotten up to (8). Doesn't make any functional difference to me, it's just an annoyance.
It only seems to affect certain machines though. My 2012 retina does it, but neither my 2013 Air, nor my 2011 iMac do.
