Stupidity of the CGM4141COX panoramic wifi modem

So I just upgraded to this CGM4141 modem because the previous modem I was using was a bit outdated.

Now the first thing I noticed with this device is the fact that you cannot use special characters when setting the router access password which means that you cannot have a strong secure password and will leave the login page rather vulnerable. The next thing I noticed is that there is no option to change the network name for my ethernet so I stuck with my Ethernet connection being name SETUP-22df i have scoured every option in the setup page of the modem with no success. 

If someone has successfully changed this option could you point out how you did this....
