Information Systems Manager "Take" on Cable Modem Leas
Return the old modem. Wait on-hold while a tech configures his end of the connection and maybe even has to call you back later.
When there is an outage the finger pointing begins pointing at you. Now you have to prove the problem isn't at your end.
If they change the standards or protocols you might have to buy another modem, again! They could decide to charge you a 'service fee' on your own equipment later down the line anyway, say a $2.99mo support fee or some such but you've already spent the 'one year break-even' money and cant go back.
I SAY LET THEM MANAGE THE WHOLE BALL OF WAX AND STAY ON THEM FOR QUALITY OF SERVICE AND BANDWIDTH PERFORMANCE.
