I have a Linksys router with can support b/g//n. I am thinking of upgrading my Airport Extreme to the new one which supports AC standard. For this reason I have ordered a Linksys Router which supports AC from Amazon.com. I am in a country which has 220-240 volts standards. This router is from the USA and it supports 120 volts. On the power adapter is written: INPUT: 120V - 60Hz 0.3A OUTPUT: 12V 1.0A The older adapter in my existing router has the following written on it: INPUT: 100-240V - 1.0A 50-60Hz OUTPUT: 12V = 2.0A Max 24W 12V = 2.0A Both routers have 12VDC/CC Power input Can I use the older adapter with the new router or do I need to buy a converter to convert from 240 to 120v?
