Can I Use A Gateway As Just A Router?

I have an aging Motorola 2247-N8 Gateway that I like to use with a broadband internet provider that is likely cable, not DSL.  Can I use this device as a router only?  If so, what do I need to do?

Pardon me if this question seems idiotic, but I am an old telco guy, so data is relatively new for me.

That only has 10/100 ethernet and most newer equipment has Gigabit ethernet.  I would recommend getting a newer wireless router that supports Gigabit ethernet and higher WiFi speeds.  They are typically less than $100.

Looking at the rear panel on an Amazon ad at , there is no Ethernet input to allow you to use this as a router without going through the DSL port (with a DSL connection).

The simple answer is "no".

Dave makes an excellent point.  You can get a new router and wireless access point for as low as $50 or so that would do the job well.  Spend more and you can get better WiFi (assuming your devices support the newer standards).

I had to replace my ISP modem today (old one was flakey).  The new ones have higher internal throughput (for higher speed) and integrated Wireless.  

This would be a good way to go given the increasing ISP speeds and residential users wanting all in one.

I figured this thing wouldn't learn new tricks.  I guess I'm in the market for a new router...
