I have a Buffalo G54 Air Station router that I bought through hot deals here in 2004 for $51 with a $30 rebate. Still going strong with about 14 atttached devices. Maybe gets rebooted once a month when I am troubleshooting something or power drops. Worried about finding something as good when it does die.
The most important question - Why on earth are you still using that? Network gear has come so far even in the last 5 years let alone the last 13. If you have anything remotely resembling modern broadband you are severely shorting yourself by holding onto that router. This is particularly true if you live in a congested area, in many parts of the US 2.4 GHz frequencies are nearly unusable with dozens of APs stacked on top of each other.
If you're happy with what you have it's probably because you don't know how much better life could be.

Settings are stored on the device. Not sure if there's a cloud backup of them, but a cloud outage doesn't affect local router use. It COULD affect initial setup I guess, as you have to use an app to set it up...
