Not on that router. Some routers allow you to load different firmware other than the manufacturers, likeThis is the router I have, yeah it's kind of old, like me, but somehow manages to still get the job done, like me...

I don't see any way to load any software onto it, factory firmware is up to date, is there a way to load other then factory firmware to it? Is that necessary? Or do I need to buy a new one? Hate to spend the money for something that still seems to work fine.
How does just shutting down and restarting the router fix anything?
DD-WRT, OpenWRT, and Tomato.
Here is a place to start digging into your router and looking for Firmware updates.
