- Better wireless support
- Tweak power settings of the wireless router
- Quality of service, access control and network management
- Bandwidth monitoring.
- Increase range of the router
- Make your wireless router work as a repeater
and many more features.

Do this only if you need additional features and find the trade-off feasible or your router is off-warranty. One big trade-off could be the ability to increase the wireless router’s range compared to that offered by the default Linksys firmware.
