The Netgear DGND4000 (WiFi DSL Modem Router - Premium) is an excellent router as such. Unfortunately it has a few issues that Netgear has no intention of fixing:
- It forces all DNS requests to go through the routers own forwarding service. Caching of requests is disabled ($$ business feature $$), so only effect is that every DNS request takes longer to complete.
- Number of concurrent connections (nf_conntrack_max) is set relatively low (compared to the routers hardware capacity)

This little program will optimize kernel settings, set DNS to google's DNS service, and disable unnecessary services to give more free memory and cpu cycles on router
