Netgear DGND4000 Optimizer

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)

Hardware specs:

• system type: 96362ADVN2xh
• cpu model: Broadcom4350 V7.0 (dual core)
• MemTotal: 124296 kB
• Kernel: Linux version 2.6.30 (root@BuildServer) (gcc version 4.4.2 (Buildroot 2010.02-git) ) #2 SMP PREEMPT Sat Feb 23 14:08:25 CST 2013

This little program will do the following:

• Enable telnet connections on 192.168.0.1
• Optimize kernel settings
• Set DNS to google's DNS service
• Disable unnecessary services to give more free memory and cpu cycles on router
