DD-WRT Wireless Router Won't Respond

I have a Linksys WRT54G V8 wireless router that I installed "DD-WRT v24-sp2 (10/10/09) micro". This router is pretty limited in the memory department (only 8MB) which means even running the micro release can cause issues: slow network performance, unable to connect to the web interface, losing wireless connectivity and complete loss of network activity from the device. The only quick solution is to reboot the unit by pulling the power for 10 secs. So here are my tips on how to keep the WRT54G V8 running like a champ:

  • Set the max connections to 512 (You can find this under Administration>Management menu)
  • Set the TCP/UDP timeout settings to 120 (found in the same menu)
  • Schedule the router to reboot nightly (Administration>Keep Alive menu)
  • - Ensure that you setup the Time Settings found at the bottom of the Setup>Basic Setup page
  • Disable DNSMasq for DNS (Setup>Basic Setup menu)
  • Disable all services except for DNSMasq (Services>Services menu)
  • Disable UPnP (NAT/QoS>UPnP menu)
  • Disable QoS (NAT/QoS>QoS menu)

With these settings, you should have a rock solid wireless router that keeps running 24/7.

Issues to be aware of: This setup will limit the number of connections that your network can handle. That means apps like P2P and online gaming may run into some issues. I would not suggest using this router to support more than 10 systems at once.
