Note: The factory clock setting for the NETGEAR R7000 is 1000,800 (1000 MHz CPU, 800 MHz RAM).ģ. Paste the following commands into the Command Shell:.Navigate to Administration > Commands.Here are the steps to achieve the highest stable (YMMV) overclock: Likewise, if you have Internet service faster than 50 Mbps, you might want to experiment with the max speed to can get over VPN, then downgrade your Internet service to match it, saving money on your ISP bill in the process. The numbers also suggest that, if you have Internet service slower than 37 Mbps, there would be no benefit from overclocking, so don't bother. It would seem VPN throughput is CPU-bound, as the router crunches the crypto math for the VPN, so every bit of CPU speed helps. The highest measured VPN throughput achieved in the 1400 MHz test was 44.17 Mbps that's not much less than the non-VPN speed of 50 Mbps! As these numbers show, it's possible to achieve the maximum stable overclock of 1400 MHz with little impact to CPU temps, even under the load of an Internet speed test. All VPN speed tests were performed using a 50 Mbps Internet speed tier, running 3 times on a wired client, and averaging the results. Analysisīelow are some of my own real-world VPN performance results with CPU temperatures under load, comparing stock speed to overclocked. Further discussion of overclocking settings can be found in the DD-WRT forums.ġ200 MHz or 1400 MHz are good bets. In general, avoid overclocking the RAM on this router. The DD-WRT wiki page for the NETGEAR R7000 states this router "supports CPU overclocking (1200MHz and 1400MHz possible)". Kong has stated in the DD-WRT forums that this router has a good amount of thermal headroom: ".the R7000 definitely does not need any extra cooling as these chips can easily do 90 degrees." Other posts about ARM CPUs generally agree under 80-90 C core temp is considered safe. Kong's changelog shows some test results where a 20% CPU overclock increased WAN-LAN throughput by about 20% in very high throughput scenarios. That being said, overclocking is known to increase NAT Routing Performance and OpenVPN performance. Don't sue if you break your stuff! The following instructions and statements pertain specifically to the NETGEAR R7000 router (Broadcom BCM4709A0 CPU), which is the recommended router for this guide. Overclocking has real benefits, but could overheat your router and damage it. Private Internet Access VPN paid subscription, with a strong password.Router with DD-WRT revision greater than 24710 installed (recommend the NETGEAR R7000).If you followed my Instructable on how to Install and Configure a DD-WRT Kong Router on the NETGEAR R7000 router, you are all set for this VPN guide. This guide, however, is written for newer builds, specifically Kong revisions >24710. Some older routers are actually more stable on old K26 builds, or even require it, so I have written a guide specifically for those older DD-WRT versions. OpenVPN setup on DD-WRT differs between older and newer revisions. For recommendations for other VPN providers, see the end of the guide. Bonus! This guide assumes you are a paid subscriber to Private Internet Access, with a PIA username and password.įull disclosure: I am a (satisfied) customer of PIA, but I have in no way been paid, contacted, encouraged, etc. Finally, they are one of the least expensive VPN services. Third, they have no restrictions on running a Tor relay inside their VPN. Second, the company has gone on record about their opposition to government mass surveillance. Why Private Internet Access (PIA)? First, you can tell them to donate a portion of your subscription to a worthy non-profit that works for Internet freedom,. There are tons of great consumer VPN companies to choose from. This guide shows a DD-WRT user how to configure the OpenVPN Client on a DD-WRT router to use the Private Internet Access VPN provider to encrypt and anonymize all Internet traffic on their LAN. Running a VPN client on your router offers the benefit of seamlessly routing traffic from all devices connected to your LAN through the VPN. In an age of Big Data and mass surveillance, a consumer VPN is a great way to stay more secure and private on the Internet.
