Since the default Netgear firmware doesn’t have DNS built in, I flashed the WNDR3700
with dd-wrt. But I was thoroughly disappointed with the performance even after following the settings from the wiki for the Atheros wireless settings.

netgear wireless n (5Ghz) 2ft ddwrt 78.2539s 6.9 MB/s 55.2Mbps
netgear wireless n (2.4Ghz) 2ft ddwrt 61.0922s 8.8 MB/s 70.4Mbps
netgear wireless n (5Ghz) 2ft ddwrt turbo mode 51.4871s 10.4MB/s 83.2Mbps
netgear wireless n (5Ghz) 2ft ddwrt turbo mode + tuning 52.51s 10.2MB/s 81.6Mbps
netgear wireless n (5Ghz) downstairs ddwrt turbo mode + tuning 272.237s 2.0MB/s 16.0Mbps
netgear wireless n (2.4Ghz) downstairs ddwrt turbo mode + tuning 226.537s 2.4MB/s 19.2Mbps

Clearly the tuning didn’t actually help, and the fastest I could get was 83.2Mbps but I got 123.2Mbps with the stock firmware. I reset the router back to factory defaults and was able to get 104.8Mbps which is still slower than it was before but it’s way better than dd-wrt.

This is definitely disappointing since I had such great success with Tomato firmware on my WRT54G.

  1. you might wanna check openwrt. the guy hacking for atheros/qualcomm on ath9k is maintaining lots of stuff there.

  2. Wireless being a ‘switchless’ technology is going to see inconsistent speed issues depending on multiple factors:
    1) Slowest system on network can affect speed for all other systems
    2) Conflicting frequencies can affect speed due to retransmits
    3) Various buffer-bloat items so that certain traffic gets high throughput for a short while but much slower throughput long ter,

  3. It looks like your testing of dd-wrt was only ever w/ 40mhz (turbo)… how was the stock firmware configured? Did it use 20/40, 20, or 40mhz?

    That can really make a difference depending upon how much interference you’re getting…
