[Cerowrt-devel] Field Report - installing 3.8.13-7

[Rich Brown]

Folks,

I installed 3.8.13-7 on my WNDR3800. I used TFTP, not the default web GUI to upload the firmware. (Note - the recommendation is now to use the web GUI.)

I then ran two installation scripts to complete the custom configuration (see these pages for passwords, time zones, SSIDs, and also 6in4 configuration)

- http://www.bufferbloat.net/projects/cerowrt/wiki/Automated_Configuration_of_CeroWrt
- http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel

The router seems to be working as expected. I have not tried any serious performance tests, but a quick test of ping latency under load showed that the simplest-qos.h seemed to be working.

As noted above, 6in4 addresses seem to work, however, I did see a lot of error messages as a result of running the 6in4 tunnel configuration script. I've attached it to see if there's anything amiss… 

Thanks!

Done. You should restart the router now to make these take effect.
