[Bloat] Router ethernet devices do not connect to Internet after reboot

[Richard E. Brown]

Hi Ernesto,

> Hello everyone, I'm having trouble with my router that I had for quite some time when I first switched over to Cerowrt. Every time when I reboot the router which is a wndr3800

I’ve been playing with the CeroWrt firmware for a while, and haven’t seen this. I have a couple questions and some general guidance.

- You didn’t say which version of CeroWrt you were trying, but the 3.7.5-2 is very stable. It has a lot of the bufferbloat fixes, and worked fine as my primary router. You can get it from: http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/ 

- I always use the TFTP flashing process (http://www.bufferbloat.net/projects/cerowrt/wiki/CeroWrt_flashing_instructions) The one time I tried the sysupgrade, there was cruft left over from the previous build, and I wound up using TFTP anyway…

- It takes a long time for the firmware to get copied into the flash, and then start itself the first time. Wait 5-6 minutes.

- Make sure the router has finished the initial startup. You can do this by going to the web GUI at http://gw.home.lan (or 172 dot 30 dot 42 dot 1) and logging in (user/pw are root/Beatthebloat). If you get the Status web page, the router is up and running.

- I’m sure you’ve done this, but make sure you’re plugging into one of the four LAN “Ethernet" ports (not the yellow WAN “Internet" port). 

- If the LAN Ethernet is working, you should be assigned a DHCP IP address in the 172.30.42.x range.

I’d like to hear about what you find after doing this.
