RT-N66U no internet after Tomato FW Flash

[Gordy]

My RT-N66U has not internet connection after I flash Tomato 1.28 by Shibby.
No connection via LAN or Wifi. After flashing the firmware I have cleard the NVRAM.
I followed these instructions as well as confirming with another youtube video which are the same.

I have tried these two firmwares and get the same result.
FW V: tomato-K26USB-1.28.RT-N5x-MIPSR2-128-AIO-64K.bin
I also tried flashing it with tomato-K26USB-1.28.RT-N5x-MIPSR2-131-VPN-64K.bin
When I flash the original ASUS firmware it works fine.

When I log into the router, everything looks good, shows the correct FW I flashed.
I did not make any changes after flashing, just tried LAN port and no internet, when I use my older WRT54GL router running Tomato, it works fine so I know the modem/ISP is fine.

Please help, thanks.

After flashing firmware of a new branch make sure to revert to factory defaults and configure manually.
Also notice the change in router WAN MAC address which may require reboot of your modem or even a timeout of your ISP to forget the old router MAC address.

Wouterv, thank you so much, rebooting the modem resolved the issue.
