@Hegabo@vgaetera First, I need to thank you guys. Yesterday I can't saw and can't found out the 'Reply' button. I can saw @vgaetera edited him answer twice times. But I can't send any personal message to you I'm so hopeless . I used the openwrt two night and found it's not as stable as official fireware. So tonight I flash back to the official fireware. Thank you guys again. Have a nice day!
The problem here is revealed that your upstream "WAN" network (likely the LAN side of a modem / router) is 192.168.1.1, which conflicts with the LAN in OpenWrt. That makes it impossible to route anything to the Internet. The other firmware is likely using 192.168.0.1 as the LAN, which will work.
