I have been experimenting with OpenWRT using a Raspberry Pi, however the PI cannot connect to the internet. After wasting many hours google-ing and trying every suggestion I can find I have reached the conclusion that something is critically wrong with OpenWRT. I have seen that a lot of people are having this problem, so I would like to start a discussion on how to resolve these internet connectivity issues once and for all.
Set-Up I am in my office, I just have a single ethernet port for my suite. So the office ethernet port is connected to a TP-Link (TL-GS1016S). My MacBook is connected to one port and the Pi running OpenWRT is connected using another port.
My MacBook pro is connected to the same switch as the Pi and the internet is working fine. I have Wi-fi disabled on my Mac. I can ping the Raspberry pi from my MacBook (ping 192.168.1.200) with no issues and vice-versa. Although I cannot access Luci via the IP address.
Process Download OpenWRT for Pi 4 from here: https://openwrt.org/toh/raspberry_pi_foundation/raspberry_pi Image: https://downloads.openwrt.org/releases/21.02.1/targets/bcm27xx/bcm2711/openwrt-21.02.1-bcm27xx-bcm2711-rpi-4-squashfs-factory.img.gz

Add IP Address using the following commands. Source: https://openwrt.org/docs/guide-quick-start/ssh_connect_to_the_internet_and_install_luci uci set network.lan.ipaddr="192.168.1.200" uci set network.lan.gateway="192.168.1.1" uci set network.lan.dns="192.168.1.1" uci commit /etc/init.d/network restart
However i still can not run ping google.com ping: bad address 'google.com' ping 126.96.36.199 PING 188.8.131.52 (184.108.40.206): 56 data bytes does nothing
Solutions I have tried. Add default gateway as there was no default when I ran $> route. Source: https://superuser.com/questions/854166/openwrt-software-update-wget-returns-network-is-unreachable
route add default gw 192.168.1.1 br-lan
route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.1
I tried adding 2 dns items to /etc/config/network
list dns '192.168.1.2' list dns '220.127.116.11'
