With the help of many of you, I've configured my BT Home Hub as dumb access point: BT Home Hub 5A as client over Ethernet
Now I have OpenWrt 19.07.4 r11208-ce6496d796 on it.
I need to configure openvpn on BT and I have to download packages, but opkg update fails with code error 7.
Can please anyone helps me to solve this?
Thanks in advance for the reply!
EDIT: I've solved, using my main ISP router as DNS. I don't know why it wasn't enabled. Maybe there was something wrong with the last update that deleted it.
