BT hub 5A : WAN LAN settings - New Setup

KoKoKat · April 26, 2020, 5:30am

I have a new BTHUB5 based openwrt router. I can connect to TalkTalk, but neither LAN nor WIFI can connect to internet. What I want is to have the home network using the 192.168.0.xxx range with connected devices a mix of fixed IP and dynamically assigned IP's to guest devices. I'd also like to use google (8.8.8.8) as my primary DNS services, and TalkTalk's DNS as the secondary.

I've looked through similar "answers" on the forum but they don't seem to work. Nor did the Troubleshooting page (https://openwrt.org/docs/guide-quick-start/troubleshooting_internetconnectivity)

I am happy editing the etc/config/network settings. Or making changes via GUI.

Any help would be appreicated.

you should post your configuration files, cat /etc/config/network so we can see dsl configuration..

You mean the router has internet access? Can you, for example, ping 8.8.8.8 from within the router? How about any known domain?

Please post the output of the following commands. Remember to redact passwords, MAC adresses and any public IP addresses you may have:

cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Hi. Thank you for feedback. Yes, if I use diagnostic within openwrt then I can successfully ping/tracert to 8.8.8.8 and www.google.com.

You have too much of excess output at the end. You might want to delete that. And please use the "Preformatted text </>" button for logs, scripts, configs ad eneral console output.

I should have mentioned that earlier.

The default LAN IP of OpenWrt is 192.168.1.1.

If a user changes that IP in LuCI, there is a safety feature designed to ensure that the new IP is accessible by the device after the user applies the change. So if the new IP is on a different subnet other than the current subnet, after 30 seconds of trying, the user will be presented with an option to Apply Unchecked or Revert to the old IP.

If you don't take chances and you don't wish to Apply Unchecked, then immediately after you change the IP and apply, you renew your computer IP (for example disconnect and reconnect, whether it's wired or wireless) then you edit the router IP in the browser address bar to the new IP. That way the PC will find the router accessible on the new IP and therefore the IP change will not be reverted.

Alternatively, you can set two static IPs for your PC NIC adapter, say one as 192.168.1.10 and the other as 192.168.0.10 (for example), then when you change the IP of the router LAN interface, you edit the IP in the browser address bar from 192.168.1.1 to 192.168.0.1 and hit enter.
