I hope you can advise. I am a long time user of OpenWRT since WRT54G days, but have upgraded to several BT HH5A devices running 18.06 nicely for a few years. I recently bought another as a testbed - because few things ever go to plan - and flashed it with the latest stable image OpenWrt 21.02.1 r16325-88151b8303.
I went to configure the DSL WAN with the usual settings, but I have been met with: Error Network device is not present.
I have spent the last couple of days searching for a solution or material with which I can work out a solution that I could share. I have learnt a lot about the DSA changes in the latest releases and the change in syntax and structure (ifname to device), but there is a lot of early posts that refer to previous revisions - even the hardware device page is not current and I would append my findings there when I reach a remedy.
I have tried flashing different OpenWRT revisions to see how configuration and behaviour changes. Each flash was clean without configuration:
The lastest development release didn't present a browser interface, so I flashed a previous release using SSH.
The only revision that recognised the DSL was 18.06 which is years old, but made me think perhaps I have the name wrong, yet a post in the topic: HH5A - wan “device not present” after reboot this should work fine.
I can configure the WAN ethernet port using eth0.2 successfully as a test, but I want to use the internal DSL modem, yet it is not recognised.
Removing the test WAN my network config (set up for UK TalkTalk) MAC addresses replaced is:
config interface 'loopback' option device 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fd81:f7c2:61df::/48' config dsl 'dsl' option annex 'b' option tone 'a' option ds_snr_offset '0' config device option name 'br-lan' option type 'bridge' list ports 'eth0.1' config device option name 'eth0.1' option macaddr 'xxxxxxxxxxxxxxxx1' config interface 'lan' option device 'br-lan' option proto 'static' option ipaddr '192.168.1.1' option netmask '255.255.0.0' option ip6assign '60' config interface 'wan' option proto 'dhcp' option device 'dsl0.101' config interface 'wan6' option device '@wan' option proto 'dhcpv6' config switch option name 'switch0' option reset '1' option enable_vlan '1' config switch_vlan option device 'switch0' option vlan '1' option ports '0 1 2 4 6t' config switch_vlan option device 'switch0' option vlan '2' option ports '5 6t' config device option name 'dsl0.101' option macaddr 'xxxxxxxxxxxxxx2'
I am at a loss what to try next and feel I am now going around in circles and so Iwould appreciate some direction on a possible remedy.
