PlusNet + OpenWRT + HG612 issues

Installing and Using OpenWrt Network and Wireless Configuration
#1

Hi!

Recently switched to PlusNet Unlimited Fibre Extra and decided to use an unlocked HG612 that had lying around. Its WAN configuration is as follows:

Layer2 interface: ptm1/(ptm1_0_1)
WAN connection: Enabled
Service list: INTERNET
Port binding: LAN1
Connection mode: Bridge
Bridge type: IP_Bridged
DHCP transparent transmission: Enabled
WAN 802.1q: Enabled
VLAN ID: 101
WAN 802.1p: Enabled
Value: 0
LAN 802.1q: Disabled
LAN 802.1p: Disabled

Its LAN1 is connected to the OpenWRT (a R6260 running snapshots) WAN port. OpenWRT WAN PPPoE settings are the default ones with the correct username and password. I do get a connection (even though occasionally it does take a while -- I have observed the same on the Hub One) and have Internet access, I get consistently disconnected after random periods of time with the unknown error (USER_REQUEST) or modem hangup messages. The only way I can get to temporarily solve this currently is by rebooting OpenWRT.

Anyone with a similar setup able to shed some light in this regard, please?

Cheers!

Does the HG612 work with any other router, such as the Hub One supplied by Plusnet (use the red WAN port) ?

Post the contents of the /etc/config/network from the R6260. Format the pasted text with </> button.

It does, yes. I'll let it run like this for a while and see if it shows the same symptoms.

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option packet_steering '1'
        option ula_prefix 'fd12:d255:962f::/48'

config interface 'lan'
        option type 'bridge'
        option ifname 'lan1 lan2 lan3 lan4'
        option proto 'static'
        option netmask '255.255.255.0'
        option ipaddr '192.168.111.254'

config interface 'wan'
        option ifname 'wan'
        option pppd_options 'debug'
        option proto 'pppoe'
        option password 'aaa'
        option ipv6 'auto'
        option username 'bbb@plusdsl.net'

config interface 'ccc'
        option proto 'static'
        option netmask '255.255.255.0'
        option ipaddr '192.168.112.254'

config interface 'ddd'
        option proto 'static'
        option ipaddr '192.168.113.254'
        option netmask '255.255.255.0'

Thanks for the help!

Wan interface settings look ok.

You are using experimental snapshot and I presume linux 5 kernel, whereas 19.07 stable releases for any other device uses 4.14.

Unlikely to resolve the problem as you did not report any ‘No response
to 5 echo-requests’ messages, but I would suggest you increase the timeout fwiw.

config interface 'wan'
            option keepalive '5 5'

Only other suggestion is to retest the VDSL modem with another router. It may have bad capacitors as Openreach stopped supplying the HG612 in 2014/15.

Sadly only snapshots are supported with R6260.
I'll let H612 running during the weekend connected to the Hub One.

Thanks for the help!

Just noticed that while on that USER_REQUEST error pppd complains of Timeout waiting for PADO packets.
