Hi,
could it be, that you switched from PPPoE to DHCP, but you still
connect by cable and not by wifi? There was likely an issue with the
modem and not with ADSL, so the modem to dial up was replaced by the
router. The router likely provides LAN and WLAN.

However, wifi unlikely is eth1, it should be wlan0, wlan1 ... wlann.
What's the output of
lsb_release -rc; ifconfig -a

?
I can't help you with Network Manager and also not really with wifi in
general, since I'm using a router by LAN, not by WLAN.
However, is your wifi thingy up?
If I connect a wifi thingy by USB, "ifconfig -a" shows it...
$ ifconfig -a
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
[snip]
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
[snip]
wlp0s19f3u1: flags=4098<BROADCAST,MULTICAST> mtu 1500
[snip]
...but it's not shown by ifconfig...
$ ifconfig
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
[snip]
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
[snip]
It requires to bring the Interface up...
$ sudo ip link set wlp0s19f3u1 up
...then its shown:
$ ifconfig
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
[snip]
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
