Not sure if its much help but here is my ip a output (from Debian 11) which looks a bit like your working Manjaro install.

Code:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 00:1d:ba:ec:49:6f brd ff:ff:ff:ff:ff:ff
3: wlp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 00:24:2b:ef:db:27 brd ff:ff:ff:ff:ff:ff
    inet 192.168.178.184/24 brd 192.168.178.255 scope global dynamic noprefixroute wlp4s0
       valid_lft 863387sec preferred_lft 863387sec
    inet6 2001:7e8:c6bf:1d01:e1cc:51c9:6862:300d/64 scope global dynamic noprefixroute
       valid_lft 7156sec preferred_lft 3556sec
    inet6 fe80::7ab5:a8bd:5218:9817/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

Per this you may want to try
Code:
ip route add default via 192.168.0.1 dev eth0
which is NOT pesistent and if it works you can follow the answer to make it so.
How can I try connecting to wifi actually. I know that ethernet isnt working but not sure how to use wpa_supplicant on debian
alternatively I am trying to find a way of getting the iwd package onto a usb drive, if anyone knows where I can install it from?

Actually, what you get with the non-free debian isos is the firmware, which does not necessarily include the drivers for many of the wifi cards and usb dongles that can work with debian or linux. When the firmware is installed, the command: lspci, and, in the case of a usb: lsusb, should show the identity of the wifi driver that will run on that hardware and firmware. Then the user needs to determine whether the appropriate driver exists as a module on the system. That can be tested by booting up with all the firmware and hardware plugged in, so if it's a usb wifi dongle, it needs to be plugged in of course. However, it's often the case that no suitable driver as a module exists, or the kernel loads a module that doesn't work. The user then needs to find the appropriate driver online, download the source of that driver, usually from a github repo, and compile it before installing it and then having the kernel load it to get the wifi device to connect.

It's always worked for me.

I get what you are saying about the driver.
Been there many times.
