New Raspberry Pi 5 doesn't seem to work

[georgekatt]

Hi there, I've tried multiple ways to install RaspAP on a new RPi5 with Pi OS full, PiOS Lite, and Docker and after install, it doesn't appear to be starting an AP. In Docker on PiOS full, I got it to show an SSID quickly but it would immediately disappear. Any thoughts? I realize there's probably 100 things it could be, but this is a brand new Pi that connected fine to WiFi on it's own and I tried both the internal and an external WiFi dongle as well that listed compatibility and reviews showed as working with the Pi. Any thoughts would be appreciated!

This is true, and without supporting log output or other info it's impossible to advise you.

Instead, start with our top 10 common sense "do's and don'ts" checklist:

Replace every occurrence of eth0 and/or wlan0 with your interface names only if they differ in the following:

#!/bin/bash
iptables -I DOCKER-USER -i src_if -o dst_if -j ACCEPT
iptables -t nat -C POSTROUTING -o eth0 -j MASQUERADE || iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -C FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT || iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -C FORWARD -i wlan0 -o eth0 -j ACCEPT || iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT
iptables-save

Got it. Sorry if this is a stupid question,. It looks like I have a docker0, eth0, wlan0, and a wlan1 if I am in the OS (but that changes to wlxdxyz inside RaspAP docker container). Is it appropriate to replace eth0 with wlxdxyz? Thanks for taking the time with me here, I appreciate it!

These rules apply to the host's network interfaces, not Docker (as mentioned in the docs).

I'm sorry to keep having to come back. I've tried a lot of different things and just keep failing, so thought I would describe here a bit more detail.

Goal: I am trying to do a wireless repeater from wlxd123 > wlan0. It works on standalone OS. I then tried the Docker install.

"ip a" in either the host terminal or the docker pseudo terminal tells me I have (1) lo (2) end0 (3) wlan0 (4) wlxd123 (5) docker0.

I first tried replacing eth0 with end0 and wlan0 with wlxd123. I rebooted for good measure and that didn't do anything. I then replaced end0 with wlan1 because I did see that at some point and that didn't do anything, except that the host RPi OS keeps asking to authenticate my WiFi network and won't connect. I then replaced it back to the original firewall-rules.sh files and executed that and rebooted and it still won't authenticate my host WiFi, which has happened on and off before. I then tried replacing eth0 with docker0 and wlan0 with wlxd123 and that failed yet again.

Also to note, "sudo iptables -S" does not show the rules I created after restarting, but maybe I'm not looking correctly. Now, no matter what I try, my Wifi also never authenticates properly to any network.

Any thoughts about what I'm doing wrong?

If you don't need an isolated Docker container, I'd strongly suggest using a pre-built image instead.
