After a reboot it started to work


This is also the case on the Atheros routers.
After adding a new DHCP server you have to restart the router otherwise the clients of the VAP can't get an IP address somehow.

I assume that something is not started via the "apply" button.


Just tested it again with build r47822.
My statement seems to be no longer currently true.
Either fixed or that was related to a specific configuration (I would have to search the thread in which I had found that).

Anyway, it doesn't fit into the broadcom forum

Does firewall startup support bourne shell script? It seems that whenever I put the following in firewall startup, it doesn't execute on reboot.

Code:

sleep 5; /jffs/scripts/restart_wifi.sh

OR

sleep 5; sh /jffs/scripts/restart_wifi.sh


The script only runs when I manually run the command or click edit and save the firewall command via the web ui.

Permission seems ok.

Code:
root@ac88u:~# ls -l /jffs/scripts/restart_wifi.sh
-rwxr-xr-x    1 root     root           198 Dec 21 22:43 /jffs/scripts/restart_wifi.sh
root@ac88u:~# grep restart_wifi /var/log/messages
root@ac88u:~# nvram show | grep restart_wifi
size: 56533 bytes (74539 left)
rc_firewall=sleep 5; sh /jffs/scripts/restart_wifi.sh

First of all you do not need the VAP workaround any more (in recent builds, currently 47900).

Second yes the scripts will run (if executable etc.) but only if available.

It can take longer (10-30 seconds) before /jffs is online.
So either increase the sleep time or use the built in is-mounted utility to wait until the directory is online
(is-mounted.sh /jffs)

But I would just upgrade Smile

Thanks. The reason I need the script to run is because I can only get static dhcp assignment to work after restarting both wifi and dnsmasq.

I think the issue is that the dhcp-hostsfile doesn't get mounted before dnsmasq starts up.

dhcp-hostsfile=/jffs/etc/config/static_leases

I am not sure if there's another way of doing it?

Have you tried to restart DNSMasq after /jffs is up?
Code:
is-mounted.sh /jffs (or sleep 20)
restart dnsmasq


I have my static leases in Additional Dnsmasq Options like:
Code:
dhcp-host=08:97:98:XX:XX:XX,192.168.13.59,NITRO,1440m


maybe that is an alternative?

Thanks. I have changed dnsmasq.conf to use dhcp-host instead and it's simplified the overall process greatly.

I have just installed r48646 on my R7000 and was pleased to see the VAP issue has been resolved (I was still using the command workaround, coming from r47608)..

I have removed the commands from my startup script, but the VAPs are not showing on the sys-info screen (they do on my R7800 (Atheros chipset, no startup command required):

R7000:


R7800:


Is this a chipset thing? Should VAPs be showing?

For what it is worth, my AC68U (Broadcom, still running r47608 and startup commands) is not showing the VAPs on the sys-info screen either.
