Hi,
Just wanted to say thanks :)
I used this as the basis for adding a second tp-link wdr3600 in my home network.

Regards

I landed on this page after I found my printer couldn't be seen from the LAN wired side of my "Dumb AP". After some searching I found this page and turns out I was missing the bit about dnsmasq, turning that off fixed everything, thanks!

uci commit dhcp; echo '' > /etc/config/dhcp
/etc/init.d/dnsmasq disable
/etc/init.d/dnsmasq stop

Just what I was looking for... except, I'd like to make use of the DumbAP1 as my DHCP server. Should I just comment out the Disable Dnsmasq section? Thanks heaps.

Sorted that - best not to delete it in the first place: but otherwise, copied back the default /etc/config/dhcp plus some tweeks; enabled dnsmasq; disabled firewall - correct me if I'm wrong, but I can't see the point of a firewall in a (not quite so) dumb AP; also deleted wan6 as per deletion of wan

First of all, thank you very much for this tutorial!
I have 3 Archer C7's waiting to be installed (OpenWRT is already installed), but I'm waiting for the contractor to clean the pipes for my wires (the builder poured concrete while the pipes were still open...)
As soon as this is done, I will start configuring them, with this tutorial.

I just have one question... I noticed:
uci set network.lan.broadcast='192.168.0.255'

While the rest of the config points to the 192.168.1.x subnet, the broadcast here is 192.168.0.x
Is this done intentionally or, is this a typo?

@ShapeShifter499 Glad that this helped you!

@xpseudonym yes.

@D2nnyim yes it was a typo! thank for noticing, I corrected it now.

@AlMoselly I don't know what it could be doing that, please try to debug it using logread, see if you have more than one router maybe with dhcp enabled, you may have your ISP router with ipv6 dhcp connected to the lan, or may be just that device that have separate config for ipv6.

@braian87b thanks for helping me out with this instruction, I had used it for my 841ND to bridge multi router at my home. The problem is the openwrt act as it is invisible in the network. You cannot ping it at 192.168.x.x as you has already set. I had followed your command above as well as instruction with Luci in the main page of openwrt. The bridge does it job perfectly but I cannot control it anymore. Do you have any solution for that?

It have no ip address in the network, which means you cannot go to luci page or even get ssh connection to the openwrt

This config steps are for configure a Router as DumbAP and connect it to your existing LAN with an existing Main Router using an ethernet cable (wired).

On the Lan interface on the DumbAP you can set a fixed IP (on the same range of your existing network) or configure it as DHCP (to get an ip automatically) if you have it automatic you should scan your network (using nmap or some other ip scanner) or watch the dhcp leases table on your main router.

Please see relevant lines on this again, are 17 to 23, and 25 to 31 you should run just one of those depending on what mode you choose, not both.

Thanks for your response. I just copy it to a bash script and run. I don't even read the comments. My dump bridge now run as good as what it's supposed to be!

I have done this before and thought I knew how to get the router running as an AP, but running diagnostic I still have 100% packet loss. I have disabled firewall, disabled dnsmasq, set static IP and turned off DHCP, but still I have 100% loss. But, the device is connected to my main router and is online. I can connect wirelessly through it and openwrt.org is there. But when I attempt to ping or update software list for adding samba, it fails to connect. Also, I basically did all this 4 days ago using ROOter firmware and pretty quickly had it connected and ping received 100% easy peezy.
