Why this config is non-working, and how to correct? (TP-LINK 3220 BB14.07)

laurentppol · August 8, 2020, 10:59am

Hi there,
I tried to modify my (working) routed WiFi config, to bridged one, and this does not work:

Syslog shows EVERYTHING (attach to AP, "IoT" WiFi works ok with ~10 "Tasmotized" Sonoffs, bridge says "port forwarding state") work, but IP doesn't. -> ping 192.168.10.30 (AP "IoT" WiFi IP) goes to nothing (no answer, not even ARP resolved).

When I set it up with WiFi0 as ROUTED, and LAN (br-lan) have 192.168.20.0/24 address (wlan0 192.168.10.55) it looks working.
Where did I mistake and how to correct this?

W want just to set it as "repeater" node, I have similar setup on other 3220 box (only bridge over eth0, eth1, wlan0, wlan0-1) and it works for years.

You pointed me to quite complex setup.
And I can repeat: ""repeater" node, I have similar setup on other 3220 box (only bridge over eth0, eth1, wlan0, wlan0-1) and it works for years". Just ("native") bridge over Eth (all ports eth0 + eth1) and 2 WiFi (ap and sta-wds).

So I am making some kind of stupid error.
Should I clone that other setup, changing only SSID for AP? (and IP for br-lan, of course).

mk24 · August 8, 2020, 3:20pm

Please put your configurations in code blocks using the </> button on the top bar. This formats them in monospace font in a scrollable box which is much easier to read.

It should work to put a STA(WDS) in a bridge, if the other end of the link is a compatible AP(WDS). Are you trying to bridge multiple networks separately or only one? For bridiging multiple networks BATMAN mesh should be considered (even with only two nodes) because VLANs can be run on the same mesh link.

Also version 14.07 is way obsolete and should no longer be used.

laurentppol · August 8, 2020, 3:54pm

Ok (for quotes).
Only 1 (L2) network. As I said earlier, both ends (STA & AP) are in WDS, without this it is not possible to use bridge. And iwconfig shows it is connected!

Should work, (as syslog says), but is NOT.
To the AP in question another 3220 IS connecting as WDS STA, and bridges w/o problem, with its own AP (no WDS), and Ethernet.

If I change IP of br-lan to "lan" and connect Ethernet, it works (ethernet, not wifi), so device seems to be operational.

If it is needed I may post console output (have serial conn to device).

[and I know BB is obsolete, but it fits 4/32 device with all I need ]

laurentppol · August 8, 2020, 4:45pm

Ok, captured console output. Attached.
Looks "OK" but doesn't work.
This is what I don't understand.
Only things change from (working) setup are: SSID, password, IP/default route, BSSID.

As you can see, even ping does not work (nor ARP).
WTF?

Borromini · August 8, 2020, 6:55pm

@laurentppol What mk24 is asking is that you put your original post in code blocks, with separations for each print - so one for your iwconfig output, one for your /etc/config/wireless contents, etc. so people can see what's what.

laurentppol · August 8, 2020, 7:08pm

Ok, look at it now, is that what was I asked for?

Borromini · August 8, 2020, 7:25pm

That looks A-OK

I presume adding a gateway to your network config does not make a difference?

laurentppol · August 8, 2020, 7:48pm

Don't think, but will try as soon as I regain access to device over serial (will replace USB/serial converter as npw it outputs 1-2 lines then nothing, until I exit and re-enter minicom).
ARP did NOT work (after ping arp -n showed unresolved address)

[edit]
Managed to change IP of br-lan, then access over Ethernet / ssh. Definitively bridging is NOT working, as in L2 this device has 2 connections to "main" router -> over Eth (192.168.1.0/24) and over WiFi (192.168.10.0/24). On "main" (WR1043ND with BB too) this one IS listed as "connected client", what is in accordance with iwconfig output. But NO IP over WiFi.

The SHOULD be a "packet storm" as I know about Ethernet (as STP is OFF).

mk24 · August 8, 2020, 7:57pm

Is the AP properly configured? Correct network, netmask and IP?

Use brctl show to see which interfaces are in a bridge. When a WDS STA connects to a WDS AP, the AP's network bridge will add a new interface such as wlan0.sta1 which is dedicated to that station.

laurentppol · August 8, 2020, 8:03pm

The "main" AP IS ok -> works with another 3220 as bridge (WDS), other 3220 as simple WiFi client, 8 Sonoffs as client...
I know about dynamically adding WiFi interfaces to bridge.
But for NOW there is ONLY 1 WiFi iface:

root@Laurent_Home_OpenWrt_3220_second:~# iwconfig

eth1      no wireless extensions.

br-lan    no wireless extensions.

Adding an AP will be next step.

laurentppol · August 10, 2020, 9:31am

Reverted changes I have made:

ssid, wpa_key,
IP, gateway,
SURPRISE it works.
What is the problem (I guess it is located at 1043, config or bug).
Any ideas? (other than trying to migrate "IoT" AP to 3220? (as it serves already as backup link(s) - WiFi to phone and 3G USB modem - I'd like not to modify it's config)

[I have had some other problems with this device - impossible to make work AP (WDS) + STA (non WDS). This config WORKS on 3220.]
