Cannot obtain a DHCP lease on lan

thing · February 1, 2022, 3:23pm

Good day,

There I was, another normal night for me, when bam, WiFi goes down. My TP LInk-Archer c6v2 seemed fine at first, the lights were blinking, status indicators indicated that there was WAN, LAN and WIFI. But I did not hesitate and pulled out my USB-C to RJ-45 (because ASUS sucks and doesn't have an ethernet port on my laptop model) and went to work!

The first thing I tried was obviously resetting the router. Odd, after resetting the router I still don't get DHCP leases. Hmm, well let's enable the WiFi radio0 802.11nac and check it out...

That's... odd, why is my WiFi interface address in the 172.16.0.0/16 range? Why can't I get any other DHCP leases via wired interfaces? Why does my breath smell? So I started digging more.

A fresh upgrade to:
OpenWrt 21.02.1 r16325-88151b8303 / LuCI openwrt-21.02 branch ... kernel version: 5.4.154

I didn't save any of the configurations I had, but nothing works? Taking a look at the most common configuration files:

Oh the vanity!

If you need anything else let me know!

I would have put more pictures but your discourse server's policies only allow me to post one picture.

frollic · February 1, 2022, 6:10pm

are you sure you're connecting to the right wifi ?

lleachii · February 1, 2022, 6:11pm

What is this?

Yes why...?

You should know. Did you do an ipconfig /all - and see your DHCP server?

That woulda solved the mystery ASAP.

And BTW, it's 172.16.0.0/24 - per the screen.

I didn't wanna ask that.

frollic · February 1, 2022, 6:12pm

and now you don't have to

thing · February 1, 2022, 10:33pm

Are there any actual answers to this mystery?

Obviously, I connected to the default OpenWrt SSID as per having "a fresh upgrade". I should have specified more so that I did not save any configurations but thought it would be obvious given the default configurations for 21.02.1 that were not modified.

eduperez · February 1, 2022, 10:55pm

Perhaps you connected to someone's else router, also left on the default configuration...
Can you watch the logs, and see what happens when you connect?

lleachii · February 1, 2022, 11:42pm

No, that still isn't obvious because OpenWrt has wireless disabled on a fresh upgrade to default configs. In addition the default network is 192.168.1.0/24...and you did clearly state that you didn't save the configs...

Why don't you just the connection Window too...which clearly shows such information...so we can see it then???

We asked you - so who is 172.16.0.1?
Also, by default, OpenWrt's DHCP server would not issue the IP 172.16.0.2 - x.x.x.2 is not in the default scope's configuration
You should now be able to use the arp -a command to get the MAC address
If you do not know how, then use an OUI database lookup tool to get the manufacturer of the device using the MAC: https://www.wireshark.org/tools/oui-lookup.html

You're simply pretending that you're magically getting an address so it must be the OpenWrt...in addition, you're clearly omitting the fact you setup of the device, or are connecting to another AP. Also, the IP is not related to any OpenWrt default config - so it seems counter productive to not assist in your own troubleshooting.

(Please ask how to test further if you do not understand - you need to identify this device, or show us where such a config exists in the OpenWrt.)

EDIT:

I just thought of something else...what IP are you using to access this OpenWrt to copy the configs, reset it to defaults, etc???

192.168.1.1, correct???
If so, what are the results of route print command?
What's on the OpenWrt's arp table (run arp)???

psherman · February 2, 2022, 1:34am

I agree with @lleachii , @frollic and @eduperez that the information provided thus far is confusing and contradictory (and also incomplete).

Here is a really simple test: unplug the OpenWrt router from power. Does the wifi network go down (the one to which the PC is currently connected)? If not, you're connecting to some other device.

thing · February 2, 2022, 3:14am

@eduperez I did not connect to someone else's router because the BSSID that is attached to radio0 is D8:07:B6:21:0D:2A and the BSSID that I am connected to via netsh is:

Thank you for your interest in the logs. The logs that I had posted before were that of last nights logs. As you can see here looking back at those logs there was no assignment of IPs via the router's DHCP server. The client was just connecting then disconnecting, which is weird because on the Wireless Overview page it had shown the associated station AC:12:03:78:B1:E4 being connected but without an IPv4 address. Even weirder was the fact that I was being given an IPv6 address but wasn't able to do anything with it and when looking on the client the IP was a 172.16.0.2 address that wasn't statically assigned.

After power cycling the router once more to clear the log data and get a clearer view of what was going on (also unplugging the PROXMOX server I had connected directly, surprisingly I was able to get DHCP leases.

Now I think I know what the problem is based on disconnecting my PROXMOX server but my question is why would DHCP lease conflicts stop the router from leasing IP's over a wireless radio? Honestly that is why I never considered it being my VM's. Further more why would a DHCP lease traverse past a router into a different network? It doesn't make sense.

@lleachii Honestly dude last night was a late one for me and I didn't appreciate the instant condescending remarks regarding a problem that I had spent over two hours trying to debug. I guess the real question that you'll never be able to answer is why did my router, that was working fine, all of a sudden just decide to take a shit? Maybe if you just asked a question in a better format I would have responded a little less passive aggressive. But I guess this is the internet and you just get entitled twerps that can't deduce simple information.

lleachii · February 2, 2022, 3:21am

???

wow...I just wont' ask at all. (is it the toothbrush joke to the breath smell comment??? totally lost)

good luck

...especially since you failed to provide any information asked of...needed to assist you.

Like a simple one...the IP you used to access the OpenWrt...that really can't be difficult for you to understand...or considered that condensing...but yet you omit it. And I'm sure others wanna know in order to help too...how you accessed a device whose IP wasn't appearing anywhere on the client.

...to others...I hope this is a clue to telling the OP what the issue was!

I actually think you accidentally setup a [working] route loop somewhere..I thought it was rather intelligent actually, I'm lost at how you got condensing anywhere...but then again, you're asking another question now...

...and not wondering how you reached the device...(recall I noted accidental routing)...

Best regards and apologies for any statement you took the tenor as condescending - as none were intended as such.

anon89577378 · February 8, 2022, 7:02am

Looks like they're set on the NIC...

Check the properties page for IPv4 on the Network Adapter for that device (Wi-Fi 3).

There are no DNS entries for interface 'wan'.

No Country Code set in wireless configs.
