Smart TV cannot connect to internet via ethernet
-
That pcap was from TV connected via ethernet cable.
My current configuration is such that hard-wired devices receive VLAN ID 10 (from a managed switch). My wireless devices receive the same id from UniFi AP.
Here's capture of when I'm connected wirelessly: https://pastebin.com/9iGnMmAP

Your screenshot above shows the pcap on the "WIFI" interface. It that correct? That's confusing me if so.
-
yes, as of now it is correct.
WIFI = VLAN ID 10.
Over the coming weekend I'll be reconfiguring my switch to have all wired devices to be on the actual
LANinterface (as they should've been).Interfaces / Interface Assignments

Ok so that pcap shows a whole bunch of traffic to different places and on the Ethernet it's not even trying.
About the only thing I could imagine pfSense doing here that could cause it would be a static DHCP lease for the TV Ethernet MAC that was somehow sending it bad values. But the full pcap doesn't show anything wrong with what it's sending.

I just deleted my static lease for wired connection, but the problem still remains...
I can try experimenting later with another small managed switch and force TV to go on another VLAN and see what happens there.
Thank you very much for your help with this! I really appreciate it.

So the wired traffic from the TV comes into the same interface? Same subnet?
Looking at the IPs I guess that must be true.
If the the wifi interface in the TV does not actually disconnect that would present a routing conflict that could produce exactly what you are seeing here.
When it was connected via the Mikrotik were those interfaces also on the same subnet?
I would try turning off the wifi entirely as a test.

correct. both wired and wireless come into the same interface. same subnet. MikroTik was configured exactly the same.
The reason for the new
WIFIinterface name now is because I saw in some video or blog post that separating wireless traffic from wired traffic could make it easier to quickly identify what device is connected to. So, I started doing prep work in pfSense to implement that. As this week will come to an end, I'll reconfigure my switch to map toLANand wireless toWIFIinterfaces. The LAN group has been created to group firewall rules together and allow lan-wifi communication.Just did network reset on the TV and, unfortunately, problem persists (without static mapping).

Maybe check the AP. Make sure the TV is no longer associated with it when it's set to Ethernet.

Interesting thread. I was just trying to fix a similar issue with a Samsung "smart" TV. It just keeps ARPing the gateway, despite the fact that it gets a response. Maybe the response is just too quick for it. It reports connected to LAN but no Internet access.
Anyway, all my web searching leads me to believe that the network stacks in these things are crap.

prefer to keep all my device on ethernet
100% agree. Wired when you can, wireless when you can't.
I did find this suggestion for "disabling" the WiFi (a factory reset apparently won't clear the network config) but haven't had chance to try it:
I was able to turn off my Samsung Smart TV's WiFi by using the TV's Wifi configuration.
Depending on your model and menu functions look for network setup.
Click on set up network or search for new network.
After it searches for available wireless networks chose "ADD NETWORK" then enter a bogus name – a name that did not appear in the selection list.
Then choose "OPEN" for security type. The TV will search for that network you named and won’t be able to connect to it. It will however keep the settings. Once the configuration is finished it will display network address as 0.0.0.0 for all fields.
Turn the TV off. The next time you turn the tv on it will briefly search for the network and when it doesn't find it the wifi shuts off by default. -
@biggsy, thank you for the suggestion! Just went through that and, sadly, same results.
@stephenw10 , Just checked in my UniFi controller. Device is no longer associated.
-
Thanks for trying. Maybe saves me some time on my friend's problem.
-
@biggsy, you bet! But, I still think you should go through the same steps with your friend's TV as well... sadly (or luckily), even if this didn't work for me, doesn't mean that it'll work for you :)

I am soooo sorry to have wasted your time on this issue... Sadly, I have to admit that it was a typical case of PEBCAK.
As I was setting up my UniFi AP, I have changed one of the ports on my switch to receive tagged traffic and I completely forgot that something has been plugged into that port.
I stumbled onto that by finally biting the bullet and switching all my hard-wired devices to the LAN interface. When I went back to my TV to see what's happening, I saw that it was still getting address assigned to the WIFI network. After removing TV's cable and plugging in my laptop into that cable, I was still getting the same subnet IP. Finally, moving the cable to a different port on the switch put me in the proper subnet and TV connected to the internet in no time.
Again, I am really sorry I have wasted your time on this wild goose chaise and a huge thank you for helping me troubleshoot this issue.
@biggsy,
Make sure that your friend's TV is properly wired. Make sure that the cable used to connect TV to the switch/router is good. Get a tester and make sure that all pairs are in proper order. Try plugging in another device into the same network cable that TV is plugged into and see if you get IP in the proper subnet and can access internet. -

Thanks but, yeah, I've already done all that.
Now I'm really starting to suspect that it's got something to do with the device he's using as an AP and switch. The thing just isn't designed to be used that way. It's pretty good as an AP but I think the problem is almost certainly related to having had the TV connected via its WiFi initially and then cabling it to the on-board switch instead.
Glad you got yours working.

No worries, everyone has done that.
It's interesting that DHCP still worked in that situation.
Glad you were able to resolve it!

Thanks!if your friend is using UniFi for all networking purposes (switch and AP), I read on Lawrence Systems' forums that a controller upgrade might be necessary to get this working. Sadly, I'm having a hard time finding that post again. If I will, I'll post the link here.

I found that odd too. I'm not by any means a networking professional - I'd consider myself an advanced beginner, but I do not understand why that port was locked into vlan 10 or how was vlan 10 chosen for devices on that port...
