New pfSense Install Issues with 1 of 3 Samsing TVs. Cannot establish an internet connection
-
I neglected to write that down in my notes. I think it was dynamic DHCP when I switched to wireless.
No 'ARP Table Static Entry' Deleted that early on. It did not help at that time.
TV Clock has always been set to auto and the correct time zone. FYI:It does not have any time server settings that I can find.
But I would have thought that the TV clock would have corrected itself during the several times it was connected directly to the Modem, had an internet connection established and was streaming anything. Also, shortly before I moved over from my old firewall, it was working and the tv was not power cycled until I started the debugging. It should have had the correct time.
The capture log timestamps look like they are UDT, is that normal?
I do not have the pfsense NTP service enabled because it says not to if is running in a VM. How ever I did make the localization entries in the General Setup when I installed pfsense. I'm running pfsense as a VM in proxmox and it has had the correct time.
Does any of this info help? Thanks!
-
Probably not a clock issue then.

Any suggestions for next steps?
Thanks

Is it still working correctly? Not sure there's anything we can do if we can't replicate it.

This feels like once it was able to connect it may have updated and corrected whatever issue it was hitting
But why wouldn't it have done that when he connected it directly to his modem? maybe he didn't leave it connected long enough?
Its still arping like crazy - every 2 seconds
That doesn't seem right... Do your other tvs do that much arp?
So I took a look at one of my tv's and how much it is arping, and MY TCL tv is arping for its gateway every 12 seconds.
Its better than every 2, but it still seems like a pretty insane amount of arp.. Do these IOT sort of devices not have any cache at all?
-
Mmm, that does seem pretty crazy.
-
@stephenw10 It seems a lot of people have noticed the excessive arp from my TCL and Rokus seem to do the same freaking thing..
But have yet to find a way to change the frequency, nor an explanation for it - other than just horrible coding?? Why should a device arp that much? Can't you cache it for even 30 seconds? Man if you put a lot of these devices on the same network, and lets say it was wifi - that would end up being a large portion of traffic for zero reason that I can think of..
Do you think the mac of your gateway is going to change that much that you need to arp for it every 2 seconds, or 12 even?
This is my Harmony Hub, its a bit better at ever 30 seconds..
-
Yeah I have some thing at 30s. I highly doubt this is anything malicious. Almost certainly just lazy code.

@stephenw10 Yeah agree I just think its just bad coding.. If you have a few devices, no big deal I guess.. But was at a bar yesterday to watch some of the madness.. They have 60+ tvs.. All of them arping every 2 freakings seconds - heheh that would be nuts..

@johnpoz I just saw this post and am having the exact issue with two Samsung Smart TVs. They sometimes connect wirelessly to my network (behind PFSENSE and PIHOLE), but they continuously report they are not connected to the internet. Sometimes they report they are not connected to the local network. Very odd.
-
Are you blocking or redirecting traffic from them?
-
@stephenw10 In the tail logs, I can see zero blocked with anything to do with Samsung. What is really odd is that sometimes both TVs reports they cannot connect to WIFI and other times they (multiple) reports local connection only. I have rebooted, repowered, turned off blocking, etc. All same behavior. Next step will be to bypass pfsense.
-
If they're actually not connecting to WiFi that's a lower layer problem. Are they both connecting to the same access point? Can you test a wired connection?
-
@stephenw10 I will tomorrow and report back. I believe, however, they are trying to contact some samsung server somewhere to determine if they are on the network. Will advise, thanks for helping me think about what is going on here.

well out of the box pfsense wouldn't block them from talking to anything on the internet. Are you filtering outbound traffic in someway, dns with pfblocker or running IPS?
-
In my particular case I found it was because of Kea DHCP server.
Samsung TV (UN58TU7000FXZC) would no longer connect to WiFi (UniFi U7 Pro AP).
As soon as I put back ISC DHCP instead of Kea it worked.
-
@judesro kind of hard to talk to something on the internet with out an IP
-
Hmm, I have no explanation for that. Were there any errors logged?
-
@stephenw10 not that I am aware of, but I am not that familiar with Kea logs..
That's what was shown in the logs section. Looks like the lease was given repeatedly from the router point of view...
-
Mmm, nothing terribly exciting there.
