Samsung Smart TV can't reach the internet
Hi we have comcast business internet the 150mbps package.
A cisco DPC3941B HW Rev 1.0 (that i haven't been able to see connected devices on for months! uhg! pain in the rear)
Samsung MU6290 Smart TV (with the latest firmware and manually defined 18.104.22.168 or 22.214.171.124 or 126.96.36.199 dns)
The smart tv worked fine for 6 or 7 months, then started disconnected frequently, then stopped being able to connect at all to the internet.
If i restart my gateway, the tv gets out for 5 or 6 minutes then stops again.
Is there anything at all in that gateway that could be causing the problem?
I've disabled the firewall on the gateway, i don't have any other firewalls between the tv and the internet. I even tried setting the tv's ip as the DMZ host. The tv connects fine to the cisco gateway's wifi, gets a valid ip, subnet mask, correct default gateway, but fails the internet test and fails to access any internet material (netflix, apps, hulu, etc)
On the samsung side i've tried multiple restart, factory resets, etc.
Samsung is saying that the gateway is blocking the TV (of course) so i have to check with you guys.
If a tech can remote into my gateway and see if its somehow blocking the tv that would be awesome. Tv's ip is 192.168.69.115, mac 682737513c5e.
An amazon fire tv stick plugged into the same tv gets out fine, all my other devices get out fine.
Thank you very much for any assistance.
