Lower internet speed after 2011 Software Version Update

[Oled 65 Streaming]

After last week’s update (Version 2011) my OLED TV registers 91Mbps instead of 300Mbps while using Samsung Internet browser. This creates streaming errors in apps like Sling and even in Samsung TV Plus. Either wired or wireless.

I’ve done a factory reset and issue remains. But now I can’t even use the Device Care option within the Support section as it displays message “This function isn’t available”.

You can only use the Device Care option when using Samsung TV Plus or any active input signal (Antenna, HDMI, or USB-C). After switching to one of these sources, run Device Care.
(We recommend running Device Care on the input signal you want to troubleshoot.)

Thank you for the reply regarding Device Care.

i reached out to Samsung Technical Support and after running remote troubleshooting they have dispatched a tecnician for onsite support next week to address the streaming issues.
