Remediation

poor on Set-Top Box
or network connection
error is displayed.
Wi-Fi signal strength in STB
Network connection menu.
Relocate router and STB
closer in proximity with each
other if possible, such that
signal is strong or very strong.
Connecting the STB to home
router with a CAT-5/5e/
cable will also resolve poor
Wi-Fi connectivity issues.
If video or audio quality
is still poor after network
remediation, contact
OptiLink technical support.
Ethernet cable integrity

is used, reset/replace
Ethernet cable as required.
Router integrity
Power cycle STB and router.
HDMI/Analog composite
cable integrity and
connection
Reset/replace cables
as needed.
TV HDMI port integrity.
Use different TV HDMI
port if possible.
If possible, compare
suspect STB A/V quality
to another STB or a retail
device (e.g. Amazon
Firestick or Roku)
If the STB is found to
show issues while no
other devices do, contact
OptiLink technical support.
