Apparently, something is blocking DNS Server access from the TV, BRD and the
WD Live and keeping them from accessing the internet when plugged into the
LAN, and in the case of the WD Live my shares. Any ideas on solving this?
I know I am snipping a bunch here but here is the troubleshooting I would
do:
1: Ping the devices from your LAN using various packet sizes to see if it
is an issue with packetsize.
ping ip.address.of.device -f -l 1472
The -f means do not fragment, then -l means length, 1472 is the maximum
MTU the ethernet generally uses (1500 which is 1472 worth of data and 28
worth of packet header)
Assuming you can get packets through and get responses with that command
you can pretty much assume the network itself is working ok, because it is
passing the largest packets you can ask it to.
Further tests would be to attempt to use a known good public DNS server
(4.2.2.1 is one I use to test DNS issues).
2: Try switching out the cable going to that switch
3: Try switching out the switch itself
4: Examine the arp table on your local LAN, do you possibly have a
duplicated MAC address for one of the TV's? Unlikely but possible
