Good Evening
I sure hope I do not jinx myself but here goes. After a few modifications, I have been problem free for the past 3 hours.
Modifications:
Computer - Local Area Computer - unchecked IPv6
Router - Wireless: Channel Width 20/40 Auto; 802.11 mixed n, g, b;
Internet Settings - Dynamic IP, Enable ADV DNS Service is NOT checked;
Network Settings - Enable DNS Relay is checked;
WAN PORT SPEED - 10/100/1000 Auto;
Firewall Settings - Enable SPI is checked, UDP and TCP are set to End Point Independent;
QOS settings are NOT modified;
Enable Multicast Streams is checked.
And the time it took to write this up, I am still problem free.

I believe these are all the modifications I made. Also, the Globe on the router is finally blinking so I think I am on the right path (keeping fingers crossed).
Good Luck to the rest of you and I hope things start working for you too.
