Hi
I am glad that you solve your problem.
However your explanation is somewhat lacking to in describing a solution to
such problem.
A Router is a combo unit of Routing circuits, Wireless Access Point, and a
switch.
There is No difference between the switch inside a Router and a stand alone
None manage switch.
It could be that your switch is Not doing so well any more, and it could be
a general mismatch in your Network.
In many cases switching to Force Full Duplex can hinder None Pro Network
rather than Help.

I had a similar problem and found the fix. The issue: Windows Vista
machine connected to Linksys 8-port gigabit switch. The switch is
connected to a router (of course). All other non-Vista machines
connected to the switch worked fine. But, the Vista machine displayed
"network cable unplugged" message when connected to the
switch...however, it worked great when plugged directly into the router
(same cable used when connected to router and switch so I KNEW it was
NOT the cable). There were many suggested "fixes" out there, but the
ONE that worked was... Control Panel / System / Device Manager / Network
Adapters / Right Click on your network adapter / Properties / Advanced
Tab / Speed-Duplex Settings----CHANGE THIS SETTING TO "100 Mb Full
Duplex". The "Auto" setting apparently does not work when the machine
is connected to a switch. I don't completely understand why this
worked...but it did work!
