Hello all... I have a bit more information to add to this "network cable unplugged"
issue. First, contrary to my previous post, Im not convinced that this error could
be due to a "dirty connection", at least on my computer. Reason being: my computer
worked fine when plugged directly into the modem... Its only when the router is in
the loop that the problem exists.
Moving forward, I tried setting the ADVANCED settings for my NIC card to 100BaseTX
FULL_DUPLEX rather than "Auto Sense". This did NOT fix the problem on my machine...
I finally broke down and called D-Link tech support.. After a long wait, I finally
talked to the tech there who recommended that I disable "UPnP" (universal plug and
play) and "Gaming Mode". The UPnP mode supposedly allows your router to be plug and
play compatable, but, PnP doesnt always work well, especially with older systems
and NICs. Upon disabling the above mentioned options, I noticed something interesting.
Before the change, when I would sign into MSN messenger, the computer "hung" for
a short period of time (ie, i could not minimize or move the MSN window). After a
few seconds things resumed normally. However, after disabling the UPnP and Gaming
Mode options, MSN messenger does NOT exhibit this "hanging" and works perfectly.
I have also not had a "network cable unplugged" message since the change. Although
I am not yet totally convinced that this has solved the problem due the fact that
the network cable unplugged error is so intermittant, it may be something for you
to try.
I will wait a few days to see if the problem has truly gone away and let you know...
Info: D-Link DI-624 router, firmware 2.50, Windows XP SP2.
