network problems

[Guest]

hey

I've had a d-link router for awhile now, and it worked fine. Lately though,
one of my two connected pcs, I would randomly lose connection and regain it
after an hour or so. A few days ago, I lost connection again and it hasnt
returned. I checked the network folder in control panels and I have four
connections. Local Area Connection 1, Local Area Connection 2, 1394
Connection and 1394 Connection 2. Ive figured my problem might be a result of
all these conflicting. Yet I cannot delete ANY of them, and can only disable
the two local area connections. I recently had a virus problem and im not
sure if this could be in any way related. Does anyone have any suggestions or
precedence to help on? or maybe just how i could get rid of the exta
connections? thanks.

AJ,

If your problem was indeed, as I read (please correct or verify):
1) The problem started out intermittent, and on either one of two computers.
2) The problem would be on one, but not necessarily the other, simultaneously.
3) The problem would come and go without any action on your part, or pattern.
4) The problem is now total and does not go away.

I don't see extraneous connections as being the primary cause of the problem.

Intermittent, and gradually worsening, problems are generally caused by:
1) Hardware failure.
2) Malware infestation.

My money would be on #1, at a 2 to 1 ratio. How are the two computers
connected? Thru a router, in which case can you access the router? Or is one
directly connected, and the second connected thru the first?

Try this web page to see if it's a problem with network equipment on either
computer:

I apologize that my original post wasn't clear. The problem did not alternate
between the two pcs. One of them has always been and continues to be fine.
The other one would from time to time lose connection, and then regain it.
Although it has not regained it this time. I have used Adware and HijackThis
to scan my pc and it seems to be clean, although im aware they dont give
perfect results. The suggestion that my network card died has been mentionned
to me by someone else also, and it seems plausible, althoug the pc is
relatively new (about 2 years old) if thats the case, how might i check this?
Although i remain decently sure that its something within my pc blocking the
connection. Thanks.

OK, thanks for clarifying things a bit.

So the cause is almost certainly isolated to the one computer (or maybe to the
device connecting the two). Is it a router connecting the two, and if so, can
you swap router ports and cables?

If you ran HijackThis, did you submit the HJT log for expert help (if so can you
post a link to your expert help posts), or interpret it yourself? Doing it
yourself is doable, maybe some more help would be useful:

Did you run hardware diagnostics on the network card? Device Manager is under
System Properties - Hardware. Device status, and the Troubleshoot button, is on
the General tab of the Properties wizard for the network card.
