Router or computer problem?

How do I tell if this is a router or computer problem? In my office, we have 3 computers with a simple windows XP network and linksys router connecting them all. We use Quickbooks, and about 3-4 times a day the 2 computers which do not "host" the company file loose connection with the company file and the software has to be restarted. The connection is fine for the next few hours or so, then we will get booted off again. Now, being that the 2 computers get kicked off at the same time, I would initially think that this is a router problem, however other shares across the network do not get interrupted when the Quickbooks connection is lost (or maybe they do for that split second, but will reconnect without interruption... I can’t tell).

No other network or internet problems seem to be present other than getting kicked out of Quickbooks. I have left messages in Intuits forums asking the same, and followed all their suggestions like company file diagnostics, host and server settings, sharing and etc., and all checked out fine and it was determined it was not a Quickbooks problem.

So I narrowed it down to 1 of 2 possibilities... (First of all, the connection that is “lost” only lasts for a second or so.)
1. The "host" computer (the one that holds the Quickbooks company file) intermittently looses connection to the network for whatever reason
2. The router is intermittently disconnecting all computers from the network for a split second causing my problem.

So how do I tell which one is my problem and how do I fix it?

when you loose quickbooks connection do the other workstations also lose internet access?

I assume you have a network version of quickbooks? How many user licenses?

No! The internet is still up and running. At least I think it is... You see it is very hard to tell the exact time the connection is lost because Quckbooks does not notify us until we try to open or navigate into a new screen. So for example... if the connection (or whatever the problem) is was lost right now, but nobody is actively using quickbooks or the internet during that time, we would not know something happened until the time we try to use Quickbooks. Also the connection problem seems to only last a second or two, so even if the internet was down during the problem, it would be back up and running within a few seconds and to us be mostly unnoticeable in our browsing.

Also, the icon in the taskbar that shows network connectivity and status does NOT indicate any type of disconnection or “hiccup”, if that helps any.

Everything points to only the pc hosting quickbooks being the issue.

Things to check;

power settings on the network interface card should be disabled so "allow this computer to turn off this device..." is not happening

check the event viewer logs on the hosting pc for any errors concerning network/program issues.

This could just be quickbooks crashing. Make sure the drive has been;
run chkdsk /r on the drive
run disk cleanup
run disk defragmenter
