Just today I was given a newly provisioned static IP by my ISP to see
if that fixes anything. In the process it was discovered that my
Gateway IP entry was incorrect, one of the DNS IPs was listed instead
(IP forwarding must have been on for this to have worked at all). Until
the weekend arrives I will not know if things are better or not. Tech
support gave me the wrong Gateway address some time back, but that may
have been during one of my dropped connection complaints.

You asked for the "exact" symptoms--
During email or web activity I will simply lose the connection (very
annoying when in the middle of an online purchase). I can ping the
router (using the local 192.168.1.1 address or the static IP assigned
by the ISP) but cannot ping anything outside (none of the IPs for DNS
or Gateway). When I depress the reset on the router or use the router's
webpage interface to re-apply the settings, I almost always get the
connection back and can continue for another web-link or two before it
happens again. If I go away and come back in an hour I am successful at
refreshing my home page (one way I check for internet connectivity),
but that doesn't last long (same as resetting the router). When I am in
one of these "flakey" periods (e.g., weekends) I can run the ping
command for 25 consecutive retries and I will lose my connection during
one of the pings... so even tiny packet activity can experience this. I
have experienced the problem with only wired PCs connected to the
ethernet ports on the router (i.e., no wireless laptops in use). Here
are some questions I have in response to your reply:

Question1: can radio interference cause problems with my
4-port+wireless router, even when the only connectivity I have and am
using is wired?

Question2: Can you explain more about the file sharing problem? I don't
do much with file sharing at home and the problem I experience is
certainly not only occuring with file sharing activity. I do have a
shared printer set up and a shared folder on the primary PC near the
router... but I am sure I have had that PC powered off and still
experienced the problem from another wired PC (a Mac) or wireless
laptop (Dell) that was not involved in sharing or printing. I think it
is rare that I use file sharing to transfer files between PCs at my
home... but I do have a pub folder for those occassions.

Question3: I have a Mac in a different part of the house connected to
one of the ethernet ports on the router and this machine is rarely
turned off. Could the length of cable be an issue? I am pretty sure it
is under 100 meters long.

Thanks.
JJ
