<p>Have you tested all switch ports with both computers?<br>
I had a netgear adsl modem/router/wifi which had its ether ports gradually go out after almost a year of perfect operations. I had it replaced under warranty.</p>

<br>
I have a typical home network. In one room, I have several computers, so I<br>
want to use an additional switch there. I got an EDIMAX ES-3208P 100 Mbps<br>
switch (90 shekels, at Bug).<br>
<br>
Now, what happens is that while my wife's Windows computer works well with<br>
that switch, my Linux computer does not. Sniffing the network, I see that<br>
my Linux computer sends out DHCP broadcasts (to get an IP address from the<br>
house's DHCP server) or ARP broadcasts (to contact the gateway), but while<br>
replies for these queries are being generated, they are not forwarded by the<br>
switch to my Linux computer!<br>
<br>
When I replace the switch with a 10-year-old hub I had lying around (good<br>
thing I didn't toss that museum piece), suddenly everything works!<br>
<br>
I could have concluded that that EDIMAX switch is simply broken, if it<br>
weren't for the fact the Windows computer works perfectly behind it! What<br>
could possibly be the cause for the Windows computer to connect correctly<br>
behind the switch, while the Linux computer doesn't? Has anyone ever seen<br>
such a problem?<br>
<br>
Thanks for any ideas,<br>
Nadav.<br>
