Does anybody have any ideas on this?

Why is it that after the host computer Hibernates and wakes up, it can
access Internet but the client computer cannot, unless host computer is
rebooted.

They are connected with 2 NIC's in host and one NIC in client, using an ADSL
Router with 4-port 10/100M switch; also there is a Hub.

So, Line to Router Modem, Ethernet cable from Router modem to Host computer,
Ethernet cable from second NIC in host computer to Hub, and Ethernet cable
from Hub to Client computer.



This is done so to keep the local network behind hardware firewall, so that
files can be shared.



So long as host is not going to get a bit of shuteye, everything is "Honkey
Dory" Can this be fixed?

Regards,

Reima

Reima,

Check the Power Management setting for the host second NIC, and ensure that it's
not set to "Allow the computer to turn off this device to save power".

None of the NIC's has anything like that ticked in PM.
Thank you for trying to help.

Well, that's the most common possibility. If that's not it, verify that you're
actually seeing connectivity loss, or DNS resolution problems. Get PingPlotter
(free) from <http://www.pingplotter.com/>. Install PP on both host and client,
and set it pinging your ISP DNS server. When the client loses Internet
connection (per your observation), see what PP shows.

Say Chuck, the client computer can receive mail with OE but when firing up
IE, it goes to "Finding Site" and comes up with "the page can not be
displayed".

After reboot of Host it works OK though?????

Go figer.

Sounds like an MTU setting problem.

Thanks Chuck, seems I have my day planed now, it'll take a while to
comprehend al that.
Would it have to do with Tx & Rx buffers on NIC's, if so then the client one
has about twice the size of the host's.
Well, I read some more ;-)

Ok, Chuck. I used the DRTCP.exe on the client computer's NIC with MTU Max
size of 1468, after testing with 1500 and going down, that is the max size
with 100% success.

Then I hibernated the host computer for an hour and when it came on line
tested the client's browser and found it working.

So thank you, problem solved.
