Re: Have a wireless 'always on' broadband system, on a server
computer in
the dining room, being able to connect to internet, (OS is Win XP
Pro).
with a wired Sitecom network 5 port switch system to 2 bedrooms,
working fine
in morning, then in afternoon, computers in bedrooms could not connect
to
internet, the pc icon has the exclamation mark stating not connected,
yet
is shown on the server computer downstairs as connected and working
fine.
Checked all network connections etc, are correct on all computers.
Have
replaced the Sitecom network switch, with a new one. Just to point out
I
cannot use a wireless or router system in the house, having wireless
unit in
computer, coming in from an aerial on the roof. I cannot see the
other
computers on 'my network places', yet says the LAN is connected?
Please, can
someone help me? I am in the process of selling this property and
don't
want it to not go through, because of this problem.
Since this happened, now cannot get online when using administrator
account, yet icons says its connected, but can access the internet on
the
other 2 user accounts, any explanation of this please?
To add to this, in reply to Chuck, giving me good advice, (yes, do
supply
server PC to tenants, free,) was unable to check for a few days:
suggested
I do a 'ipconfig /all' this I have done on server and one other
computer,
(2nd tenant not in house to check hers). Results are as follows:

Doesn't this address indicate that this computer can't find a DHCP server?
Isn't this a default address selected from those assigned to Microsoft for
use in this particular situation?
Jim

Inability to find a DHCP server can come from either of several problems.
# Lack of connectivity.
# Connectivity, but no DHCP server.
# Connectivity, but the DHCP server is busy or not working.

The 169.254.x.x is an APIPA address, assigned by Windows when it doesn't get a
return from a DHCP request.

Can you tell me how I get the DHCP enabled on the host PC? As says it's not
enabled, yet ThuyTran's is enabled, would this make a difference? Thanks
Olim22

The setting "DHCP" means the DHCP client is on. The Network Setup Wizard will
take care of that.

Is 81m111ad the "host computer"? Your terminology is a bit vague. Let's start
by having you run the Network Setup Wizard on both computers. When you run it on
81m111ad (assuming that's the "host computer"), select
This computer connects directly to the Internet. The other computers on my
network connect to the Internet through this computer.

When you run it on ThuyTran, select
This computer connects to the Internet through another computer on my network or
through a residential gateway.

Then rerun "ipconfig /all" on both, and post updated. And please learn how to
copy and paste.
