Clients Network internet connection?

Have a wireless ‘always on’ broadband system, connected to aerial on roof,
(in a shared rented house) on a (free to tenants), ‘host’ computer
downstairs, (with OS Win. XP Pro. SP2 installed), supposed to be able to
connect to internet. Host PC connects to internet okay, clients supposed to
connect to internet with a wired Sitecom network 5 port switch system to 2
(client) bedrooms, (from host pc) worked fine am, but late pm, client
computers could not connect to internet, the LAN PC icon has the exclamation
mark stating not connected, yet is shown on the host computer, as connected
and working fine. Checked all network connections, cables been checked as
correct, replaced the Sitecom network switch, with a new one, network set-up
wizard done again, on all computers, re-started. (Must point out I cannot
use a wireless or router system in the house, having wireless unit in host
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? My husband
died last November, used to be able to sort it. Some more information to be
help anyone sort this problem out please. (sorry Chuck, had to enter new
thread again, not in same thread, as we communicated so much, other one ran
out of space! (Have included everything you suggested me to try & give you),
please, if you can still help me, or anyone else?

Sitecom Network Switch information:
PWR LED, indicates power is present (red light is lit)
P1~P5 LED (LN-112), port status LED’s indicating the status of each of the 5
ports. Green light is lit on 3 ports (ones used).
Speed 100 Mbps LED, A green LED indicates if the speed is 100 Mbps. This is
lit.
Link/Activity LED, when the LED is lit, then there’s a link, when the LED
blinks then there’s activity. (green light lit, but NOT blinking).

The ipconfig /all done on the 3 computers:
