Hi,
my father has a small office with local network. And suddenly some of the devices can't access network.
It looks like this:
There is a telephone line with ADSL
Line is connected to Zyxel vmg8324 (Modem/Router/Wireless AP)
Zyxel has 4 LAN ports
LAN1 - PC1 connected (it works fine)
LAN2 - TP-link simple desktop switch connected - switch has two devices: PC2 (works fine) and credit card machine (doesn't have access to LAN)
LAN3 - TP-link simple 8-ports switch - 3 devices attached (1 credit card machine, 2 printers) - none of them has access to LAN
LAN4 - free port
There are several phones connected through WLAN.
On my DHCP table I can see just PC1, PC2 and these wireless devices.
I didn't have much time to see everything. I just printed network status from one of the LAN-printers and it had IP starting with 169.x.x.x which was strange to me (it had 10.0.0.x before).
This problem occured suddenly, without us making any changes in LAN environment.
What should I check first? What could be the problem?
Regards,
Bartek
