Unable to resolve local hostname when WAN is down.
Hello TP-Link Community,
I recently set up a network using the ER7206 router, SG2428P switch, and OC300 controller. However, I've encountered a recurring issue: when the internet goes down or the ISP's DNS server fails to resolve domain names, my entire local network is unable to resolve the hostnames of devices on the same subnet/LAN.
This issue disrupts file sharing and printer sharing in my office, and the only way to connect to other devices is by using their direct IP addresses.
Can anyone explain why this happens? How can I configure Omada to ensure that LAN file and printer sharing work regardless of the internet connection status?
Thanks in advance for your help!
