Linksys E7350 Internet Problem

I’ve been having an Internet connection problem with my Linksys E7350 router in my room.

My computer can connect to the Linksys E7350 Wi-Fi normally and receives an IPv4 address such as 192.168.1.xxx. I can also access the router’s management page at 192.168.1.1, so the connection between my computer and the router appears to be working properly.

However, when I tested the connection, the router could reach external IP addresses such as 8.8.8.8, but DNS resolution was not working properly. The router’s DNS service returned a “Query refused” error, and using Google DNS (8.8.8.8) directly also resulted in a timeout.

I also tested the same network outlet with another router, and the other router was able to obtain an IPv4 address and access the Internet normally.

Therefore, it seems that the network outlet and the upstream Internet connection are working, and the problem is more likely related to the Linksys E7350 itself, possibly its WAN connection, DNS forwarding, firmware, or configuration.

I would like to have the Linksys E7350 checked and, if necessary, reset or replaced.
