Incorrect DNS configuration?
I recently got T-Mobile home internet. The gateway device is a Sagemcom FAST5688W. When attaching devices to Wifi, sometimes my devices are getting delayed connectivity to the Internet. After investigating the network configuration being provided to the WiFi device from the gateway, I noticed what appear to be DNS servers that aren't responding to queries. Here is an example device network configuation: And here is testing of the DNS servers. The last one is an IPv6 test I believe of the 5688W: $ nslookup > server 192.168.12.1 Default server: 192.168.12.1 Address: 192.168.12.1#53 > www.t-mobile.com Server: 192.168.12.1 Address: 192.168.12.1#53 Non-authoritative answer: www.t-mobile.com canonical name = www.t-mobile.com.edgekey.net. www.t-mobile.com.edgekey.net canonical name = e71824.dsca.akamaiedge.net.
