my DNS server keeps changing
My DNS server keeps changing to 10.xx.xx.xx when it should be 192.168.1.1
I cannot access the internet when it's connected to the 10. I'm running High Sierra. this problem started shortly after I purchased my laptop. I have removed the Wi-Fi and rebooted, then re-added. Sometime sit works and is connected to the 192, but sometimes not. I cannot continue to do this and need a fix.
Also, my router changes to 10.0.1.1 or the like. I have no clue why. Please help!
Thanks
