I have Spark/Telecom as my ISP and I've been having, to say at best, sporadic internet connection. I thought it was just my wifi connection or my phone but it was happening on all of the devices at home. So I did the usual troubleshooting step which is to reboot the router (power off for 30 seconds) - still the same problem. I checked the status connection on the routers WebGUI and I saw that it was a DNS server problem.
To check whether it was a DNS problem, I opened up my browser and checked www.google.com - Web Page Cannot be loaded. Then I tried 74.125.20.191 which is one of the IP addresses for the website google.com - I was able to access it. This was indeed a DNS problem.
As a DNS problem, there are 2 simple temporary (but can also be a permanent) solution.
