Ah, yes, it is good to be sure you are actually using your own home network! I am in a multi-family dwelling (condo apartment building) and I have my network locked against intrusion by others and also my computers and other devices are all automatically set to access my own home network first.
Yes, they are. Who knows if I had a spell and absentmindedly switched things. (I suffer some kind of seizure activity....)
A question has just occurred to me: don't you have your computer set up so that when you turn it on it automatically connects to the internet anyway? There shouldn't be any effort to "go to the internet," it should be an automatic process that when you first turn it on, your computer connects to your ISP/the internet and then when you're ready to look at your email or to go to a website it just goes wherever is you want to go..... For example, when I first turn on my computer in the morning the machine boots up (usually I'm in the kitchen making my coffee and pouring my orange juice) and when I come back to the computer it is ready to go where I want to go, do what I want to do. I usually check my email first and then I move into checking and participating in my various forums, including this one.
Yep, it's connected always. Unless we have to turn off the internet because of a bad storm. (To avoid frying to router.... again.)
Very rarely there have been issues with going online and I usually notice those pretty promptly when I've booted up the machine and then gone to check my email. Ah, if there is oddly no new mail showing up or when the expected page via a bookmark that I have clicked doesn't open..... I see that there is a problem. Also if Safari in general doesn't open with my usual Apple News page. Sometimes a reboot is all that is needed, maybe something just went glitchy during the original boot up. I glance at the router to see if the light is green, meaning all is well. If not, time to move to the next step. Sometimes I reboot not just the computer but also the router and the modem in case that is the problem. At other times (more common) it is an issue with the ISP, especially if we are having bad weather. No matter what I do on my end it is not going to help until the ISP resolves the problem at their end. Checking my iPhone or iPad will verify that the issue is widespread, not just limited to my computer. It is frustrating and annoying when this happens but since I have cellular data on my iPhone and also on the iPad, I can still get online anyway. So for me, first line of attack is to reboot the computer, and if that does not work I check both the router and the modem and reboot them as well. If it is clear that weather conditions might be causing issues with the ISP I don't worry a whole lot about it and know that my connection with the internet will be restored eventually......
