IMAC NO INTERNET CONNECTION PC
First, go to the Apple menu, System Preferences, and then Network. Make sure your iMac is on and running Windows, then connect to the same network as your PC via Ethernet or WiFi.The good news is that there is a pretty reliable way to resolve the issue. Mac users often encounter a situation where WiFi doesn’t reconnect properly after waking from sleep mode. You can use a WiFi analyzer app on your smartphone or computer to see which local WiFi networks are using which channels and then set your router to use a relatively uncontested one. Even when traveling thousands of miles from home in developing countries, most businesses, homes, and even public spaces are equipped with modems that broadcast wireless internet. Most of us take the always-on Wi-Fi connectivity for granted.
Channels 1,6 and 11 are popular choices for the 2.4Ghz band because they don’t overlap. All of a sudden, you can’t make progress or even start on something without an internet connection. However, a router can have its channel manually set or that, for some other reason, there’s just too much competition to find a good channel. So, usually, your neighbor’s router will automatically use a channel that doesn’t have anything else happening on it. There are 11 and 45 channels on the 2.4Ghz and 5Ghz frequencies respectively. When I click on the Wi-Fi icon from the menu bar, it. Wi-Fi icon in the menu bar has a line through the Wi-Fi icon. I am having the same issue on my iMac (Retina 5K, 27-inch, Late 2015). To connect to a Wi-Fi network, click Wi-Fi in Control Center or the menu bar, then choose a network from the menu. At first no network appeared and now even though it has connected silently to my usual network, it is showing as no connected, but internet actually works. All WiFi systems operate at the same frequencies, so why don’t they clash with each other? The answer is that they use “channels”, which break up the main frequency into small, narrow channels. To connect to the internet over Wi-Fi, your Mac must first be connected to a Wi-Fi network, and that network must provide a connection to the internet.
