But if the problem lies beyond your local network, your ISP should at least be able to tell you the nature of the problem and an expected repair time.After all, a disruption anywhere along the chain between your Mac and a distant server could cause an outage, and its not always obvious where to look.I suggest trying each of the following steps, in order, until youre able to connect again.Try another site or app To make sure the problem isnt restricted to just one website, try visiting anotherpreferably one thats highly reliable, such as Google.com.
If only one site seems to be having problems, try visiting Down For Everyone Or Just Me and entering the problematic sites URL. The service will tell you whether computers elsewhere on the Internet can successfully connect to the site. Use Network Diagnostics Certain types of network problems may cause your browser to display a Network Diagnostics button. This is OS Xs way of offering to help debug your connection problem, and I suggest accepting that help. If you dont see a button, you can launch Network Diagnostics manually. To do this, choose Apple menu System Preferences and click Network. ![]() Sometimes the utility can repair problems itself; when it cant, it usually provides more detailed information about the nature of the problem and offers suggestions for solving it. Macs have been known to hop onto less-desirable networks at inconvenient times. If the menus icon has an exclamation point, indicating that it cant successfully connect to any network, try choosing Turn Wi-Fi Off from the menu, waiting about 30 seconds, and then choosing Turn Wi-Fi On. Sometimes thats the only way to clear wacky errors that prevent Wi-Fi from connecting. Try another device If you have access to another computer or mobile device that uses the same Internet connection, check to see if you can connect to a website on that device. If not, you can at least rule out your Mac as the source of the problem and look elsewhere for a solution. But if the other device can connect and your Mac cant, even after a restart, skip ahead to the step Check your DNS settings. Reset your router For network problems that lie beyond your Mac, if you own or control the network device your Mac connects to (such as an AirPort base station, Time Capsule, router, switch, or hub), turn that device off, wait about 10 seconds, and turn it back on again. Wait for it to power on completely (sometimes a multistep process that can take several minutes) and try connecting again. If theres more than one such device between you and the Internetfor example, an AirPort Express connected to a cable modemstart with the one closest to the Internet and then work your way back to your Mac, cycling the power on each one as you go. Check your DNS settings The Domain Name System (DNS) enables your Mac to convert domain names (like apple.com) into IP addresses (like 17.172.224.47). If the DNS server your Mac uses is offline, slow, or faulty, you may be unable to connect to any site or service by name. Heres an easy way to check whether DNS is functional if no websites, such as google.com, respond. In your browser, type in this URL. If it does, then you know your Internet connection itself is fine and the problem is merely looking up domain names. To fix that problem, open the Network pane of System Preferences and select your network connection in the list on the left. ![]() If those addresses are enabled (black, as opposed to gray), select each one in turn and click the minus-sign (-) button. Then, regardless of whether there are already addresses there in gray, click the plus-sign () button and enter 208.67.222.220; repeat with 208.67.222.222. Bluestacks App Won'T Connect To The Internet Free DNS ServiceThese addresses point to OpenDNS, a free DNS service thats often more reliable than the default servers your ISP uses.) Click OK and then click Apply. Because of the distributed nature of the Internet, an equipment failure at an ISP can affect more than just that ISPs customers. And on a larger scale, accidental damage to a major fiber optic cable can (and occasionally does) wipe out Internet access to a large region. So, sometimes the only solution to an Internet outage is to wait for it to be fixed.
