    Another option is to wait to upgrade until Apple gets its act together. I don’t know how many times over the years they’ve released a new OS, and there are wi fi issues. Too many.

      Apple’s flaws only get worse with each passing year. Its golden years have sunsetted and most likely you won’t be getting the fun and functional experience Apple was once known for. Think of Apple as an American car company – was once great but now it’s just a shadow of it’s former self selling mediocrity with a sole focus to reward shareholders.

        I agree. The focus clearly has shifted to the investors and shareholders. The board represents them and they are making the decsions.

      Updated to High Sierra and immediately I got wifiproblems. Attached a cable but it is extremely annoying to see that wifi drops each and every time and nothing helps (no new config, trashing pref-files etc). In this time and age, unbelievable. I was unable to post on an Appleforum. Kaiser-attitudes are growing. The same attitude with the anti-glare coating. How many years in a row does this problem persist?
      I have been using a macintosh for more than 20 years. And I am consolidering switching to another platform as condescending apple has no respect for its customers or users that need to use their machine day in, day out. Just try it without wifi.. writing an article, replying mails, searching the web.. And you need to restart or use an usbfix.

    This mambo-jambo should really not be required. If it worked before, it should work now as well.

      Agreed, but sometimes it appears that wifi preferences get toasted during a system software update which then lead to wireless issues. Usually just ditching them and starting over resolves the problem.

      It seems like this happens to some users with every major system software update, it’s certainly not unique to High Sierra.

      This is simply incredible. When you multiply the number of workarounds by the number of users by the value of their time to the enterprises it is probably billions per act of stupidity. Worse medical offices can not respond, Parents do not have access to information.

      There’s an old Northrup ad totally saturated black page with shinny steel ball bearing – simplicity is the ultimate sophistication.

      It’s time for Apple to stop treating its customers like a pack of zombie gameplayers with nothing to accomplish tomorrow morning.

    I try to solve that problem for the last days. You give me the solution with the removing of some files. Great job thanks

    Thank you. Can you now find a way to get back the Guest option on the Login screen? Mine has disappeared with the new OS, and I can’t get it back through the System Preferences. I liked having it available so visitors could do their homework, job applications etc without me having to worry about them changing my files.

      System Preferences – Users & Groups – authenticate by clicking the lock, then select the Guest User Account in the left hand pane, then check the box “Allow Guests to Log In to this Computer”.

    Just disable airdrop using “defaults write com.apple.NetworkBrowser DisableAirDrop -bool YES” in Terminal and all problems of WiFi will go away. Log out. Login. All good.

      Disabling AirDrop will disable AirDrop, it will not solve wifi problems. Think about it.

    “Down” grade to 10.12.6, all problems gone. Now no video bugs, I can see the login screen, Mail works, no stupid finder problems. 10.12.6 is faster than 10.13. Oh and Server is a server again, iOS/WebDAVS support, SMB sharing without guest access enabled. Apple have lost the plot, concentrating on rubbish with over priced phones, watches and TV programs, all the rubbish to complete the illusion!

    Thank you! This solved my problem. For now. It’s always something with Apple. You know a company has lost its way when even a Genius warns you never to install a new os within the first 6 months of its release (true story – and that was 3 f*cking years ago. You’d think the company would have its act together by now).

    P.S. – why are we forced to listen to Rhapsody in Blue when viewing this page? Really annoying.

    Deleting a kext file from some old internet protection software (NetNanny) MAC did fix the problem.

    From Finder, select Go, and type in Library/Extensions. You will see kext files there.

    This worked for me after trying lots of other things.

    I just added the DNS entries listed above, previously had just 1.1.1.1, and it’s working like a champ.

    Thanks for the tip.

    BTW – don’t listen to the advice about making changes on your router like creating new SSID. There’s nothing wrong with the WiFi it’s a MacBook issue.

    Thank you for providing these instructions. I just applied “add a new DNS” fix and it seems to be working. Need to give it a day to see if it is indeed fixed. Thank you so much!

      Nope, happened again. Didn’t fix the issue for me :(

    I updated to High Sierra and I wouldn’t connect to the WiFi after doing all the methods. I even spent 7 hours on the phone with Apple they did crap. What finally did the job is deleting Adobe

    Tried all the solutions here but none of them worked. The problem was a corrupted USB key attached to the Mac. Once removed everything was fine…

    Not sure if these all in one ports are the best solution.

    The following worked for me on two MacBook laptops!
    First copy data from following folders to a new folder:

    /Library/

    Internet Plug-Ins

    Then delete all content in these folders. Restart mac.
    Speed increase was from 2mbit to 78mbit on an a new mac and from 8mbit to 76mbit on laptop from 2011 on a wifi with 80mbit max download speed.

    If this works for you, this article can be updated !

    I downloaded the Mac High Sierra yesterday and have had constant Wi-Fi drops ever since, one even lasting an hour! I simply could not get back on! Beyond frustrating when you have a project to complete in a short timeline. Unacceptable from Apple.

    I have tried all of these solutions and even most of the solutions in the comments, yet my 2017 MacProBook has trouble retaining a connection to a wifi that all the other non-apple devices stay connected to easily.

    Usually the ProBook connects, and after 5-20 minutes of operation disconnects and cannot connect anymore… I don’t know what to do. I can’t go fiddling around with the routers as no one else in the office has the same problem.

    Have found a solution- am going to Currys/ Pc world to buy a Windows laptop and will dump my useless, pointless and irrelevant MacBook Pro in a drawer until Apple decides to stop peddling garbage to its customers.
    Simply unfathomable amateurish nonsense – this on top of all the obsessive-compulsive tax dodging from the richest company in the world make me not want to come back. I HAVE WORK TO DO AND CANNOT DO IT.

    I have a Mac mini and am having a myriad of problems since I upgraded to Hi Sierra. Biggest problem is connecting to Wi-fi. I tried ALL of the suggestions and nothing works. I don’t know what to do next. I am able to use an unsecure Wi-Fi network (a neighbor’s I think) but I would prefer to use my own secure network. I don’t know what to do next. Oh, other problems include slow internet, no notification banners, occasionally receive error message when I delete a file, sometimes I have trouble closing a page/file and it grays out and I get a spinning symbol and it just hangs. Any suggestions?

    I don’t understand how this fails. I have a MacBook Air that has no issues at all with high sierra, but my iMac just won’t work, regardless of what I do. too Strange, I even tried copying all the network files from the Air to the iMac, but even that did not work.

    I even can’t understand why only some MacOS High Sierra. And also only in some routers. OF Course that’s a compatibility issue, but no make sense you have a computer that works by a chance, when it wants, and no update to fix from the manufacturer. I tried all these tricks but no way to works as should. I wait until end of year for a fix, otherwise my only option is downgrade.
