Active network services consume a portion of the available bandwidth. Examples of these include file servers, video streaming, online games, and so forth. When these are in use, they may cause other services to slow down. Try turning off unused network applications to increase the speed of other applications. Be aware that other computers or devices connected to your network may also contribute to poor performance. If you are not sure if a computer associated with your Wi-Fi network is causing poor performance, try turning it off or disconnecting it from the network.

Use WPA2 Authentication, if available. The WPA2 authentication mode meets the highest standards for Wi-Fi compliance and should be used to provide the greatest speeds for modern Wi-Fi networks. Other authentication methods may reduce performance of your Wi-Fi network.

In order to change the authentication method offered by your Wi-Fi router, you will need to contact the manufacturer.

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. Really annoying. I just fix it the issue at the moment Turing off the bluethoot.

So this article is about High Sierra network prefs but the author is using pictures of Sierra network prefs… smh. I just added the DNS entries listed above, previously had just 1. Have had wifo problems since on my imac, today it has dropped over 12x! Im about to just get an ethernet cord and a separate modem!

So tired of this. Thank you for providing these instructions. Need to give it a day to see if it is indeed fixed. Thank you so much! 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….

The following worked for me on two MacBook laptops! First copy data from following folders to a new folder:. 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 on a wifi with 80mbit max download speed. 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!

Deleting preferred wireless networks on Mac OSX

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 MacProBook has trouble retaining a connection to a wifi that all the other non-apple devices stay connected to easily. 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 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. Any suggestions? And also only in some routers. 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. I agree, it is sad that I spent over 2k for a computer that cannot make a simple Wifi connection. My Raspberry for less than 80 bucks does it without special code. If anyone is interested, I created a script that you can add to your login applications. Just save this with the automator.. I think the programming error is made with machines that have both en0 and en1 devices, not ones with just a wireless connection, both as default and only connection.

I will wait for the next version of macOS for a resolution. That appears to be the only option. I still have Sierra So I had to go through and delete my preferences and delete my location and all that. Happy New Year. In my case, not only is the Wifi connection lost repeatedly, but even a wired NIC connection is going up and down.

Trying to contact Apple support, but only ever get a promise of a chat session that never seems to materialise. Maybe I should investigate taking legal action to recover lost earnings due to wasted time? Really Apple its probably juts hypoxia. I have tried all of the above, nothing works other than re-logging into my network every time my iMac wakes up.

The upgrade worked fine on my MacBook, but the iMac fails every time. This website fixed all my problems thank you so much I was about ready to throw this computer across my room. I have been troubleshooting for weeks at different customers and found that it seems to been problem against AP with AC Wave 1. Even better with Yosemite HP with Intel AC card has no problem at all. Expected speed at speed test and not a singel ping loss.

This all happened overnight after upgrading to Feel terribly betrayed by Apple…. Thanks to http: He warned of the possibility that the wifi network card will not be usable after the update with his patcher. This did not prevent me from installing High Sierra. Well guess what the network card is not usable anymore.

Ok first I did not mind till I realised that Philips Hue only interacts through a wifi network and not over bluetooth, which I first assumed. I have been searching for wifi dongles that are compatible with High Sierra so far without success. Has anyone found a wifi dongle which works? I went through keychain access and tried all options but the 3rd listed to no avail. Something about inputting the airport name myself made the computer remember the network. Hopefully this helps some of you. Finally fixed with version Thanks Apple.

Now if only my iphone would work like it did when it was new…LOL. I am on I have tried to get ATT to fix.

Some of the techs can but it does not last and has to be done multiple times. I am goint to try the patch above and see if it works. It is sad that a high end computer with the most recent os macOS High Sierra Thousands of dollars lost. I hate Microsoft but Apple is going down that road and it is not going to be good. If Apple is the same as Microsoft why spent tripple or higher for junk. Just an update. Disabling ipv6 didnt work for me. Go to the DNS tab and from the left column delete everything. Then add these two DNS addresses, in separate spaces:. So none of the above worked for me.

I then tested by restarting the laptop and waking from sleep. I also switched off and on WiFi from the network interface.
