Slow wifi after Big sur update

Jens,

That's great to know! Since the issue happens with uploading to your NAS too, we recommend reaching out to your internet service provider to have them look into things on their side. If they don't find any issues, reach Apple Support to look into this more. They can be reached here: Get Support

Thanks again, and have a wonderful day.

I'm having the exact same issue - have tried all the steps, including booting from a USB to an older version. The older version works great, Big Sur does not! Currently, running 11.2.3 on a clean install new MacBook Pro.

I just set up a new Macbook pro (16in) today with 11.2.3 and this is still a problem.

Internet was great on catalina before I upgraded. Upgraded to bigsur and the WiFi internet is absolutely terrible.

I went through the recommended steps to solve this problem, but nothing helped.

When will there be a solid solution for this apple? It's quite disappointing, I can barely use the laptop with speeds this bad.

Hi,

I know found a workaround for this bug. As soon as I disabled „Unlock with Apple Watch“ and then did a restart the issue never came back. I now have constant wifi speed from 550-700 Mbit/s. With „Unlock with Apple Watch“ enabled I only got 250-300 Mbit/s (so only the half).

Maybe you could give it a try.

And yes Apple still has to fix this as I already miss this great feature unlocking my Mac with my watch.

I‘m curious if this workaround also fixes your wifi Problems.

I’m having the same issue on a macbook pro 16”. After system restart the wifi speed is around 800 Mb/s (I have 1 Gb/s connection). A few hours later the speed goes down to around 200 Mb/s. Common Apple, I spent a lot of money and I want a decent wifi speed. I’m 100% sure it’s related to macos issue - I’m also on Big Sur. The connection speed is stable on my iphone x. I have the unlock w/ apple watch option enabled, but don’t think that it makes any difference.

That makes sense, as unlock with Apple Watch also uses Bluetooth. I’m also experiencing Wifi issues on my iPad, with the same speed drops. As soon as I disable Bluetooth on my iPad, it also has normal speeds.

Disabling this feature is not an option for me, since I find it very convenient and that’s why I purchased a mac to have one ecosystem. I also use a magic mouse so if it’s a bluetooth related issue it won’t make any difference. I bought a hub with ethernet connection, but it’s extremely annoying having such a bad wifi speed on a such expensive laptop.

I completely agree to you. I also want Apple to fix this annoying bug as I really liked this feature.

Maybe you just could deactivate it for a single day to test if this is fixing the issue. Then maybe we could pass this feedback on when making a phone call with Apple support.

I tried this in hope to enable unlocking with my apple watch again, but now my download-speed ist down again. The apple watch workaround worked perfectly but now I can't get it to work again. :-(

My conclusion: If the apple watch workaround worked for you then don't touch it...

I tried all of the recommendations, and some may have helped a little. It was had to tell with so many. But the one that absolutely worked was simply turning off my Bluetooth. Not the ideal fix but it worked. I have a 200gbs internet and it went from not even able to bring up the speed test or occasionally 10 or below to 215-225.

OMG - I'm so relieved that I stumbled upon this thread and confirmed my suspicions....

It took me a week, to test EVERYTHING I could think of, with multiple routers and Wi-Fi standards, countless hours spent on forums, just to end up with the same conclusion I came up on day 1 - it's on Apple's Side - not the internet provider, not the router - just Apple messing up Wi-Fi and Bluetooth frequencies....

THANK YOU EVERYBODY, for jumping in and providing your feedback and the workarounds - you're AMAZING! I can finally relax and sleep like a normal person)

Now, it's time for APPLE to take action and finally fix this - we don't need you to confirm our workarounds, we need a SOLID FIX that ensures STABLE and MAX connection with our devices.

If my iPhone 12 Pro and ASUS RT-AX55 support Wi-Fi 6 - then I should be getting the 700-800mpbs that I'm paying for. My ISP provides 800mpbs, confirmed by Ethernet on both - Mac and Windows - so I should be getting at least 700mbps on my iPhone 12 Pro(Wi-Fi 6), iPad 7th Gen(Wi-Fi 5) and MacBook Air 13 Retina 2018 (Wi-Fi 5). Currently, I cannot get over 450mbps on iPad and MacBook Air, iPhone 12 Pro goes up to 550mbps, if you switch to AX Settings only. The settings are CORRECT, so please don't bother asking for them - all according to your recommendations. However, if you really NEED them, then PLEASE do ask for specific ones, instead of generic troubleshooting steps - like the distance of your router, restart your mac, etc...

So now, the only question remains, when are you going to acknowledge this BUG and provide a FIX for it?

unreal, i was using my download speed on macboook air 2017 all the time with not even 1/3 of speed until i realize there is a problem with Big Sur.

I have 60mbit download and 20mbit upload with my Hybrid Router connection, and works fine with all devices just on macbook air i got max. 15mbit download ( (after restart up to 22mbit for 10min after that again 15mbit) and upload was always fine about 20mbit. So the problem is only with download speed.

After reading the solutions here (i have no energy save option, i have no apple watch) i just turned my Bluetooth off and yes it works perfectly now with full speed 60/20.

unreal apple didnt fix it, For "Big Sure" there is a problem with OS.

thank you guys

I have the same problem with Macbook 12inch after updating to Big Sur. Have sympathy with me - I have a 20mbps contract that is now down to 1 or less mbps!! I have done everything - read through all the comments, rebooted, deactivated apple watch, switched off bluetooth, updated latest software,Tech guys opened Macbook and reset, etc, etc. iPhone and iPad work perfectly - just the laptop. Please Apple fix this bug.

Thank you very much for your help !!!I struggled with this problem from the beginning (MacOS big sure) omg finally I can watch 4k movies from synology,nobody was able to help-technical support always invented other reasons !!!!!! I was about to buy a new router thank you again you are the best !!!!!

This!!! This absolutely solved my issue straight away within minutes. I live in the Middle East so my wifi is naturally at 40-50 mbps, but with the new update, it was as slow as 2mbps, after your helpful response, it went back to its normal speed.

Thank you!!
