After the update Catalina 10.15.7 have problems with the Internet connection

Hi

Can anyone help me please..I have this wifi issue and I need my mac for work. As I mentioned I followed all possible steps written on this feed.

I reinstalled macOS now again and I’m still unable to connect to WIFI.

Could it be a problem that my Mac doesn’t support this newest version, it’s an MacBook Pro 2014.

Can you give me a hint what should I do to solve this or to whom I can get for solving this.

Thanks a lot!

Luis, I am afraid I do not have the technical know-how to follow a lot of what has been suggested here regarding this update to 10.15.7. I just need to use my computer to work from home with various security requirements installed by my employers.

So I am now frightened to go with this update?! I can't afford to take that chance.

GW421, I followed your instructions. My MacBook still will drop network connections. The Internet is SLOW. It does speed up when I close the Mail app.

When it drops the network, it is slow to reconnect and will normally require me disabling WiFi to get a network connection again.

I have two work laptops running Windows 10 beside the MacBook. Both maintain network connections and are operating very well. This is definitely a MacOS related issue.

Are you aware of existing "configuration profiles" on this machine? - It's a Xfinity profile that allows me to connect to Xfinity hotspots. I don't use it often.

You don't need the WD software. - deleted this as soon as I saw the report.

"Memory Clean" - DON'T!!! - OK. I turned it off.

Those internet plug-ins are (probably) unnecessary. Silverlight does not work in any current browser, and you don't need Adobe to read pdf files in the browser. - I removed Silverlight. I'll also remove Adobe.

Like I said, the MacBook started acting normally after I powered it down and let it sit overnight. It's really a shame I can't update it to Big Sur. When it's working, this MacBook does everything I need it to do. I have maxed out the memory and upgraded to a SSD.

Thanks for your help.

I'm wondering if I should start a new thread or continue with this one as I'm back to having the same problem.

I've reboot my MacBook and the router. For some reason, the MB decided that it wanted to be extremely slow with wi-fi. It drops the wifi several times a day. I've tried deleting the network connection and recreating it. I've made sure my location is set to home. I don't know what else to do...I like the MacBook and don't want to buy a new one quite yet.

Well, I was hoping the beta security patch would solve the problem. It didn't. I think the beta has been released.

I think the problem is actually 10.15.7 . When I have my network re-established, I'll restore 10.15.6

I have not tried installing from a bootable installer. I'll give it a try.

I have a Time Machine backup. I could recover to a period when the MacBook was functioning normally. I recently moved and have not set up the network completely again.

After I installed the Safari updated, the Catalina seems to be acting better and not dropping the network as often. I also have been changing the settings on my router, hoping to find a solution.

Yes, I agree. This is the first time I've have a major problem with the OS and the WiFi. You're right. The problem reminds me of problems with Windows drivers. Thankfully, the MacBook is now operating better.

A friend has a brand new MacBook. After the last update, she's had significant problems too. She needs to take the MacBook to the Genius counter, but she's also older. Going into a mall isn't the best idea at the moment.

Good to know you're having the same problem with a fresh install of 10.15.7 . I still need to manually reconnect to WiFi. The MacBook's performance has been degraded.

Apple, may we please get 10.15.8 to fix these problems?

Hey again!

Just curious on who your, (And other’s), internet provider is?

I’m sure similar behavior may happen among multiple. But I just found out recently a possible cause with people using Xfinity internet, and a clear cut fix, let me know!

Hi DiZoe, can you tell me how you fixed it on your system. I’ve tried everything that was mentioned in the threads or other tutorials, nothing seemed to work. I’ve noticed one thing, whenever I restart my laptop and do the speed test in safari , download speed is around 40 mbps but when I test it again it drops to 0.05 mbps within few seconds.

Hi Hamza2331!

I think the issue you’re describing maybe a bit different, is it just an internet speed issue, yet you are able to load web sites?

I can think of a few causes for that for sure.

Can you say what has been done so far for this issue? And if there were any changes made from when it was working, to when it wasn’t working? (Downloads, updates, even environmental changes such as a new router, change in internet provider, a power outage, adding new Bluetooth devices, even a move)?

I think this maybe good for a new discussion, but happy to help out either way, let me know!

Thanks Ken. Interesting experiences. Reminiscent to mine for the MacBook Pros. I can't be certain for the iOS, as I have updated my 1st gen iPhone SE to iOS 14 and haven't experienced any wifi drop though.

Same here. Powerbook updated itself tonight when I restarted (although I didn't want it to) and ever since the wifi has not worked, only connecting for very short periods of time then disappearing again. This is impossible.

I have tried all the “fix” suggestions here in the 10 pages and nothing works. This means I have now lost all saved passwords for many different WiFi connections as a “fix” required deleting all and starting over.

Apple seem incredibly slow to address the problem they have introduced with 10.15.7 How do I go back to 10.15.6?
