Internet connectivity issue since upgrade to PD 18.x in my Windows 11 VM

[Pramesh Boodadoo]

This happens to me too since upgrading to Parallels 18. Without conditioning turned on, network is super slow (about 100-300KB/s, with conditioning (WiFi option) on it goes full speed as older Parallels used to do). With conditioning on, network works fine for a while and then all connections are interrupted (especially when downloading something). Disabling conditioning sometimes recovers (back to super slow speed), and enabling it again sometimes goes back to full speed for a while. Often, the network option in the menu bar ignores changes from it, and I have to go to the VM settings and switch off conditioning and on again from there. This happens in Shared Network, and also in Bridged Network, although in the latter it happens more frequently.
Macbook Pro 2019 2.4 GHz 8-Core Intel Core i9 64GB RAM, VM running Windows 11 with 4 cores and 16GB RAM. Mac is connecting via Wifi to my DSL router.

Hello,
As a possible work-around, kindly follow the below steps:
1. Disable network conditioning temporarily.
2. Follow the steps in this article as a work-around: https://kb.parallels.com/129589
If the issue still persists, kindly collect a fresh report at the moment of reproduction and send the report's 9-digit ID in reply to this post.
Thanks

THIS!

Activating Network Conditioning stopped my network from failing every 10-20 minutes. Thank you very much for your post!

Shutting down Windows 11 Pro (Version 22H2, OS Build 22621.1635) VM on Parallels Version 18.2.0 (53488), then selection "Hardware" and enabling "Windows Conditioner" and then restarting the VM seems to work.

When I was young, performing an OS Upgrade used to solve problems and make things better. Now, we seem to have MORE problems after an upgrade. Unbelievable.

I can't even get a Win 11 ARM VM to run in bridged mode on a MacBook Air M1. Completely unreliable. I use this for Windows testing but I've had enough. Ditching Parallels once licences expire in favour of a Windows laptop.

Problem still exists and I'm still running 17.1.6. I have tried the most recent upgrade 18.3.1 and the same problem.
I have determined that the problem with the virtual machine dropping internet connectivity is that Parallels tries to change the MAC system time.

The system time has changed to ‎2023‎-‎06‎-‎26T11:54:53.235000000Z from ‎2023‎-‎06‎-‎26T11:41:03.528011400Z.

Change Reason: An application or system component changed the time.
Process: '\Device\HarddiskVolume4\Program Files\Parallels\Parallels Tools\Services\prl_tools.exe' (PID 3912).

RTC time: ‎2023‎-‎06‎-‎26T12:54:53.235000000Z
Current time zone bias: -60
RTC time is in UTC: false
System time was based on RTC time: false
Parallels support has known about this for over a month now but still nothing resolved, just a series of will you try this and that.
For an international significant software company this support is really of the poorest quality.

I had the same issue on all versions of parallels 18.x.x. After 5-10 minutes the lnternet connection was gone before I reboot VM.
Today I decided to explore some settings, and found, that moving off check-box "Suspend windows after 30 seconds inactive" solve my problem.
Perhaps, this will help to you too.

I have upgraded to Parallels 19 and the problem persists. I have done all the thing mentioned in this conversation. No joy. Annoying.

 

[GrahamB4]

I have had this problem for many months as well and Parallels seem unable or unwilling to fix it. All I get is constant "try this and try that"
Still running 17.1.6. For a major software company it's unbelievable that their support is so poor.
Thinking of dumping them and going to an alternate solution.

Hello,

Thank you for your feedback.

Please collect a technical report (right-click Parallels icon in Dock > Help > Send technical data > check "Attach screenshots..." > press Send Report) and provide us with the report's 9-digit ID in reply to this post.

Thanks

I am currently in the trial version of parallels and I am having the same problem. I was thinking of buying the pro version for my macbook air
Has the Parallels team still not found a solution? :/

Hi,
Macbook Pro, 2,6 GHz 6-Core Intel Core i7, osx 13.0.1 (22A400)
Paralles Version 19.0.0 (54570)
Host linux Debian 10.10
Very slow network and shared folders between OSX and Debian. Not usable for work. I try all thinks beffore.
It start on update to Parallels 19 !!!!

Staff Members any solution?

Same problem here. Insanely annoying. Tried all suggested "solutions" I could find in the forums, but nothing worked.
macOS (13.1) and Parallels (18.1.1) on a M1 MacBook Pro.

Since upgrading to 19.0.0, the issue seems to be resolved for me.
I see others saying that 19.0.0 doesn't help them, so I hope networking remains stable for me..

I reverted Parallels to 17.1.6. Internet connectivity for Windows 11 seems to be working again.

Upgrading to 19.0.0 seems to have resolved the issue for me.
I see others saying that 19.0.0 doesn't help them, so I hope that my networking remains stable.

Having the same problem. In my case it is happening very often (every minute or less). So far have submitted a couple technical reports and Parallels looking into it.

Host is macOS 14.4.1 (latest as of now) and the image(s) (all) are latest Windows 11 (Windows Insider and regular), with nary a change but with all Windows patches to date. Laptop is a new MacBook Air M3 (before I thought it might be the hardware).

Issue has been going on like forever, but finally reporting it.
Only worth noting that I'm using 1.1.1.1 for DNS resolution, and saw another message with that same IP, though I doubt it is related to that, worth mentioning.
