No longer have the Intel MacBook Pro but until I stopped using it I had the problem. I had already put in a proper ticket and collected requested information - I hope that helps, otherwise I haven't any more information to give nor reason to follow the issue any longer.

Best of luck.

 

Hi, are there any updates to this case? I've still the same issue. Daily I have to reboot my device twice until the network connection works. Issue since the last update to 18.X. Already tried to change the network settings without success.

txs for the tip.. i confirm bridged mode was working at 2mbps before activating network conditionin. After activating it, it went up to 400 mpbs as it should.

 

Parallels Version 18.1.1 (53328) running on MBP Apple M1 Pro 14". Windows 11 ARM. Network works normal and after several hours disapear until full reboot of Windows.

 

Hi, you should recived the report. 417914694

 

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.

 

Same problem with Parallels 18.2.0 and OSx 12.6.3 on my 16" MacBook Pro. I have tried to change the adapter type to Intel(R) Gigabyte CT (82574L) and activated Network Conditioner with unlimited settings. I still some times have dropouts, but the connection is after a short time reestablished and I can continue to work. In the past I had to reboot my Windows 10 several times every day for getting the network up and run again. It mostly happened when copying big files/folders like 2-3GByte from our server or downloading install files from the internet in the same amount of data, here it almost happened every time.

A strang thing is that we have 2 other employee running Parallels 18, they do not have this problem. But they are running Parallels 18 Desktop, I have Parallels 18 Desktop Pro. Could there be something in the Pro licens that makes the different? It has the Advanced Virtual Networking tools.

 

I am having the same issue. Sent the report. 419275355.

 

I also have the same problem and having been chasing it for days now. Hopefully we'll have a solution soon from Parallels

 

I have done all suggested in https://kb.parallels.com/8978 and more. Even configured fixed ip addresses all to no avail.
I have sent report No 419535420

 

This fixed the problem for 2 days, now I am back with daily disconnected LAN interface and Windows reboot required. Have sent report no 419671750

 

My suggestion to you is to roll back to 17.1.6 and await resolution to the problem in 18.02 that is now being investigated by Parallels

 

Parallels Team! Any update on this? Rolling back is not something that should have to be done at this point considering how long this has been a reported issue.
