    Well still we have no fix 6 months later, but hey at least the new version is out.
    Maybe v18 has turned this fix into a "feature" that can be had for the $70 upgrade cost.

    I have Parallels v18 and still have the issue with slow network.

    I solved this issue this time by reseting the network configurations in windows:

    in Windows go to Configurations --> Network and internet --> Advanced network configurations --> Restore network configurations

    I hope this is helpful, this problem is really annoying.

    I have found the issue for me was that I kept the Optimization setting one click under "No Limit". I have run like this for years. After an update to Parallels I started having the network issues. Resetting the network card only worked for a while. I change this setting to "No Limit" and have not had the issue since. Btw, this was happening on both my work Mac (M1 Pro Max, Win11 ARM) and my personal Mac (2018, i7, Win 11 x64).
