TCP Optimizer does't save optimal setting

Post by taffy »

Hi, TCP Optimizer Optimal profile suggests Checksum Offloading should be enabled, but when I apply the change and restart, the software reports that Checksum Offloading is still disabled. How come the setting doesn't stick?

Using a pci-e Intel(R) Gigabit CT Desktop Adapter.

Great software btw, thanks!

If you edit the setting in the Network Adapter properties without using the Optimizer, does it survive reboots?

Thanks for the quick reply. Checked the Network Adapter properties and all Checksum Offloading settings are enabled.

Guess it's just a weird GUI bug perhaps? Anyway all good!

When starting the TCP Optimizer tries to read all properties from the Windows Registry, etc., however, it may not be able to read all adapter-specific settings for all network adapters.. Probably that's the case, it just doesn't read all settings on startup, even though it applies them properly.

Thanks for following up on this.
