Hello WChan5,

I hope you're having a wonderful day. Before we close this thread, let me also add that Modifying the MTU size of Intel® Network Adapter is dependent on the connecting equipment configuration. Please contact the equipment provider to confirm if matching the MTU frame size is required.

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.
