Solved by user: Wifi slow when using Miracast

[mb2k]

I'm thinking it would be helpful if Microsoft knew that this issue always occurs with this particular model on Creators Update. Is it not possible for someone from HP to confirm this issue with a similar laptop configuration???

Hi @mb2k,

Thank you for replying,

I understand your concern and would love to help,
However, since this is a rare issue concerning the latest windows 10 creators update, I recommend you either rollback to the last windows before the creator's update using the rollback feature under settings Or  Wait while I research on the same with my R&D team and get back to you in the next couple of working days.

Keep me posted,

If the information I've provided was helpful,

Well, looks like the problem was with a change WCU makes to the "Receive Segment Coalescing State" value.

Prior to updating to WCU "Receive Segment Coalescing State" is set to "disabled"

After updating to WCU "Receive Segment Coalescing State" is set to "enabled"

I ran "netsh int tcp set global rsc=disabled", verified it took with "netsh int tcp show global" and now I get full 150/150 on Miracast when running WCU.

Not sure exactly what this does (or doesn't do when disabled) but I was starting to worry as from what I've been reading, this laptop is actually geared toward taking advantages of the features of WCU.
