Poor in-home streaming with Linksys

Hi all,
I use Steam Link to stream games from my gaming desktop to an iPad Pro. Since the switch from BT’s free Smart Hub 2 to the Linksys Velop the stream quality and stability has dropped sharply.

Now the previous router we were using was not exactly known for high performance and the Linksys is meant to be reasonably decent, so I’m wondering are there any settings I should be aware of which could be causing this drop?
