Why does hdmi connection slow wireless internet connection

[mr P]

Why does my internet wireless speed slow to a crawl whenever I plug in an HDMI connection?

HDMI requires a lot of bandwidth to ensure quality on broadcast is not effected.

I personally do not think wireless is ready for sending hdmi streams.

Does it matter whether streaming HD or non-HD over HDMI cable? The network speed issue is occurring with non-HD video.
