Wireless adapter making noise/glitches

[henrikas11]

Hello

I was wondering if somebody could help me out. I installed a wireless adapter on my pc and since then when I play a game online or watch something online there will be times when the sound will be weird and noisy for a slight second along with the slowed visual. Also I noticed that it awakes the wireless printer from sleep mode. Could it the wireless adapter be interfering with the wireless printer? I tried to adjust wireless antenna but it didn't do anything. Please help!

Also it seems to quantify when there is more going on the screen (like when the movie gets louder or there is more action in the game)

Poorly shielded audio lines on the motherboard picking up noise from the bus. Only way to eliminate it is to stop using the onboard sound and get a decent sound card.
