Slow internet speed after installing graphics card

[malicht]

Hey guys!

I installed this recently:

And I have noticed a sharp increase in my lag when i play games such as WOW.

However if I hard wire my pc to the router. The MS in games such as wow remains really stable.

Can installing a new Graphics card interfere with my wireless card?

Something I noticed is that the drivers for the card now have the ability to turn my wireless connection on and off. Which is new to me!

Anyway I just want to get some ideas together.

Edit:

This is my speedtest result whilst downloading from steam and on wow.

It could be caused by the graphics card. Are they close together?

I had a similar issue a while back that caused my connection to drop on a regular basis. I moved the wi-fi card to another slot and my connectivity prpoblems were gone

I've just tried re seating the wireless card and it seems to be better. Gonna just spam wow stuff for a while and see if it is stable.
