It can cause issues later. Other than that, don't fix.
Hello everyone, first time post here I go! I couldn't run my Ethernet through my attic / crawl space so I used conduit in the living room and in a smaller game room ascetics are not as important so I just stapled it to the ceiling. Long story short, I accidentally stapled my cat5 T_T. Everything seems to work, should I take the staple out or leave it as is?
