Oh for sure, it's one of the main reasons why people believe wifi sucks.

One of my favorite visualizations is Steam Remote Play's debug graph that shows the latency stack up. Playing a game over wifi on a smart phone, it can make subtle stutters significantly easier to track down. In one case, I was able to attribute a periodic latency spike to the Bluetooth radio.

I've been trying to go pretty deep understanding 802.11 the last couple years, between trying to make my home wifi setup work flawlessly, and using it extensively at work for real-time communication between embedded systems.

At home, I have converged on WRT1x00ac devices (with useless DFS). Three as APs, one as the main router, and a couple more to play around with. They can be had for $30 on ebay, have dual core ARM CPUs, and run OpenWRT well. The only reason they work well for me, though, is because I am an embedded engineer and stubborn. Recently I had to desolder failed TVS diodes from a couple of them...
