Yea, that's a fact that most people miss. Every transmission on the same channel as your wifi network slows you down. Every time two devices on that channel transmit at the same time, they both have to retransmit. They both wait a random time before retransmitting, which is good, but then they do the retransmission at a lower speed too, occupying more channel time, in order to make it more likely that their transmission succeeds. This can mean that every device eventually gives up on high-speed transfers, and starts sending every packet at the lowest possible speed.
