Strange, I'm seeing huge latency on my wireless connection even when there's no heavy traffic at anywhere. After some troubleshooting, I found Linux refuses to select any data rate faster than MCS 0 (BPSK) even with a good signal strength, and a speed test runs no faster than 3 Mbps... Rebooting the router doesn't help, and this is not the only machine that has this problem.

Must be radio frequency interference, something must be smashing the 2.4 GHz band right now - time to start making a loop antenna and foxhunting the offender with a spectrum analyzer? Well, I probably should save the trouble and upgrade my wireless connection to CAT-6 Ethernet instead...
