Quick, take a guess, what's the first hop latency to your home wireless router?

Below 1ms, right? Yeah, you wish!

Below are results from a quick test on my home router (Linksys E1550). Some lessons learned:

• 3-8ms median
• very different latency tails on different channels (1,6,11)
• running in mixed mode helps tame the long tails (do it, if you can)
• all tests on 2.4Ghz, unfortunately E1550 can't do 5Ghz
