Making FiOS Actiontec Router and Apple Bonjour Services Play Together

I have Verizon FiOS at home. It's very fast, but if you want optimal speed and all the features the service offers, you must use the router supplied by Verizon. This week, Verizon replaced my old router with a new one: Actiontec MI424WR-GEN3I. Unlike the older model it replaced, the new router is a Gigabit LAN router and a 802.11n wireless router. That's great! But with the new speed also came a new problem: Bonjour services were't working properly on my home network. Specifically, my MacBook (using WiFi) could not find other computers and printers on the network.

Apparently, this is a common problem.

First, I tried this supposed solution: disable 802.11b mode. No luck.

Then, I saw this suggestion: create an ACL whitelist entry for 224.0.0.251/255.255.255.255 in the IGMP proxy settings on the Actiontec router. That sounded ridiculous, so I kept looking.

Finally, I came across this: disable the IGMP proxy on the Actiontec router. I am loathe to disable a default setting that I don't understand, but this fixed my problem instantly, and I have yet to see any negative consequences.
