I wish he would drop the name of the router he's running into these issues on. I have the same exact issue with my laptop (random disconnects for 30 seconds) only on my home router, and I've been considering replacing the router with something of higher quality.
I use an ASUS 750N, which is starting to show its age faster than I expected, but otherwise services the devices in my house just fine. Except for my laptop, which is the only device I actually need to use over wifi on a regular basis.
