Wireless flakiness

snousleI just updated my directional-wireless Internet service from the $50/month version to the $90/month version. Believe me, it's not quite what you get in DSL land. I was hoping that the upgrade in service would end the Vexing Problem, but it has not.
The Vexing Problem is this. I run PingPlotter all the time so I can see an hour-long chart of network performance. Connectivity is nearly flawless, for hours and hours, until I actually use the connection. If I load several picture-heavy web pages at once, it does not just slow down, but instead stops returning pings entirely. The page-loads all time out. Generally, it's back up in about five minutes. Usually not much less, or much more. Continued use at the pace I usually surf the web will show irregular connectivity on the scale of ~30 seconds.
A typical pingplot looks like this:
Not sure if it's universally true, but rebooting the antenna seems to bring it back faster. (I should test this more to be sure.) It occurs whether I'm going through a router or not. (The antenna contains a sort of "router" of its own.)
Anyone know why this might be? My ISP is basically clueless and unhelpful.

Date: 2010-03-31 01:59 am (UTC)I did this test:
http://help.expedient.net/broadband/mtu_ping_test.shtml
except directed it at www.google.com because that was more reliable.
...and it did indeed show fragmentation at 1482 but not at 1472. I think the default setting for Windows is 1500 so that should be OK...
I guess it wouldn't hurt to fiddle with it?
