Speeds through router

I have a fairly basic home network set up. I have a cable modem which is connected to a linksys wireless access point w/ 4 port switch (802.11b) - I'm on a desktop computer with an ethernet connection to the router.

Oh and because my ISP has its own network service, they in effect 'hide' their modems' information, thus, I had to input the physical MAC address of the modem directly into the routers configuration settings. Don't know if that matters, but w/e

My problem is with speed. The actual bandwidth is not that bad, around 2800 kb/s, compared to around 3200 kb/s when compared to being connected to the cable directly. However, pages do take forever to load, if they load at all. Typically if I enter an address in my browser (IE6) after about 5 minutes of seeing "Finding site: URL" in the bar, I'll get a 'page cannot be displayed' error, as if the connection timed out. Then if I refresh the page will load in a split second.

Watching the diag lights on the router, it seems entirely inactive for a few minutes, then all of a sudden the activity starts. Its almost as if the router is taking its time to actually recognize that its being contacted by the computer.

K, so called linksys a few times: They've told me to, update the firmware, update the firmware again, reflash (all failed ventures) and when I called them the last time they said something about enabling the MTU and setting its size to 1492.

That didn't help, and I can't call the aforementioned pricks at ISP to confirm the size. I feel as though this could be helpful. But of course I know nothing, so your advice would be much appreciated.

Thanks much for reading.

You can figure out your MTU whenever you want without calling the ISP. In windows just use ping, set the packet size to test MTU - 28, and set the fragment packet flag. If the ping works as normal, you're at or below MTU. If you get an error, you've exceeded it. Keep doing this until you isolate the highest value you can enter.

Code:
C:\########>ping -f -l 1472 216.92.211.178

My MTU is 1500 (1472 + 28). Just FYI, setting MTU is a standard Linksys tech support task, kinda like checking your cables.
