Linksys router "internet" light blinks like crazy even when I'm not downloading...

My Linksys router "internet" light blinks like crazy even when I'm not downloading anything. I can completely disconnect all computers from it and it still blinks non-stop. This wouldn't be a problem except that computers hooked up to the routers often experience slow data transfer. Plugging them directly into the wall fixes the problem.

I just reset all of the factory defaults except the admin password and I'm still having the problem. Any ideas?

A number of questions arise:

What is the model of the router?
Are you doing anything specific when you start to notice slow internet?
Is the router wireless? <--If it is someone might be conecting to your router via wireless without you knowing!

A blinking light is quite normal on some routers even when there are no pc's attached.  I do tend to notice this more especially when the internet connection is cable, however I have seen it on ADSL broadband.

It could be that your ISP is pinging you for some reason or you are getting pinged by someone continuously, this can happen sometimes when you visit websites.  The website server sometimes then pings you to see if you are still on-line...

Do you know how to access the LOGS on your router, if so what do they report?

The router is wireless, but even when I disable the wireless portion, I still have the problem.

The router is connected to a T1 line. I suppose the problem isn't that the light is blinking, it's that with the router in place my internet is dirt slow, but without it in place the internet is fast.

Logs on the router don't show any unusual incoming hits.

The internet light might blink because because of almost anything but that shouldn't slow you down. Have you tried plugging a PC into the router with a patch cord (not wireless) and seeing how your connection is? Wireless can be very slow depending on signal strength.

I've also had better luck when I configure static DNS server addresses in the router and maybe even the PCs. Some router seem to be really flaky when you ask it to get DNS servers via DHCP and then also serve them to PCs via DHCP.

Is it the wireless activity light on the router, this might be due to it beaconing at a very high rate. Should not slow things down though.

How do you configure static DNS server addresses?

Fatlad:
The light blinking is labeled "internet", if that helps.

What I mean is, the blinking means that the router is seeing traffic from outside, not from your PCs. What do you mean "plugging them into the wall?" What do you connect them to? Can you plug them all in at once? Also, does the problem occur when only one PC is connected to the router? T1 is only 1.5Mbps which isn't a lot for multiple PCs anymore.

I configure the static DNS servers on the router's WAN configuration page. If the PCs are using DHCP, that may help. If you want to do it on the PC also, you do it in the TCP/IP properties of your LAN connection.
