All,
I have TimeWannerCable internet.
Recently (well, couple months) my internet connection will lost connection  from seconds to minutes.
It happens day and night at any time, no predictable.
I check with the cable modem, it looks as it should be. 
I use the Balkin N router, All the indicate lights (include the modem light) are blue,
except internet light which turned to yellow and blinking.
yesterday I replaced a brand new Linksys router, it is even worse.
The indicate light for internet connection is blanking and is never able to get the internet connection. 
I have check the IP and it got external IP.
check modem again and it works fine. 
 
Anyone has an idea why? 
 
p.s. The distance between cable modem and router is about 50 feet. doest it matter?
   
Thanks.

Four steps to test and come up with material to give to Time Warner...
1. Do a trace route to learn what the router path is. Do it to yahoo.com so you can see the first half dozen routers.
2. Pick a router about 4 to six deep and note its IP address.  Give the router some name and put it into your /etc/hosts table (easier to remember).
3.  Run mtr to the specified router for a couple of days.  This is a continuous running trace route that gives much better statistics.  
4. Send a copy of the data (do a snapshot of the page) to Time Warner if you have a high loss.  Tell them you have the proof that the network is not performing correctly.
