This last friday our internet started going in and out and then sometime friday night it went completely out. I have been working with earthlink and MCI the last 5 days now and they are now sending me a new router. I was wondering if anybody else might have any ideas on what might have happend. The following everything that has been tried.

Yes i unplugged the router for a couple minutes.

Earthlink manages our router so i called them and they were not able to get in. They called MCI and they tested the circuit (Line) and they said it was clean all the way up to the CSU (Which is intergrated inside the router). They could see activity going on inside the router (The router was hooked up to the switch)

I unplugged the router from the Switch and hooked up my laptop to the router (Earthlink recommended me to do that just incase it was some virus overloading the network) Still didnt work after i took the router off the network.

Earthlink told me how to get into the router and they had me check all the settings. All the settings were ok. Then they had me completey reset the router to factory settings.

I reset the router up exactly like they told me and still didnt work.

I even took the router into where the smart jack was and plugged it strait into there but still didnt work.

Is there anything else i could try? Do you think its the router? I will find out tommorow for sure because they are sending me another one overnight.

Very likely it is the built in CSU/DSU in the router.... I have seen situations were the they go bad and still report good for line testing.  When MCI tested the line you may want to make a hard loop back plug and use that in the future, I have found that a software based loopback is not always the most reliable test in the world.  Not to mention you can put that same plug into the CSU/DSU in the router and look for interface errors if you are getting them .... well then you know it is hardware for sure.

Thanks

ok take a cable end and 2 realativly short cables run one cable in pin 1 and the other in pin 2 then cross the pin one into pin 4 and pin 2 into pin 5

Here is a link but just do it on a plug end

Basically what the telco was doing ... can you still get into the router?  if you can plug it into the CSU/DSU and then run traffic into it.  Look at the serial interface for errors.  A ping to an outside address should work to generate traffic.

Yes i can still get into it no problem. It should show up in the Statics and Logs area then under Wan Event History. When the MCI guy was testing the line i saw what he was doing from in there. I am going to try and make that loop back plug now.

then generate traffic and if you see error history it means that your hardware is bad.  Then I would Test with MCI with the hard loop back in the SmartJack.

Well i made this cable and but not sure where to plug it in at now. I have tried from port 1 on the router to the computer and got nothing and then i tired from T1 outlet to the Wan port on the router and that didnt work either. Also does it matter which end is going to what?

Thanks

this should be a plug both ends of the wire go into the same plug.... one wire is in pin 1 and pin 4 different ends and pin 2 and pin 5 for the second wire.  Then plug it into the CSU/DSU of the router you will get an UP/UP on the router and then run traffic against the port and if the errors increment then you have bad hardware if they don't then test with MCI.

Thanks

Thanks for all the info on making the Plug....The router was just fine.... It finally got fixed after a week of being down it ended up being MCI. There was a switch turned off. As soon as they turned it back on BAM internet.... Never go with MCI they are worthless..... Or Earthlink at that Matter.......
