Hi everyone,
I posted not too long ago about my modem losing sync randomly throughout the day, and I still haven't been able to resolve the issue. CenturyLink tells me everything is fine on their end and the issue is on my end. I've had my Actiontec C1900 replaced with an Actiontec C2000A and the issue wasn't resolved. This occured after I upgraded to Bonded DSL for 20Mbps service. Both lines accumulate FEC numbers (which I know are corrected packets), but they usually add up in the thousands every 5 seconds. I know having a few really isn't bad; it means the modem is doing its job. But they accumulate 1000s very quickly and sometimes they are CRC errors (500 or so) in the same 5 second window, roughly. After the CRC errors pile up my DSL2 loses sync and it's usually 5-10 minutes before it's back online again. Also, all of these errors appear on the "Near End" column in the stats page. Always 0 errors on the Far End.
My question is could the old phone wire in my home be causing this? It isn't even CAT3; it's a really old solid copper 4 wire cable that's been there for 20 years at least. All of the wires are twisted together and all 4 are being used (I presume to get the 2 lines that are needed for bonded DSL). Could there be crosstalk or anything on this line because of that old cable? I have a CAT6 that I can run in its place, but they wired up the NID box odd and I'm not sure how to re wire this without permanently messing it up. I haven't checked with the modem directly plugged into the NID, yet. My current theory is there is crosstalk happening between the wires (since all 4 are twisted together) and causing the noise and the FEC numbers to accumulate and eventually the CRC errors as well. Can anyone here educate me on this?
