It could also be a problem in the wiring in your house (or apartment).

Ok NW, here's something interesting: I am starting to see some additional data errors on my broadband link statistics. Here is the transmit and recieve data information since I booted the modem last night:

Any thoughts? Now I am seeing more issues that does make me think it could be a signal issue - which would be internal wiring, or the aging copper going to the DSLAM.

Still don't understand why some data gets through and others have no chance. Geographic distance makes it harder to route? More complicated sites have problems?

If you are in a house, you should have a NID box. Connect your modem to the NID box for a while, and check the statistics if you can. That will help determine whether the problem is in the house wiring or the telco lines.

If you are in an apartment, that might not be possible.

As for why some sites get through - shorter packets are more likely to get through than longer packets. The larger the packet, the greater the chance that it will be damaged by dsl errors.
