Cable Modem/Router. I recently upgrade to 7.0Mb x 768Kb on each. I used to have 3.0Mb x 768K on ADSL and 2.0Mb x 384K on Cable. Both have static IP addresses. When I connect either modem directly to a PC the speed is fine. This worked before I upgraded and after. Previously, when I connect the modems to my router through my NM-4E (E2/0 and E2/3) card the speed was fine, I gave up about 15% throughput based upon my configuration. I can live with that. Currently, after the upgrade to 7.0Mb down, my speed is effectively cut in half. Approximately 2.7 to 2.8 down, up is fine at 720Kb. I understand that my configuration is restrictive, so I configured my NM-1FE-TX (F0/0) to be bare bones, least restrictive. When I did this my speed improved to almost exactly half. I have been to Cisco website for hours, Google, here, all to no avail. Any help would be greatly appreciated. Below the configuration are my SH Interface and SH IP Interface outputs.
