Actually, back in February, i replaced an old DOCSIS2.0 Linksys modem with a CiscoDPC3010. And then in about april started noticing these issues. Had a tech come out around June. He checked the signals and they were all good, he replaced the modem any way, with a Cisco DPC3825, but the issues remain. I've noticed a marginal improvement since I called a few weeks ago and someone was supposed to check the neighborhood lines. I don't know if that actually happened or not. But i'll keep monitoring.
