Packet loss issue for 3 months. Solved for a week, now back again worse than ever.

I didn't think a company as big as Cox could possibly have such a problematic service, and was appalled at how poorly trained their techs are. Half of my laymen friends are more knowledgeable than these techs. The only high point was that the 2 tech visits weren't billed to me, as Cox absorbed it. SOMEONE PLEASE PROVIDE A  REAL, VIABLE SOLUTION!!!!
