ContributionsMost RecentMost LikesSolutions(Update) Bought a Router/Modem on bad tech suggestion. Should I use new router/modem and replace a Netgear C3700? I bought a TP-Link AC1750 (Archer A7) and a Netgear CM 600 from bad advice from COX tech support(thread here).Chat support suggested my C3700 was at its end of life and needed to be replaced. The problem was my wiring. After getting techs here to address my bad wiring, my signal improved and my WIFI (and signal) is now rock solid. Question: Is there a reason I should keepthe newTP-Link AC1750 (Archer A7) and a Netgear CM 600 to replace my old Netgear C3700? Is the 8x4 a concern? Another concern I have regarding replacing my old equipment is, when I check my logs, I see [DoS attack: Teardrop or derivative] ..... [DoS attack: Ping Of Death] from .... [DoS attack: Illegal Fragments] from .... [DoS attack: Teardrop or derivative] from .... Apparently, this is a common problem [1][2][3][4]. I am unclear if these are false positives or a reason to swap out this modem combo. Only 1 Up Channel Bonded & 51-55 Upstream / Bad Wiring or Buy Modem? Modem: Netgear C3700-100NAS Connection: No spitters in the house. No TV. Modem combo is connected directly to the coax coming from the wall. Coax from wall is closest to the outside connection. Problem: I'm having some ongoing issues with my modem requiring frequent resets. I believe these problems to berelated tomy 51-55 dBmv and my only one locked bonded upstream channel. I believe this is a line problem, and not a modem problem Attempted Solution: Cox tech acknowledged my 51-55dBmv. The tech suggested that i buy a new modem because mine was more than 3 years old. I will post excerpts of this chat log below. Thetech offered to send a rented one to me. However, I discovered he modem came with a $20 self installation fee, so I refused this option. If the modem was the problem, i would rather usethat $20 to buy a NetgearCM600 or an Arrissb6183 and mate it to an Archer C or A7. Question: Does the tech's suggestion to buy a modem sound right to you?
