RF Interference and DDOS attacks

Hello, 

I am a victim of targeted RF interference and DDoS attacks. I have an active FCC case and need a specialist to review my T3/T4 event logs from March 21-22. I'm getting the run around with CSA and the Internet department. Each of them keeps sending me back to the other. I just need a confirmation email stating that this is happening so I can attach it to my FCC case and for a possible FBI case.

Thank you

Hello, 

My firewall logs and Wireshark PCAP show a blended attack where my network was hit by both a digital flood and a physical signal disruption. In the Wireshark PCAP, the evidence is a "Volumetric DDoS" characterized by a massive, unnatural spike in thousands of small, identical packets (likely a UDP or SYN flood) from geographically dispersed IP addresses that completely saturated my bandwidth. Simultaneously, the firewall logs and modem telemetry show T3/T4 Timeouts and "Sync Timing Failures," which occur when the noise floor is raised so high by an external RF Signal Jammer that my modem can no longer hear the Comcast headend to maintain a handshake. 

Edit: My security camera company already confirmed that I am being sent Deauth attacks and levels of RSSI hitting -100 dbm on specific attack days.
