DLINK faulty

I am formally requesting a Level 2 escalation regarding a hardware failure in the building's managed network infrastructure. Over the past 6 months, I have observed persistent network instability characterized by severe Packet Reordering and TCP Retransmissions on multiple hardware devices.

Wireshark Analysis Findings:

A packet capture on an idle connection (no active user traffic) consistently shows:

7,508+ TCP Out-of-Order segments: Confirming a sequencing failure at the Data Link Layer (Layer 2).

9,046+ Duplicate ACKs / 1,710 Fast Retransmissions: Indicating severe packet loss and buffer saturation.

178 TLS "Record fragment length" Errors: Evidence that the managed gateway or unit switch is clipping/fragmenting encrypted traffic.

Local Hardware Verification:

Scope: The issue affects multiple computers connected via Ethernet, ruling out device-specific NIC or driver failures.

Unit Switch: The in-unit managed switch is a D-Link DGS-1100-08V2.

Bypass Failure: A direct connection to the wall jack results in a complete loss of internet connectivity, indicating that the building gateway is MAC-locked to the specific D-Link switch. I am unable to bypass this potentially faulty hardware to stabilize my connection.

Request for Action:

Given the data, this is not a standard signal (Layer 1) issue but a hardware logic failure or duplex mismatch within the managed infrastructure.

Please escalate this ticket to the NOC or a Senior Network Engineer to inspect the managed port configuration for my unit.

I request a physical replacement of the in-unit D-Link DGS-1100-08V2 switch and a reset of the MAC binding on the building's distribution layer.
