f‑GNP were prepared by silanization: 5 g GNP were dispersed in 200 mL ethanol, sonicated for 30 min, then 0.5 mL APTES was added under nitrogen. The mixture was refluxed at 80 °C for 6 h, filtered, washed with ethanol, and dried under vacuum at 60 °C for 12 h. FTIR confirmed the presence of Si–O–C and –NH₂ groups.
Current PPPoE implementations may hang during "Initial" or "Connecting" states if the peer does not respond within a specific window, requiring a manual interface restart. Administrators lack visibility into why a connection dropped (e.g., PADT received vs. timeout). 3. Functional Requirements Auto-Restart Logic: PPPE-097
