Great hardware ruined by anti-consumer ISP lockdown.
| User Type | Recommendation | | :--- | :--- | | Grandma / Casual User | ✅ Perfect. Plug and play. Wi-Fi 6 works great. You never need advanced settings. | | Gamer (Console/PC) | ⚠️ Frustrating. You cannot set port forwarding easily. Double NAT breaks party chat. | | Home Lab / Self-Hoster | ❌ Avoid. You cannot run a Pi-hole (can't change DNS). No static routes. No VPN server. | | Small Office | ❌ Avoid. Lack of VLAN support and advanced QoS hurts. | | User with own high-end router (Asus/Ubiquiti) | ❌ Avoid. Fighting Double NAT or ISP lockouts is a nightmare. Demand your ISP give you a pure ONT (optical modem) instead. |
