⚠️ Tips for Safe Updates
|
Tip |
Why It Matters |
|
Use a wired connection |
Avoids bricking due to Wi-Fi drop during update |
|
Never interrupt power |
Could permanently damage firmware (brick the router) |
|
Only use official firmware |
Third-party firmware (e.g., DD-WRT) voids warranty unless you know what you’re doing |
|
Match hardware version exactly |
Different hardware revs may use different firmware files |
🔁 Alternative: Automatic or Cloud Updates
Some routers (e.g., Cisco Meraki, TP-Link Omada) offer:
-
Cloud-managed firmware updates
-
Scheduled auto-updates
-
Multi-device syncing
These are ideal for businesses or users managing multiple routers.
