Cause: This is usually a browser timeout or a corrupted file. Solution:
- Do not unplug the router for at least 10 minutes. Sometimes it recovers.
- If still frozen, power cycle the router (unplug for 30 seconds, plug back in). You may have a partial brick. Immediately attempt recovery (see below).
Part 8: When to Avoid a Firmware Update
Believe it or not, you should not always update immediately. Here are scenarios to wait:
- Beta releases: If the file name contains "BETA" or "TEST," do not install it on your primary home network.
- Stable setup: If your AC8 has been running perfectly for two years and you do not need new features, do not fix what isn't broken. Read the changelog first. If it only fixes a bug you don't have, skip it.
- Right before travel: Never update right before leaving for vacation. If something goes wrong, no one at home can fix it.
