# Executive Overview

## USP Firmware Status

### What We Tested

We ran a full evening review of the current M62 firmware using our Oktopus-based USP lab. That included:

- normal read-only status and discovery checks
- targeted nightly write tests
- direct router verification over SSH
- a one-time non-reset capability exercise to see how far USP configuration control can be pushed

### Overall Status

This firmware is in a usable position for visibility and targeted testing, but it is not yet stable enough for broad automated reconfiguration through USP.

In plain terms:

- the platform is good at reading device state
- it supports some focused change actions
- it becomes unreliable when many configuration changes are attempted in sequence

Current observed write-stability envelope:

- `1` targeted write is usually workable
- around `5-6` sequential mutations already show instability
- by `9+` sequential mutations, timeout and service-unavailable behavior becomes common

This is an observed range from tonight's testing, not yet a formal capacity limit.

### What Looks Good

- Device discovery and parameter collection are working.
- Basic health and runtime visibility are working.
- Router-side validation gives us strong evidence when we need to confirm real behavior.
- Guest Wi-Fi toggle and rollback worked successfully in the nightly test.
- The device remained recoverable throughout the exercise without needing a factory reset.

### What Looks Acceptable But Limited

- Some individual Wi-Fi changes can be applied through USP.
- The new UI action model is useful for targeted troubleshooting and lab use.
- The firmware can support focused support-style actions if they are used carefully and one at a time.

### What Still Needs Work

- Repeated USP write activity becomes unstable quickly.
- Rollback after multiple changes cannot yet be trusted.
- Controller-side Wi-Fi client and topology views can fall behind router reality.
- Radio control remains one of the weaker paths.
- Speed-test related operational validation is still incomplete.

### Risk Position

For engineering and lab use, this firmware is workable now.

For broader operational use, the main caution is this:

USP should be treated as a reliable read and targeted-action interface, not yet as a high-volume configuration engine.

### Bottom Line

This firmware is moving in the right direction and is strong enough to support ongoing QA, demonstrations, and controlled troubleshooting workflows.

The next engineering focus should be:

1. improve repeated write stability
2. improve rollback reliability
3. improve controller alignment with actual router Wi-Fi state

### Recommendation

Share this firmware status as:

- good progress on visibility and targeted controls
- acceptable for continued lab validation
- not yet ready for aggressive automated change campaigns
