What's New
Upstream Bandwidth Display (#81)
- New Bitrate column in upstream channel table showing per-channel theoretical throughput (e.g. "30.72 Mbit/s" for 64-QAM)
- New Upstream Capacity metric in the summary card showing aggregate capacity (e.g. "122.9 Mbit/s" for 4x 64-QAM)
- Bitrate cells are color-coded to match modulation health (amber/red when degraded)
- Makes modulation degradation immediately quantifiable for ISP complaints
OFDM/OFDMA Threshold Support
- Added dedicated 4096QAM thresholds for downstream power and SNR (extrapolated from CableLabs DOCSIS 3.1 PHY spec)
- OFDM and OFDMA modulation strings now correctly resolve to 4096QAM thresholds instead of silently falling back to 256QAM
- Previously, OFDM channels were assessed with a 33 dB SNR threshold instead of the correct 45 dB
Fritz!Box Upstream Power Fix
- Moved the Fritz!Box DOCSIS 3.1 upstream -6 dB display bug compensation from global thresholds into the FritzBox driver
- Previously, the offset was applied to ALL modems, causing false "power warning" alerts on CM3500, TC4400, Vodafone Station, and Ultra Hub 7
- Fixed
tolerated_minfrom 41.1 to 40.1 dBmV per VFKD source - All thresholds verified against VFKD guidelines
Wiki Updates
- Expanded DOCSIS Glossary with SC-QAM, OFDM, OFDMA, and Mixed Mode entries
- Reference Values updated with 4096QAM columns and SC-QAM vs OFDM explanations
