Known Observations

Slow Response Time

The TC4400's status page takes approximately 20 seconds to respond. This is a firmware limitation, not a DOCSight issue. The driver accounts for this with extended timeouts.

HTML Table Scraping

The TC4400 has no JSON API. DOCSIS data is embedded in HTML tables on the /cmconnectionstatus.html page. The driver uses BeautifulSoup to parse these tables.

Different firmware versions may use slightly different column names. The driver uses fuzzy matching to handle these variations.

Frequency Units

The modem may report frequencies in Hz, kHz, or MHz depending on firmware version. The driver normalizes all values to MHz.

Bridge Mode

Status: Untested, likely compatible. The modem typically keeps its web interface at 192.168.100.1 in bridge mode.
