XB8 stuck on sub-split upstream -- no mid-split, upload capped at 35 Mbps
My XB8 (CGM4981COM) is ranging only on sub‑split upstream channels (10–40 MHz), with no mid‑split and no OFDMA upstream, so my upload is capped at ~35 Mbps despite a 1.2 Gig plan. Please check whether mid‑split is live on my node, and if so push the enhanced‑upload bootfile and re‑provision my upstream. If frontline can't, please open an engineering ticket.

Following up — still seeing sub‑split‑only upstream, no OFDMA; can someone from Xfinity Support take a look?

Hi im having the same problem neighbor has lower speed plan there getting over 100mb upload im stuck at around 40mb upload on Gigabit extra we both have a xb8 gateway? My signals levels are even better to then there's we both have ofdm on both download and upload signals. so must be the configuration boot file ? Reason im not getting mid or high split speed we both are wired direct to street no splitters at all.
What should i do to fix mine can you send a update ?
