MacLeech Comcast supports it.
When you select any of the symmetrical tiers on Comcast in a 4.0 area, you still have the option to bring your own modem, you just get the slower upload speeds. Download speed is the same.
Same thing is possible on Charter.
Either way, I reported it to the FCC, since it’s clearly a violation.
If Comcast can do it, so can Charter.
The FCC doesn’t differentiate between new customers and existing customers. If new customers can’t bring their own modem, that’s a violation.
They were already investigated and fined for this before.
