My family owns a NYC townhouse, and with that I had Cat6 cables put in on each floor. However, more recently, one of the Cat6 cables has gone “bad,” meaning it only does 100 Mbps. While we are nowhere close to Gigabit speeds, very less multi-Gig (despite me having had symmetric Gigabit in the past), it’s still not something I’m happy about. What do you mean only 100 Mbps?
