A newish flat with this patch panel installed. CAT5E to all rooms.
However theres an issue with DSL sync. With every port except the one its plugged into, labelled a RJ35X port (for home alarms?), it gets 2.5 megabit sync rate. This includes every port around the house and the port below the one its currently plugged into.
On the RJ35X port it gets 5.6 megabit sync rate.
Houses up the street get 11 megabit. But of more interest is the twin flat which is 90% identical to this one and the second half of the building, gets 8.1 megabit sync rate at 36 db and 10 SNR.
This one is
2.5 megabit at 35 db and 12 snr
on the RJ35X its
5.6 megabit at 36.5 db and 12 snr
or when tweaked
7.9 megabit at 36.5 db and 7.8 snr
I'm confused as to why it has to be plugged into the RJ35X port which appears to be for an alarm. Why can the neighbours in a near identical place plug theres into the lounge, so not even in at the patch panel, and get a far higher line speed?
Tried with two modems. Same result.
