also does internal wiring effect snr and att levels as i have a few 90 degree bends in the cable from the i plate to the extension socket which is only a couple of meters away i'm sure i read somewhere the more bends in the cable the more you lose signal but cant find where i read it
Hopefully someone else will be along soon who is better placed to discuss internal wiring with you, but they may ask a few questions to help them understand how things are currently wired up.
The only type of connections that would be sensitive to tight bends are co-axial cables with air dielectric between the central core and external shielding, for example, or a fibre optic cable. Standard copper cabling, run normally so that it is not crushed at any point, is quite immune to any bends within its length.
The question, touched upon by
Bald_Eagle1, is how your wiring is arranged. Do you have an aerial or underground feed? Is there a separate service cable between the end of the drop cable (if aerial) or underground cable and the
NTE5/A? The
NTE5/A should be fitted with a centralised filter (a
SSFP, service specific faceplate). Normally the modem (either
Huawei or
ECI) would be connected directly to the
SSFP. However a data extension cable can be fitted by the installing technician, if ordered by your CP/ISP. That data extension cable can either be used to carry the Ethernet signal from the modem to the router or can be used to carry the VDSL2 signal from the
SSFP to the modem at a remote location.
So what is your wiring configuration, please?
