Sync speeds are reported from modem router, Tp-link Archer D9
Possible cable distance 1916m.
Normally we would be getting:
ADSL2+ DOWN:10.3-11 Mbps, 6.0 dB SNR margin, 33-34 dB attenuation
For more than 3 weeks we are getting:
ADSL2+ DOWN 2-5 Mbps, 6.0 db SNR margin 38-40 dB attenuation
Every night at around 8:15pm-8:20pm the connection will discconect and reconnect at a 1.5-2.5Mbps using all setups, restarting modem does not help.
Tried to do isolation tests with all equipment: 2 modem/routers, 4 cables, 2 wall adaptors
Setup:610 socket-->RJ adapter-->cable0-->filter/splitter--> (cable1-->Phone) and (cable2 --> ModemRouter)
Slow speeds of 2-5 Mbps, random disconnects
Disconnects when home phone rings, is picked up or put down. Noisy line.
Setup: 610 socket--> RJ adapter--> cable1--> Phone
Minimal noise/would not cconsider noisy
Setup: 610 socket --> RJ adapter--> cable3--> ModemRouter
Slow speeds of 2-5 Mbps, still randomly disconnects
Disconnects when the home phone number is ringed.
Telstra outages page said our address had planned maintenance up until 26/01/2020. Since then, the address is said to be no longer under maintenance, i thought the maintenance would be the cause of the problems but its been 4 days and the problems still persist.
Other observations:
- Auto sync up is ADSL2+ and sometimes ADSL2, Changing modem to use ADSL2 lowers attenuation to 35dB, with similar speeds. nightly slow down still occurs with ADSL2.
- Checking TPG DSLAM map there is someone within 100m of my home who also has bad ADSL2+ sync speeds of 2.6Mbps at 4.1db SNR and 40.5 attenuation down. I think they also get the nightly slow down aswell.
The phone line rental is with Telstra, i can't report a fault because under their categories as there is no problem when the phone is solely connected to the socket and they will just say its the modems fault and charge me $120 for nothing.
