PN initiated a line retrain today as well as interleaving switched on again.
Interestingly the retrain now starts with a 3db snr. Which has tonight now dropped down to zero or thereabouts and the modem is hanging on. Impressive.
Here are the current stats :
/usr/sbin/adslctl: ADSL driver and PHY status
Status: ShowtimeRetrain Reason: 1
Channel: FAST, Upstream rate = 947 Kbps, Downstream rate = 6891 Kbps
Link Power State: L0
Trellis: U:ON /D:ON
Line Status: No Defect
Training Status: Showtime
SNR (dB): 0.3 4.6
Attn(dB): 53.5 33.7
Pwr(dBm): 0.0 12.8
Max(Kbps): 6948 912
Rate (Kbps): 6891 947
I have never synced at 6Mb before as the exchange is about 3 miles away !
Plusnet however are spoiling the speed gain by changing my Current Line Speed during the afternoon from 4.9 down to 4.5. This, when I have not been connected at anywhere near 4.5.
Is there any way to get Plusnet to stop doing this ? Or better still to switch it off altogether.
