Mrs Weaver accidentally pulled the mains out of my modem this morning, as mentioned in another thread. ( I may have mistakenly said it was the phone line getting pulled out.) Then I lost ~120 kbps downstream, now around ~2.9 Mbps downstream sync rate on line cwcc@a.1 which is a ZyXEL VMG 1312-B10A ADSL2 BT 21CN. And it has remained ‘lost’, despite all my efforts, including trying a target SNR margin reset, I can't get it back.
Assuming this is BT DLM at work, any idea how long before I am forgiven by DLM (21CN) ? Am I correct in my understanding of this, that DLM might sulk and decrease the speed across multiple resyncs because of a power cut?
