My connection seems stable this morning so I thought I’d give some feedback.
For the past 2 weeks my modem has had trouble maintaining sync. Connections have typically lasted only a few minutes. (I’ve had well over 80 different IPs in the last fortnight.)
During this time I’ve noticed:
1. Once the modem has lost sync for more than a minute it will never re-sync unless I do something, like power cycle it. I’ve left it alone for many hours and it has never reconnected.
2. If I power off the modem, and then power it on again within a couple of minutes, it doesn’t re-sync, even if left alone for several hours.
3. If I power off the modem and leave it off for several hours (always at least one hour) before I power it on, it always re-syncs immediately. The connection then stays up for a while, perhaps for 10 minutes, then drops, re-syncs automatically in under a minute, then drops a second time after a much shorter period e.g. 4 minutes.
At this point, after two sessions, it will not re-sync even if left alone for many hours.
4. On two occasions I have powered down the modem whilst a connection was up and working, and then left the modem off for several hours.
On both occasions, after powering on the modem, the first sync session was of a normal length but the second session was very much longer. The first time I tried this the session lasted 5 hours. On the second occasion (now) my session has remained up for 15 hours.
So, looking a lot more stable today and at the moment I feel I can rely on the connection staying up (hope I don’t regret saying that).
Of course during this time my connection speed has steadily dropped, from well over 30Mb/s for the seven months up until a fortnight ago, to its current state of around 9Mb/s (upload 670kb/s). Plus reports my profile speed as 10,000 at the moment. As the speed has dropped my connection times have increased from around 3 minutes to around 20 minutes, but it seems to be the power-cycling whilst in an active session that has had the biggest impact (or maybe that is just a coincidence).
