On Oct 8th, by ADSL stopped working. Looked at the router info and it said 'Link down': not something I've seen before. There was no information at all showing for the usual stats.
Normally, the 'disconnect' button has changed to 'connect' if it's gone down for some reason.
Then I saw that in the log, it wasn't trying to reconnect at all. Info stopped after it reported the loss of connection.
It was a fine, sunny day.
After an hour, I called my ISP and they could find no reason for it, nor were there any BT faults reported. I was told to call back if it wasn't back up in 2 hours.
It came back up almost two hours later.
Today, the very same thing happened at 3.30pm - 'link down' and the log showing no attempts to reconnect.
It came back up at 5.30.
Again, at the time it was a fine sunny day. (Changed at 7pm though)
I've had higher down noise margins since some thundery weather at the end of August caused it to disconnect briefly, and despite those two 'link down' episodes this month, it's still high today: 9.3down 6.0up
This is how it looks now (we have a thunderstorm just moving away):
Operational Mode ADSL2+
SNR Margin(Upstream) 6.1
SNR Margin(Downstream) 6.1
Line Attenuation(Upstream) 27.0
Line Attenuation(Downstream) 46.5
