-My Cisco 877 worked well but a few months ago started to reboot randomly. The cause of this is undetermined, but possibly PSU related. But the PSU has a cisco propretry connector so I cannot test by substitution.
+My [[cisco-877|Cisco 877]] worked well but a few months ago started to reboot randomly. The cause of this is undetermined, but possibly PSU related. But the PSU has a cisco proprietary connector so I cannot test by substitution.
 Consequently I decided to update to a new model, hence 1841.

 Seems too easy.... and currently untested. Updates to follow.
-Well tested now, the above config worked without issue. After the fibre and NTE was installed and operaational, I connected the ethernet and after I had an L2 link, I disconnected the ADSL RJ45 cable. Whilst this was happening, I was running a ping from an internal machine to 1.1.1.1, after the ADSL was disconnected, this was lost, but 13 pings later it came back up using the fibre.

 So a 13s approx outage, impressive.
