Hi Martin,
Are your router logs accessible?
Is there anything of potential relevance in those or the pi logs around the time it stopped/restarted 'connecting' (or even in the interim)?
Perhaps
cat /var/log/syslog{.n} | grep -i dhcp
might be a start, where {.n} indicates an optional eg. .1, .2 etc if syslog itself no longer contains logs from the relevant time.
The router may have a web interface that includes a section for errors if you can't get into it with ssh. Not sure how helpful that might be even if one exists, but maybe worth a look.
