RobMtl007 - check out bug #1636 and apply the change detailed in comment #2, specifically the gconftool-2 command.

If it works for you, please add a comment in the bug with details of your router (make, model, firmware) and the lowest timeout setting that worked for you. Also give an update here so we know how you got on!

If bug #1636 doesn't also solve your HTTPS problem, be aware that SSL v2 is - for very good reasons - disabled by default in Opera as SSL v2 offers weak and exploitable encryption (ie. it's no longer considered safe to use). However some old or misconfigured websites may still be using SSL v2, in which case you have two options:

1) Stop visiting these insecure web sites - perhaps try contacting the admins and alert them that they are putting their users data at risk

or

2) Enable SSL v2 encryption in the Opera "Settings" dialog and tacitly accept the security risk of low grade exploitable encryption
