Thanks to everyone who has thought about my problem.
Using the good old engineering principle of 'try another one to see if the
problem shifts' I resorted to installing a new Linksys WAG54G ADSL Router.
This was a complete failure with the originally installed firmware.
The best site I found to replace the original firmware was
http://www.linksysinfo.org/
System now runs for 24hours at a time and VPN is reliable enough to use.
Seems Netgear sites and help are better than for Linksys but all I needed
was a solid VPN.
The Netgear ran for 9 months OK and then failed in away which appears
unsoluable.
I did get a lot of helpful suggestions from the Expert-Exchange forum,
($9.95 for a months subscription), but was unable to get the answer - except
for a change box suggestion.
If anyone out there reads this I am sorry it is not more help.
Try a box swap, try upgrading the firmware - but remember to backup/save the
old settings before you load the new ones.
There is a good history of previous firmware versions on FTP sites for
Netgear so if one version does not solve your problem another might, (some
versions are reported as better than others! and all appear to come from
NetGear)
Linksys does not appear to be as well supported - the Linsys site is not up
to much in my opinion. The linksysinfo site, nothing to do with Linksys,
identifies several 3rd party developers for Linksys router firmware.
As I said, backup your firmware and try an alternative after looking into
the comments supplied.
Can't believe how much time I have spent lokking for an answer - hope this
helps you if you are in need.
Bye - John
