Hi,
since moving to cable broadband from ADSL2 in early June I get constant VPN disconnections. Sometimes it's 59min, sometimes it's 24min, sometimes it's almost 3 hours - completely random. I've saved logs to my desktop but can't attach b/c they're not txt files, but here's part of what one says:

I have contacted my ISP, Telstra, who told me they didn't know what's causing the issue and therefore were unable (or unwilling) to help me fix it. My employer's IT department have contacted the outsourced firewall company, who were also unable to help, so I was told to "get a dongle" for the PC, as a "solution" to the issue.
Setup: Telstra (HFC connection) Technicolor DJA0230 modem, with a Netgear Telstra (HFC) cable adaptor. My Win7 PC has no wireless adaptor, so it utilises 16+ year old in-wall ethernet cabling (at the other end of the house to the modem), plus a Netgear D6300 modem (as a router) plus a Netgear Nighthawk X6 (also as a router - both these Netgear utilised from the prior ADSL setup).
Please bear in mind I'm only an end-user and have a very very limited knowledge of anything IT-related...
Thanks in advance. 
Dee.

Other thing I'd try is running a continuous ping and see if that times out when your VPN drops. Start a command prompt and type "ping -t 8.8.8.8". That will send a continuous ping to one of the Google DNS servers. To stop the ping just kill the command prompt.
Hi there @SteveG :)
Thanks for your response (I know it was a while ago!)
On my old ADSL I never had any issues with Forticlient so I don't believe that's the cause of the constant disconnections, but as stated my ISP say they don't know what the problem is and therefore can't help me.
So I checked the whatismyip.com and it seems to have two different ones.
While VPN is connected:
Your Public IPv4 is: 49.255.132.38Your IPv6 is: Not Detected [/ul][/ul][ul]Your Local IP is: 192.168.4.1Location: Sydney Australia When the VPN disconnects:[/ul] Your Public IPv4 is: 144.132.22.219Your IPv6 is: Not Detected [/ul][/ul][ul]Your Local IP is: 192.168.0.11[/ul] Location: Melbourne, VIC AU[/ul]
Running the continuous PING looked all okay until the Forticlient dropped out, then it gives this message:
"Request timed out.
Request timed out.
Request timed out.
Request timed out.
General failure."
When the Forticlient reconnects (I have to retype the password) it gives the message:
"PING transmit failed. General failure" (five times)
before normal ping resumes.
Problem is, as stated in my OP I don't know what any of that means (other than the connection being interrupted) or what if anything can be done about it. (I did upgrade my Router two weeks ago, but of course that didn't change anything.)
As an end user I certainly don't have any means or authority to switch to IPSec.
Thanks in advance for any further assistance.
