I have a Netgear DG834G v3 ADSL router which I have had since early-2007.
When I work from home I connect to office networks on a Windows 7 machine via a Rackspace-provided VPN using Cisco System VPN Client 5. It works well, except for one issue that is costing me time every working day.
I get intermittently disconnected from the VPN, without any warning or apparent reason.
Since I bought the router 5-6 years ago I have had no need to update firmware, so other than ISP configuration I have had no need to change the router at all and I can say it's worked well for me.
What would be the reason for my VPN connection dropping? Is this an ISP issue (my ISP is Carphone Warehouse/TalkTalk) that I have to take up with them or is it more likely a hardware problem with my router or a VPN configuration issue?
My instincts are to not look into VPN config at the moment as I know a colleague who uses the same VPN through a different router and their ISP can stay connected for hours, even overnight.
