I have a new Windows 7 64bit laptop, which connects wirelessly to a ASDL router/modem.
With my regular connection, page requests often time out - usually with form submissions.
When I use the same connection to connect to a VPN (using OpenVPN) the requests seem to work fine. These are not requests to sites that are only available via the VPN - just regular websites
I think this is specific to this new laptop (provided and set up by my employer) - other machines work fine.
Thank you - I think that was it. I used a tool from here to find the best MTU - http://qsextreme.com/mtutest/. And then advice here to set it - http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista-or-windows-7/
