Do you force 10Mb on your NIC, or do you auto-negotiate that? Perhaps before you pay a higher fee, your colo centre could allow you to connect to a 100Mb port (with perhaps some traffic policing) so you, as a client, could quickly verify if you want to scale up to their next tier without having to spend these up-front costs on troubleshooting this back-asswards. > I can upgrade the connection to 100mbps for a small monthly fee.

Start with the collocation provider. They should, for free, allow you to have a testing period with their next service tier. Hopefully, they can do it without having to swap your Ethernet cable into another device. If it works during the test, then a small 'migration' and monthly upgrade fee would be acceptable (if they choose). Steve
