We have Virgin Media Business 350Mb at 2 sites and we have trouble when remoting from site 2 to site 1 via VNC whereby the connection often drops. I guess this means there is some kind of issue with either the upload at site 1 or the download at site 2. There are no noticeable issues in normal use otherwise. Ping and throughput are always good.

Both sites have the same service (350Mb dynamic) and setup (Hitron router in modem mode fed into a DrayTek router).

I guess the power levels and SNR is a good place to start. I'm alright with DSL stats but just can't work this out! I would be extremely grateful if someone would be able to glance over this and let me know whether anything looks obviously wrong. Thanks in advance!
