We're slowly starting to open our VDI environment to external access and are seeing more and more users come back stating that their VDI session will occasionally pause for up to 10 seconds. It never disconnects, just freezes. I've also experienced this, but, here's the kicker, only accessing externally and only if I'm connecting via wifi. At my home, for example, I had a zero client plugged into my router with my laptop going over wireless. Packet loss is very minimal on the zero client yet it's quite high going through a wireless connection even though I'm right above the access point (it's sitting in my basement). I've never run into internet issues through my wireless connection and the speed is good. Latency is a bit higher, as expected, but nothing through the roof. Attached are some of the PCoIP logs from the VDI session.
Our VDI image is Win7 and has been properly tweaked. We've also included some PCoIP-specific settings like max audio bandwidth, disabled build-to lossless, and min/max quality levels. No USB redirection is allowed externally as well. So I guess my question would be does anyone have any thoughts on how to help prevent such a large transmit packet loss? Are there any additional tweaks to try? Most of our users are wireless from home and my concern is this will become a larger issue as more and more use this from their home connection.
