Well I may have spoken too soon. The 5GHz wifi drops loads, sometimes a couple of times per minute, though the 2.4GHz is OK. If anything I'd expect it to be the other way around!
That's not a major issue though, but the trouble I'm having with VPNs since switching to a SH2 is...
120/12 without a VPN gives an Ubuntu torrent (which is guaranteed to max any line) download speed of 15MB/sec consistently. Brilliant!
120/12 WITH a VPN (either PIA or proxy.sh, so it's not the VPN provider) caps at a hard 4MB/sec. Sometimes it spools up to 15MB/sec as it should but then dwindles down to 4MB/sec as though it's being throttled??
Interestingly if you add a SOCKS5 proxy, you get the full 15MB/sec again even if using the VPN. Initially that suggested a port forwarding issue (not being connectable); whereas using the SOCKS5 proxy - part of my PIA VPN subscription - you bypass that and let the proxy machine handle things. However, this can't be right as I'm set up properly, the port is forwarded on my machine (iptables) as well as on the VPN and the torrent program (qBittorrent) says 'green light - all ports working OK'.
So I'm stumped. What on earth would cause this? The SH1 connected to VPN fine. The fact I get the full 15MB/sec without a VPN, and the full speed again with a SOCKS5 proxy over the VPN (from either company) suggests it's not throttling, shaping or STM. Nor is it the VPN providers else they'd not be able to give full speed when also using the SOCKS5 proxy.
But for two renowned VPN providers, one in the Seychelles and one in the US, to have the same exact 4MB/sec cap? Not a chance. Something's screwy here. It's not my OS as it's worked perfectly until the SH2 swap. I've tried UK, NL, FR and DE servers so it's not the VPN or location (eg routing). I've also tried TCP and UDP over different ports to no avail.
The only alternative is the hub. Surely not?? Anyone got any ideas before I bend the ears of the VPN companies and VM's tier 1 tech support (please God, no...)??
Edit: The firewall on the SH2 is off, and I have a reserved LAN IP over gigabit cat6 Ethernet. I know I had to register the SH2 MAC with VM to get it online but will they have deleted the old SH1 MAC? If not I'm tempted to swap back to see what happens with the VPN speeds.
