qBittorrent and Router Settings Question?.
« on: September 14, 2018, 12:41:35 PM »
The last while I have noticed that my download speeds on qbittorrent appear to be capped at 4.8MiB/s total, previously it was around 20MiB/s. As the latest updates to both AirVPN and qBittorrent happened and were installed around the same time I am unsure which or even if one of them has caused this. Although I have always kept qBittorrent itself up to date I haven't changed the preferred settings since following the instructions in the link from 2014 https://www.techsupportalert.com/optimizing-qbittorrent-speed I watched a couple of qBittorrent set up vids on You Tube this morning and saw that they had the "Use UPnP / NAT - PNP port forwarding from my router " box in the Connection screen checked. While going through mine I noticed that mine was unchecked as the link above recommended that. My IP is Virgin Media and I have their 200GB package and I have a port forwarding rule set in my Virgin superhub3 port forwarding settings for the same port number as I received at AirVPN for qBittorrent. My question is do I need both this Superhub rule set as well as the UPnP box checked in the qBittorrent connection settings or just one of them?. Thanks in advance for any help or advice offered.

  "My IP is Virgin Media and I have their 200GB package"

200GB?! Is that how much bandwidth you're allowed per month?
Speed settings in qBitTorrent (or really any BitTorrent client for that matter) depends greatly on your max sustainable upload speed. (burst speeds may be higher but would cause regular overloads)
You mentioned only your download speeds.

Also, settings when using private trackers are radically different than when using public torrents.
Normally with private trackers, people have 100+ seeding torrents active at once but basically no peers (or only 1 or 2) on any of them. A rare exception may be a superpopular torrent with constant downloaders.
Public torrents often don't "accumulate" seeds on them at least to the extent that private trackers may -- or at least have a lower seed-to-peer ratio. A major exception to this is Linux distro torrents, which is why they are often used for testing torrent download speeds.

  "and I have a port forwarding rule set in my Virgin superhub3 port forwarding settings for the same port number as I received at AirVPN for qBittorrent."

If you are using a VPN or proxy, don't port forward your local modem/router!
You could be getting in-the-clear connections on your real internet IPv4 address instead of through the VPN as a result.

  "My question is do I need both this Superhub rule set as well as the UPnP box checked in the qBittorrent connection settings or just one of them?"

Probably neither, due to the VPN. The AirVPN will have to offer remote port forwarding of their VPN or you will be firewalled in qBitTorrent while using it.
You may sometimes get a green light in qBT (meaning "not firewalled") even when using the AirVPN service if uTP works well enough to do UDP NAT STUN, but that doesn't mean the connection is really unfirewalled.

Thanks for the reply switeck, I should have said the Virgin 200MB package. Using Speedtest without the VPN this gives around 210MB download and 12.5 upload with the VPN the download is around 75MB but funnily enough the upload remains around 12.5MB. I spent a few hours between Google and my PC yesterday trying figuring it out and now I have it all sorted. Port forwarded only from the VPN assigned port, no rules set in the Virgin superhub and a check on the execution log in qBittorrent shows that I am connected only through the VPN in both the correct port number and DNS servers. So all is good now. I always keep my programs up to date with latest versions etc and what started this off was that around 2-3 qB versions ago my downloads on qB were between 14-21MiB/s on a good day and depending on which VPN server I used. Then this dropped to a max of 5.2MiB/s. I am still unsure why this is, if it even is a qB caused effect or if it has something to do with my VPN which recently added IPv6 to their network and are upgrading to what they call Gen2 servers. I am a pensioner and although not completely PC illiterate I didn't grow up with them and as I say it is all working again and to be honest the 5.2 MiB/s speed is still quite fast. Again thanks for your reply.

There seems a bit of confusion in your post over bits vs BYTES.
Virgin probably meant 200 megabits/second, not 200 MegaBYTES/second -- and only for download.
I recall reading they throttle speeds considerably if you use over a certain threshold.

The VPN at 75 megabits/sec DL wouldn't be able to reach 10 MegaBYTES/second in qBitTorrent or other web downloads for that matter, so that's a problem right there!

1. Is qBitTorrent getting incoming peer/seed connections?
1a. Especially ones NOT using uTP?

2. Is qBitTorrent able to sustain >1000 KiloBYTES/second upload speed for at least 1 minute?
3. And did you set the upload speed max in qBT to less or equal to what qBT can sustain?

BiB the 200mb use to be the gamer package and wasn't part of the throttling threshold, also VM has quietly scrapped the throttling.  :)
