WNDR3700 V2 - Torrents slowing down entire network

[mazsa]

Hi,

I own a WNDR3700 V2 with Gargoyle firmware. 5 computers are connected via wireless (4 G, 1 N device, wireless running on HT40), none via the LAN ports, 5GHZ disabled. Signals are perfect, ping to the router is below 1ms. However: whenever any of the clints start torrent downloads, the following things happen:

1 client running 2 downloads:
- active connections go up to 700-800 (DHT, uTP disabled in uTorrent, max 25 conn per torrent, 75 globally)
- ping to the router from all clients goes up to 400-500ms, the entire wireless network slows down
- LAN ports stay fast, below 1ms, only wireless is affected
- wireless signals stay perfect

It's not a bandwidth/QOS problem for sure, since the up/down bandwidth doesn't even reach 1/3 of the full potential.

I can't figure out what could be the problem. This router should easily handle this number of connections as far as I know (although it's strange that 1 client with 2 downloads uses 700-800 connections).
I tried using DD-WRT, no problems there, but I prefer Gargoyle.
Any ideas? Thanks!

I have no idea, but what version of Gargoyle are you using?

I use 1.4.2, but I see that there are new versions. I'll try them.

Try v1.5.0. One change I forgot to mention in the official announcement is that I added a setting that should help to better deal with the situation where there are a lot of connections in the CLOSE_WAIT state which should be closed in favor of new connections. Specifically, I set net.ipv4.tcp_tw_reuse=1

However, the docs say this has the potential to cause problems so I only introduced this in the 1.5 branch. Try that, and see if it makes any difference.
