WNDR 3700 - low/fluctuating torrent performance?

[randfee]

I bought the router two weeks ago and was thrilled by its performance but yesterday, when I tried to download some Linux ISOs and the performance just fluctuates insanely. I know, you guys will claim its the torrent and the seeders but NO, I've tried all kinds of torrents with thousands of seeders, the behavior of the download performance remains the same. I know what I'm talking about and I cross-tested using my old WRT54G and guess what, I got me an almost constant 2MB/s download speed waiting just five minutes on the linux ISOs using the same vuze-settings.
I guess it must have something to do the loads of connections via torrent, any other download maxes out my connection at 6MB/s.

anyone, any idea?!?

I must ask.. have you set up port forwarding on the BitTorrent ports?

When it starts to download in kb/s are the numbers moving quick or are they moving slow? Then there is some bottleneck. Does Vuze show the NAT green, yellow, red? What are the errors in Vuze?

On the OS, Vuze and Router enable UPnP even though you're forwarding ports. Vuze can use part of your system memory as a buffer for download cache? Are you using the default settings. I know SNB reports this router to be limited to 4,096 for max connections the same limit on DD-WRT routers unless it has number larger than 4KB limit.

What are you getting now in mb/s since prior you were getting 2mb/s. Also are you using Peer Block along with Vuze?

TCP/UDP Port forwarding is on in both cases (old Router and this one), connections are optimal (green smiley in Vuze) and I'm using default cache settins. Max connections is at 400 globally and 200 per torrent.

@tipstir
what do you mean by "are the numbers moving fast or slow"? The download performance reaches a quick maximum (lower then when using old WRT54G) then falls back down, goes up again, back down and so on... just open the provided link for download traffic history. I never seem to get max. speed for torrents, not even close to the values of the older router when using the same torrent files and vuze-settings!

No idea, anyone?

Read this comes off netgear forum about this router lock up with high numbers of concurrent connections typical of P2P type applications,
http://forum1.netgear.com/showthread.php?t=48344

On Belkin N+ and ESR-9850 both the downloads goes smoothly, ESR-9850 it goes faster in the count for downloading. WNDR3700 I don't think NetGear had P2P in the scope for their Routers.

Can dd-wrt increase maximum simultaneous connections for the WNDR3700 ? If so wouldn't that solve the torrent problem :/ ??

I am looking at the FCC ID photo for WNDR3700 and comparing it to the TEW-673GRU FCC ID PCB layout both use the same chip-sets but on the TEW-673GRU doesn't seem limited in MSC over P2P. The Realtek Gig Controller Chip 832KB packet memory buffers is really quick, unless Netgear has puts some limits on the firmware as Trendnet doesn't seem to have such limits.

I'm very interested to know if anyone had changed the default 4096 connections in DD-WRT for the WNDR3700 using the method mentioned here

But it spells it out you can based on the RAM so this one has 64MB. You need to post this question on DD-WRT and see what results you get? Then decided what to do?
