I won't either, just asked that have you tried that to see if that works without packet lost and such? Are all of your clients wireless-n (the acer one is, I know)? The reason I asked you to do this is because my g client does not suffer from this problem, it only suffers a little of cyclic packet latency of a magnitude less than 50ms, not thousands ms or lost packet like wireless-n. I haven't had the chance to do it as I am at work, will do this later tonight anyway. If it's confirmed that this problem is by design or firmware bug(s) I am going to bring this thing to the close by shooting range for relieving stress and then getting a router from some other manufacturer. Going to stay away from D-Link in the foreseeable future at least until D-Link put their act together, simply had enough.

This afternoon I back home to verify the 40M and 20M wireless option, seems 20M mode work much better than 40M, even 20M mode still show some TX/RX packet dropped and error in wireless statistic menu when connect to N client, but the total error ratio is much lower than 40M,

only my acer is N adaptor equiped, others is old G wireless adaptor, N client has ton of error and packet dropped, G client seem normal, but all G and N client will suffer wan reset or wireless disconnected and router ping lag ,

One thing that helped me is that some wireless network cards have a hard time operating in a mixed b/g/n environment.  I had to set my N laptop down to G only since it could not work well in N mode with other G devices also running.  My transfer speeds are not as high, but the pings tx/rx has been rock solid.

after spend 2 weeks on 2 655 router, the conclusion came out

- only 1.21EA firmware can avoid wan reset and ping router time out

so I flash the firmware to 1.21EA, now everything seem ok for me.

I can confirm this issue also.  During heavy upload load (1-4Mbps) my DIR-655 router reboots about every 10 mins.  This happens when uploading using FTP with 1 connection so it has nothing to do with the number of TCP connections but with the upload data rate.
I do have QOS turned on.

Hardware version A3 firmware version 1.33NA  This also happens with firmware version 1.32  I upgraded in the hopes it would fix this problem.  It wasn't so long ago that uploading didn't cause a problem so I'm guessing that leowood is correct that 1.21 doesn't have the problem.

This is horrible, I can't upload files when I needed!  I've noticed that throttling uploads to 512K or so seems to prevent this from happening, but that what is the point of having 4Mbps upload speed?

All I can say:  If you sell 1 million units per year it would cost only 50 cents per unit to hire a $300,000/year rock star programmer to fix these problems.

[CallMeBufo]

Anyone ever find a solution for this?

[jackthesmack]

Edit: This was not the problem. I actually found the real problem here.

I FOUND THE PROBLEM!
I am now seeding 300 torrents and downloading a single one at 1MBPS with global max connections at 1000. Router is DIR-655, Hardware Version: B1, Firmware Version: 2.10NA. The router is running perfectly and so is the internet

The issue is an option in uTorrent called "Enabled bandwidth management" uTP. I disabled that one option when I was getting pings to my router of 40+ms. Then I closed uTorrent, reopened it, and after 10 minutes my router is still pinging at less than 1 ms.



I also have UPnP and NAT-PMP port mapping disabled, which may or may not effect it.



If you want to see live how your router is responding while you make changes, in Windows hit the Windows Key > type "cmd" > Enter > type "ping 192.168.1.1 -t" (or whatever your router's IP is) > Enter

if the pings start consecutively going over 2ms then you are having router issues. Leave it on the entire time you are testing new settings and resetting your router, it's very useful for seeing how stable the device is.

[FurryNutz]

Awesome info. Would be great to get some feed back from others to see if this helps resolve there issues. I've added this information to the Torrent FAQ.

[jackthesmack]

OK now there's a new problem. The router remains stable under load, and I can access the setup page perfectly fine and quickly while using uTorrent, but now the connection will drop sporadically. My family members were complaining about the connection going in and out. My pingings to router would stay at >1ms, but then it would disconnect and reconnect within a few seconds. This occurs infrequently. uTorrent is still the culprit. This is a completely new problem from the other one I fixed earlier. Will have to do more testing.

What region are you located?
Are you wired or wireless connected to the router?
Has a Factory Reset been performed?


What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
Ensure devices are set to auto obtain an IP address.
If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
Turn off WISH, and WPS under Advanced.
WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
Set current Time Zone, Date and Time. Use an NTP Server feature. Tools/Time.
 
Links>Wireless Installation Considerations and Managing Signal Congestion
Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
What wireless modes are you using?
2.4Ghz Routers only: Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Enable WMM Enable Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

[jackthesmack]

I'm located on the West Coast of the USA. I am physically connected to my router. I have factory reset it several times.

I have Cable internet with a static IP. My modem is a Surfboard SB6121

1: QOS and Traffic shaping already off.
2: Advance DNS already off
3: Unicasting already on
4: DNS Relay already on
5: DHCP is already enabled for all devices.
6: All devices except a network printer is set to auto obtain IP, but I have already tried disconnecting it and I still get the problem.
7: IPv6 is already disabled
8: I will now change my UDP/TCP Endpoint Filtering to Endpoint Independent.
9: uPnP is enabled, but multi-cast is disabled because the media server stuff that pops up under networking annoys me and isn't used. However, uPnP is disabled in uTorrent so it shouldn't effect it.
10: WISH already disabled>
11: This spec sheet for the SB621 says the ethernet port is 10/100/1000 MBPS, so I left my setting on 10/100/1000 MBPS Auto.
12: Time and NTP Server settings already on.
13: SSID is changed. I have 2 routers with the same SSID and same password, one is acting as a hub. But disconnecting the other router doesn't help, and it shouldn't matter since I am directly wired to the router when this happens.

Code: [Select]

Wireless Radio :   Enabled
802.11 Mode :   11bgn
Channel Width :   20/40 MHz
Channel :   6
WISH :   Inactive
Wi-Fi Protected Setup :   Disabled
SSID List :
Network Name (SSID) Guest MAC Address Security Mode
You shall not pass! No 84:C9:B2:67:8F:66 AUTO (WPA or WPA2) - PSK
14: Ok there is so much about wireless I just disabled the wireless.
15: All firewalls on my computer are already disabled.
16: Only had my PC plugged in, disconnected everything else. Still lagging terribly
17: I plugged first my computer into the modem directly with the cable that goes from the router to the modem: There is zero issues. Then I plugged the cable that normally goes from my PC to the router: Zero issues. This is while seeding 300+ torrents. I even set my upload limit to unlimited and I am seeding at 1.2 MBPS and websites load fast, I can talk to people fine on teamspeak, and everything is all dandy. This is when I am not using the router, just the modem. Also IPv6 seems to be enabled because when I am pinging google it uses an IPv6 address

Proof:



After I went through all this, I plugged the following together:

Modem ==> Router DIR-655 ==> Desktop PC (physical wired)

I left the wireless disabled, along with all the options the way you told me to set them. I am still getting disconnected even before I reach those loads again like I did  before. The fix I originally posted helped, but it's still not completely fixed. It seems like it's going back to the old way of the lack of responsiveness in the router and the slow pages on the router setup page.

[jackthesmack]

OK, some more tests. I can have the 289 torrents seeding at once. BUT! If my upload goes above 200kb the router starts to become unresponsive. I tested this by starting a SINGLE popular torrent after my non-popular seeding torrents were online with no problems. The faster it goes, the slower it gets.

Right now my router is pinging an average of 300ms while downloading at 1.2mbps, despite allowing only 20 connections per torrent. When I limit to 500K, it drops to 30ms average. 200K is 3ms.

This is with just 20 connections per torrent allowed! Changing the speed from 200K limit to unlimited does not effect the connection count with this single torrent.

Last test: Only seeding this one torrent, not the other 300. Just 1 single torrent, 20 max connections, unlimited upload. At 1.2 MBps I get 100 300ms.

So to reiterate:
20 max connections per torrent allowed for all tests.
289 seeds with no current downloaders: <1ms
289 seeds + 1 uploading at 1.1MB/s: 300ms
289 seeds + 1 uploading at 500K/s: 30ms
289 seeds + 1 uploading at 200K/s: 3ms
1 upload at 1.1MB/s: 300ms

The amount of connections doesn't seem to matter, it's the amount of data going through that's bogging the router. Why is this?

[jackthesmack]

Alright, last post. I switched to Deluge. It's now uploading at 1.3MB/s and my router is pinging at <1ms.

Whelp, time to add 400+ total torrents to this thing. Hopefully I can find a program to do it for me.

So the fix for this issue is: Switch from uTorrent to Deluge.

I'm sure there's a setting to make uTorrent work, but unless a D-Link engineer runs the program and uses his testing equipment to find the problem, then it's unlikely we'll find out what it is. It could be something as simple as the delay between new connections.

[FurryNutz]

If Deluge is working better than uTorrent, I presume that there could be an issue in the programming and coding of uTorrent. Have you tested Transmission?

[jackthesmack]

Nope, however I am starting to get issues again with deluge. When I was using uTorrent, a single torrent going at 1.3MB/s would hurt my router and make it unusable. With Deluge it was fine.

But then I turned on 215 torrents, and now it's slowing down again. Even with total connections limited to 25 my router is still doing bad, so it's nothing to do with that. All my network extras are turned off as shown in the image below.



When max upload at 300K/s, the router responds with a >1ms ping. But when I set it to 1000K/s it's at 300ms.

It's really bothering me, I'm glad I switched to Deluge though because it's working much better, but the router is still acting up. I want to be able to seed 250+ torrents at 1+ MB/s with no problems.

Edit: Here's my router responses with Deluge running at 300K/s upload and 215 torrents seeding:



Edit2: Here is 700K/s (some reason now it's refusing to climb above 750K/s) upload and 215 torrents seeding:



80K/s upload and 215 torrents seeding:



In all these pictures I had less than 60 connections. Also when I try going to websites while uploading at 700K, I kept on getting "DNS server unresponsive" errors and no sites would load.
