Hi,
I recently installed a Dlink DIR655 and, I have been getting latency spikes in online games (League of Legends). My ping is usually 80-100, but the spikes go to 300-500 or disconnect. There about 15 devices (laptops,phones,tablets..) connected to the internet and, some of them stream HD videos.

Here are the generals about my current router:
Firmware Version :1.35NA,  2010/11/12
Wireless Radio :Enabled
802.11 Mode : Mixed 802.11n, 802.11g and 802.11b
Channel Width :20MHz
Channel :11
WISH : Active
Wi-Fi Protected Setup :Enabled/Configured

QoS
Enable Traffic Shaping: yes
Manual Uplink: 2048
Connection Type :Auto
QoS setup: all enabled

WMM enabled: yes
Short GI: yes

Thank you,

[FurryNutz]

You may want to set up some QoS rules for all the other devices and put them at a low priority like 200 and put your gaming device in a rule at a higher priority, say 100 or 50

Thanks for the reply.
I am not experienced in the QoS. I do not know what to enter in many of the QoS fields.
Does dlink have a MAC priority list?

Thanks,

[FurryNutz]

Please review this:
Gaming and QoS for XBL

It's for XBL however substitute for your game the port numbers. Use the PC rule listing for your devices.

Thanks,
The game forum moderators do not suggest the use of QoS. Are there any other alternatives to fix my problem? Also, should I upgrade the firmware and do you know which versions are stable?

[FurryNutz]

I would try the QoS and see if it works. At least put the other devices in a rule and set a low priority. Have the other devices online while you game is probably the cause of the latency and lag. QoS can help with this.
You have the most recent available version for your Rev A router.

The game server connects to ports UDP 5000-5500. Should I set the Protocol to UDP and the local and remote ports to 5000 to 5500?
Also, I don't really understand the last two entries : Single PC and multiple PC. Do I just simply use the IP address from the DHCP reservation list for both endpoints for the other devices?

Thanks,

[FurryNutz]

Use BOTH as the protocol, test with single PC using IP address that you reserve on the ROUTER for this PC. Use this IP address in the From and TO range fields. input the ports you need for the game for this rule.

Create a different rule for the other devices, using the Global rule example, input the range that you reserved on these devices on the router, so if you have say , .100 to .120 for these devices, input 192.168.0.100 in the FROM range and 192.168.0.120 in the TO range field. This in cover all the devices. Use ANY as the protocol. This will automatically set the Remote Item to grayed out however thats find as it's suing global information.

Thanks for the reply.

I did what you told me to, but it seems like there's is still latency lag.
Here are the screenshots of my dlink settings.

Also, I manual pinged the server and, I was getting request time outs

Do you think I need a new dual band router?

[FurryNutz]

Need to narrow down if it's the router or something else causing your lag first off before trying a different router.

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
Double NAT
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

If your on Cable, please ensure the signal going into the ISP modem is good and at spec for the modem. Have the ISP check there lines and any log information. Using t.v. line splitters can effect signal going into the cable modem. Garbage In, Garbage Out. If your on DSL, ensure the phone lines are the same as cable, signal is good and lines are filtered where needed.

I would check in game performance with you PC directly connected to the ISP modem.

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.

Rogers Internet. Cable
What ISP Modem do you have? Stand Alone or built in Built in router.
Cisco DPC3825. Built in router
What ISP Modeml do you have?
Cisco DPC3825

The Modem is in bridge mode. I tried filtered the network to me MAC and, the latency lag disappeared. The wireless and wired network had no latency lag when all devices were disconnected.

Is the WiFi on the cable gateway OFF as well?

It seems that if you turned OFF all other devices accept for the one PC and our not exhibiting any lag that one or any of these devices could be causing a problem here.

I would turn one each device, one at a time, and see which one it could be.

Thanks, I will trying turning one device at a time.

Isn't the Wifi off if the modem is in bridge mode?

[FurryNutz]

It should be however I would try to verify this if you can with Cisco.

[techies]

I have been surfing the web for application that hog bandwidth. I found out that PPStream consumes much of the bandwidth. How can I limit it this or reduce the priority? People on forums say that PPStream automatically changes its ports.

Thanks,
