I've been using my router for about a year now and have been getting sporadic cases of packetloss. I usually notice it playing games or while I'm using a VOIP client. Usually I get high ping over my VOIP and about 30% packetloss while pinging Google.

In most cases, I just restart the router and everything works perfectly for a day or two. I have Firmware version 1.11 and I am using a wired connection.

Any solutions to rectify this problem or am I better off buying a new router.

Please provide more information, are you connected wireless or hardwired. What firmware version are you using?

[Crackerjacks]

Sorry, I had originally said "modem" in my opening sentence. My question is referring to the DIR-655 router.

Firmware 1.11
Wired Connection

Not sure what information I need to provide.

Any other computers on the network? You could Isolate if not already done so the voip with a static ip outside the control of DHCP. Turn off DNS relay(Setup/network settings/uncheck DNS Relay), reboot router.

Yes, I have one other wired connection and two laptops, but I doubt it's a congestion problem since my issue(s) occured when only one computer was being used. 

I have not isolated the VOIP with a static ip nor do I know how to do that. However, my packetloss is not just apparent in VOIP. Additionally, I often have high ping in online games, packetloss while pinging websites, and overall internet connection is slow.

What exactly changes once I turn off DNS relay?

DNS Relay
When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN computers can use, even when the router obtains a different DNS server address from the ISP upon re-establishing the WAN connection. You should disable DNS relay if you implement a LAN-side DNS server as a virtual server.

There seems to be an issue with DNS Relay on the 655, search the forum and read some of the issues. Dlink has addressed it but still seems faulty from the posts I've read.

Are your packet losses happening on the wired connections or wireless connections or both?

Dynamic Fragmentation
This option should be enabled when you have a slow Internet uplink. It helps to reduce the impact that large low priority network packets can have on more urgent ones by breaking the large packets into several smaller packets.

Try this disable Dynamic Fragmentation (Advanced/Qos engine setup/ uncheck DF).

You probably won't need to make any configuration changes after disabling DNS relay. All this setting does, is allows you to use your router IP as a DNS address. For example, if DNS relay is on, the devices currently connected to the router will have their DNS resolution addresses set to the router's IP. If this setting is turned off, the DNS servers from your ISP will be given directly to any device connected to the router. This only affects DNS and not your actual IP addresses. Quite a few people report no issues with their routers after disabling DNS relay, so this would be a good first step.

For further troubleshooting, you may want to connect one of your computers directly to your modem... check your ping times in games and through the command prompt to various sites with this setup. There is a very good possibility that you have some type of line issue, or there is an internal ISP issue that is causing your problem. This obviously will rule out any problem with the router.

If the router is indeed the culprit, and you still have these problems after disabling DNS relay, if it's possible you may want to change the wireless settings on the router to support wireless G or N only (not a mixed mode). Let us know how this works out for you.

Like I said, this problem is very sporadic, but for the past two days, my connection started to get sluggish around 2pm. This happens for both wired and wireless connections.

I doubt it is an ISP issue since I have called several times and they have found no problems with my line. Moreover, if I connect my modem directly to my computer, everything is fine.

I will disable DNS later today to see if this is the problem.

You know you could just be on a full node and as traffic get heavy everything slows or a combo of both, things are not always as simple as it seems, but DNS Relay dose seem to be an issue.

[mhouser]

Could be a VOIP issue. Do you have you VOIP device behind or in front of the router?

[ttmcmurry]

There have been cases where another wired computer can cause weird issues.  Have you tried disconnecting all but your one computer and the modem? 

[Crackerjacks]

What I mean by VOIP is something like Ventrilo (not sure if that is considered VOIP). Since I last posted my router was running fine for two days until I had issues. I then turned off DNS Relay and I just had to restart it now after three days.

Not sure what else could be the problem.

[jason1722x]

Do you have dedicated hardware for the VOIP? If so you need to go with MAC filtering and assign the VOIP hardware a static ip or put the hardware infront of the router. It will help with packetloss.

I keep seeing turn OFF DNS relay, but if I do this I cannot go to any web site....So what is the deal???

you don't have your router cinfigured with MAC filtering and you have the 655 and the cable modem both running DHCP which causes problems. Double NAt.
