When I ping my video streaming host's IP address (the IP that they gave me where I can view my IP web camera's video stream), I get anywhere from 0% to 8% packet loss at various times of the day. They're claiming that there's no problem, that this is because this is a router and it's dropping ping packets due to "ping priority giving preference to more important network traffic."
View 7 Replies View RelatedI recently moved from an old apartment in Downtown Montreal, to a suburb area, but still close to where I was before (10 km). I am using the same ISP provider, Videotron. The same speed. I was playing games perfectly fine before, but now something is really wrong. Whenever I join a server, my ping skyrockets up to close to 200, sometimes drifting to 130 but never going below... and often rising back up again.Keep in mind that I filter servers by their pings. I only join servers that display a low ping (although often I won't see any, when I refresh.. there they are). I'll see a server with 30 ping, join it, and be at 200. I'm mainly trying to play Chivalry Medieval Warfare.It's entirely unplayable. Not only is it impossible to properly time parries anymore, but I also get a lot of rubberbanding. I've tested the internet here, and the speeds are accurate. 10 mbps down, 1 mbps up. I am connected to a Linksys E1200 router. I've tried everything I can possibly think of.I went into the router setup, disabled the firewall, added myself to a DMZ, tried to forward every port for steam (although it didn't seem to recognize it as a program)... rebooted the modem, my computer, the router, tried a different Ethernet cable.. nothing is working. It's very depressing. Nothing has changed on my own computer in the move.

View 1 Replies View Relatedabout 4 weeks ago we started experiencing Packet Loss and High Pings while playing games. This affects our 2 PC's and our PlayStation 3 (Since we use them for gaming). We have contacted our ISP several times regarding the issue but each representative we have talked to has had different ideas of what the problem is. They replaced the modem twice which did nothing, so I then purchased 2 new Router's (DIR 601 N150 & DIR 835 N750+). Neither of them solved the issue. my ISP also says it isn't the Internet Cable that is causing the issue. My Download Speeds and Upload Speeds are right where they should be but the ping and the packet loss is the problem. I also contacted DLINK (Router Manufacturer) to see if they had and all we did was upgrade the firmware version and change the Wireless channels which also did nothing. I have plugged this PC into the modem with an Ethernet Cord and played games and all the issues were gone which leads me to believe that Modem and the ISP aren't the issue.
Things I've Tried:
-Resetting the Modem
-Testing each Wireless Channel on my Router
-Enabling and Disabling 802.11n and 802.11g on the router
-Changing the QoS settings
-Installing Software such as Gamebooster and Advanced System Care
-Disabling all Antivirus programs and Firewalls on the PC's
-Using a friends Modem instead of the Cogeco one

Can your wireless router do a ping test to 66.161.11.90 [URL] or any other [URL] for that matter?Mine can't, either with my wireless PB G4 running OS X 10.4 or wired Dell running Windows XP. I tried it with a wrt54g v5 & wrt54g v6 both tests got a 'request timed out' with 100% packet loss. v5 had the latest firmware, v6 is still at 1.00.9

View 7 Replies View RelatedMy workplace has a UC-540 attached to a cable modem, attached to the world wide web.
When we make VOIP outbound calls through the standard ISP, there is no auditory packet loss sympton; however, when we make calls to out sister branch through our VPN, we experience auditory packet loss symptoms.
I would think the VPN should only be affecting the encapsulation of the data. To my understanding the VPN packets and non-vpn packets all hit the router at the same time, and transport over the web in the same manner. Why would there be packet loss over only the VPN??
--Regarding QoS, if a standard layer 3 device receives a VOIP packet encapsulated in a VPN, do the QoS bits in the VOIP packet get acknowledged, or are they hidden by the VPN encapsulation?
My ping is 35ms my DLS at 45.6 Mbps and my Upload is 4.51 Mbps. My Problem is that i am losing about 60 to 90 percent of the packets on a pingtest.net.

View 14 Replies View RelatedI'm having an issue with packet loss during the same time every day at 12:20PM. I checked scheduled tasks, ran wireshark, made a static ARP entry, and ran ping tests. The ping tests show packet loss only when pinging 1 DB server to 1 App server. When the packet loss happens everyone on the network connected to the DB gets kicked out of the DB. They are eventually able to reconnect but its annoying that everyday at 12:20pm they get kicked out. Ping tests from the DB to the Firewall stay constant. But when I ping from the App server to the DB it loses connection at 12:20pm and when i'm remoted into the DB server i get kicked out as well. It's like at 12:20pm the DB server stops incoming connections for some reason.

I am completely lost on what to do, other than contact my useless ISP that will not know what to do. I am really frustrated by this and am not sure what the cause of this is or what to do. I have been researching for over a week and have no where else to turn.

I have two routers, Cisco 3825 and 2811 connected via a p2p ethernet link. The two sides of the links have Huawei muxes with 100/ full duplex set on their interface. I am facing almost 40% packet loss but the supplier is unable to identify any issues at their end. We have tried setting different combinations of duplex and speed settings but no improvement. When set to auto/auto the interfaces are negotiating to half duplex and I am sure this is the cause of the packet loss. Also I heard of auto-negotiation on MUX ports but supplier confirmed no such settings but only 100 Full duplex. If the router iterface is negotiating to half duplex so I suppose there is some thing with the negotition problem with MUX and router port ?
On C3825 I have a Gig interface whileas C2811 has fastEthernet. I guess Gig interface should not negotiate ? Is there a way to pin point the exact fault to supplier ? Also is there work around for this?
Internet usage is very slow when initially opening a site from LAN clients. Once established it is OK. If I ping a site from an LAN client by either host name or IP address it takes about 5 seconds, drops the first packet then is fine after that. if I ping it again immediately afterwards it is fine. But if i wait 2 minutes and try again the problem returns. So I would conclude that seeing it is the same whether I use Host name or IP address it is not a DNS issue. Pinging from the router produces no fault at all. [code] I can ping the router internal and external interface or any internal ip or hostname from the LAN with no delay or hesitation so it is not a switch interface or network card problem.Some sort of NAT issue maybe?

View 7 Replies View RelatedWe have a customer running a Asterisk based Phone system, using Snom 320 phones and a ESW-520-24P as their switch.
Recently we have been confronted with an issue where every 35 seconds their is a very obvious drop of audio for both parties of a call. We know it is not the phone system as we have run tests directly over the BT copper lines that have no drops what so ever. Unfrotunately when we introduce the LAN in any way, we get the drops every 35 seconds.
We are running the whole solution on 1 vlan, yes I know probably better to use two, but the Cisco cannot automatically detect the Snom 320 phones to swap it to another VLAN, which complicates using a VLAN setup.
I really need to work out how to stop these packet drops, but I am new to the world of Cisco and dont really know where to look or what to try.

How do I fix packet loss on VOIP? Teamspeak, Skype, MSN Voice all have inbound jittery clipped robotic voice. Teamspeaks shows "total" packet lost, climbing to at least 20% with Speech packet loss 50-65% then I lose connection altogether. All other network programs (Firefox, streaming music, videos, online gaming) work fine.I have ATT DSL, using a Netgear Wireless G Router w/ built in Modem (model DG834G). The network has 1 attached device, my Dell laptop (which is usually powered off).The packet loss problem is identical on my desktop pc and laptop (both using the same network). Problem exists when nothing else is running, only Teamspeak (or another VOIP) I have replaced all wires, cables, filters. Power cycled modem.
