Home Network :: Optimization For Packet Loss / Desync Reduction

Jun 27, 2011

I have recently been testing out the Kaillera netplay application thats embedded into a few old console emulators. Now the major problem is the de-sync between clients and I was wondering which is the best to reduce this.Say I have an upload speed of 1.2 Mbps and a download speed of 11.28 Mbps. Obviously, I am capped by my upload speed when it comes to changing how many packets i can send/receive per second because its all one setting and I am usually playing P2P.So, I am not entirely sure how big the packets are that are being sent, I am guesstimating based on what they said on Kaillera website that it is around 200-300 bits.Anyway, with my current upload speed I can transfer at a rate of like 600-800 packets per second depending on packet length.De-sync's happen quite often especially in the higher rom size games like Mario Party because of all the data being transferred. Would it be wiser to increase my setting of pps from 20 packets/sec to 60 packets/sec?

Regular Packet Loss On Wireless Network?

Apr 6, 2012

I am connecting to a Wireless network, through a ZyXel ZyAIR G-4100v2 router. My problem is that I am experiencing very regular packet loss every minute or so. This lasts for around 5-10 seconds on average. I am running XP with the latest service pack. So far, I have checked out;Wireless Zero Config scanning of new stations (disabled that feature).Xirrus network scan (signal is fine and consistent). I am not suffering from any degredation in signal, the problem seems to be that the router is simply not allowing anything through at regular intervals.

Linksys Wireless Router :: WRVS4400N - Laptop Gets Battery Power / Network Getting Packet Loss

Jul 24, 2011

So I have an WRVS4400N V2 and just got a new laptop with an Intel 6230 Wifi card in it and have an odd problem.While the laptop is on battery power the network gets massive packet loss.

I don't know what to do.Laptop manufacture says its AP but AP worked fine with old laptop and works fine when laptop is on power and all other devices seem to be fine with the exception of my Xbox 360 that wont connect if I have it on WPA2 but I will post another thread for that.

TCP First Packet Loss?

Dec 12, 2012

i am implementing tcp as per rfc 793, i have one doubt, while sending first packet, if that packet lost means, tcp will wait for RTO and retransmit the first packet, and after got the ack for first packet, then only it will send second packet or without getting the ack for the first packet it will send second packet.

For about the past 2 or 3 months, I have been experiencing outbound packet loss at about the same time every evening. That timeframe is about 7 PM - 10 PM. This is most noticeable on Teamspeak 3 because of the voice disruption that other users report to me.

Random Packet Loss 100%?

Feb 19, 2013

I have recently switch internet to Time Warner. Since the day I got it, i have experienced random packet losses of 100%. I have called time warner and they are going to send a tech out. But i would like to know more about this before he comes. I have replaced the modem with a brand new one. Surfboard SB5101N from the one i was leasing from them. They both do the same thing. I have made sure all my Drivers are up to date. I have replaced the coax cable and Ethernet cable and ran my Anti Virus and Spyware program. It does it more during online game, I have reinstalled the game and was having no problems with the ATT Dsl i had before this.

Cisco :: Packet Loss Only Across The VPN?

Apr 18, 2012

My 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?

Packet Loss During Same Time Every Day

Dec 13, 2012

I'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.

60-90% Packet Loss On Windows 7 Desktop?

Apr 5, 2012

I have a Windows 7 desktop (so it's NOT wireless) that is having problems with packet loss. Now, the modem is fine, I've tested 'pingtest' on some laptops and the packet loss is very minimal. I've tried reinstalling the drivers for the LAN controller, using a different ethernet cable, using the 'winsock' reset command, and I have no luck. This does effect upload times on YouTube, to where a minute long video takes an hour.

Packet Loss / Internet Lag With Data

Dec 15, 2011

I started using Windows 7, on two different computers. I get pretty bad lag spikes while using Skype and playing online games. They occur about once per minute and last maybe one second. There is a "Network Throttling" fix floating around the internet which I have tried, to no avail. I don't know much more about computers than a basic understanding, and am completely new to Win7.

Packet Loss On Shooting Games But Not WoW

Jan 25, 2013

But I have finally diagnosed the problem. When I try to play games like Combat Arms, Arma II /OA, BF3 and run a ping test on pingtest.net my ping is steady, and my jitter is fine but the packet loss is ridiculous! I will have a packet loss of 90-100% causing the game to be unplayable. But when I run this test playing WoW I have 0% packet loss, steady ping, and good jitter. 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.

Cisco :: Packet Loss Due To Ping Priority

Feb 12, 2013

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."

Major Packet Loss When Particular Computer Is Connected

Nov 28, 2012

I've been having an unusual networking issue lately, where everything runs smoothly apart from when one user's laptop is connected to the WLAN. All users on the network get something between 20% and 60% packet loss, only when this user's laptop is connected. I've made sure all the TCP/IP settings are reset to default, I've reset the router to factory settings, but the problem persists. This only came on recently, and I don't believe anything changed.

High Ping And Packet Loss In Game?

Nov 3, 2012

I 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.

Broadband :: How To Fix Packet Loss On VOIP Programs

Jan 24, 2011

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. Problem exits with or without Port Forward.*running Windows 7 {64 bit}, AMD Phenom 8450 Triple Core, 2.11ghz [3gb RAM] Asus M3A78 Pro Motherboard

WRT54G2 Router - Packet Loss During Gaming?

Jul 1, 2011

I get 10Mbps download, and 1Mbps upload. I play on wire, not wireless!I have a WRT54G2 router, and I've had it working for around 2 years now. I've been gaming(Unreal Tournament 2004) with it and now-a-days I've been getting packet loss and it is super annoying. I keep getting owned during game play because I skip here and there and it lags sometimes. Also, the laptop upstairs that the family uses sometimes can't connect to the router, so I have to unplug then replug the router for the laptop to connect to the router. Is my router giving up? Its a G router, should I shift over to N anyways?

2960S Packet Loss On File Replication?

Oct 26, 2011

I have 2 Exchange 2010 servers and when I enable the DAG and start replication I see both servers NIC cards reach 100% utilization periodically. I normally don't see this on any of my servers but I figure what the heck it'll be really fast in completion. However, when it peaks at 99-100% for short bursts I see packet loss from other systems on the network.

A minute or two into it I start getting alerts of packet drops on the switch these are connected to (catalyst 2960S). It's not across the board but it's enough to wreak other havoc with processes running. I'm curious as to whether this is the 2 servers having a problem or is this switch not up to it?

I believe the last snapshot I took showed most of the active ports on the switch having a 40-50% transmit status when those 2 servers peaked, which didn't make any sense to me. Is there something on the switch triggering other ports to lose packets or is it broadcasting something it shouldn't?

In more detail:-I'm seeing immediate/more packet loss on the network from the 8 or so APC PDU's that are connected to the same switch at 100/half or 100/full (haven't looked into why that is yet some are coming up at half.

-Couple of sql servers were failing over because they could not reach network resources, timeouts exceeding a few seconds. Really just bizarre for just replication files.

Lastly - any way to throttle the throughput on the Exchange replication via powershell or anything?

High Ping And Packet Loss During Online Games?

Jan 24, 2013

about 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

[code]...

OS: Windows 7 Home Premium 64-Bit
System Manufacturer: Acer
System Model" Aspire M5802
Processor: Intel Core 2 Quad CPU
RAM: 8GB
Graphics Card: AMD Radeon HD 7800 Series (7850 to be exact)
