Huge Latency / Ping Spikes At Random Times With No Apparent Cause
Jun 20, 2012
Since about 3 weeks ago my DSL has been getting totally random ping spikes, from under 40 to over 1500MS for minutes to hours on end. Nobody else is using my internet, I've verified this. There is nothing sucking up bandwidth on any connected device or computer, as far as I can tell through troubleshooting to the best of my ability. I tried switching to a Cisco X2000 modem/router combo and it did nothing, still totally random latency. Also, when I called AT&T about this, they didn't even know what ping was. They ran an upload/download speed test (which is still mostly consistent regardless of latency) and told me I was basically making the issue up.

This has been a problem for quite a while now, jumping from Shaw to Telus,I have completely exhausted, and I have no idea what's wrong.I live in a household with another family, and we share internet connections, Telus Fiber Optik, as of now. Me and my brother both have our own computer and are connected via wireless adapter, and the other family has one laptop with wireless connection.
The problem would be that randomly, the internet would slow down considerably, with pings going insanely high, like over 9000ms (not joking).At first,I thought I was just too far away from the router.So I moved to a room directly under the router, and the internet was completely fine for around 1 week, then the random ping spikes started to happen again. Now, I've tried tweaking wireless settings, and checking to make sure its just not my wireless adapter, however my brother's adapter is new, but it has the same problem too, so I doubt its the adapters fault.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

I have reason to be suspicious as to the game's relevance. These spikes are characterized by no packet loss, as measured by pingplotter and winmtr (more specifically, there is packet loss, but I've come to understand that because it does not continue on to subsequent jumps it's not an issue), and latency leaping to between 250 and 600ms across multiple hops, seemingly without pattern or form, for intervals
Here are some summaries of some extended pingplotter sessions. The suspicion that this is not entirely WoW related is recent, so I'm working on seeing if I can get similar results from some other sources.

I administer a wired SOHO network at a business I own, which is nothing more than a XP Pro machine which doubles as a file server. Typically, there are only 3 or 4 work stations in use at any given time, with 3 printers being shared. Backups are done after hours through portable USB. I have a home quality Netgear router behind a cable modem, and unfortunately need to use two 8-port unmanaged switches due to limited cabling between the workstations and the server. Said switches/cabling could prove to be the culprit, except that it used to work nicely.
A few months ago, while browsing the shared folders where the bulk of the approximately 180 Gigs worth of largely graphics files...(browsing from ANY of the terminals)...I began to be aware of random delays of up to 30 seconds or more. It seemed to be a sudden change, but has grown worse over time.
The files in question typically reside under several subdirectories, ie My Network Places/GID/Designs/Stan/Photoshop Files/TeeShirts... and browsing to the actual goodies progresses nicely until the VERY LAST directory, then WHAMMO.....XP flashlight goes back and forth, back and forth, back and forth.....you might wait half a minute before seeing the actual filenames in the window.
Its exasperating, and can randomly happen even if I'm the only person in the building, and the "server" seemingly has nothing else required of it.

I am playing a game, like Battlefield Bad Company 2. Every 5-15 minutes, I get 3 lag spikes. When I get the lag spikes, everyone who is using my internet, also gets it the same time as me. So my computer is not the problem.For example: I am just running, shooting people (online), and then, randomly, people are running on the spot for like 3 seconds, and then they teleport somewhere in front of them. And then it goes back to normal, then it happens again. It will happen 3 times.

I run windows 7 on a Gateway DX4860 desktop and my problem has been occurring for a long time. I casually play games like league of legends and I believe my problem lies within my computer rather than the network itself because my problem is latency spikes where when I start games with 90 ping, it quickly spikes to 300+ ping ~ 5 minutes into the game and then into the thousands making it absolutely unplayable. I have had this problem on 3 different internet providers and the problem still remains; HOWEVER, while hooked directly to my computer with an Ethernet cord, I have ZERO problems. The house I am living at now doesn't allow me to connect directly.

I have Planet modem ade-4400 linked to a Digitus ethernet Dn 5001a that I use to connect my 2nd PC.The problem is that everytime, both PCs are connected I constantly get lag spikes while playing games.Also, seemingly on random occasions, no matter what programs I run in the background my connection gets disabled with a yellow exclamation mark over my network icon. I get a "The default gateway is not available" error once I troubleshoot, and the connection works fine afterwards.
However, recently after I updated the windows I think, I get another error that says "The connection between your access point, router, or cable modem and the Internet is broken" along with the gateway one. Also, recently, I started having lag spikes regardless of the other computer being connected to mine after the error, and once I turn on my pc. Could it be somehow related to Microsoft security essentials? Since I've installed it at about the same time when the lag-after-the-error started happening.
Error seems to happen more often when I watch something on the internet, or when I quickly browse through the web-pages, or when I'm downloading something. I'm using Windows 7, and another thing to note is that the other computer DOES NOT receive these kinds of errors, and I do believe it does not lag while playing games.The lag after the error and after I start up my pc goes away after some time.

Product: Linksys Wireless-G Broadband Router WRT54G
Version: 6
Firmware: Has Been Updated
I am directly connected to my router. Lately, I have been receiving high latency spikes and total loss of internet. The problem must be related to my router, because when I connect to the internet through my modem I don't have this problem.

I have a linksys router and a AE1000 adapter. When I first plugged in the adapter I had internet problems, always had to reconnect it. Then suddenly it worked flawlessly online and in video games. Now youtube videos load slower and I will get random lag spikes in game that last 5-7 seconds. I have done nothing to change the adapter, it just does this out of random.

Since last night 10/26/12 I have been experiencing random lag spikes on all games (Hawken Beta(installed yesterstay), Mechwarrior beta, MW3, and BF3).
* Framerates do NOT drop when the lag occurs
* Lag last for 1-3 seconds
* Lag occurs on both wireless and wired connections
* Lag occurs when no one but myself is on the network and while others are on it as well
* Only occurs while gaming as far as I can tell
* Unsure if other computers on network are lagging because none of them are gaming computers
* I have performed tests using SpeedTest and the ping/DL/UL speeds are normal
* Tried turning off Anti-virus (Kaspersky). No Change
* Ran virus and malware scans using Kaspersky and malwarebytes. Both negative results
I am able to run to see if it is a laptop hardware problem or a router/modem issue/ISP issue?Cable ISPCisco Modem (with phone)Netgear gigabit routerM14x-R1Intel I5-2430M8GB RAMGeforce 555m 3GBKiller Wireless-N 1103

The router is being good so far. I have a Belkin Wireless G Plus MIMO router with windows XP operating system. This has been going on for a couple of weeks now and I really want it to stop because it is stopping me from doing things that require the internet.

I have fiber optic Internet with static ip and keeps disconnecting at very random times. It started 3 weeks ago, before it worked perfect. Most of times dcing 3 times per hour. But sometimes working for hours without dcs. Usually disconnects only for half minutes then reconnect, it can be very annoying. The provider keep saying that need change router. I'm tried three different of routers already, but keeps disconnecting. I'm tried connect the net directly into my cpu, without router, but not worked, dc-ing too. I tried ping the default gateway when its disconnected, and its saying: request timed out.What else can i try? It should be, that the provider has too many clients, and their router collapsing?

We recently moved and upgraded our internet service from 1.5 Mbps to 4Mbps with CenturyLink. However, since our service was activated last Thursday, the internet connection intermittently drops and will not recover unless I reboot the modem. The period of up-time will last anywhere between fifteen seconds to several hours, usually falling along the five-to-ten minute range. No difference when using ethernet/wifi. The DSL light stays on, and the Internet light remains on as well.

I have a brand new Dell laptop running windows 7 connected to a sky router wirelessly. My internet connection randomly just drops. At 1st I could just click on the yellow triangle and troubleshoot and it would reset the network adapter. I cannot do that now - Im having to disable the adapter and the enable it and Im back on the internet.I have set it up so I am connecting via a manual IP address as I wondered if when the kids PS3 was connecting it was pinching my Ip address.

I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

isp is Comcast. They have had 2 techs come out here to look at problem and found nothing. I'm on a wireless connection with router in the next room. Modem was replaced a week ago and still problem persists. Landlady says she has no problem (shes the one in the next room and is connected directly) but I think that because she doesn't notice (I play online games so its very noticeable). I have excellent signal from router. This is my report:

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

We have about 15-20 APs out in the field, and at random they seem to disassociate from the WLCs and re-associate within a few minutes. We have not looked into that entirely yet, but we are having an issue with a few. Sometimes, they will disassociate and after a few hours reassociate.

I have a 2911 router hanging/freezing at random times, could work fine for a week then crash, or sometimes, could only go a few hours, completely random with timing. The onyl fix is to manually pull the power and reinsert.When this happens, all services/access stop working, including nothing on console access.This was on 15.2.1.T1 which im aware, has a few bugs, so i upgraded to 15.2.1.T2.The issue continued, so I swapped out the 2911 with a brand new one. The issue is still present.
One interesting thing, is when the router crashes/freezes, all lights appear to remain on working as usual, but when i unplug any of the ethernet links, the lights still continue to remain flashing and on for the ethernet LEDs, even once i have fully removed the cat6 cable.

I check all of the settings and changed the channel to see if it works. For some reason it disconnects my wireless internet at random times and i know before it never use to do that before with a older router. There is nothing blocking it, it worked before, and my computers can connect except two. The only thing i can guess is my wireless card.

The wireless drops specifically from my laptop constantly at random times. When the wireless drops in order for me to be able to reconnect i have to restart the router itself. There are also random times where the Wi-Fi stops broadcasting altogether. I have a computer connected via Ethernet and it does not lose connection during these times. All the computers are running Windows 7 and the Router is up to date on firmware.

Had an E4200 for a couple of months now and have not been able to resolve an issue with the router dropping an Apple iPad 2 at random times.The E4200 is replacing a Cisco Aironet 1200, which never dropped any clients, iPad 2 or others, and never displayed any of the issues below.
TECH DETAILS:The E4200 is being used purely as an access point. All extras are not in use and are disabled.
Firmware 1.0.03
Hardware version 1.
BASIC ISSUE:The E4200 drops an Apple iPad 2 off the 2.4 Ghz Mixed (B, G, N) network. The user must then select the network to rejoin. Rejoining occurs without incident. The same issue occurs when the network is restricted to B, G. The drops occur at what appears to be random intervals - sometimes 10 minutes apart, sometimes hours apart. We can have as many as 6 drops in an hour. A ping to the apple ipad shows the device stops responding to pings about 10 seconds before the user is prompted to rejoin a network. Meanwhile, a ping to the E4200 itself from a laptop connected via the E4200 on the same radio as the ipad continues to work without fail during this incident.
1. The iPad 2's cannot connect to the 5Ghz radio. I believe iPad 2's are supposed to support 5Ghz.
2. Both our Apple TVs do not connect to the 5Ghz radio: they fail with a "There was an error connecting to the network. Check your settings and try again. (-3914)" error. Apple TV supports 5Ghz.
3. The admin interface for the E4200 is very slow sometimes. Probably over 20 seconds to render some pages when it gets really bad. As a comparison, Internet-based pages on fast sites that delivered via the E4200 itself load in less than 2 seconds.
4. The HTTPS version of the admin interface can only be connected to via Safari browers. Both Internet Explorer 9 and Chrome 16 fail to connect with a "Connection reset" error. In Chome, it says "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." This is across multiple devices. There is no issue with straight HTTP.
All other devices - including Macs and PCs - connect fine with the E4200 on both 5Ghz and 2.4 Ghz radios, even if they cannot access its admin interface via HTTPS.I've presented quite a few issues above, but the main one is the drop outs for the iPad 2 devices. I'd present logs on drops, but the thing doesn't record any useful logs.
Basic wireless config:
5Ghz:
Network Mode: Wireless-N Only
Channel width: Auto (20 or 40 Mhz)
Channel: Auto (DFS)
SSID Broadcast: Enabled

We currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times. There is plenty of power left for the switch to use. We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch. If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline. We have contacted Cisco TAC and they just RMA them.

recently I've noticed sharp spikes on both my wireless and wired network connections, It's safe to say it's not a network card problem as all PCs are experiencing this problem. I ran a tracert and these are the results:Tracing route to [URL] [209.123.109.175]over a maximum of 30 hops:
1 4 ms 3 ms 9 ms 192.168.1.1

9.41]
[code]...
Trace complete.As you can see there is packet loss and a huge spike in ping time.

i've got a Dell laptop and a few months ago i started experiencing higher ping on some games and some spikes on the internet, at first i blamed my isp but this has continues since then and my brother has reported no spikes or ping increases in the last weeks. I experience a 120 ping on speedtest.net (on average) to servers that i used to get up to 20 ping on and i experience 200 ping on league of legends servers that i used to get 100~ ping on.My laptop is running on windows 7, using panda antivirus and spybot search and destroy (i uninstalled mcafee).

try to play online games but i can't because i get so many ping spikes. I started investigating and i've noticed that i'm getting ping when pinging my router. I'm using wlan and i can't use ethernet. Also the bandwidth is really low on the connection, 512 kbps Also, there are more than 1 computers connected, even if they dont use the connection constantly
