Linksys Wireless Router :: WRT54G Receiving High Latency Spikes And Total Connection Loss
Mar 10, 2011
Product: Linksys Wireless-G Broadband Router WRT54G
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 decided to change my old Belkin router to a Cisco one, and ever since i've got all sort of problems with internet connection.I'm a gamer, and my brother as well, and with the Belkin router we never got any issue, but now when we try to play together online we get serious Ping problems (We usually play at 80ms, but for a couple of seconds it reaches 800ms.. then it goes back to 80 ms).I have a 20 mb Conection with no P2P restriction, I'm using only Wireless-N connection, with only 20 Mhz and in Ch. 9 (2,452 Ghz).I also use a WPA2-Personal password and QoS System to give more priority to my PC and my games (DotA2 and WoW).This problem only happens when we try to play 2 games at the same time (e.g. DotA2 and WoW, or DotA and DotA, etc). Well i actually think Cisco might be better (Well, I payed extra money for "quality") but then again, with all those problems.
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 this game, Chivalry Medieval warfare, 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.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... 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. I also notice there is a delay of a second or so before I start to load a webpage when I click a link.
Can your wireless router do a ping test to 184.108.40.206 [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
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 have the WRT54G v2.2 router. I have Comcast internet service. Comcast has just increased their internet download speed to 50Mbps. With a wired computer (not wireless), connected directly to the router, the fastest internet download speed I get is 30Mbps. When I called Comcast's technical support, they are telling me I need a new router as the older routers can't handle these high internet speeds.
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.
After an upgrade of the WRT120N to firmware Ver.1.0.06 (Build 01) every device I have tried to use WPA authentication with will authenticate / associate with the device then drop the connection just prior to recieving a DHCP address.I have tried a Dell latitude laptop with the broadcom chipset, an iPhone 3GS as well as an motorola with google pad device and all experience the same problems.I have removed all mac address filtering, and re-enabled the essid broadcasting only to have the same problem persist despite stripping everything down to just WPA.
my latency values are extremely high, sometimes millions(!) of microseconds. THe problem is always solved by disconnecting the 11b/g wireless LAN adapter, or the Intel(R) Gigabit Network connection. However, I can't work without internet.
I have a WRT54G2 router (V1) with the most recent firmware that serves as the gateway between my Internet connection and my home network. Over the past few months, I've noticed that the router seems to consistently become unusable due to high latency when it runs for any period of time. The internet connection is working, but the latency is sometimes as high as 2000ms to ping Google or to run a test from Speedtest.net. When a computer is directly plugged into the cable modem provided by my ISP, the problems resolve.
Restarting the router proivdes a resolution of the problem, but over time the latency issues increase again until it needs to be restarted. Right now, I have it on a mechanical (plug) timer that restarts it every morning around 4AM, but this still doesn't seem to fix the overall issue; I've had to restart the router manually twice today. Before restart, my ping will be over 1000ms; afterward, it will drop back to 20-60ms.Note that the download and upload speeds don't seem to be affected by this, just the latency itself.
The problem appears on both wireless and wired connections.I'm not sure if this is a sign that our router is failing (it was purchased in 2009, so as far as consumer-grade solutions go, it's lasted a pretty decent span), or if there's some misconfiguration on my end, or if something with my ISP is making my router flip out. What can/should I do to fix this issue (please note that flashing the router with DD-WRT is not an option, this version generally sees decreased performance when DD-WRT is installed).EDITED TO ADD: I have ruled out internal traffic causing the problem (I reviewed the log files for the router and tried to identify any unknown stuff, but it seems fine). I can't quite figure out exactly what causes the router to develop the issue, but once it does, I've noticed the following:
Extremely high latency (1000ms+) for pings from any computer inside the network to an outside destination?The router itself cannot ping or traceroute once it has started developing these high latency issues - if you use the router's PING feature, it returns all timeouts.It does not seem to correlate with any specific type of traffic.
When using this laptop (Toshiba Satellite C660D-1GD) on the forum it seemed unusually laggy when changing pages, whereas when using my Toshiba Satellite L450D it is always more positive.Decided to do some ping tests via the cmd prompt (after checking the error count via telnet) and they were in the hundreds.The L450D ping tests are spot on so I know it isn't the router (Billion Bipac 7800N)Been the usual route, totally uninstalled the wireless adaptor (Realtek RTL8188CE Wireless LAN 802.11n) including the Cisco elements, Eset and MBAM full scan and downloaded chipset drivers. Even factory reset the router and deleted the wireless profile including reg entries as a last resort.After each of those operations (other than reinstalling the wireless adaptor) the latency would be spot on and continued to be after an immediate reboot, but logging on a couple of hours later or the following morning, they would be very high again.After reinstalling the wireless adaptor for the second time, on a hunch I removed the Ethernet cable and run another test. The latency came in high but when I re-ran the test wired, they were spot on.
Phoned up KnowHow techs and read off the numbers who then put me onto 2nd level tech. He remotely connected and ran a couple of ping -n 50 tests as well as a tracert but was unable to replicate the results I was gettiing. As nothing was broken (for him), nothing to fix but to phone again if it continued.I rebooted after the phone call and got the high latency straight off. I wondered, as the latency returned to normal after certain operations I'd done, whether the remote connection had the same effect.Having been on the phone for 55mins, I'd had enough.These are two tests I've recorded from today which are together in one Wordpad doc, so you'll be able to see what I mean. Ctrl+C has been a bit erratic so they are the only ones I've been able to save. [code]
Having several issues w my E1200. For quite some time I have had intermittent loss of internet connection. This was somewhat true even before I got a wifi router. & it has continued. Recently it has been even worse & I'm not sure if it is my isp, my cable modem or the router. ISP came out & checked & said signals looked ok, although modem is old.Now i find out that the version of Cisco Connect that i had been using is incompatible w Mountain Lion so it won't work now. & newly downloaded dmg files say they are damaged (or that app has been modified or damaged--I'm not in a position to tell which but same results after I downloaded a 2nd time).
I have been having more frequent loss of internet connection at home. & when I click on the wifi icon to check, it shows it looking for networks. Also it has not been uncommon to see that it has switched to my guest network.Why would it switch to my guest network? What is the difference between the 2 besides the fact that I guess the guest network doesn't have access to everything on my regular network (which right now is only my iPhone, but may get wireless printer).Also when it shows the lists of networks that it "sees" my guest network does not show a padlock icon so what does that mean? It does have the default password.
Also because I had no idea that Cisco Connect was not compatible w Mountain Lion I didn't even think to check for upgrades before I upgraded to Mountain Lion & now I can't open Cisco Connect. Shows unsupoprted OS. & I'm also stalled trying to update the firmware for the router.I'm really beginning to see why it was cheaper than an Apple Airport Express. Even at a very low hourly rate, the lost time spent when this has not been working right has not been worth what I saved on the purchase price.
I work for a small college. We have several Cisco 1200 Aironet deployed our the campus, all of which are configures to run multiple SSID's. The problem I have is that when I connect, via AP, it successfully connects to the desired SSID but on pinging the default gateway of said SSID I get high latency (avg around 100 - 200ms).When pinging from the switch (Cisco 2950) to the default gateway the latency is good (1-2ms). It is just high when I connect via the C1200 AP and try to ping.
Our database server is connected on cisco swich 2960G gigabitEthernet 0/38.while showing the interface command the total output drops is a large value..Is there any issue with this value.I think this is one of the reason for slow access of the server.
cisco6#show interfaces gigabitEthernet 0/38 GigabitEthernet0/38 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 58bc.2746.45a6 (bia 58bc.2746.45a6)
I've tried all sorts of settings, and I'm still holding out that its a setting possibly, but I have a E3500 and devices on both 5Ghz and 2.4Ghz... Most of them, probably when idle, seem to stop working over WIfi. They still have decent connection, but every internet related request just times out. Disable and reinable the wifi and it works great again.
Could this be defective wifi radios? or could it really be interference? I have it happening on multiple devices. Also, I'm not far away from the router when it occurs, and when I reconnect, it seems to work just fine for a while. Basically the big problem is on the cell phones and tablets because I'll miss notifications... I'll turn off the wifi and turn it back on when I use the device next, then a flood of notifications will come in. Again, it's not just a phone thing, tablets and laptops have the same problem, that's just the main reason I want it fixed.
I have been spending days !!! trying to resolve why my laptop pc disconnects frequently from its wireless connection. No discernable pattern to disconnects, totally random. Happens in cycles of disconnect/auto reconnect or will go hours of stable operation. What I have noticed is tht the connection speed seems to vary, from a hig of 54.0 Mbps to as low as 2.0 Nbps. At same time the desktop pc (hard wired to modem) stays connected at 100 Mbps.Using RCA modem, WRT160n v3 router.
I have the same issue with Toshiba satellite AA665D-s6091 I expierience crackling sound when playing. peaks appeared when I had either the (cable and wireless) adaptors enabled, when I enable/disable the backlit keyboard and also when I enable/disable eco-mode.A Windows and driver update fixed the cable adaptor issue.
I ran the commands in post #19:
netsh int tcp set global autotuninglevel=disabled netsh int tcp set global congestionprovider=ctcp netsh int tcp set global dca=enabled
The wireless adaptor issue was fixed with these, however every time y enable/disable backlit keyboard or eco-mode on my laptop I still get this latency peaks around 18000 us and audio clicks. I check latency with DPC latency checker V1.3.0?
I have an E1200 and am time out and packet loss issues. The internet connection is fine for 30 seconds to five minuets and then everything times out for 15-20 seconds. Although it’s only a minor incontinence to web browsing, it makes playing games and watching videos a nightmare. “Lost connection to server error.” and the like…
I upgraded to a new router, the e1200 I am currently using, from my Tenda 10/100 N. The problems where the same that I am experience currently and the reason I bought it in the firs place.When I directly connect to the cable modem, I have no issues and everything is fine.I have run a trace route and the second hop, (the router to the modem) is the choke point.I have cloned the MAC address.I have updated the firmware and hard reset
I have throttled my MTU to automatic, 1500, and 1472. None making any difference.I have disabled NAT and all that does is kill my internet connection.I have disabled all firewalls router and windows, no change.I replaced the physical wire from the router to the modem.I have disconnected all devices except one computer, and no difference.I ran a DNS trace and I have… non routable local internet address 192.168.1.1 DNS-cac-lb-01.rr.com and DNS-cac-lb-02.rr.com.I am using windows 7 and my ISP is time Warner so-cal.
Over the last couple of weeks I've been noticing high amounts of jitter and latency over my home network. I've come to some conclusions but am not 100% sure if they are correct or not.When one computer on the network opens a web page, loads a video off youtube or downloads something all of the computers on the network have considerably increased latency for a short period.I've tested 3 computers over WiFI watching ping commands and will show some below in a moment. Tested 1 computer using ethernet to connect to the router and its still affected by the issue. Ive also actually used the router to ping an outside source while the ping is increased and this is also affected. This has only been happening for the last 2 weeks.
Heres a list of hardware being used/software and os.
Windows 7 with a Belkin G enabled usb NIC Windows XP with a realtek rtl8139/810x Windows 7 (Friends laptop) Router = Netgear dg834g Settings
So I've read up on QoS and understand that my router doesnt support it but I still dont understand how 1 person using youtube can affect my network that much. As before 2 weeks ago it did not affect it what so ever, and it didnt in my old house either. So what this means is that browsing is fine on the network, just whenever you try and play a game or anything that requires low latency anyone touching the network means you get massive jitter.
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] [220.127.116.11]over a maximum of 30 hops:
1 4 ms 3 ms 9 ms 192.168.1.1 2 242 ms 33 ms 29 ms 10gi6-0-0-100.bras1ldv.akl.vf.net.nz [203.109.12 9.41]
Trace complete.As you can see there is packet loss and a huge spike in ping time.
When it comes to networking and require some advice on setting up my wrt61on router with my airport express. I have managed to get it all connected up and working but am suffering frequent dropouts while streaming music. I have done a little reading and have tried changing a few settings on the router but have found no improvement. My set up is as follows.
-Modem connected to WRT610N Router -Desktop Computer connected to network via wusb600N dongle -Airport Express connected via wif -Using Iphone 4 as remote
Is there a way where i can set up the airport express on a total different frequency to everything else in the house i.e laptops iphones etc to prevent these cutouts.
So I am at a bit of a loss here. For the past week or so, I have been getting random spikes of high latency in online games like World of Warcraft/Star Wars: The Old Republic/League of Legends/etc and I have no idea what could be causing it. My ping used to run around 30-80 and lately is has been spiking from 100 to over 700 randomly. I have tried everything I could think of like not using my router, power cycling my modem several times, making sure my drivers are updated, no programs in the background causing it, no firewalls/anti-virus programs causing it, and several other little things like that. I have also called my ISP and they said everything seems to be working fine. And here's another weird thing, according to speedtest.net, my service is running as it should be: [URL]. The server my service is connecting to is in the next town over which is ~15 minutes away so that couldn't be it either.
Here is my system specs:
OS Version: Microsoft Windows 7 Ultimate, 64 bit Processor: Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz, Intel64 Family 6 Model 26 Stepping 4
As of late whenever I, or any of my roommates, browse the internet we have noticed a slower browsing experience, where pages used to load instantly, there is now a noticeable delay in accessing web pages. Also, in playing online video games, whether it be on the PlayStation 3 or PC gaming, high latency is always present. The problem is present whether there is one computer connected, or five, Mac or PC, Wireless a/b/g/n or if connected through the ethernet port. What I ask is: What causes such behavior, and what can I do, if anything, to resolve this issue?
Running a DGL-4500 D-Link Router with Comcast service.
A trace route to google shows the following: C:UsersAdministrator>tracert www.google.com Tracing route to www.l.google.com [18.104.22.168]
Situation: I have one Internet connection and I have need of two networks. One filtered with OpenDNS and the other unfiltered. I have a Speedstream DSL router provided by ISP for connecting to Internet. I have two WRT54G's and would like to utilize them to form two networks. The Speedstream is a router with a gateway address of 192.168.1.254.
From that Speedstream (only one network plug) I would like to go to a 5port switch. From that switch, I would like to configure the two WRT's to be two different networks (one using OpenDNS settings for filtering) with one having a 192.168.1.x address scheme and the other (no Internet filtering) having a 192.168.10.x scheme. Both would have DHCP enabled for their networks and the Speedstream would have DHCP disabled. There is not a need (at this point) to have the networks communicate.
Ive had a WRT54G v5 for awhile now. And just recently I went out of town and had turn off my router. When coming back and turning everything back on for some reason both wired and wireless components both have a connection then it loses the connection for awhile and comes back on. Ive power cycled both the router and modem. Called my provider and they said it was my router after doing some diagnostic tests. I tried to update the firmware and ive tried to restore to factory settings. Still it has a connection then it loses it.. Ive noticed on the modem when its not working that only the SENT light is flashing. (modem has power,received,sent, cable,pc). It is on AUTO DHCP and gets a ip and everything.
last weekend i configured HSRP on our default gateway(Cisco 2600) and now i have the problem that the latency is constantly at 3ms and from time to time it goes up to 10 ms. Is that something i should have expected or is there someting wrong with my configuration? The standby ip adresses are the same adresses as the router interfaces had before and the CPU utilization is at 10 % so i do not know what happend here. I atached the config file so if you need further information i will gladly provid it.
\We have purchased AP 1041 and WLC 2500 and I am doing a testing on the configuration. It is fine when both AP and WLC are sitting on the same network. However, if I connect the AP to the WLC which is on another network, I found that latency is quite high when PING the gateway. Here is the brief topology.
I have cisco 2811 at branch and 3845 at Head office. Two link with 256 kbps bandwidthe each. I did as follows: [code]
When link 1 down, traffic change to Tunnel 2. its OK.I want when link1 flaxuate or latency high (more than 60 ms) traffice change to tunnel 2. If link 2 goes high latency automatically change to tunnel 1.
