Motorola SB4200 / Continuous Ping Spikes Of Around 50ms?
Jan 26, 2011
We've had our internet provider and the same setup for about 5 months before this with no problems. I first noticed this in gaming. My ping will stick to around 40-50 in a server, but continually spike to 80-100. I don't notice it all that much, but on others' screens I'm choppy and look laggy.I'm connected to a router, but it seems to happen while directly connected as well. It has nothing to do with others on the network either. The modem is old, not sure if that has anything to do with it, a Motorola SB4200.
I have a Motorola modem SURFBoard SB4200, along with a wireless Linksys router that connects to that modem. The router works normally but the modem often dies and restarts itself after about 1-2 minutes.
What could be causing this problem? How should I start debugging it?
Could an excessive amount of network traffic be bringing down the modem? Are there any tools that can monitor the modem?
I have Comcast cable and prior to a couple days ago, it has always been smooth @ 36mbps download and 5mbps upload. I have a Netgear WNDR3700 and Motorola 6121 connected to my PC via Ethernet cable. Up until a couple days ago, I've been getting lag spikes where my games would completely freeze for a good 2-3 seconds and resume, as if the entire connection dropped and reconnected. I did a speedtest and I was getting around 4mbps download and 1-2mbps upload with huge fluctuation in speed.
I called Comcast and they said they were seeing a "red" signal error from their end so they sent out a tech to my house. He came over, changed some cables outside because they were corroded and that's about all he did. I tested my connection while he was still there and I was again getting 36mbps download and 5mbps upload. It was a quick 1-2 test so everything seemed normal until I started to see lag in games again.
I am getting the same lag spikes, albeit it's not as bad as before but it's still pretty annoying. Using speedtests, I am still getting 36mbps download but the graphs show that there are inconsistencies where there would be sudden drops in speed and picks back up still to show 36mbps. These drops are what I assume are the lag spikes. The upload is also suffering now, dropping down to 2-3mbps and it takes the test about 20-30seconds to load the upload portion of the test. Even loading web pages, sometimes it locks up for a few seconds longer than it should, which is normally instantaneous.
I have tried connecting my PC directly to the modem to bypass the router and am still getting the same lag, probably a little LESS but still the lag is there. My router is has always been updated to the latest firmware.
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 2 242 ms 33 ms 29 ms 10gi6-0-0-100.bras1ldv.akl.vf.net.nz [203.109.12 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
the problem is that I'm suffering from ping spikes. When I ping my router it looks something like this:
C:UsersNiklas>ping 192.168.1.1 -n 10
Skickar ping-signal till 192.168.1.1 med 32 byte data: Svar från 192.168.1.1: byte=32 tid=991ms TTL=64 Svar från 192.168.1.1: byte=32 tid < 1 ms TTL=64 Svar från 192.168.1.1: byte=32 tid=2944ms TTL=64[code].....
my ping spikes to 1k+ all the time, making online games pretty much unplayable. Sometimes I'll lag up to 3k ms and by the time my ping is back to normal, the game is so behind it is messed up forever.I've looked online for days trying to find solutions, and trying all kinds of things. The problem started after i reinstalled windows xp (it actually started right after my power flickered after i reinstalled, but i think that may be coincidence. I'm not sure though.). I've reformatted since then, but the problem still persists.I think the problem might be WZC, but when I try stopping the program like other people have done, my wireless network disconnects pretty soon after. I've also tried just using the intel software, but that didn't work either. It was fine for a while last night after I changed to the intel software, but after maybe an hour or so it went back to lagging.I have Intel PROSet Wifi agn 5100 as my network card. I'm on a laptop. I also tried doing a ping test in command on my mom's laptop, and it never spiked like mine. Is my network card maybe just too old? I got the laptop almost 4 years ago.
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.
I was having very high ping spikes (up to 2000ms) in my online gaming. I even had high spikes (up to 80ms) just pinging my router. It happened with every computer on the network. After several weeks, I narrowed it down to one thing: Enable DNS Relay. I unticked that, and instantly the spikes went away. However, my brother's Blackberry Playbook has been acting up now that DNS Relay is disabled. Basically, every day, the internet on that thing screeches to a halt, forcing him to reconnect to the network. It's basically a minor inconvenience, but it's one I want to correct. If I turn on DNS Relay again, the ping spikes will return. Interestingly, I switched ISPs during this time. I'm on cable now. I used to be on DSL with a different router, yet I had the exact same problem. The blackberry is probably integral to this problem. So I'd like to know if there's anything I can do to make DNS Relay work properly, allowing his stupid Blackberry to work, while maintaining the integrity of the network.
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 have 2 computers hooked up to the router via wire and wife using wireless on her laptop.I'm playing games on internet and soon I noticed I got occasionally ping spikes.. The ping get beyond 1000 - 1500 so the screen is in fact temporary freezed. Sometimes those spikes can occur with 10-15 minutes inbetween them sometimes it can be an hour or more before I notice it.I'm running Windows 7 on both my computers. I first thought it was Microsoft was to throttle the packets so I did the change in the registry. But these spikes still happen. After some testings I also notice they happen at the same time on both computers so my conclusion is that it's something with the router.
It is understood that sub-50 ms ERPS convergence can be achieved with certain HW/SW combinations.
1) What are the platforms supported (and with what FW/SW) has this been tested ?any results that can be shared?
2) Link failure detection in GigE on Copper is slower compared to GigE over "pure" Fibre; so no sub-50ms would be possible with Copper ring ports.is sub-50ms convergence achievable with "combo SFP ports" ?
I have recently buy Dell n5520 Core i3 ( 3rd gen) and have download all the drivers dell have recommended and installed but my WiFi is not working its just connect to my WiFi router then disconnects after 2 or 3 seconds .. While troubleshooting it connects to my WiFi router but then again disconnects and after this disconnect it will never reconnect until I disable and then re-enable the WiFi adapter.
After the driver installation the adapter says that it is working properly , in device manager > network adapter > properties , but actually its not connecting ...

When there's more than the usual (3) computers connected to our home network, i suddenly get internet problems which includes continuous disconnections from skype and wow (That's those I've noticed so far).Calling my ISP won't work because they will only say that since it's only my computer then it isn't their fault etc.
I would like to record the camera feed (per 5 min. files) on my server (ubuntu or windows)
I Installed a FTP server and tried the option "always" in the "video clip" section, but unfortunately, it seem not possible to record more than 10 seconds files every 60 seconds . I think that this is a bug ?
Do you know, if we have a possibility to record the camera feed, I would like to manage it from the webcam or with an external program running as a service.
I have a new TEW-692GR router attached to an UBEE DVM3203B cable modem. For the last several days the WAN light on the router and the LINK light on the cable modem flash on a continual basis. This seemed to happen after establishing a wireless connection between a new LG smart tv and the router but am not sure if that in fact caused the issue. I have power cycled all devices on my network in an attempt to clear this up but no joy.
I've tried to upgrade a redundant setup from 8.2(4)4 to 8.2(5)22 ending with a stanby ASA continuously crashing after config sync phase. On the first crash it even corrupted the flash, leaving me no choice than initializing the box from scratch.
we have a Cisco ASA5550 and stuck into continuous rebooting loop. it show an error :assertion "_vf_mode_init" failed: file "vf_api.c", line 99
Earlier it has an 4GE SSM module, for some reason we want to utilize 4GE SSM module and we unplugged and after that we face this issue. Error message file is attached.
My iphone wireless connectivity to my Linksys router that I have put up with for a year, but as I now have the same issue with my ipad I've decided enough is enough.The issue is that they both connect OK to the router and therefore to the internet, but after a short period of time (minutes) whilst it appears that they are still connected to the router the connection seems to completely hang. At that point I have to go into settings on the iphone/ipad and turn off the wireless connection and turn it on again. This then allows connectivity and internet activity for 5-10 (15-20) minutes before it hangs again.I have no problems with connecting to any other router from the iphone and ipad. And I also have no problems with my PC's connecting to the Linksys router.

I've Dell Inspiron n4010 with windows 8 OS. The problem is while I'm working, the network adapter will disconnect suddenly. In the previous OS windows 7 I faced the same problem. The only way to get it connected again is through restart.
Just this weekend, my DIR-655 has suddenly started blasting out continuous IGMPV2 Membership broadcasts, causing a flood of network traffic that's not normal and is interfering with other traffic. Rebooting everything in the system didn't fix it, turning off the other machines on the network (3 + NAS) didn't fix it, and I couldn't find anything in the configuration of the DIR-655 to stop it.
I have an SG300-52 gigabit switch that has been constantly rebooting and is effectively unusable.This started after Enabling TCP Congestion Avoidance, specifically:
-Turned on TCP CA -Saved Running Config -> Startup Config -Rebooted Switch
Since then the switch has been rebooting roughly every half a minute, and the management (HTTP) interface is inaccessible. In addition the factory reset (i.e. reset button for greater than 10 seconds) does not make a difference. I suspect that there is some bug with TCP CA that causes the switch to fail to start up, and that factory reset has failed to clear the startup config.
Continuous dropping out some of them Access Points registered on the Primary Controller . What is the reason for this. We have a problem the last 2 weeks. What are the causes of falling out controler Access Points. The problem does not appear from logs. 70 LWAPs registered over Primary Controller. All AP mode is Local.
Every night I turn everything off via power strip, including the router. Before I turn off the router, my roku connection is good.In the morning, the roku will work for about 20 minutes, then disconnects, and then I'm unable to find the router.I'll then need to reset my router's settings (I have the WRT54GS), and then uplug, and replug the router.It's important that I unplug the router every night.Is there a way to configure the settings so I don't have to reconfigure the settings every morning?
Looking for a SOHO device that could accomplish not only to connect people from home to Internet, but also to let me remotely access my work stuff (from my home office), RV180W sounded great and really cost effective. I could connect to Internet, FROM Internet, separate home, work and guest VLANs, all in just one device... sounded just GREAT! Bought one but (unfortunately) I have to say I'm quite disappointed with its performance, outnumbered errors (how many!) and continuous lost of Internet connectivity (can't stay a full day without one).I've searched a lot (not only here) and tried many things, listing some:
- Upgrading firmware (now v1.0.2.6): done several times, once with nothing connected to the router besides a local wired laptop, to ensure integrity - Resetting to factory defaults and performing a "clean configuration", from scratch (done several times) - Disabling Firewall functions (once all of them) - Checking the real need of every option and making sure I had just the ones I needed configured
I have (in a very "consistent" way) the following problems:
- Poor performance (it's clearly much better when I directly connect to the cable modem's WiFi OR to another router connected to this cable modem). I could say that it seems to have 50% of the performance I had with my CISCO/Linksys E4200 and Netgear "elder" routers.
- Persistent disconnections / resets: Sometimes it happens only with wireless, sometimes it looses the "Internet forwarding capability", retaining the local wireless connection (to other devices), sometimes it seems to make a full reboot (including a new DHCP request to cable modem). In a day this happens several times, I'd say from 3 to 15 times, depending on the day (couldn't figure out why).
CPU utilization is always shown as being 100%, what sounds amazing, because:
- There are usually just 4 wired connections (3 storage devices + 1 Desktop) and at most 5 wireless connections (including my laptop connected to the main VLAN and 3 Android devices and 1 "guest" laptop connected to GUEST VLAN) - The utilization % remains when I have jut one laptop performing Internet browsing and nothing more - VPN wasn't enabled yet (and it will be, as I want to remotely connect to my home office) [code] ......
I have Nexus 7K installations in 2 locations. Both of them have multiple VDCs. In default VDC there are continous tacacs error message though tacacs is not configured. The requests are from various public IPs where thsi VDC is not exposed to Internet at all. What would be t he cause of it?

We are running a stack of 2 WS-C3750X-24S-E's with IOS version 12.2(58)SE2 and we are seeing continuous high processor utilization involving the hl3mm process. The stack is configured for PIM Sparse mode, with 2 upstream Nexus 5596'es acting as both RP candidates and as BSRs. The hl3mm process generally runs at about 19% but can spike up into the 60% range.Symptoms on the 3750X are spiking latency and sluggish CLI perfformance. I thought at first that we might be running into SDM limits, but the "show platform tcam utilization" show that we are far under the limits of the default SDM template. Performing the "show ip pim (vrf name) bsr-router" command freezes the system and takes 20-30 seconds to return results. Similiarly configured WS-C3750G-12S running 12.2(55)SE3 does not exhibit these same issues.
Since about a week ago, my room-mates and I have been getting lag spikes on the internet when more than one of us are on the internet at once, yet the connection is perfectly stable when there is only one active. ( Does not matter which one. )
I've run Avast, AVG and CCcleaner, on all the computers and the spikes still persist. I've also replaced my router with no results. Here's my system info and some tracerts showing the lag spikes
System info:
Tech Support Guy System Info Utility version 1.0.0.2 OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 64 bit Processor: AMD Athlon(tm) II X4 640 Processor, AMD64 Family 16 Model 5 Stepping 3
About 2 weeks ago I have been getting lag spikes on my xbox and PC games, this never happened.I have no problem playing the game, no lag. Apart from these spikes that happen every 10-15mins.They last for about 5-10 seconds and seriously affect my game. (I get killed) Would switching channel through the 02 Wireless internet control panel fix this? Am I on a bad channel?p.s. It is not possible for me to haveit wired, wireless only.
I've been having problems with my internet on my PC. I use it mostly for gaming (League of Legends specifically but it's also hooked up to my Xbox for internet connection), and I frequently (about every minute or so, sometimes more) get bad lag spikes when playing games. My character will freeze in place while I click wildly about and then appear somewhere else (and die or lose a kill).
The thing is, I'm connected to my Apple Airport which all other devices in the house are connected to (Wii, dad's Mac desktop, my Mac laptop), and only my PC gets this lag. Seems like a fairly generic problem but I have no idea what to do about it, so if you need more information let me know.
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.
