Random Instant Disconnect / Reconnects While Uploading
Dec 3, 2011
Basically i'm an employee of a Pro-Gaming team, and as a Job I stream games live, as well as upload game videos to youtube. I've been encountering a problem for a month or so now and had little success of fixing it, which is costing me quite a lot of money and viewers! Basically, I use a program called Xsplit to stream to a website called Twitch.tv (no-one else i've spoken to has the problem I have). I will randomly disconnect/reconnect instantaneously which puts my stream down for 5-10 seconds at a time, then goes back up again. Ultimately the viewing experience is ruined by this and I am on the verge of being replaced!The problem can occur either once a week or once every minute.. it just does it whenever it wants. I have 200mb/10mb internet so my upload should in theory not be an issue.
Things I have tried and done so far:
- Replaced the Ethernet Cables.
- Replaced the Routers.
- Bought a Network Card to try as opposed to my Motherboard port.
- Reformatted my computer and installed a different version of Windows 7 multiple times.
- Spoken to Twitch.tv and Xsplit about their programs as well as used multiple versions of the Xsplit client.
- Spoken to my ISP who say everything is fine.

Ill get on my laptop and it will connect for 45min-hour and then it will disconnectEverything says connected on the laptop and the router and modem are connected and working. I have tried restarting my router and modem and even clean installed windows and reinstalled drivers. Nothing seems to work. Im posting from my old laptop and it seems to happen on this computer as well. This has never happened before.

Recently I bought a new PC to replace an old laptop that I use in my bedroom. However, initially I couldn't pick up my downstairs router signal. So, I bought a new wireless network card and STILL didn't pick up any signal. I then purchased a Netgear WN200RPT and everything seemed to be ok while using that to repeat the signal up into my bedroom. Then, suddenly, it all stopped working. The WN200RPT would, although showing a full internet connection with no yellow ! or red x's, it would never ever load webpages. So, I removed it and put it back in its box. Then, for some unknown reason after a Windows 7 reinstall, my network card started picking up the signal from my home router and had a good speed and signal. This worked fine for a month or two before it started playing up again. It would randomly slow down and stop loading webpages, or completely lose the signal and show a red x, stating that no signals could be found. The strange thing is, all the other PCs in my house connect wirelessly fine, and so did the laptop that was in the same room as this PC. After a system restore, the internet started working again. Then it stopped. Another restore later, it works. Now it's intermittent again.

When doing anything on my PC, gaming, browsing, whatever, I will have random disconnects for a few seconds and it will reconnect. I don't get the "your network cable has been unplugged" message, it just stops working for a second or two and starts working again. This has been happening for a few months after a fresh install of windows xp and I haven't really tried to fix it.Every other computer in the house is fine except this one, it can't be the modem because a new one was installed a few days ago and its the same problem. The router was reset within the last week as well. I think the problem is with this computer alone but I don't know where to look. The problem didn't happen for a few days after I put a new network card in, but soon after it continued happening. I also have tried a few different CAT5 cables, even the XBOX one but nothing resolved the issue.

Network Setup
===========
2 Site to Site VPN tunnels has been established, it is a hub and spoke topology. The hub is ASA5520 and the 2 spoke are a 1841 and 1801 router. The tunnel is able to pass traffic, it's a full tunnel VPN.The tunnel randomly disconnect for no reason. When I check the logs I can see some errors :
%CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid spi for destaddr=x.x.x.x, prot=50, spi=0x5F822579(1602364793), srcaddr=y.y.y.y
%CRYPTO-4-IKMP_NO_SA: IKE message from y.y.y.y has no SA and is not an initialization offer
The actual address have been replace by x.x.x.x and y.y.y.y. I frequently have to peform clear crypto isakmp on the spoke routers to revive the VPN tunnels. Is there a way the tunnel can be re-establish again without manual intervention?This keep happening on a random basis and I have living with it for years. I have looked at cisco website troubleshooting tips and but no luck in finding out how to resolve it.
Below is my config on one of the spoke router:

We have computers that are connected to a switch stack of 3 - 3750 switches. Randomly, we experience pcs that fail to communicate on the network. At first thought I figured the port went into err-disabled state, however the port shows up fine on the switch and moving the pc to another port on the same switch in the stack fails to fix the problem. To add to the confusion, if I immediately connect a different machine into the problematic port the newly connected machine has no issue and operates normally. Connecting back the first machine still results in no connectivity.
The only way to gain back network connectivity is to move the pc to a different switch in the stack. shut/no shut doesn't work.The IOS the stack is running is 12.2 and the switch ports are configured using cisco port macros.
here is how all the ports are configured.
switchport mode access
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
macro description cisco-desktop
spanning-tree portfast
spanning-tree bpduguard enable

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 my ethernet cable hooked up to a WNDR3400 router, and my internet connection will drop for an instant randomly (usually happens at least once every 5 minutes) it then instantly reconnects. The problem is that when i'm downloading stuff, the disconnection will cause the download to fail and i'll have to restart from the beginning (making larger files impossible to download). Also, I have an xbox in the same room connected to the router via wireless. It also has the same issues of dropping and reconnecting and that causes me to get kicked out of live.Interestingly enough, my laptop, connected to the internet via wireless does not experience this issue when used in (or outside of) the room.

I have an ASA 5505 and I setup a port with a PC connected to monitor the LAN interface. I see all the traffic from the LAN going out and traffic coming back in no problem. What I do not see the the AOL Instant Messenger traffic at all. I have WireShark on the PC and I filter for AIM traffic and I see nothing.

I was wondering why are upload speeds so much slower then download speeds with residential IPS. I know downloading is alot more common then uploading something. Does it cost more or something, for the ISP to send information out.

I recently bought my new Alienware laptop and it would connect to the wifi but no internet. Sometimes it works for a second or 1 minute. Now it's just a triangle with an exclamation mark saying it has no internet access. I already tried the power management. I am using a router; the other laptops in my house is fine. Could it be because the router couldn't support the internet of the Alienware? I remember seeing routers saying "Good for gaming!" something like that. I've been having this problem for 2 days now.

First this is my setup, i have a 100x100 mb fiber pipe at a location i am working at. i am comming out of a cisco fiber router to ethernet. i am coming straight from the fiber switch to the computer at a 1gb connection. So my problem is when i try to upload to my ftp server via windows explorer i can never get about 1.5mb, but if i upload via command prompt it goes at about 60mb upload, so the pipe is good. So you say why dont you just use the command prompt, well i have specialized gear here that run xp emmbedded and it does this via the windows explorer. I have tried 4 other computers and they all do the same thing. I tried a UDP video stream and worked at over 10mb stream. but all the ftp uploads cap out at 1.5mb.

I have a DSL connection with AT&T. It is rated at 6Mbps / 768Kbps, but it closer to 4Mbps / 600Kbps. I have a speed stream 5360 connected to the DIR655. Devices on my network are primarily wireless and include; several laptops, a desktop (which is wireless n), a couple phones / Ipods and a Wii that I watch Netflix on.
I do a lot of Photography and a handful of video work, and backup / share everything online. When I am uploading photos, even with "conserve bandwidth" turned on in the uploading application, browsing sites is very slow, but reasonably functional. If I try to upload a video to YouTube, I can barely manage to do anything else the entire time it is uploading. I've tried to plan and run all my uploads overnight, but then Netflix is unusable when I want to watch it at night.
I've tried several different things, first off, with getting the Wii to function for Netflix, I turned on the QOS engine, for the IP that is assigned to it, and set it to priority 1 for all ports. I also have a entry in the QOS engine for SSH on port 23 with a priority of 10 because of how laggy my SSH sessions are. I do not have any other entries in the QOS engine, is that a problem? Should there be entries that cover other services and assign them a lower priority?
I have enable traffic shaping and Automatic uplink speed turned on. It measured the uplink speed at 695kbps, which is pretty accurate. I have Automatic Classification off, and Dynamic Fragmentation on. WISH is enabled also. I'm set to mixed n, g, and b, I'm not positive, but I do think my older laptops only use wireless b.
Even more importantly than the Netflix would be to allow me to use the Internet in a functional manner while I am uploading, that would solve a lot of problems. It seems that the uploads just hog every last bit of upload bandwidth and don't want to make room for even the small requests that one needs to send to view a web page.

regarding my wireless card conecting to the internet.
Firstly what happens is I coonect to my hub which is a sky router without a problem, the internet isnt a problem and gaming and so on, but from time to time and sometimes once every 15 mins the wireless icon in the bottom of the screen says it has disconnected then a few seconds later it reconnects this may seem trivial but when i am playing games and surfing the web it gets extremely annoying getting cut off. I have tested this on another router and it is the same problem, so i know its not just one isolated router. stop the wireless connection from disconnecting randomly.

I'm having this discconnection and reconnection issue every 30-45 minutes, and it is extremely annoying. Especially when playing online, I always get disconnected from the server. I have tried so many things to fix it, but no change at all. I've tried to change my DNS, tried to plug the modem directly to my computer, but the problem still existed! When I troubleshoot from the windows, it says: your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.

My wireless internet constantly disconnects and then reconnects right away for seemingly no reason. I can't find a pattern, sometimes I have no dropouts for 6 hours, sometimes it happens every 20-30 seconds for a few minutes. I've checked online and i tried to do some research on it but i couldnt find an answer, i remember typing something into the cmd and it said that something was disables, just cant remember what i typed into the cmd. Also, when my ISP raises the network speed, my router or whatever it is can't handle it so i disconnect and have to call them to set it down.

We have 4 computers that all run new versions of Windows 7. Each have been connected to a Mapped Network Drive and they all connect fine to the network. Dragging files throughout windows works fine. When we try to attach a file from the network in the browser (as in a GMail message) or upload a file with FTP it disconnects us from the network and from the Internet.This only happens with 2 of the 4 computer.

I am having difficulty uploading files on the internet because the speeds are so slow. My download speed is 23.88 MBPS, bu upload is .3 mbps. This seems to be a recent problem. The other computers on the network get upload speeds of 5mbps and do not have any problem, so I think there is some problem unique to this computer, and not a network problem. I can't back up my files because the speed is too slow.

I have an HP Pavilion dv7 laptop running Windows 7 (64bit) SP1. Recently, my computer was attacked by some really nasty malicious software. Nasty enough that it not only got past my security software, it permanently disabled it.I was still unable to repair/replace my security software. Finally, the support tech just gave up on me, and I ended up utilizing the restore feature provided by HP to restore my laptop, supposedly to factory condition. After the restore, everything works great except for my mapped drive.

I'm having a problem with my wireless internet connection. Just recently my roommates and I got cable internet and a wireless router for the house. Since connecting to the wireless router, it keeps on disconnecting me and then reconnecting once every 2 minutes about. The disconnection last for only 10 seconds but is very annoying and disrupts everything I'm doing on the internet. What is going on and how can I fix it?

My wireless internet has been acting a bit weird lately. I use a linksys Dual band wireless-N USB adaptor (WUSB600N) to connect to my router, a 2wire 1000sw. I am on windows 7. Recently, the internet has been dropping and reconnecting the connection weirdly; it is apparent in Portal 2 Co-op mode; it says the connection has been lost to the server, and then within 4 seconds, re-joins the server. During that time, the little network icon (the 4 bars in the task bar) says "Identifying."

About a week and a half ago my n5050 began disconnecting from the internet and reconnecting about 20 seconds later. This happens pretty frequently, about once a minute or so. It makes doing anything over wifi almost impossible. Plugging in an ethernet cable (directly from modem or from wireless router) keeps the internet connected. My wife's laptop, coincidentally also a Dell, doesn't have this problem. Neither do mine or my wife's iPhones or my kids' Nintendo DSs. I'm totally lost. I've tried uninstalling the adapter, updating it, updating the firmware on the router, changing the power options on the wireless adapter, changing wireless channels, uninstalled and completely removed AVG 2013, tried a clean boot, and more. I'm getting real close to scrapping this computer and going with another brand...
