Packets Activity Stops But Still On The Network?

May 11, 2011

During the last month or so my internet connection keeps stalling and will not work until I repair the connection, however I am still connected to the network, I just can't send or receive packets. In particular when I am downloading things, it will stop after 2MB is downloaded or 300MB, it just random. After sending/receiving 7,000 packets or 700,00. This only happens to my computer with the wifi adapter. Prior to this I didn't have any issues for over two years. My phone and laptop still connect via wifi to the internet. And the xbox and blu ray player are connected via ethernet and have not had any problems. The log for my router states "deauthenticate reason 3", which I have found to mean "The access point went offline, deauthenticating the client". So, I figured that the issue could be the wifi adapter which I installed on the laptop and that too never had an issue. I used inSSIDer 2.0 to see the close by networks and changed channels to get away from the strongest ones. I tried switching to wireless n only instead of g and n, the problem still persists.

Then I figured the issue must be my computer and no malware, spyware, adware nor any virus was found. The same thing happened while in safe mode. I also tried the winsock fix to no avail, reinstalled the wifi adapter and made sure all firmware for the router and adapter were up to date as well as XP. I also tried with my firewall shutdown but I still loose the connection. So I then reluctantly did a clean install and even with the bare essentials it still stopped working. I also bought a 15ft USB extension to get a better signal but still, even though I have a good or excellent signal I still have problems. My latest thought was this was the only machine running firefox 4 so I went back to 3 and that didn't either. I checked my usage with my ISP and I am no where near the 250GB a month.

Linksys Wireless Router :: WRT400N Stops Routing Packets Randomly?

Aug 19, 2012

This happens intermittantly. This results in most connections (but not all) being dropped. I will be unable to connect to web servers. My connection to videogame servers will drop. However, AIM will stay connected. These were done simultaneously. The same thing happens with my Cisco AE1200 and a D-Link 802.11g adapter I have. Disconnecting my adapter and reconnecting it solves the problem. I have tried doing a factory reset on the router and installing the latest firmware. It seems to happen more frequently when I am doing a lot of throughput (downloading a game on Steam, for instance) but other times it will happen when all I am doing is playing a game (like Tribes Ascend) which uses very little data. This is extremely frustrating. When I pay more than $150 for a piece of networking equipment, I expect it to last more than 3 years.

Confusing Network Activity In Router Log

Aug 2, 2012

I was examining my router's logs the other day and I noticed a recurring entry stating that my PC's IP address was sending packets to the IP on port 80, and that the router was dropping them.Except for the fact that my home LAN uses the network EXCLUSIVELY. That is all it has ever used since this router was set up, and the only other networks we have EVER used are and So why, I wondered, is my PC repeatedly sending (presumably) HTTP traffic to a private IP that is not and never has been on my network?I wasn't worried about what these connections might be doing, since I figured they couldn't do anything, but I was kind of concerned about what was generating this traffic in the first place. So I downloaded Wireshark and ran a capture for 30 minutes. Upon completion, I filtered results to show only packets that contained the IP, as either the source or destination IP.Based on the router logs, I expected to see three packets with my PC's source IP address and a random source port sent to, port 80 every 10 minutes.And I did see that. These are TCP packets, and they appear to be completely empty. The only thing I noticed about them is that the SYN flag is set. I don't know what the significance of that is, if any, but that's what I noticed.

What I DIDN'T expect to see were the packets that had a source IP of These packets (also TCP) had the ACK and RST flags set, and they contained the text "Go away, we're not home." So not only are there packets being sent to an IP that cannot possibly exist within my network, but there are also packets coming FROM the impossible IP telling me to go away.All of that is scary enough on its own. But then I hopped on Google and did a search for the phrase "go away, we're not home," and almost every result was related to the decline of the Storm worm. After reading about Storm, I was more confused, not less. In its heyday, Storm used UDP traffic to communicate between peers, and my mystery traffic was TCP. Storm usually did not use well-known port numbers, such as 80, which I read was part of what made it so resilient. Not to mention that the most recent posts I could find regarding the Storm worm were dated 2010 and were about the possibility of a second Storm, and I didn't get this PC until May 2011. Plus, even if we ignore all of this and operate under the assumption that I have the Storm worm on my PC, that still doesn't explain the fact that the traffic from my computer is heading to a private IP that is NOT, I repeat, NOT being used on my network, my router says it's dropping this traffic, but my PC is still somehow receiving a response from an IP address that 1) isn't on the network and 2) can't be having any packets forwarded to it, since the router says it's dropping the traffic.So, operating under the worst-case scenario assumption, I used two different virus scanners (not simultaneously, of course) to do the deepest scans they are capable of doing. They both turned up completely clean. In fact, I've had AVG Free installed on my computer since I got it, and even if you look at my virus history you only see a few tracking cookies, a corrupted EXE from the Skype setup folder, and a Trojan dropper that I never even ran because I thought the file properties seemed fishy so I scanned it and promptly deleted it. So I now have to go back to operating under the assumption that I do NOT have the Storm worm, and I am back to the drawing board.

Keep Getting Blocked From Any Network Activity For 1 Minute?

Dec 25, 2011

I keep getting disconnected and blocked from using even LAN on my computer. This happens whenever I visit certain websites. For instance, I registered on a website that has me "kept signed in", and whenever I click to view that website, it partially loads and then for precisely 1 minute any network activity I try (like visiting my router configuration page, or clicking refresh or home to load google) will not go through. Only after that one minute is over with, I can resume browsing that website; however, if I leave it for too long, and then return, the same thing happens.

I've also noticed that if I sign out of that website and then visit it, that disconnect issue won't happen.But that isn't the case with other websites, as they require no accounts and are just pages with news and other stuff.I tried uninstalling and reinstalling my ethernet drivers, tried flushing dns, renewing ip, releasing and some other /cmd stuff that I found online.This also doesn't happen on any of the computers connected to my router (although, they are all using wireless - I am using cable to router).I'm on windows 7 x64, using a realtek ethernet card, Nod32 security suite (think it may be the settings on this thing? I set everything to super safe settings so I don't get any dumb viruses). Windows is updated (well, at least 3-4 months ago it was updated). I have no idea what is causing this, and why the precise 60 second interval until I regain access to the internet.I'm using Firefox, but this also happens on IE8 or 9 or whatever I have installed, so I don't think it's a browser issue.Things like facebook, youtube, pennyarcade and other junk work, but as soon as I go to google looking for, say, apartment rentals and open some pages, one of the links in the search results is bound to make my connection freeze.

Network Stops Working For 2 Mins When Laptop Joins Network?

Jan 27, 2013

We have a working home network with 4 pcs connected to the network. 3 via ethernet and 1 via wireless. Everything is working fine. Then we have 2 more laptops which are connecting via wireless. When either of those 2 laptops joins the network, the whole network stops working for a minute or 2. After that it starts working again for everybody (including those 2 laptops). However its super annoying when it does that all the time. (The laptop goes into sleep mode, when u turn it back on again the internet(and the whole network) stops working for awhile again..).

Not Receiving Enough Network Packets To Surf Web?

Apr 7, 2011

I have a Asus EEE PC 900 laptop running Windows XP Home. I DO NOT use a modem or router. I connect wireless to someones network (which of course i dont know who it is or how far it is from me) I connect to a Linksys unsecured network. I get good to very good (some times excellent connection from it) The name of my adapter is: Atheros AR5007EG wireless network adapter.Two days ago i was on the internet, and all of a sudden i Lost service ( usually when this happens i wait it out and it comes back)But it hasn't.So I'm checking through my settings and i noticed that im sending way more network packets than receiving. Last i checked it was around 40,000 sent and 5 received. So I wait and wait and wait and the most packets it would go up to is 90 while as sending is still in the thousands.It also says im successfully connected with good to very good connection status (but yet i cannot surf the web because i do not have enough network packets)

I tried different locations in my house (that didnt work)I uninstall and reinstalled my network adaptor (that didnt work)I turned off and on the wireless switch(that didn't work). Im wondering if this has something to do with my laptop or the other persons network? how can I increase the received network packets?

If I look at a site like wikipedia for example ,it has lots of text. If I capture those packets which made up that page using wireshark I cant find that text anywhere no matter what filter I use and even though I turn on ASCII. Is it because text is being rendered unreadable by some kind of compression?

Wifi Stops Working When Wired Network Plugged In?

Apr 22, 2012

On the basement level, and on level 2, I have in wall junction boxes where the Cat5E Ethernet wires come together. There are 6 lines that go from the level 2 box to 6 wall jacks on levels 2 and 3. There are also 6 lines that go from the basement box to 6 wall jacks in the basement and on level 1. There is also a Cat5E line running between the two boxes.I have wired all these plugs on both ends with T568B standard, and in each box they go into a patch panel. I have used a cable tester to test and make sure all these plugs are properly wired. I have also tested individual computers hardwired linked through to my router (without going through switches) and confirmed that they work that way, so I'm pretty sure I've wired it correctly.

At the second floor box, I have an AT&T 2Wire wifi router and modem, with AT&T Uverse service. I also have a monoprice Ethernet switch. In the basement box, I have another monoprice Ethernet switch (link to the type of switches I have is below). The switches are connected together via the Cat5E that runs between the boxes, and the second floor switch is connected to a free port on the back of the AT&T 2Wire Uverse wifi router.These wall plugs are not all currently used. In fact the problem I describe below occurs even if nothing is plugged into the wall plates.My problem is: when I hook up everything, so my wifi router is wired to the first switch, which is in turn wired to the 6 wall plugs upstairs as well as to the switch in the basement, and that basement switch is in turn wired to the 6 wall plates downstairs... at that point when I plug it in, my wifi stops working. Basically, whenever my router is plugged into this hard wired network, the wifi stops working. When I unplug the network, the wifi comes back (I usually reset it, not certain if it would come back just from waiting).

Interestingly, it doesn't necessarily stop working if most or all of the plugs are removed so the network is not connected (for example, if I just go through one plug instead of all of them)Does a network of wired Ethernet, even if not plugged into anything, cause some sort of a load or drain on the router that could make it stop working?

Network Stops Working When A Laptop Connected Wirelessly?

I have tried updating the drivers (they are up to date), removing the password from the router, gave the laptops static IPs (and all other pcs as well) with no results. As soon as one of the 2 laptops joins the network through wireless, it stops working for everybody. However if I connect them through the cable they work fine. One of the laptops uses win vista 64 bit, the other one win 7 64 bit. We have cisco RangePlus Wireless Router wrt110.

D-Link DIR-655 :: Router Stops Loading Webpages But Internal Network Still Works

Apr 27, 2011

I bought a DIR-655 for my parents after their old router died in a planned power outage. It's a rev. B1 model running the 2.00 firmware. It worked fine initially for a day or two with great wireless coverage, even in the previously low-signal spots in the house.Then the problems started. The router now has trouble loading any website. What you get is instead a page returned from the router saying something along the lines of "network unreachable, please check you internet settings" (I will go there today or tomorrow so I'll update the post with the specific error). Refreshing the page a few times sometimes makes it load, but extremely slow and then the same thing happens again a few moments later. The same thing happens on both wifi and through the router's LAN ports. If I connect a computer directly to the modem it works just fine, as it has always done before getting this router.I have disable QoS, NAT endpoint filtering and the firewall (SPI). I have also set the WAN port speed to 100Mbit/s in the router, to match what the modem is set to (also had issues with the default setting).

Linksys Wireless Router :: New Notebook PC Stops Entire Home Network On WRT110?

I just got a new notebook that has windows ultimate, and whenever i turn it on it knocks off all the other PCS on the network and the printer, including the one the router is wired to. I can only get it to pick up all 4 devices when i go into the Lynksys program and click change password. But then the program locks up and i have to shut it off manually.
I already reset the router four times trying to get it to pick up all the PCs but it never works. I'm ready to toss the router and get something else. Are there any settings I can change or reset before this router becomes garbage fodder?

Linksys Wireless Adapters :: WMP54G Stops Transmitting And Drops Off Network For Moment

Other info:  OS is Ubuntu 10.10, the machine is a Dell GX270.
