Network Connection Stops Working When Computer Turned Off
Sep 4, 2011
I am having quite a large problem with my TalkTalk connection. Whenever i turn off my computer, internet access stops for the entire network, anyone who is conencted, however, local access is still possible.I am also having a problem with the wireless in my laptop also. Whereas every computer on my network is able to access the router wirelessly, my computer (the one that seems to chut down internet access) won't do that, i send packets, but none are received.

I have an EuroDOCSIS 3.0 cable modem from UPC Romania. It's a Cisco EPC3925, wireless modem.
My problem is that most of the time (like 80% of the time) when someone is starting or closing a PC that is connected using a wire, the whole internet crashes (wired PCs get a ! sign and the internet stops working and wireless PCs are getting disconnected completely from the network being unable to reconnect). This is solved by restarting the modem (unplugging/replugging it) or waiting for it to reconnect. I want to mention that during this process the modem lights show that everything is ok and nothing special happens.
First of all I called UPC technical support and the man there said that I should try to disable the firewall from the modem (which I had disabled already), if it won't work then to try to reset the modem to the factory settings (as I was thinking to do - because I configured the settings as I wished) and if this won't work then calling them back to change the modem.
I tried to reset to the factory settings and that didn't work at all after running tests over one week. After that I called UPC and they said that the modem is for sure the problem, they sent a technician (today) who also said that the modem is the problem. Ok ok, the technician replaced it and everything seemed to be good.
30 minutes ago my father started his PC and what should I see? Bam, internet crashing. 5 minutes ago i closed as well my PC and what should I see? The internet crashing again.

I pay for a 50mb service and reguarly check the download speed I was getting. I would always get between 45-50mb. However I went on holiday for a few days, and so I turned all the plugs off at the wall(something I never do) and since I got home im getting speed of around 20-25mb. I called the engineer out but he wasnt able to do anything because when he connected it to his laptop, he was getting speeds of 47mb. He said he didnt know why i was getting such a slow speed through my desktop, just said it must have something to do with my computer.

I have a TL-WR740N router, and the problem is that when I shut down my Desktop PC wherein the router is connected, the devices that are connected via Wi-fi can't connect to the internet anymore even though the router is still ON.

I recently bought a new laptop (Asus U47VC) and i am having internet connection issues. When I am at my mother's place or at school, I have no problem connecting to the internet wirelessly. However, at my father's place, my internet stops working every couple hours and will be unable to connect to the network until i reset the router and modem. Once the reset is complete, I am good for another couple hours. All the other devices ( laptops, iphones, etc.) do not have this problem and the connection is never an issue. I have read that this could possibly be a problem regarding IP addresses but I do not quite understand how to fix this.

I have a windows vista pc networked to a second pc. I have wirelessly networked internet to 2 laptops. I have an actiontec wireless modem by verizon. All of a sudden my host pc started randomly losing internet connection, but the wireless laptops still have a signal. It seems like the host sometimes can't "see" the modem.Here are my settings while the internet is functioning.Microsoft Windows [Version 6.0.6001]Copyright (c) 2006 Microsoft Corporation.

I bought this router and ever since my internet connection will drop out for 5 minutes at a time then come back in. This happens on both wifi and the wired connection. The weird part about it is that if there is a program that maintains a constant connection, e.g. xbox live or an online MMO, they don't lose connection when every other device or even tabs within the same browser all lose connection.
BTW It's the REV_B with the 2.07 firmware.

My wireless connection for 2,4 GHz stopped working correctly. Here's the set up:
I have an E4200 Linksys router. Furthermore I have a desktop running on Windows7 connected to the router with a wire. No problem there. I can connect to the Intenet via the E4200 and a modem.Then I have a notebook also running on Windows7. Until yesterday it was wireless (2,4 GHz) connected to the router and to the Internet, but now I can see the router on the networklist (so there is connection), but it will not make contact to the Internet. If I hook up the notebook with a line to the router it works OK.Then I have an iPad which makes a wireless connection to the Internet (via the router) for the 5 GHz option, but it does not make a connection with the 2,4 GHz option anymore (before yesterday this worked well). I did not change any settings on the Linksys or other network options, Can an update from McAfee make a difference (only for 2,4 GHz?).

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..).

My computer runs bit torrent almost all the time, sometimes when I start Firefox the home page google never loads and neither do any other web pages yet bit torrent is still working as if nothing has changed. If I start a download in Firefox come back to the pc a few hours later Google doesn't load but the Firefox download still continues.What causes this is it DNS ?

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.

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?

We have 3 pcs connected to the router via cable and 2 more pcs connected through wireless. Everything works great. But when I try to connect (want to connect 2 more laptops via wireless) either one of the two laptops, the whole network stops working immediately. 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.

If I have anything else connected to the network (anything being my Xbox 360, or my smartphone) and I turn on/wake up my computer, the entire network crashes and I have to power cycle the router and modem in order to get it to work again. What would even cause this? I often forget to turn off the wifi on my smartphone before I turn on the computer, which results in a lot of very tedious power cycling. It's also frustrating if I'm playing some vidya on the 360 and my wife gets on the computer, resulting in me getting kicked off and her unable to even do what she wanted to do in the first place.
The stranger part is that if I have my computer already on, and I turn on the 360/smartphone, it works fine. So there's something going wrong in the process of my computer connecting to the network, I guess. I have set a static IP, and I also made sure to turn off the energy saving feature of my wifi card, but neither of those things solved the problem.

My NIC card started flashing last night. The computer was turn off, and the network cable to the cable modem was unplugged. Also, I installed some free software that day and wonder if there is a connection.

Upon turning on the computer, the wireless will not connect. It seems to not recognize the configuration of the wireless. I have to go in and put in the key every time... and then there are times that it says "limited or no connectivity". We just had a new router/modem installed in our network just yesterday. This router/modem is in conjunction with cable tv difficulties we were having.

I have Comcast cable going through a Netgear wireless router (WNR1000V2) with 2 PC's connected to it. (both desktops are wired directly to the router)When ever my computer is on and I game, I get a steady low latency ping, usually <50ms.But when my roommate turns on his PC, every 5-6 seconds or so I get a surge upto ~250ms.I disconnected the ethernet cable from his PC while I was gaming and the surging stopped and I had a very smooth connection. But as soon as I plugged it back up I started getting horrible ping. This leads me to believe that some program on his PC is interrupting the internet latency.
I am completely lost on how to track down what is sapping my internet. His PC is not running any bit torrent clients or P2P programs at all.We both are on a 2 month old copy of win7 x64.Are there any programs that I can use that would tell me what is using the internet to the point of lagging the whole network?

there has been issues with this router, and I wonder if any of you have issues connecting to the 5ghz when you wake your pc from sleep longer than an hour. For some reason when I put my computer to sleep at night and wake it up in the morning, my computer will not connect to 5ghz. It will work fine with 2.4, both are set in auto, so I dont see any issues. I did try to put 5ghz to a manual setting; wpa2, 40 mhz, and channel 161. I still get the same results. I am doing something wrong or is the router's 5ghz faulty?Also when is the new firmware coming, I am getting sick of my Harddrive being awake 24/7, its killing the harddrives life span and wasting electricity. I should put this in another post, because they should really change the media server to Wild Media Server or Serviio it would be alot better.

I am having a trouble with my router, our modem is the one that is connected to a TV box and it comes with a wifi function(a modem with a wifi function). I am not sure how to set it up, so I connected it to E4200 which is located in another room using CAT6 flat cable and set it to "Bridge mode". But whenever I open the TV box, the wifi won't work, and when it's closed, it works. :s how weird is that. Are there any problems? The modem with wifi will always work either way I open/close the TV box, but the E4200 wifi will only work when I close the TV box. I asked my service provider about this and they tell me it's not their problem anymore.

my boss has a vostro 1500 laptop and is constantly losing internet connection. Before losing connection, a little blue world shows up in front of the computer picture in the lower right hand corner and then says *limited access available*, then he can not connect at all. If he disconnects and then reconnects it works for a short period of time and then the cycle begins again. Recently, i was told it was a new router, so we replaced the old router and still having these issues,

I have a PC with a Realtek onboard Ethernet controller, running Windows XP. It's connected to an Asus RT-n16 router loaded with TomatoUSB, via a Cat5e cable. When I set it up a month or two ago, I confirmed that I was getting a Gigabit connection to it--the little network connection icon in the Windows XP taskbar indicated "1.0 Gbps." All well and good. I just happened to check it today, and it now says "100Mbps." Nothing, as far as I know, has changed to the configuration. I went into the Device Manager, and saw that under the driver settings, in "Speed", it was set to "Auto-Negotiate." When I tried setting that to "1.0 Gbps" instead, the network connection icon in XP's taskbar once again indicated "1.0Gbps." As an experiment, I then changed it back to Auto-Negotiate, and once again the taskbar icon read "100Mbps."So I guess I have two questions. 1) Should I leave the driver setting on 1Gbps rather than Auto-Negotiate? (2) Why might the speed have switched from 1Gbps to 100Mbps over the past month if nothing's changed?

I have a Asus n55s. The wireless acts very funky. It sometimes disconnects and stops working. Sometimes, it will stop detecting any nearby wireless networks altogether. Then I have to enable and disable the wireless functionality until it starts seeing nearby wireless networks.

I've been having this problem with my laptop's wifi for a while now and it's been getting a little out of hand lately that I can't deal with it anymore. I asked some friends and they seem to have the same problem too but not nearly as often as I do. Every so often, my laptop's wifi just stops working so I turn it off and then turn it back on and it starts working again. My friend says it happens very rarely to him but for me just today it happened 2 times within 10 minutes

I'm having is that every few hours my TCP/IP protocol stops working. The modem lights remain normal but I can't connect to anything. The only thing that works on the internet is traceroutes at the command prompt which function normally. The solution is that I have to reboot and then everything returns to normal until a few hours later when it happens again. There are no error messages on any of my browsers. The page just goes white immediately. When I try to retrieve my email, I get a message about the TCP/IP isn't working.

On Windows XP, my integrated NIC stops working after hosting a server. The server starts fine, ports are forwarded, firewall is down, modem is fine, but when I receive a connection, it shows they have made a connection, but then they drop, as do I. I can't browse or ping anywhere. I have to physically disconnect, then reconnect the ethernet cable to the port, or restart the computer. Upon ipconfig, the adapter is set with the Windows default ip (169.x.x.x) and cannot be /release'd or /renew'd.
