Ethernet Connection Suddenly Not Working?
Mar 25, 2011
Ive been using my Sony Vaio laptop (windows 7) to connect to my uni halls internet connection by ethernet cable (and keysurf login) for months with no problems, now all of a sudden my ethernet cable is not being recognised. its not a problem with my connection or cable as other people's laptops work on it. and its not a problem with my hardware as my laptop works in other people's rooms. its just the combination of my laptop and my connection. My friend did something along the lines of resetting the IP address, but not really sure what he did. So i've done a full recovery of my computer.

---ipconfig /release, /renew in admin mode
---built-in Windows troubleshooting

My pc is windows xp an has service pack 3, the adaptor is realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC. I have 3 gig of memory and a very larg nvidia card. OK my pc has worked absolutely fine until this weekend when my sister came and her son was on my pc when everyone was in bed. He attempted to print of not less than 88!! pictures he had acquired from different sites but i had disconnected the printer so it didnt take place. When they left earlier today i switched on my pc and there was a virus alert so i ran a scan. These got put into the chest. I then attemtpted to close down the programmes that had come back up when i switched on and this is when it happened. The pc told me it was going to shut down and when it restarted i had not internet connection. I checked the modem and the ethernet light is out.

Connection Issue: Wireless
ISP: Comcast
Router Model: Netgear N300 Wireless Gigabit Router WNR3500U/WNR3500L

"Ethernet Connection has stopped working".Its stopped working again and I've run the Network Test and the results are in the file REG.txt attached. I can connect to the internet via wireless OK but I had wireless turned off to run this test.I've proven the ethernet cable OK by connecting another pc to it which works OK.

The other night we had a thunderstorm. It kicked me off the internet. Now, I can connect directly to my computer to my laptop (wired), but when I try and establish the connection between the Cable Modem and the Router...it will show a connection between my PC and my netgear WND3400, but not between the router and the cable modem. Also, the ethernet port on router does not light up when connected to modem.

I have an ASUS X58C laptop which has been working OK to the internet via the ethernet cable but it has stopped working.I used the laptop via the wireless connection to access the internet while away from home and on my return I can not connect via the ethernet but I can connect OK via wireless. The results with the wireless enabled are :
C:>ipconfig
Windows IP Configuration
Ethernet adapter Local Area Connection* 13:
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
[code]....
I can see that the ethernet adapter(s) are shown as media disconnected but I don't understand how to make them connected. I also don't understand why there are two ethernet adapters or what the Tunnel Adapters are.Before I did the ipconfig command I went into Control Panel/Device Manager/Network Adapters/SiS Ethernet Controller, right clicked and selected the Update Driver Software which searched the internet for a driver and installed it.

I've had the WRT400N for about a year and a half now and just last night it stopped sending out data when connected to my cable modem. I've tried connecting the modem directly to my Mac and it works just fine (that's how I'm sending this message now). But when the modem is connected to the router, I get no data. It connects to both the 5 Ghz and 2.4 Ghz networks, but it refuses to send data through the pipe. I've tried power cycling both the modem and the router to no avail.

TWC / Road Runner modem
dir-655 - Hardware Version: B1
Firmware Version: 2.00NA
dap-1522
windows xp
xbox 360
powerphone voip adapter
Here is my setup:
TWC / RR cable modem to 655
655 port to xp machine
655 port to voip adapter
655 wireless to 1522
1522 port to xbox 360
I am no guru but managed to get all this working about 6 months ago. Other than some TWC outages it has been fine.Couple days back the XP stopped seeing the net. It could still see the LAN. The voip adapter and 1522 / xbox 360 still work fine.Here is what I have tried:
Plugged XP in 1522, worked fine.
Plugged XP directly into cable modem, worked fine.
Plugged XP into port the voip is working on, did not work.
Tried other 3 ports on 655, did not work.
Since the XP machine works with the 1522 and cable modem I am assuming the XP machine is not the problem.Since the voip adapter works on the 655 ports I am assuming the ports are not the problem.

I cannot utilize my Ethernet connection when my Dell Latitude D630 is connected to a docking station. I have tried this on two different docking stations. I also have another Dell laptop that I have used in the one of the same docking stations and the ethernet connection is fine. I'm looking for assistance to troubleshoot this (even just determining if I can replace the connector and how I determine what type I need)

Windows 7 64bit
I turned on my computer one day and it gave me a error saying the card was not inserted. I powered the computer off/on a couple times, while trying different things, and it suddenly worked. The next day, it had the same issue again.
I tried reinstalling the card but it still had the same issue. I bought a new Netgear WN311B network card, same issue.
I plugged in a borrowed Linksys card, worked like a charm.
One thing I noticed was when I reinstalled the netgear card, it was numbered at the end of the in the device manager; Netgear #1, netgear #2, etc.. everytime I reinstalled it, the number would go up.

I'm having problems with the wireless button after I took my laptop apart to clean. The wireless button won't switch on at all and doesn't light up. When I press fn f8 nothing happens. I'm not sure what I've done. The wires are correctly in place as far as I can tell. I've tried the following things:Uninstalling the adapter in device manager and rebooting /Checked adapter is listed as working properly /Do a system restore /Check BIOS

My usb devices- whenever I plug my Belkin usb internet adapter in I get an error noise (3 beeps) and the device does not power on. I tried another one (Cisco) from a different PC and got the same error. Tried this on all the ports and updated the drivers. All other USB devices work fine, tethering my phone to get internet for now. Had been using the device without problems for months until getting the error. The error started occurring when I unplugged it and plugged it back in. Using Windows 7 x64 on an HP Pavilion.

called my internet company yesterday with a problem that my internet was not working.. so we went through some steps and basically he had me remove the wireless cord from the router put it into my computer (at the time it wasn't working via that either) and reset my ip, it started working after that and he just said I must've gotten a faulty ip. Now it still won't get internet from my router, we all have laptops in the house so wifi is essential. The internet light on the router still blinks green.[CODE]

I have a Dlink Dir-615 router and a Motorola SB6120 Modem. For some reason the router suddenly says it's receiving internet access from the modem. It has worked for several months beforehand. I tried another Dlink modem and got the same results. I have my computer hooked directly to the modem hence the ability to make this post.

I have a Netgear N300 wireless router. My laptop is Sonay Viao, running Windows 7.
This morning my internet was unreliable, and dropping every minute or so. Trying to trouble shoot, I switched the router off then on again. Now I have no wireless signal between my laptop and router. The router doesn't seem to be recognising the security password. I have not changed the password - this is still the original password for the router. Other devices are still talking wirelessly to the router.

I have had a setup in which my four DCS-930Ls transfer picture every 15 minutes over a Dovado-router connected to a mobile broadband modem. This has worked perfectly until this last night. No pictures are transferred and upon using the test FTP function the status page just says "Testing ...." forever. I've also tested e-mailing picture without success.

Up until about midnight tonight, my router, which has been plugged in to my cable modem, has been working fine for years, both wired and wirelessly. Suddenly, however, I went to log on to my desktop PC (wired connection; Windows 7), and I had no network connection. ipconfig indicated "media disconnected." My cable-based phone service (VOIP) is still working fine at this time.
First attempt - unplug router, wait 15 seconds, plug it back in. Still no good, though my network sharing center indicated that the network connection was appearing/disappearing every few seconds, never actually getting "internet" connectivity.
Second attempt - attempted to use a WIFI-based device (iPad), which could not see my home network by name at all.
Third attempt - reset both the cable modem and the router, bringing the cable modem up FIRST. Same results as the first attempt.
Fourth attempt - plug the wired PC directly into the cable modem - this worked fine and is how I am submitting this post as I type. So the cable modem is working properly.
Fifth attempt - look up the information on how to reset the router to factory defaults. Used a paperclip to depress the reset button for 10- and on a subsequent attempt, 30-seconds (no obvious "reset" blink pattern was observed). Plug PC back in to router. PC would not obtain any DHCP-based IP address and the network sharing center was still behaving as in the first attempt.
Sixth attempt - disconnect the cable modem uplink and see if I could get the local network functioning. Now I noticed that the LED patterns on the router were behaving as:
- Power and my PC's slot number lit
- All lights lit
- All lights off
- Power and my PC's slot number lit
- etc

A few days ago, my Linksys E3200 router stopped working suddenly for no reason. The SSID was still broadcasted for a few days, but no internet connection. Today the SSID does not broadcast at all and I seemingly have no access to it.I tried power cycling it.I tried reconfiguring it via the CD included in the box.I tried solving it with the wireless tools in Windows.

Region : Others
Model : TL-WR741ND
Hardware Version : Not Clear
Firmware Version :
ISP :
after year and a half of using TL-WR741 ND router, it suddenly stop working during the night. I have no problems with router before this happened (I think only one or two reset in 1 year and 6 months). System led light does not flash (some sytem error) and I can't access to 192.168.1.1 router setup site. I tried almost everything, unplug power, reset etc. for almost 100 times, reconnect the router with modem and PC in all posible ways, but still can't establish connection or even access to router's setup. Obviusly internet works fine?

My M20 Valet Plus stopped working suddenly last night. Now no power lights will come on and it now longer transmitts as a connection point . No apparent sign that it's alive. I've owned it troublefree for just over a year, but it is out of warranty. Any way to tell if there is hope of reviving it or if I'm just out of luck? Nothing happened at my end to cause this -- no power interruptions or other odd occurrences.

A couple days ago I noticed that my wireless internet connection on my iPhone would cut in and out, then stopped all together. I also had no connection on my mac which is wired to the WRT110. I bypassed the WRT110 and then I had a connection on my Mac meaning the WRT110 is the problem. I haven't changed or added anything lately that could've caused this....

I have the Linksys WRT54G And it was working fine for years! Then today my computer shut down and when I turned it back on there was a connection but my computer was not responding to any commands. The icon shows full connectivity excellent connection. When I try to go to a web page it shows Connection Error and cannot get to any web pages.I am able to get on other wireless connections from neighbors but not mine. I have gone thru different directions on here and I am not technical and don't understand what is being said. I try to go to 192.168.1.1 and it asks for a password which I don't have. I have tried everything such as password and admin and get nothing.I am able to get my ip address and default gateway address and don't know the next step.

I have a dell studio 1558 laptop and it's got this Bluetooth problem. I use BT to connect to Internet through my phone as a modem. But sometimes it suddenly stops working and the BT icon vanishes from the taskbar. Every attempt to restart it by Wireless switch, or by restarting BT service/process fails. (this does not happen with WiFi, or any other connection though). The only way I get back Bluetooth ON again is if I put the system to sleep, or I shut down and Turn On (Hibernate, Restart, Log off doesn't work). And this happens more frequently while multitasking than normal use.
I am using Windows 7 Home premium (service pack 0).I have the latest Bluetooth module installed, latest system BIOS installed as available in the dell website.

My Wireless network suddenly dropped out and now wont pick up any wireless devices.
When I go into Manage hardware it comes up saying that the Drivers are not installed for my network Controller. Searching does not find any to install and due to just relocating I cant find my original Disks that came with the laptop.
So I am reduced to sitting next to the router and being hard wired for the internet.

Right now I have my computer (iMac early 2012 summer purchase) plugged directly into the wall via ethernet cable for internet access. I have only begun doing this in the past week because my E1200 wireless router has stopped working properly. I have reinstalled and reset to factory settings and set up with Cisco Connect and setup manually over the past week troubleshooting every possible way I have ever known how. My internet, obviously, is working. And when I set up the wireless network it connects properly and obtains an IP address and the lights on the back of the unit light up correspondingly and correct. But I cannot connect to the internet via the router, wirelessly or plugged directly into it. Yet when I take the internet cable and plug it straight into my computer it works.Mainly just need to know if this can be fixed or if I need to go return this unit and get a replacement. The router was purchased two months ago and has not had any issues since I first set it up until a couple of weeks ago and my phone is using up all of my cellular data plan without being connected to my wi-fi...

I have a Studio 1557 laptop (purchased in late December 2009) that all of a sudden has lost wireless connection to the internet. Went to use it last night (Thursday) for normal use and no wireless connection at all. Before this issue, there were no problems connecting thru wireless at all...in fact used it Wednesday evening for work/surfing and no problems whatsoever. We are using a Linksys 160N router...have 2 other computers and 2 iPod Touches that are connecting just fine, absolutely no problems. It can connect thru a wired connection with no problems but nothing thru wireless...this is a fairly new router, about 10 days old, but haven't had any issues with it since set-up.
I didn't have much of a chance to do anything about this last night or this morning. I really don't want to bother calling Dell Support either.
Dell Studio 1557 Windows 7 64-bit, 8gb 1066Mhz, 320HD
