No Wired Connection - Desktop Lost All Connectivity
Jul 3, 2011
A few days ago my desktop (which is hardlined into a router) lost all connectivity. My wireless connections work fine and i have began basic troubleshooting; changing ethernet cables, taking router out of the mix, etc. Beginning to think the ethernet port on pc is going out (NIC card?). Funny thing is, it will come back intermitantly for 10 minute increments. power cycling does nothing.

I just connected a WRT190N v2 Wireless Router to my XPS 400. When my wife tried to connect our other desktop to the wireless network, everything seemed fine. I noticed that, when she wasn't actively browsing or using the network, her computer would lose connectivity, but regain it when a browser was opened. When I tried to use the XPS, I found that it had no connection. I regained connectivity after using the Windows Network Diagnostic tool, but neither computer seems to keep connectivity when left alone, at least for very long.

I have one HP Desktop that decided one day it doesnt want to connect to the internet.
On the network we have two HP desktops (wired), one Dell desktop (wired) and 2 dell laptops (wireless) all connected to a wireless D-Link DIR 655 router . All computers are running Windows XP. All are able to connect to the internet except one HP desktop (only recently).
I have tried connecting the HP desktop in question to the wireless router via a different cable and still no connectivity. I tried disabling and renabling the internet/repairing it to no avail. I've restarted the wireless router and modem. Nothing. I've even tried restarting the computer (who knows it's solved problems before).

I have a Linksys E2000 router that is connected to my cable modem. I have a desktop computer that is connected to the router via an ethernet cable, and two laptops in the house that connect wirelessly to the router to get internet access.
This morning, all devices were connected to the internet just fine. I stepped away for a few hours and during that time the desktop 'lost' its internet connection. I have tried re-booting the router and removing-reconnecting the ethernet cable but nothing is restoring the connection.
The fact that my wireless devices are connecting means my internet service is fine, right? So what is preventing the desktop from gaining a connection?

I've got a bit of a weird situation here as soon as I switch on my desktop pc my wireless connection is lost. This is only the desktop pc, I aso have a HTPC on wire, this one doesn't have any problems. If my wireless fails, my wired clients can still go on the internet. (see for detail the drawing at the bottom of this post).
The other weird thing is as soon as I set my wireless to WPA-TKIP there are no problems, but my wireless is set to WPA-AES due to the wireless N standard.
I also noticed as soon as my wireless drops out the router starts changing channels.
Part of my network is DHCP (in the range of 192.168.0.100 - 192.168.0.199) the other part has fixed adresses (192.168.0.251, 192.168.0.253, 192.168.0.254)
What i've tried thusfar
- other firmware
- replaced cables
- rebooting/restarting router
- setting up from factory defaults

I have a laptop running win xp. It was running fine this morning. I then brought it to a Honda dealer. The problem started there ...At first, I got a strong wi-fi signal but not network connection. I tried to repair (by right clicking on wireless network icon on the lower-right corner). The first time it seemed trying to do something but nothing worked. The 2nd time when I tried to run repair, the process hang and the machine could not be rebooted or shut off. I have to hold the power key for a few seconds to turn it off.Now, I am at home using another computer to post this message, which indicates my home lan and my router are working fine. But my laptop still has no connections - neither wired or wireless

After a brand new Router/Modem combo., there is NO local/wired connection with XP, although other PCs has a good connection with strong signal.
Is it because a spectific folder needed for wired/local connection got lost, .... or Networking card inside got defective?

I am using InnoMedia MTA6328-1Be2S from Reliance and D-link DIR-600 for sharing internet connection. I have a strange problem here after using internet for sometime..I will not be able to use internet unless I shut down and restart both Innomedia and D-link.I tried changing configurations in D-link but with no luck. I lost the connection no matter I am using wireless or wired mode.I do not know how to login to InnoMedia MTA6328-1Be2S as well.

I found out my onboard ethernet port was fried, so i went out an bought a RTL8139D ethernet PCI adapter. I fitted the adapter and plugged my cable in. It said Limited or no connectivity. After hours and hours of googling I tried everything. I changed the protocols, created static Ip's went into cmd and reset winsock catalogs, release/renew etc. The cable I am using worked previously in my room and it still works. (I took a laptop up to my room and plugged in the cable and had internet connection). So... I took my PC downstairs and used a different cable. This successfully connected me to the internet. That Rules out that my new ethernet card is the problem. MY cable also allows others to connect to the internet. Windows 7 64X Ultimate edition.

I'm a college student residing in the dorms a I did last year and over the summer. In both cases i had to move to different housing and internet connection went without a hitch. However i'm now at my new place, and i cant seem to get my desktop computer to connect to the internet. After 8 different campus tech crews came through, they've determined that the connection issue is not caused on their end. The issue as far as i can tell is not caused by the cable either because i got internet access when i bridged the connection using my laptop's wireless connection. I have also used the cable to connect to the internet on my laptop. However, when i try to connect on my desktop it says that that ethernet cable is not connected. No link light comes on, and the connection is not recognized at all.

Recently I've been trying to switch to a wired connection. The cord and the port works because I tested and the connection works fine with my laptop. But my desktop won't connect. The light where the cord plugs in lights up but my desktop does not detect it.

I have a HP desktop Pavilion p6531 p-b (Windows 7) that is hardwired to a Linksys 2500 Router. Internet worked fine until this morning where it can't connect at all. It can pick up the Wireless connection from the router but I can't get it to go online even wirelessly (although I am not sure if I'm doing that part right). I called my ISP and they reset the modem, etc as well as bypassing the router and we still cannot connect to the web. We looked at the Network Center and made sure that in the Local Area Connection, the Internet Protocol Version properties all have "Obtain address" and "Obtain DNS server" automatically checked. At that point their tech support was stumped.

Lost my internet connection to my Dell XPS 435t/9000 running Win7 (64) yesterday. Unable to restore. No know configuration changes other than the regular weekly window update. My service provider is Verizon FIOS and all there stuff checks out. My iMAC and Dell Laptop connect fine through the same devices (router/modem/switch).
The xps shows no hardware faults and all the wired connections are intact. Unable to ping router. Network Sharing interface shows good connections to switch and router by a bad connection between router and internet.
Ran WIN7 network troubleshooter and it just told me to contact ISP.Rebooted machine several times but no joy.

I recent bought an Asus G74SX-A1. While the machine runs like an absolute dream, it does seem to have a networking problem that I have been attempting to address for about a week. In my college dorm there is an ethernet port that carries an active internet connection. When my laptop is plugged into the port via ethernet, I receive no connection (well mostly no connection, every now and then I will connect for a split second allowing me to load my homepage, Google). This problem also exists on my dorm's WiFi. My LAN card is a RealTek BGE Family Controller (PCIe)
However, on my netbook (an Asus 1000HE, which I am typing this post on) everything is fine. I am quick to blame the retailer who sold me the G74SX seeing as they replaced the stock WiFi card with a Bigfoot Killer 1102 card, and my first assumption is that something was not installed properly during my laptop's assembly or that I simply messed up a driver update. I became quite frustrated with the whole situation and in order to find a quick solution I formatted the laptop back to factory defaults.
Something magical happened.For about a day and a half, my LAN card worked. I packed up my gear this weekend and headed back home, and at my parents' house my WiFi card worked wonderfully.I thought my networking woes were behind me, but this was not the case. When I returned to my dorm this afternoon, my LAN and WiFi cards began experiencing the same problems they experienced before the reformat. A third variable of some interest is that I brought my wireless router back to my dorm in order to utilize a less-crowded private WiFi spot and discovered that it worked fine and I was able to connect to the internet on my iPad using my router. This evening, however, my router decided to stop carrying an internet connection as well. I can connect to the router itself, but I cannot receive an internet connection, even on the netbook.
I have tried uninstalling/updating drivers for both the Bigfoot card and the RealTek card to no avail. My best hypothesis is that the problem lies in some setting that both the G74SX and the D-Link DIR-655 have in common, seeing as they are the only wired components that aren't receiving a connection.
Equipment: D-Link DIR-655, Asus G74SX, Asus EeePC 1000HE

I recently upgraded to a new computer, it runs beautifully as expected however I encounter this problem with gaming. Whenever I hop in a game such as Dead Island, Arma 2 : CO (Day Z), Stalker : CoP, even Skyrim ( with SKSE, standard it ran okay. ) my connection will drop for my entire local network. I can still connect to my router, and it shows that I disconnect and reconnect with a new IP, from the logs it seems to be unprovoked. A few games will operate normally, however with Stalker, I play completely offline, and my connection still drops. It's not an instant disconnect, and it generally varies in time. However, when I'm not gaming, I get a steady connection with no issues, I get advertised speeds and can stream videos, and download perfectly fine. I've tried a USB wireless adapter to cross my motherboard off the list, and it encountered the same issue. But this problem just started occurring when I got the new computer.

Internet connection was lost after a recent program download that some had flagged with suspcious nature. A static IP address had been established through a Netgear (WNDR3300) router with an antiquated Netopia modem. Static address/Defaut gateway has always began as: 192.168..... After connection loss, reset (or so I think) IPv4 properties back to: Obtain IP address automatically and have received an IP address as: 169.254.172.83. Also have not been able to access router or modem settings/configurations page(s).

I have a L2L IPSEC tunnel between a set of failover pair of two ASA5510's and a single ASA5505. Over time they will loose connectivity through the tunnel. The tunnel itself stays up, but cannot pass any traffic.When looking at the tunnel I always see this on the set of 5510's (marked in bold @ IPSEC ID 3)?

In my 3750 stack switch there are more than 10 L3 vlans currently in use.In that only one vlan for example vlan 11 (we given up link directly to the nodes connected to that ports which is in vlan 11)losing connectivity for sometime and again connectivity restored.Except Vlan 11 all other vlans are working fine. When we troubleshooted the issue some of the ip's able to ping and some not able to ping. checked the interface status of that ports (no crc and input errors) and port is in up status only.we also checked cpu utlilisation ,device uptime, all are no issues found. am sharing my sw basic config and one interface status at the time of issue.But only one port learning more than 50 Mac-Addresses dynamically.and am learning mac address violation in another port which is port security and storm control enabled on that port..Its seems to be any attack or something else????

My mother's computer periodically loses internet connectivity. This happens regardless of the browser (IE or Firefox). She must restart her computer to get access again. This happens regardless of her internet connection. She uses verizon at her home and accesses through my wireless router when visiting. This also happens if she is on a public access network such as a hospital

I am working on my Mom's computer so I will need to download any files to a flashdrive to transfer. Her Compaq CQ5110Y Vista 32/bit pk 1 has lost it's network. I also just discovered a Trojan Horse Dropper in the BSTQBackA file. Did I mention I know nothing about this tech stuff? Norton states some files cannot be healed?

Region : Sweden
Model : TL-MR3420
Hardware Version : V1
Firmware Version : TL-MR3420_V1_121123
ISP : Tre
I have owned the TL-MR3420 for about six months and never had any problems with it, 3G connection stable enough and wifi and LAN worked properly without any drops.About one week ago I started experiencing problems. Both wifi and LAN gets disabled and I need to pull the plug and do a hard reset to correct the issue. This only happens after some heavy use, many devices is connected to Wifi, streaming files over the WIfi and so on. A scenario may be the following; there are six devices back home using all using wifi. All of them are not connected at the same time, but four may be; usually three computers and one tablet. The HTPC may do some heavy videostreaming from another computer. When the streaming is over, some devices are shut down then I may lose the WIFI and LAN ability of the router.
I have tried connecting with cable after wifi were lost but no IP address where given to it and connection where refused. This means I have no possibility to access the log file in the router, and after reboot the log file is reset. Router settings is pretty much default.Is my device broken or is there any setting I may tweak with?I have updated to latest firmware and tried to change channel without success.

My E3000 has been running for months without a hitch. Last night, it lost connectivity on the 2.4 GHz. I can connect on my laptop (Dell, XP) on the wireless 5 Ghz only. Wired connections (2 PCs and one video device) connect fine. All wireless equipment (laptops and LG DVD device needing 2.4 GHz) see the 2.4 GHz with good signal but will not connect. Of course, I rechecked name and passwords.
I tried the MSR restart and reboot several times, including turning things off overnight. Checked to be sure settings were not corrupted in setup.E3000 running firmware 1.0.04.

My daughters Studio 17 laptop lost all internet connectivity. Wired and Wireless. I have been searching all kinds of threads but don't seem to find a solution to this issue. I have done two systems recoveries to earlier dates when we know it was working to no avail. I have 3 other computers on this network and none are experiencing any issues. I did just change from DSL to cable broadband, but the computer was fine until Monday night. Not sure what is going on. Does a system recovery will undo Windows updates? The most recent updates took place on 1/4/2012, which is about the time the problem showed up. I am going to uninstall those updates, 2 Security Update for Windows, and see what happens. Stand by. No good. It didn't work. I see a lot of people who are having the same problem here recently so something must have changed.

I have a new Linksys E3000, 2 wired disktops (1 windows 7, 1 windows vista), 2 wireless laptops (both windows Vista), whenever the computers power down into sleep mode and are woke up, I have lost my connections to the router and I am forced to restart the computer. I've been told by one person that this is a problem with vista and windows 7, but wouldn't that have been a problem with my old router also?

I recently set up a wrt54g router that I got used from a friend. I pressed the 'reset' button on the back, configured it for my computer according to the instructions on the website, and everything worked fine for a couple of days. Then I lost connectivity, tried powercycling my modem, but had to reset and reconfigure the router again. Worked fine again for a couple of days, then the problem repeated itself, so I reset and reconfigured again.

Noticed this AM that a new firmware was releaesed to my EA6500!! Very surprised to find it Monday AM. I went ahead & updated my firmware but lost connectivity to my Comcast cable modem. I was leaving for work so I had to pull the router & revert back to my original Linksys router.zBig storm heading my way, figured the wifw ywould need internet to track Hurricane Sandy. Any others have a new firmware waiting for install this AM? Keeping my fingers corossed on this firmware upgrade. I'm hoping it solves the device map issue.

I updated the fimware on my WRT160N v3 and followed it up with a reset of the router. I then restored the router settings that I had saved. All the settings appeared to be good, but none of my wireless devices would connect. I reneted the pass phrases (WPA2) but still nothing. Tried to change the passphrase, still no good. I then did a factory reset of the router from the setiings page and manually re-entered and save the settings, again nothing. All of my devices are able to "see" the network and the correct SSID.

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 an Acer Desktop Aspire AM3100 running Windows 7 Ultimate. I upgraded my memory. When I turned the PC back on I had lost my whole home network and cannot get internet acces back. I have checked my modem by direct connecting it to my laptop. I have checked my linksys box by doing the same. I can see the linksys on my laptop but cannot access the internet. On my desktop I get nothing?The home network and internet access all disappeared when I upgraded memory.
