No Network Access - Internet Connection Lost On Dell Computer
Jan 12, 2012
I have a hp compaq laptop and am able to use the wireless internet connection..however I also have a Dell Inspiron notebook, a few days ago I lost internet connection on the dell but the HP was still connected. I have contacted my internet provider and they say there are no connection problems and all is fine. They think the problem is on the dell unit. I have tried disabling and enabling the Lan and wireless network connection. The system recognizes the wireless router but wont connect to it why and what can I do.

I have 3 computers running Windows 7 Ultimate x64.
I connect them to a hub and set a workgroup name. Everything is working fine. All of them are able to see each other and access their shared drives.
However, once I unplug internet line (all computers still connect to the same hub), computer cannot see each other and cannot access shared drives anymore. Also, workgroup name is changed to 'Unidentified Network'.
What should I do to connect to a network without internet connection?

All of a sudden my Windows 7 (64) machine lost internet connectivity. Nothing new was installed; no changes were made. It just lost connection. My Vista machine still connects fine. I'm scratching my head over this one. I reset the router and tried Windows troubleshooting services to no avail.

My desktop has recently been upgraded to Windows 7 Ultimate from XP. I set up a home group at another location, then returned the desktop to my normal connection. The wireless card I used was a D-Link that is XP compatible only, and I found this out after attempting to install, then I checked on it later. I deleted the driver, and tried a Netgear WT111G USB wireless card. Install failed, and I went online to look for a compatible driver.
I downloaded a driver, installed it, and the wireless card was detected, but could not connect to the internet. Uninstalled the driver, and tried plugging into Ethernet, and cannot find my home connection. Can only get into network settings (home,work,public).
Has any one here heard about this problem after creating a homegroup? Trying to troubleshoot, but it's a specific problem I'm not familiar with as of yet.
The faulty drivers are no longer on the PC, but it's still unable to find a direct wired connection.

I had problems with my computer not connecting to the network sometimes after restarting my computer. That was usually fixed by simply unplugging and replugging into my outlet. I have a hard wire connection and my ethernet cable gets plugged into the wall and connects to the modem/router (whichever it is) from there. After I reset my computer this morning though, my computer has absolutely refused to connect to the network. I've tried resetting the router/modem and unplugging and replugging in my Ethernet cable. I noticed however in the network center it showed me connected to Network 8 (my standard home connection) for a few seconds but then it changes to unidentified public network and breaks connection to the Internet. Wireless is working fine and I'm infact typing all this on my iPhone 4.

ACER Eee PC running Win7 with all windows updates. The problem is the machine running Windows 7 Home Premium intermittently loses "internet access". Where the bars are full, but the ! shows and there is no connectivity. The other Win7 machine is set to automatically install updates and is running fine, although it seemed as though I was restoring it every week or so to get connectivity.Back to the point, the machine in question is Win7 and all available updates are installed.Bonjour service is "stopped" (but it runs fine on the other Win7 machine), TCP/IP was reset, Winsock is reset, registry/temp files cleaned via CCleaner. Zone Alarm Free and AVG are running, but they were running this morning, yesterday and a while ago when it lost connectivity again. One time I went to bed annoyed ready to set the %^&* thing on fire, but in the morning it was working fine!
I'm not exactly a N00B, but I'm dying for an explanation or a fix other than restoring every time "internet access" isn't available. Mind you, this house is full of nerds...Android phone, two iPhones, Lubuntu, Win7 Basic, Wii...all wireless and a wired Vonage that all works great.I was a member of That Computer Guy forums for a couple of years and learned a lot from the moderators and know how much work you guys do to give us this free service.

I have recently been having difficulties with connecting with my wireless connection. We have a in-home router that is connected to two computer's downstairs by cable. I however own a Acer, Windows 7 laptop that I mainly use upstairs and I get a Excellent signal strength.I have connected to my Home wireless connection before with no problem but recently the connection keeps coming up as ~Identifying... No Internet Access.Also when I have had connection to this network prior to this problem the connection is under Home. But when I try to connect to the same network it comes up as Public or just keeps Identifying. I have the connection set to Connect Automatically.Also the yellow triangle with the exclamation point almost always pops up immediately when I reboot my system or after I Disconnect and Connect the network again. I have tried Disabling and Enabling the network in the adapter settings and this does not work either. In the manage wireless networks tab, I have repeatedly deleted the connection and reentered the security password and again put it as automatically connect but it still comes up as Identifying. I have seen many people with this same problem and have tried many of the suggestions to no avail.It is rather bizarre because my connection will be in this Identifying state for a while and randomly connect properly and I have no idea what makes it go off and on so erratically. I just had it working again for a few days and it is again acting up.

Basically my ethernet capability flew out the window ranomly the other day. Wireless works perfectly however.. before ...the other day.... it has been working solidly for almost a year Im plugged into a router which is running off my cable modem, both sitting less than a foot away from me. Also hooked up to the router is another computer, and my xbox the xbox works but the other computer cant seem to get a local connection either.
at first i assumed they were having an ip conflict of some sort, but why now after all this time?
I have tried:
- ipconfig /release - /renew
- abolishing bonjour
- taking the other pc completely off the router/network
- updating drivers.....rolling back the updates
- different cables different ports
-plugging directly into the modem
- and asking nicely
im on my laptop, Dell studio also the first time i noticed this happen was directly after having powered down the modem and router.
below is the ipconfig

I used to be able to access the internet on this computer - on a small business server 2003 - on the Network Sharing center, it shows that I am connected to the network (doesn't matter if I'm on wireless or wired same issue) it shows an x on the display for internet. I checked the gateway and it is the same for the other computers that are on the internet. No problems anywhere else connecting to internet. I don't have any spyware/viruses. I can access files on the server and other pcs no problem - just won't let me on the internet. I read somewhere that it could possibly be SP1?

I had my HTPC up and running last night, watched a movie, turned it off and went to bed. When I woke up this morning I found that I couldn't get any sound while playing videos through my web browsers, thinking it might be a video card issue I first checked some of my movies, but they also wouldn't play with sound so I deleted my nvidia files and reinstalled them. No luck, on one restart I lost my internet connection with my router. If I look inside the Buffalo's settings, I can see my HTPC's IP address (after running ipconfig /all on the htpc) I did a system restore but that didn't work. I even went so far as to do a clean install of Windows on the HTPC, but that also didn't work. I keep getting the yellow triangle and the message "unknown network" The HTPC tells me to check my router, which I have restarted a number of times unplugging the cable modem and the Buffalo. Turn on the cable modem get it online, then plug in the Buffalo, but nothing works. I have tried switching ethernet cables, ports, but no luck.

The laptop can see the wireless networks (there are two wireless networks since it's a 2.4GHz/5GHz dual band router) and even connect to any of the two networks.It also gets an IP address from the DHCP server and the Internet connection starts working for a very short period (5-10 seconds). Then the connection is lost and though it occasionally returns, the computer is unable to access Internet most of the time. Apparently, it doesn't even get to the gateway. If I ping to the router's IP address there's no response, except for during the first few seconds after establishing the connection:[CODE]This behavior is absolutely consistent and can be observed each time one connects to the Linksys router from this laptop. Nothing I have tr includes: rebooting the laptop, rebooting the router, disabling one of the two wireless networks on the router, trying out various encryption settings (open, wep, wpa2), changing channels, disabling/enabling b/g/n modes, disabling firewall on the laptop, disabling ESET antivirus, reinstalling the wireless adapter driver, ... I could go on. I've been struggling with this for three nights and I'm getting desperate.
There are three other laptops (one Mac, two Windows PCs) connecting to the router without any problems. Strangely enough, the laptop only has this problem with the new Linksys router. It can connect to Internet via our old Airport Express wifi router without any problems. It can also connect to Internet via the Linksys router with an ethernet cable.One thing I have discovered is that rebooting the laptop in a safe mode with network enabled FIXES THE PROBLEM! However, when I boot back to the normal mode (even when disabling all startup items and all services, except for those needed for networking), the problem is back.

My iMac printed fine, then I realized my iMac could not see the laptop and the laptop could not see the iMac nor printer, but still has internet connection on the laptop. I now nothing about Windows 7.

So my son was in the middle of one of his blood bowl league games this evening and a popup asked him if he wanted to install a Windows 7 update. He's only 12 and inexperienced enough that he didn't just tell the system to wait a few hours until he could finish his game, so he told it to go ahead and instal. The result was his near-instant loss of internet (as well as his game, as he was timed out and his opponent got the win).
Even more serious, after the update was finished and his computer was restarted, he still cannot get an internet connection. I've tried rebooting, complete shutdown and then reboot, and asking the computer's internet tools to diagnose/fix the problem, all to no avail.
I read about running a system restore (restoring to an earlier version of windows), but when I tried I learned that that aspect of his system had been shut off.
I know there must be SOME way to fix this problem, but I can't think of what it might be. Even if the problem is due to the new Windows version, he has no way to download a fix for it because he has no internet connection.

I have two PCs cabled directly to a Netgear WNDR4500 router. This morning, my Windows 7 PC had no network connection when I turned it on. These computers don't get moved, I wasn't messing with the cables beforehand. Everything was fine yesterday.The Troubleshooter suggested I had a broken cable. I tried another cable, but it still would not work. I connected the Windows 7 machine to the same router connection my XP machine uses, but it still did not work.Device Manager reports the Network Adapter is working properly. The system tray network icon reports "Not connected/No connections are available." The Troubleshooter reports, "A network cable is not properly plugged in or may be broken." I tried disabling/enabling the Local Area Connection, but it still reports "Network cable unplugged." My gut feeling is that the Ethernet jack on the motherboard is physically broken. But it blows my mind that it would break for no reason.Could an automatic update of some sort disabled networking in a way that it only appears the cable is bad? Could the physical connection at the back of the machine spontaneously break? I suppose I could go buy a network card, which would be cheaper than replacing the motherboard. I'm gonna get cleaned up and head to the store now.

I'm in need of some serious help here. Working with a Dell Inspiron 1750 laptop that's running windows 7. The machine can not get full access to the Internet. It seems as if there is a software conflict, but I can't find what it is. It did display the BSOD a couple of times, but the screen was gone before I could see what the codes were. The system restore only has 2 days of restore points, neither did anything to help.Running the diagnostics produced the following codes. 0f00:0232, 968634624, 0x490, 0x8007042c, 2000-0151.All repair options suggest patches that require an Internet connection. Well...if the computer had an Internet connection I wouldn't be in such a state. Reminds me of the car repair manual that says to start the engine to preform a test when the problem is the engine won't start.Anyway, I'm at a loss. This isn't even my machine, it belongs to the sister in-law, which means I have no idea of what she may have done, if anything, to cause the problem.There's a lot of Apple software for the ipod, or itouch, whatever it is she uses.I can't access the recent update history, so I'm not sure if updates are a factor.It sure seems like a software issue, but what do I know? If I knew what I was doing...I surely wouldn't be here seeking help.One other thing, when the machine is first booting, a window of some sort appears just after the desktop appears. It only flashes for a split second before disappearing. Not long enough to tell what it is.Well that's all I have, I sure hope that someone has an idea. The computer isn't even 2 years old, so it'd a shame to have to throw it away. As far as programs goes, it has very little, and the 500GB HD isn't even 25% filled.
