Desktop Suddenly Cannot Connect
Jul 9, 2011
I'm stuck with their crappy wireless which has, up until now, worked perfectly. Yesterday in the middle of browsing however, I ceased to be able to connect to any websites. I'm still connected to their network, but I just don't have internet access. My laptop connects flawlessly and I've contacted the front desk and there's no issues on their end, so it must be something with my desktop specifically. I've gone through pretty much every solution I've come across. I've reset winsock, flushed DNS, released/renewed IP, uninstalled/ reinstalled my wireless adapter's drivers, system restored in case a Windows update burned something, tried manually setting IP/DNS settings..None of it has worked. I'm about to buy a new adapter just to rule that out as well. [code]

I just recently got back from a 2 day vacation to find that my internet on my desktop is almost unusable. I can get onto some websites and load videos, but it takes hours. I use Skype quite a bit, and I play online games. It is literally impossible to do either without my internet disconnecting.I use a 2wire Router i3812V with AT&T U-Verse. Here are my specs:[CODE]

I have an HP Pavilion running Windows 7 that was working fine for about a year on a wireless router at home. I have 2 laptops and a Mac that are all running fine and can recognize the wireless signal but for some reason, the desktop PC suddenly won't recognize the wireless. I have tried a system restore, no good. I have tried to load a different Intel wireless network adapter and downloaded a driver from the laptop I have that is connected, but still no dice. I thought it was a radio hardware switch that accidently got turned off, but I can't find anything on the keyboard or tower that looks like it would turn it back on. Running out of leads.

My laptop was able to connect to this network in the place i am renting in.Then one fine day, it just stopped and gave me a Yellow triangle with Exclamation mark.Says that i have limited connectivity and unable to identify network.I have tried everything i could by the looks of it, other thangetting my hands on the router/modem thingi (it is not mine and belongs to the landlady+her son).I have even tried to connect using a usb wifi thngi(dlink) but still the same problem.I am able to connect to that same network via my iphone 4 and i am able to connect my laptop to the internet via that same iphone 4 using the iphone as a wifi hotspot(pdanet).So i use the phone to catch the wifi and broadcast to my laptop.I have a second laptop that can also connect to the wifi just fine.

A couple days ago my gateway nv53 running windows 7 suddenly shut down not too long after a virus was found, upon restarting the Internet is no longer connecting and saying it is connected with "limited access". My iPhone, Xbox, and other devices in my apartment still function normally and only my computer is not connecting.

I booted into Windows 7 today after not using it for a while, and I saw "some network drives were unavailable" in the corner of my screen. I disconnected the drives, and used map network drive to add a new one. It sees the server, but when I get to "Enter Network Password" every username/password combination results in "Logon failure: Unknown user name or bad password." There are only 2 user names and passwords that are used on my various computers in the house, and no combination of them worked. What's really strange is that the mac server is set for everyone to have read and write privileges.

Every time I connect it it will display "window cannot connect to (name of the network)" I don't know what happened. When I use my phone turning on WiFi, it was able to connect to that wireless network and get internet. I checked my network work adapter and it was up to date.I even reset the laptop to factory settings and it still display "window cannot connect to (name of the network)" when i try to connectDetails are the router is a Cisco linksys E1000 router which the network is W2psk-psk. I cannot change or reset the router setting because I am not the admin where i do not know the password to.[CODE]

My laptop simply decided to stop connecting to my wireless network.I'm at a loss as to why and what to do. All other devices in my house are getting a perfect signal from the network but my computer either can't find it, or only has 1 green bar and says it cannot connect. I've tried a system restore, I've tried to troubleshoot on my computer and can't figure it out. The weird thing is it is picking up other wireless signals fine (like my neighbors, ect) but just not my home one. Again, it was working one minute, then simply stopped working and hasn't been able to connect at all.

I was using the Internet fine lastnight switched on my acer laptop this morning and wasnt connected to the router. I tried connecting but it just fails. I'm still able to connect with my iPad and iPod. I tried uninstalling and reinstalling the network adapter however this fails to successfully install. I've searched for hours but can't find a solution. I'm also unable to reset the router etc because I live in china and the router is in a roommates room whose door is locked.

how to use a computer in the time before Windows, comfortable with using command prompt. Have fixed many issue over the years with old and crappy computers, through research. Not very familiar with wireless connections. Last week laptop started freezing on Windows load, going automatically to safe mode. If I restart the computer after loading in safe mode, Windows opens fine the second time. Have tried stopping all other programs from loading at start up. If I do a system restore, everything works fine for a few days, then starts freezing on Windows load again. When Window does load I get the application error: The application was unable to start correctly (0xc0150002) click ok to close. but can still log in to Windows. Also, When I plug my cell phone, via USB to computer it charges fine and can upload and download between the phone and laptop, however, if I connect a (USB) thumb drive I cannot open the folder, save to it or open from it. This is the issue I wish to fix first so I don't have to keep switching between my ancient and slow CPU and my Laptop trying to fix the above problem(s): Laptop recently stopped connecting to home WiFi (automatically or manually.) Ran troubleshooters, suggested I do a full power off the router and turn it back on. Did that still not connecting. Did a full power off of laptop and modem and router and restarted everything. Still doesn't work. Used manual Diagnostic tool and it fails the association test, suggests that I check the profile. I don't know much about wireless as I said, so I do not know what profile I need to check or where it is located.The laptop does connect sporadically to the internet at home, via WiFi, for a few minutes at a time on its own, according to the wireless network connections. During this time I see one of two messages in wireless network connections: Unidentified network or limited access. If I go into the network sharing centre it says I am connected to an unidentified public network and shows that this network is not connecting to the internet. If I use the manual diagnostic tool at this time it passes the association test but fails the ping test.
Distance from the router does not seem to make a difference.Often when it is disconnected I cannot even see my router in the list of available wireless network connections.I can connect wireless to the router from my phone and have had no problems even while the laptop is unable to connect and the old CPU I am currently on, which is a wired connection, has had no trouble either. Other things I tried:I've scanned for hardware changes in my network connections: none and tried updating my driver software: nothing to update all are enabled.

Dell Inspiron 1520 Windows XP SP 3?My Dell suddenly will not connect to access point / wireless router / DSL. Other computer in house connects fine. Computer is auto-updated by Windows, McAfee, Secunia, and frequently checked with System Mechanic, McAfee, Lavasoft, MalwareBytes. One of the auto updates may have been interrrupted.Says Wireless adapter "not present"...Does not recognize wireless in the area. Try to "repair" adapter, but message says adapter not present.I then use System Restore to 4 day earlier date and laptop connects immediately. I see a new symbol "Local Area connection on Actiontec m1000 has been added in the Network Connection window, and the Wireless Network Connection says it is connected to the correct network that has worked fine for several years.I have several Windows updates for the Malware Tool that install immediately if I reboot, but then I cannot connect to the network and have to use System Restore (which is taking longer and longer to restore...appx 1.5 hrs now).

I'm trying to connect to my home laptop from work. The home laptop is connected to DIR-655 router. I set up the internal and external ports to 3389 using both TCP and UDP protocols with the Application as "Remote Desktop". From my work PC I enter the external IP with :3389 and it fails to connect. I have also tried accessing internally which is failing too. All computers are running Windows 7 Home Premium Remote Access is enable on all.

My desktop computer was connected to the internet and working perfectly fine the night before, but when I woke up the next day, I had the red "X" on my network telling me that it's not connected.
Now since after that, my computer has not been able to connect. I really doubt that it has anything to do with my router, because my laptop and my brother's Xbox 360 can both get online just fine. But I don't understand why?

Anyways a little background info on my desktop. Runs on vista, I have At&t for internet and tv . Router is in my room so I have cord from router to back of my desktop.Well my desktop had been out of commission for a while but I had restored it and everything seemed cool. Everything except from then on it could never connect to the internet. Occasionally when I start it up it will show the globe and say connected and everything but as soon as I try to open up my browser(firefox) it will say it could not connect to webpage and will start saying on the connection local only. I really have no idea what to do about this, I have tried another ethernet cord and tried the windows updates when allowed and nothing has work

I've got a desktop computer using Windows 7 that wont connect to the internet but my laptop works.
I've tried resetting the router like umpteen times and the desktop reads the local network but wont connect.Changed ethernet cable twice. I do get the light at the connection so I assume thats fine.

I recently build a custom desktop and it wont connect to the internet. Ive had it directly wired to the modem and it recognizes the network but says there is no internet access. It also says the ipv4 and ipv6 is not connected. The problem isnt the modem because when i wire it to my laptop my laptop automatically connects to the internet from it.this is my motherboard and i downloaded all the drives that came with the CD. I will in the future connect my desktop with powerline networking but my router just broke so i wont be able to do that now.

I'm troubleshooting a desktop that will not connect to the internet, I've tried just about everything and still no luck. It is now connected directly to the modem and when I click on the red X between the network and the internet icons in network and sharing center to diagnose it says "Local Area Connection" doesn't have a valid ip configuration. But when I connect the same ethernet cable to my laptop I'm connected instantly. I've uninstalled/installed the network adapter, I tried cmds in the cmd prompt, I even did a system restore and still.........NOTHING!

My desktop is connected to the same wireless network as my laptop yet my laptop has connection while my desktop does not.The desktop might actually be connected directly do a router (says 'local area connection 2 connected' right now but still no connection).I checked other posts on other websites that say to post all this command-prompt information that i cant necessarily access because i do not know the administrator password.

We use Nortel VPN and the problem is that it's set so when you connect to it, you can only access company resources so no Internet. To mitigate that we use vmware and run Windows XP at the same time as our Windows 7 systems. I'd love to be able to use remote desktop though and connect to a system located elsewhere even another office computer and have that one on the VPN, but of course as soon you connect the remote desktop connection goes down with it.I'm just wondering if there's any ways around this. I'm assuming not, but I'm not sure how VPN fully works. Like if I had 2 network cards in the remote system, when I VPN in does it block connections from all network cards? Ideally I'd like to use something like Amazon Web Services since their Windows Server tier has the free option which is good, or will use another VPS type system running Windows Server.
