My connection keeps going out randomly and my computer is just having general bad connectivity. I know it is my computer because no other computers in the household are having this problem. I'm not really good with internet issues, but I've reset my router, restarted my computer, turned off firewall and antivirus. Those didn't work, and I did try using a ethernet cable but it didn't work any better.

I've recently installed Windows 7 Ultimate x64 Beta Build 7000 and I have Comodo Firewall 3.8.65951.477 64-Bit installed as my firewall. I get this problem that I can't solve at all .
When I click on " Run Diagnostics" I have this :
Indeed, I click "Yes" and this is what comes next :
PS : The Windows 7 Firewall is desactivated!
Anybody haves an idea on this problem, please ?

Recently had a virus infection and noticed that the windows firewall service is missing. When trying to reset to recommended settings by using control panel received error code 0x80070424. Cannot access other computers or shared files/folders on home network. Saw a previous post dated 12-17 that appears to be the same problem.

I am having a problem connecting to the internet in a public library where all other laptop users are connecting successfully. The curious part of the connectivity issue (to me, anyway) is that according to my computer I AM connected to the network. I have provided some screen caps of the issue (links below), and tried to run the Intel ProSet Wireless Tools diagnostic to troubleshoot the problem of connectivity. The test run by my computer indicated that my Ping Test failed Response: Default Gateway, DHCP server No Response.

This has been an issue since I upgraded to 7201. It isn't constant, and seems to be worse when I'm downloading large files, especially multiple files from one source (like an album in iTunes). It is fixed by release/renew (or just letting Diagnostics do that).
If I'm not using a lot of data (regular web browsing, working on a database online, etc), it seems perfectly fine. It is holding so far downloading one track at a time on iTunes, but if I do 2, it drops the connection.
I'm using the Home network config, router is working normally, and I can't recall this happening before 7201. I've reset the router, upgraded firmware, and it only happens on this PC. I've set WINS, tried all settings for TCP/IP 4 and 6, and using the other ethernet port on my motherboard.
More of an annoyance, really, but I can't figure it out and it is bugging the hell out of me.
EDIT: I can still get 1 mb/s on a single download, but trying 2, I get 600/400 for about 10-15 seconds until it disconnects.

I just recently purchased my Asus X53SV-MH71 laptop. For the first week I was able to connect to internet/wifi at my school perfectly fine. But now it keeps coming up as "Limited Connectivity." I've read some solutions over the web but none have seem to solved my problem. At this moment I am currently connected through an ethernet cable. If anyone can help me that would be great. I will provide the "ipconfig /all" cmd below.

I have a COMPAQ Presario CQ62-215DX Notebook. This laptop ran very well until the day its internet suddenly failed. When I try to connect to my WiFi connection, it says "The computer currently has limited connectivity to X". I tried troubleshooting, and it said there was a problem with my network adapter. I went to Control Panel > Hardware & Sound> Device Manager. From there, I disabled and enabled all of my adapters, but my internet was still non-functional. The problem isn't my router, because my husband and kids are connected perfectly. Is there a way to solve this issue, or do I have to get an expert to EDIT: I saw on a thread that I should try uninstalling and re-installing an updated network adapter, but how am I supposed to do that without internet?

I just recently ran in to an extremely frustrating problem with my laptop. I have an asus laptop, it's one of the gaming models. Just recently, it has shown that wireless connectivity is turned off whenever i boot up my computer. The thing is, though, that the manual switch to enable wireless connectivity is switched on. Whenever i attempt to switch it off, then back on, the graphic that pops up on your screen showing that wireless connectivity is disabled pops up even when i switch it on. It does the same exact thing when i use fn + f2, only the graphic saying that it's disabled pops up every time i press it, and wireless connectivity stays disabled no matter what. I have absolutely no idea what to do, this literally just happened out of no where when i booted up my computer yesterday.

I know there are few Limited connectivity threads but ive checked them, non of them have the answer im looking for so ill just tell you the story.I accidentily downloaded a malware/adware program called Antimalware Doctor, i tried going into safe mode and using multiple programs to delete it (Malware bytes, Spybot - Search and Destroy & AVG command line scanner) they apprently deleted it , i loaded my comp back to normal mode and there it was back in there corner >
i managed to get rid of the program by bringing up task manager and removing the process called "sorttm700" (thats what the antimalware doctor program was called in the toolbar when i hovered over it) then going to my computer and searching for sorttm700, i deleted all the folders with sorttm700 in them and rebooted and no more annoying ads to buy fake software however i still have limited connectivity (it became limited while the malware was on my computer and before i took any action to resolve it)i am trying to use the same network as the computer i am using now ot send this message, i never get connection problems with my laptop using this connection i have tried reseting my router and modem as well as uninstalling the driver and reinstalling and now there is a red cross with no options to connect to an access point, my wifi on my laptop is on before you ask?

just came over from XP Pro...had to get a 64-Bit machine; & went w/ an ASUS running Win7 Home...which I upgraded to Pro.I began to lose my internet connectivity, intermittently & noticed that, when it happened, the Network icon in the task bar showed TWO networks...(???).one labeled 'Network - No Internet Access'& the other labeled: 'Unidentified Network - No Internet Access'.Sometimes the problem would go away if i rebooted, but eventually it became a permanent dilemna.Verizon checked my modem...said it was fine, but sent me a new one anyway. Same problem continued. Took the PC back to Best But & swapped it for a new one...& it's been fine 'till this evening. It denied me access once.I rebooted; & got it back. Obviously, something is amis w/ Win 7 Pro in the way the network connection is set up.can't be two modems or two computers.I noticed it seems to happen right around the time that the OS goes looking for windows updates not in the same category.

My grandfather called me yesterday and said the other day - his Dell Desktop automatically downloaded Sp1 and Sp2 and once it restarted - he could no longer connect to the internet. *Note - he is connected via a cable to the router* The computer shows he's connected to the router but it cannot connect to the internet.
He tried to use a "restore point" prior to the update, but they were all gone. There are 2 other computers connected to the internet and neither have any issues - one is connected via a cable and the other wireless.
I checked the settings on the router and modem and don't see any "stand-out" type issues. I'm not sure what else to do or check?

I recently did a fresh install on my gf's computer as it was suddenly unable to establish an online connection. The error showed in the connection status as the small yellow warning icon at the top left of the connection status icon, not the big red X that appears when the machine isn't connected at all.
Here are the specs:
OS: Windows 7 Ultimate x64
Mobo: Gigabyte GA-X58A-UD3R Rev.1
CPU: Intel i7 950
RAM: 12GB Corsair Dominator GT 2000mhz
The system is also not overclocked.
After trying many things (reinstalling network drivers, flushing DNS, trying a different ethernet cable, restoring all network settings to default) I gave up and did a fresh installation.
After installation, I installed all the usual official drivers, then performed a Windows update, but only the important updates. The connection was back! I then decided to install some optional stability updates, and after reboot, the network problem was back.
I did a system restore to before I installed the optional updates, but the problem persists. I have no idea which optional update is causing this, or which one to remove first to avoid creating more errors.

I bought the Acer Aspire Netbook.I cannot access the internet from my home network for some reason. It recognizes the network and it says i'm connected to it, but wont let me access the internet. When I browse the network connection it says "Limited Connectivity" and depending on the way I diagnose the problem, it either says that im missing a wireless adapter or most commonly, that my IP address is not valid.
My computer was also running the internet very, very slow when I've connected at the school. I had a friend play around with it, and he actually downgraded some of the settings (or something), and it runs a lot better. But it still doesnt solve my home connection.I've browsed many forums and tried a couple things, but im mostly scared to try the in-depth solutions (mostly because im not THAT computer savvy, and since I just bought the computer im scared to remove certain things just in case).These are the specs:
- 1GB Memory
- 250 GB Hardrive
- Windows 7 Starter
- Model #: AO522-BZ499
- AMD c-50 Processor
I'm normally very good with computers, however im mostly a mac user and havent had a pc of my own in a long time.

Night before power went out twice, there was no network issues, everything was recognized normally and I had connection with windows explorer. However now it doesn't allow any regular connectivity (by that I mean I can use a third party program jftp and it finds/opens the samba shares correctly, but that doesn't have integration in a way that I need.I have tried several registry fixes from several forums, as well as rebooting each system, and the entire network several times and there has been no resolution.Using 'net use \192.168.1.2' nets a result of 'The specified network name is no longer available' however it can still successfully ping (and SSH) to the box.Windows explorer spews out 0x80004005 error unspecified and has turned up nothing useful after a couple hours of googling.The server -does- show on the network places but when clicked it says the path is not valid.

I recently installed Windows 7 (32-bit). I love everything about it except one major thing that seems to be a common problem, from the research I've done.Whenever the computer sleeps or goes in to standby mode, about 80% of the time when I come out of it, it loses the network connection. I will get one of two messages: "Local area connection doesn't have a valid IP address" or "Local area conncetion doesn't have a valid IP configuration." (It's usually the first message).I've Googled this several times and I've tried the fixes. I've tried searching for Bonjour (according to my Services list, it's disabled). I've tried setting the IPv6 off in the TCP/IP settings. I've tried changing the Wireless Adapter Setting's Power Save Mode to Maximum Performance. None of this has prevented this issue from happening.

Any time I restart windows 7 or reboot my NIC, my connection comes back with Limited Connectivity. I can solve this(the only "solution" ive found) by rebooting my router once everything is on and get my connection, but its becoming quite the nuisance. The router shouldnt be the problem, as there are other computers/boots connected that dont have this issue.Event log (Microsoft-Windows-DHCP Client Events/Admin) : Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x001A4D4F62E8. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.note that is NOT the error from DHCPv6(just DHCP under log name, not DHCPv6). The message is identical from what I can see, but thats not the source. And yes Ive already tryed disabling IPv6 without any success.

The Icon that shows my connection status is wrong. e.g: when I'm disconnected it shows I have wired internet connection, and when I have a wireless connection it shows that my internet adapter is off. How can I restore the the original icons' behavior?

However, recently my dad needed to reboot our modem several times because he was encountering problems with his laptop. This got the wireless working for a little while, but the need came to restart the modem again, so he did. Unfortunately, this put the wireless on the modem out of action. Originally, my laptop wouldn't even recognize the network's existence, but after a 3-hour-long tech support call to AT&T, our internet service provider, I finally got my laptop to recognize the network. Although the tech support lady through doing numerous things to both the laptop and modem, my laptop still will not connect fully to the network. By "will not connect fully" I mean that it gives me an error message, saying "connection unsuccessful", and on the list of networks, listed next to my network it says "Limited Access".
I've attempted to troubleshoot the problem multiple times, and so far the only thing that comes up is the message "Windows cannot connect to [name of my network]", and something saying I don't have a valid IP configuration. I have full access to the modem's configuration as well, and I've checked the firmware and other things to see if there is a problem with the modem. After numerous tests and diagnostics, nothing seems to come up that says there is anything wrong with the modem, but the limited access problem still occurs for my Dad's, my Sister's, and my laptop

I am having a problem with my Toshiba NB505 Netbook - running Windows 7 Starter. I can connect fine at home to wifi- and also at my local public library. However I was unable to connect at a motel I was at recently and had the same problem when I visited a different local library.To be more exact, I was able to connect ok at these 2 locations - but there was no internet access. From reading, I suspect a 'DNS' issue of some sort, but I don't know how to go about remedying it.

I've been having a very weird problem for a while now and can't seem to find anyone else who has experienced my version. Whenever I wake my PC from sleep the network adapter does not detect any networks (can't access my router either). When I run the diagnostic tool and it says that there may be a problem with the network adapter driver. However after 2 or so minutes the adapter suddenly finds the network and connects. When I run the diagnostic tool again it says everythings fine.

I'm running 7 Home Premium 64bit on an HP box we got about a month ago.
Lately, when I restart the system, I can't get any internet connection. I can access shares on my home network, so the nic is working and I'm getting an ip address from my router. If I disable and reenable the nic, the internet connection works again. I've tried disabling firewalls and things like that, but the only thing that fixes it is the disable/enable.
The network "troubleshooter" can't see anything wrong, and everything looks like it's configured properly, and nothing has been changes since the initial setup. It worked fine for a couple weeks and now doesn't.
Anyone seen this before? Hints? The disable/enable isn't a big deal but I know at some point I won't be home and my wife will have a problem and I'd rather not deal with that!

Two days ago I lost internet connectivity suddenly on my desktop (Dell XPS 630i, onboard Nvidia network controller, running windows 7 Home Premium 64bit) and have been unable to restore it. As my laptop (winXP sp3) can still connect to the internet and the router settings have not been changed (Dlink DGL4500), I'm making the assuption that my networking problem resides on my desktop alone. the network adapter gives me a 'limited connectivity' symbol and refuses to connect to my network, even though the router acknowledges the desktop's wired connection. The troubleshooting diagnostic sometimes finds nothing, sometimes finds that the computer is not obtaining a proper IP, and sometimes claims the problem is the router. I've also disabled windows firewall. Throughout this whole process I have been getting a 'Drive Power State Failure' BSOD during restarts (about once every four or five restarts, not consistently).
At first I was unable to replace the drivers or uninstall the adapter through device manager. After reinstalling the drivers using the Nforce 650SLI drivers on their website, I was able to do this, but this did not solve the problem. I also did a windows restore to before the problem occured, also with no luck. I've been through the event log and there are numerous code 5007 errors, which just tell me that the adapter timed out during an operation. I've also read through some forums online and tried several solutions including adding a DhcpConnBcastFlagToggle line into the registry: SOLVED: Network Icon Exclamation: No Internet

just upgraded my vista 64-bit install to win7 home prem 64-bit.
everything has been working great except for an internet/network issue. at random times, all of a sudden the icon in the tray gets that yellow exclamation point over it and says there's a network issue and no internet available. it's like that until i disable and re-enable the network adapter. there are other systems on the wired router and they're still working fine (vista and xp machines).
the strange thing is it *seems* to only do it when i start doing more than one thing at the same time. i.e. trying to watch Internet while playing an online game. or, downloading a pdf while streaming music. all of a sudden, all internet goes down (other computers still working fine though). once i reset the adapter, all is well.
any ideas here?

Yesterday I updated to v. 2.2 Of Sun Virtualbox and have lost my connection to the Internet on Windows 7. The 'VirtualBox Host - Only Network Status' reports "limited or no connectivity". This is because "the Network did not assign a Network Address to the Computer". I have not been able to solve this problem, the icon in the sys. tray has a yellow marker against it.
I have normal connectivity on Windows XP.
I cannot wind back using System Restore as there are no restore points. I do have a drive image of my C; drive dated just prior to the update, would this work?. Is there an easier way?.

I have Windows 7 on a Dell Inspiron 1545. Most of the time when I put my laptop to sleep and restart it Wifi network connectivity is lost and I have to click the 'Wifi Signal' icon in the system taskbar and click on my network name and click connect to regain connectivity. I have gone to 'Power Management' tab and cleared 'Allow Windows to turn off this device to save power' option as suggested by most posts but it has done nothing to help me. But sometimes even after a long sleep the laptop immediately connects back to the network and sometimes even if I just close the lid and open it after a few seconds network connectivity is lost.
