No Internet Connectivity After ZeroAccess Rootkit Removal
Sep 20, 2011
Google Redirect/rootkit infection (See here), I managed to get more or less rid of the thing. After this, I have encountered a "c0000135 %hs is missing" BSOD just after the end of Windows loading that I corrected by modifying the registry following. So now my installation works properly except that no internet connection is possible. I've been trying to do it via ethernet, wifi and mobile phone tethering and it just doesn't works. No IP address displayed, even when I try to force a manual IP (normally everything is sorted out via DHCP) or flush all DHCP/DNS... infos, the diagnostic tool from Windows concludes to a possible defunct driver. I've got a clean installation of W7 x64 (same version, up to date) on another hard drive and of course, everything works well (it's from this installation that I managed to properly clean up the other one and modify the registry). Little detail : I uninstalled Zone Alarm in a not really proper way so it may be something with it too.

I'm trying to fix my girlfriend's Windows 7 laptop after she had a virus/malware infection. I'm pretty sure we've successfully cleared the virus (an updated/full scan with Malwarebyte's Anti-Malware in safe mode comes up clean). However, we have had no Internet access since the infection. The wireless router/connection itself is fine (I connect to it daily with my laptop, as I am to write this post) but her laptop won't connect to it, we can't browse any web pages.I may have made the problem worse in trying to resolve it. I stupidly followed the advice on a forum for some registry edits for Windows XP--deleting WinSock and WinSock2 from the registry and then restarting the computer in hopes they'd re-register themselves. Unfortunately, WinSock2 re-appeared but WinSock did not. I'm wondering if this has created a new problem (or compounded the problems we were already having).In diagnostics, we currently get the following report: "Wireless Network Connection doesn't have a valid IP configuration." I just ran an ipconfig in the command prompt and got the following results:
Windows IP Configuration
Host Name . . . . . . . . . . . . : Elizabeth-PC
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No

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?

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?

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.

My wifi was working fine a few days ago but i think the windows update has messed up my wifi adapter or connection. I did do a system restore when this happened a few days ago but since the restore is more then 1month old it is no more.So far i have tried the following:restarting/rebooting router,updating/reinstalling drivers,and many other things but nothing seemed to work i dont understand why it is scanning for wifi but on the mapping it says adapter isnt connected.I have shown a few pics to help you:

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?

Whatever modem/router I use (except my old 2Wire that died in Dec. 2010), I lose connectivity after I resume/wakeup. The tray icon says "connected", but my browser (Firefox) or my email client (Thunderbird) say "no"!

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.

I have a few computers that connect via rasdial to a bridged modem. They are dropping off randomly and frequently enough that its a pain to have to reset them manually everytime. How I could write a script or something that would check for internet connectivity and if there is none then it would re dial the pppoe connection?

On the right hand side of the taskbar I have the icons for battery life, volume, internet connection, etc. When I used to put the mouse over the internet connection it would show me who I was connected too (SSID) , signal quality, and speed.I began having some issues so I had to remove my Netgear connection and then reconnect.Ever since I did this all that shows up now when I put the mouse over it is now only says: Netgear and Internet access.How do I get the information back. It shows up on my desktop, but not my laptop.

I'm trying to fix my sisters laptop, which just wont connect to the Internet. I've checked everything I can find. Here's a description of the problem - When looking at the icon in the system tray that shows the connection bars, when I hover over it, it says "not connected - connections are available" . On the related pop-up window It does show my wireless connection. When trying to connect to that wireless network, it eventually says "the connection was unsuccessful - this computer has limited connectivity to "bthomehub.....".
At this point it gives an option to troubleshoot, when I select this it says - "problems found - there might be a problem with the driver for the wireless network connection adapter". If I look at the troubleshooting report from this window it says "windows couldn't automatically bind the IP protocol stack to the network adapter". In 'network and sharing centre' it shows the computer being connected to the homehub, but no connection from homehub to the Internet. Attempted to ping ebay, got this response - "ping request could not find host ebay.com please check then name and try again."
Under wireless connection status it says -
"ipv4 connectivity - no Internet access"
"ipv6 connectivity - no network access"
From looking around on the internet I have tried the following -
- netsh winsock reset catalog
- netsh int ip reset reset.log
- reinstalled drivers for wireless network connection adapter
- checked that windows has no restore points
- tried ipconfig /release at command prompt, got the error "the operation failed as no adapter is in the - - state permissible for this operation"
- tried ipconfig /renew at command prompt, got the error "the operation failed as no adapter is in the - state permissible for this operation"
I tried removing various antivirus/system protection apps...at this point I then got a yellow icon over the connection bars in the system tray, and it now says im 'connected'. but it says 'no internet access'. Its a new laptop running windows 7, it did work fine for a while and then suddenly stopped working while connected to the internet.

Our PC internet quit working a few days ago. Our wireless laptop and Ipods work. After some (hours) of playing, I noticed our homepage was set to something Babylon. So realized we had some virus issues after research. I have run SpyBot S&D, SAS and Malwarebytes- all came up with some various serious threats. CouponBar, Babylon, I want it! etc. These programs seemed to have removed all the problems, but I still do not have access. My LAN can find my network, but says "no internet access" the wireless does not connect either on this PC.
My computer knowledge is minimal but after comparing various ipconfig screens, it seems to have something to do with the IP addresses. I read that 169.254...is not good. I disabled IPV6 and when obtaining IP addresses automatically didn't work- I typed in the ones listed on the details part of the adapter. Here is a screen shot of my IPconfig/all with LAN only: Windows IP Configuration Host Name . . . . .. . .

I've been having heating issues with my GPUs, they reach 60c on idle, and going around a few forums, I've noticed a services.exe in a few different places and a strange user, HomeUsers, who is not inherited and has special permissions which apply to "this folder only". When I go into change permissions, the option is greyed out. Anti-virus isn't picking anything up (McAfee) and a check disk showed nothing. Do I have a rootkit, and if so, what can I do?

I had Windows 7 32-bit running on a Dell PC. About one week ago, I noticed Internet connectivity was gone and that there was "limited connectivity" as I was now connected to an "unidentified network". The other systems on the network are still connected and working perfect; the problem is isolated to this one system. The network uses a static IP scheme. "IPCONFIG /ALL" shows that the IP is assigned, is included on the correct subnet and has the correct gateway and DNS information. I've tried a host of solutions suggested on forums; from "route delete 0.0.0.0" to disabling my firewall to configuring for a dynamic IP. Nothing has worked. Reluctantly, I resorted to a fresh install as I began to worry that I may have picked something up. I completely wiped the hard drive and did a fresh Windows 7 32-bit installation all only to have the same problem. I assume that the NIC is functioning as it accepts all IP settings.

I recently installed a new SSD and put my OS on it but every now and then when I boot up it just wont get an internet connection.Once its booted up and I restart Windows though its fine.It doesn't happen everytime but 50% or so I'd say on boot up.I'm thinking its something to do with how fast its booting up now and for some reason my network settings or drivers have not had a chance to load or something and its not getting a handshake with my router.

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.
