Limited Connectivity After Malware Attack?
May 5, 2011
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?

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 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.

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.

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

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'm having a problem getting my laptop connected to some wireless networks. I can connect to the wireless connections at work and home without issues, but I'm currently house sitting for my parents and unable to connect to theirs. Apparently I have 'Limited Connectivity' on an 'Unidentifed Network. DHCP works and is issuing an IP address (plus gateway and dns), but when I try to ping anything on the network I get 'destination host unreachable'. I've tried using a valid static IP and it's no different. I've tried using the Windows 7 troubleshooting tool and it's complaining that it can't connect to the gateway. I've reset and reconfigured the wireless router but that hasn't worked either. I can connect to this network fine with my phone and an old vista laptop.
Below is the output of ifconfig /all (using DHCP) Windows IP Configuration:
Host Name . . . . . . . . . . . . : Dan-Laptop
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Broadcast
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No
DNS Suffix Search List . . . . . : home
I'm running 64bit Windows 7 Ultimate and the wireless device is an Engenius Senao LR Multi-Client Bridge. I have already reloaded my laptop - there is now no software installed other than Photoshop, Office and Inkscape. I have no software firewall and no anti-virus. I've tried changing the wireless mode to 802.11g, but that didn't work. Bonjour doesn't seem to be installed. I've cleared down all of the known networks as well.

I work at a company in the UK which is attempting to start rolling out Windows 7 to all computers (early adopters and all that, it's just a lot easier than the current mishmash of OSes we have!). One of the 4 users migrated so far is having an odd issue with her wired network (her network controller is a "Broadcom Netlink Gigabit Ethernet"). She's the only person not from the IT dept or the MD of the company to be moved across, so we set her up as a non-administrator to avoid problematic software etc etc.
Suddenly, 3 days ago, whenever she switched on her computer, the connection would claim "Limited or No Connectivity" (even though she appeared to be connected to the Domain), and there was no Internet access. Having played around with numerous things (driver updates, both from Broadcom and HP - the laptop manufacturer, being the main one), I found the only way to get it working again was to disable and re-enable the network controller. The problem with this is that it required a UAC authorization (even though I'd set UAC to never notify), and that requires a domain administrator password (which is a pain in the wotsit).
Anyway, I figured, reluctantly, that if I set her account up as a local administrator, that at least it shouldn't require a password to reset the device. Rebooted the PC, and suddenly the wired network started working from boot without the need to reset the controller.
My question is - has anyone else had any issues with non-administrators being forced to reset their network controllers to get internet connectivity, and is there a known fix?

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.

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

I've noticed when using skype, or other webchat utilities like omegle - chatroulette, that the conversation can only last anywhere from a matter of seconds to 20 or 30 minutes before the connection quality drops and i get "limited or no connectivity" for my internet connection. I must reboot to get internet connectivity back, sometimes a couple times. Usually the first attempt will last at least 5 minutes, then subsequent attempts - after restarts - seem to get shorter and shorter sometimes only last a few seconds even. A few times i have been able to time skype calls because at exactly 3 minutes the internet would drop me.I have tried going to options - connections - unchecking pnp, or unchecking ALL boxes ive even heard in some posts. Tried that with not much effect. I have made sure that my firewall has exceptions for skype.
I have tried forwarding the port on my router that skype claims to use for connections in the options. I am using a linksys wrt54g wireless router but my connection is hardlines to the router. I am using an archaic form of DSL that is very slow on a phone line that has degraded but I am still able to play high-bandwidth using multiplayer games for long periods of time with no interruption. I recently took my computer to another persons house with a new router and much higher bandwidth connection and had the same problem. I have also noticed this problem when downloading torrents but reducing the number of peer connections seemed to greatly improve the problem - not completely eliminate it. I suspect it may have something to do with my hardware? I also remember clearing all temp files and resetting internet options helped for a little while but the problem came back quickly. Sometimes I have been able to have longer skype calls that last a good amount of time and it doesnt drop me but that is rare, i dont know why that is. I am almost beginning to think I have some sort of a virus that is interferring with the internet at times possibly from some remote source because the actions it takes seem to be "intelligent" at times but maybe I am just paranoid.
A couple odd things to mention that may mean somethingAfter restarting my pc a couple times to regain internet connection and retry my skype call, sometimes instead of my internet connection disconnecting i actually get a BSOD and my computer automatically reboots itself. Not often maybe 1 out of 10 restarts. It says something aboutIRQL_DRIVER_NOT_EQUAL_LESS something but its fast. this hasnt happened with chatroulette or omegle JUST skype.Also i noticed at my residence i cannot remove the router and hardline connect right to the modem it gives me "limited or no connectivity" at the house with the faster internet i went to, i could not use their router i had to hardline to the modem - the router would give me "limited or no connectivity"

When I started using my computer this morning everything was fine, and then "no network access" kept appearing, along with "limited connection/connectivity". I would troubleshoot the problem, but then at the end of the troubleshoot it would freeze, and my screen went black, so I had to turn my computer off and then on again. This problem has persisted throughout the day, I've googled it but nothing really the same as this has turned up .

Yesterday I was attacked by the s.m.a.r.t. trojan which has "hijacked" my files and hid them. I have followed the recommendation from Microsoft Answers, Security Essentials[URL] but it is not working. I got my desktop icons to show up but the screen is still black and I cannot see anything when I click the start button. It was suggested that I open up a new window in task manager, but when I click on Task Manager it reverts back to the fake virus scanner (S.M.A.R.T. HDD). I typed in "cmd" on the search bar, which opened up a dos prompt. I then proceeded to type in the following:
CD/ then hit enter
ATTRIB -H -R -S /S /D then hit enter
The prompt began to scroll through numerous files rapidly, but each line was preceeded by "access denied". So, when it finished, nothing was accomplished, as far as I know. I have not rebooted the PC yet. Any suggestion? I don't know if this was the incorrect thing to do, but, before I entered those dos commands I ran a copy of Windows Defender Offline Beta from disk. It said that it removed numerous trojans, but I fear that it only angered it. I will probably reformat my c:\ drive, b ut i want to gbet some files off of it prior to doing so.

I lost Windows Defender. I had a few Trojans pop in last week. It was the Sirefef.p, and a few others I can't remember their other names. I think I have gotten rid of all of them. Now just trying to get back what they took. I had an Error code "0x80070424" with my Firewall. I followed these instructions here: [URL]. My Firewall is back up and running now. But my Windows Defender isn't working. It isn't even in my PC any-longer. These Trojans even uninstalled my Microsoft Security Essentials. But I got that reinstalled. I just need to know how to get my Windows Defender back up and running. I am using Windows 7 Home Premium.

I am on a large LAN that I absolutely cannot disconnect from. I am using Windows 7 Home Premum with the latest updates. I use Comodo Internet Security (AV and firewall). Here is the problem: I am being hacked from the LAN level. What can I do to lock down my OS and minimize my attack surface? My Macbook doesn't succumb to this, but my fully updated Windows 7 PC gets hacked relatively easily from other users on the same LAN. I am experiencing remote code execution (IE9), unattended installs and system wide changes. What can I do to minimize my attack surface?

I searched but couldn't find anyone else with this problem. I'm running 7 Home Premium 64bit. I've tried everything and had a Pro try to solve this also with zero results. Somehow, Media Center has attached itself to every exe. program/file and I'm not able to open Firefox, Chrome, System Restore, regedit, and on and on. IE 8 does work. I managed to run a free Norton scan which showed NO virus. Remote access from Cloudeight to repair was thwarted, so no help there. I cannot run Malware Bytes or any other cleaner, so really need some expert help. This is being typed on my Gateway XP Pro.BTW, I was using MSE.

I am new to Windows 7 and have just come across the Vrtualization featuers. They seem interesting but I am not 100% sure of how they work.There are certain apps out there in my industry that people suspect might not be "clean" but they are very good at what they do. So I want to be protected from them. I used to use, Sandboxie with my Win XP setup.If I install or run a virus/maleware infected application, can I do so in a Virtualized way so that it doesn't infect the rest of my system?

First off Im running Avast and comodo and full malware bytes. But what Im wondering is if there is a way to check deeper for malware or issues? Reason Im asking is I think I may have downloaded an iffy program. My mouse seems to be studdering a bit ( and it didnt do it until now ) Im running a new build of only 1-2 mths old. So is there anything to look for in terms of processes etc? Or would Comodo, Avast and or Malware bytes have said something to me? Comodo kept popping up when I was installing it, but it does that anyway with any program.

why is there not a very good software program that will eliminate this problem? Many programs offer to identify and remove this malware but none do. Many offer a free download or evaluation but none will remove "About:Blank" browser hacker. Is this such an involved process that a specialist troubleshooter is needed to identify and then offer to remove for a price?
