No Network Connection Suspect Malware
Mar 24, 2012
Running Windows 7 Home Premium, Dell OEM install.The symptoms are:No wifi connection, adapter does not show in dev manager. It is just missing, scan for new hardware doesn't find it.Will not connect via ethernet...no internet access.It will not renew or release its IP address, says there is no device in permissible state for this operation.The computer had obvious malware, there were a bunch of sketchy items in the startup. I ran several malware tools, they found and removed hundreds of items. The computer had an expired installation of Trend Micro, I removed that and used the removal tool from Trend to be sure it was gone. I do not know if it has had other security software installed in the past, I ran Norton and McAfee removal tools since those come on most PCs.
I have tried resetting winsock and TCP/IP, to no avail.I know I need to probably reinstall wifi drivers to get the card back, but that's next after I solve the overall connectivity issues. If this were my PC I would have just Re-OSed by now, and I may just suggest that to him.

My wireless key is turned on, and I know it has nothing to do with my router at my apartment because my friend's wireless connection works fine. I know it has something to do with my own computer because I am in college and I cannot connect wirelessly off-campus at my apartment or on-campus using my school's wireless network connection.

while ago, I got a virus that tried to mimic windows activity center. Since then, I have use malwarebytes anti malware, ccleaner and microsoft security essentials to scan and remove the virus.Usually what happens is that I will be using firefox, and all of a sudden most of my programs would exit, and one of those fake virus scanners come up (Microsoft security essentials also turns off if that is important). I open the task manager, and identify the program. I open explorer (as i can't open mbam, or mse) and delete the file. While it is in the recycle bin, I can open mbam (for some reason, it asks what program to open mbam with, I just pick mbam from the list) and I scan, and remove the threats. Then I empty the recycle bin, and use ccleaner to fix the registries. Lastly, I use mse to scan the computer.Everything works for a while until it comes back again....and again....and again. I've tried the same steps in safe mode and again in regular mode. It's still happening.

My computer was recently infected with the XP Antivirus 2012 rogue virus. I believe that it has been removed from my computer, but I am unable to connect to the internet. I am unable to obtain an IP address. The IP address is 00000 and the Submask is 0000. My operating system is Windows XP and I am using a High speed cable connection

I have an Acer 7750G, running Windows 7,connected to our home network using a Dynex router. At the moment this is the only laptop in the house that is having problems with connectivity. Starting yesterday, it only connects intermittently. When I run diagnostics, it says the following problems have been fixed but it either solves the problem for a few minutes only or not at all: "Problem with wireless adapter or access point" or "Default gateway is not available".
IPV6 connectivity also shows 'no internet access' and sometimes IPV4 reports no internet. I've unplugged and rebooted the modem and router a few times but that hasn't solved the problem.
Edit: I ran troubleshoot again, and it says the following issue is not fixed: "Wireless Network Connection 2 does not have a valid IP configuration".

I use my desktop for streaming media throughout the house. I found it was causing lag for gaming most likely because it was taking up all the bandwidth for the router. We had a 2nd router laying around as well as a 2nd wireless adapter so we set up a 2nd network that was not connected to the internet for strictly media streaming.I attempted to change the network settings so the internet connection appeared as a public network so that streaming of media was hopefully diverted to the non internet wireless adapter.I want a faster way of transferring large video files from my laptop to my desktop. I recently bought a crossover cable to do this through direct connection.Both use the same user name and password as well as run the same win 7 pro however the desktop is the 64 bit version. I set up both ipv4 with the same addresses.When it has worked I am only getting a connection speed of just over 10mb and once I connect the crossover cable between the computers it knocks out my internet connection on the wireless card.

I have a problem with my home network (diagram attached below). I sporadically lose connection between my Router and the devices behind the switch. I have replaced the Ethernet cable between the 2 so I don't think the problem's there. It will work for a week or so, then just lose the connection. I then try a combination of rebooting all of the devices on the network and/or unplugging and re-plugging the cable connections and sometimes that works. It's a relatively new router, but can a router be "underpowered" for pushing a signa

There is a device which is connected to the PC via Lan. I have an exe file which is supposed to get connected to that device and perform some operations. However, the problem is, the exe file tries to connect to the local host ip address 127.0.0.1 and i cant change the ip since it's been coded.So, I'm wondering if i can use the device connection (which already has a different ip like 169....) as a local host connection. So whenever it tries to connect to the loopback 127... it automatically connects to the external device.

I have a windows vista SP2 laptop, with an Intel wifi link 5100 adapter and a Realtek PCIe Family LAN adapter. From some time ago, I'm having this issue: each time I want to change network (from my job's to my home's, for example) I have to disable/enable the adaptors. This was not needed for over a year and so I own this machine, and I think It might have something to do with a network drive some IT guy in my new job installed

Every time I start Windows XP, I see an icon of Internet connection being established, and then a connection error icon with a pop-up window. When I click on it, I see the connection window with a notification that no IP address has been assigned.In order to get an Internet connection, I have to click "repair" every time. I have downloaded and used TCP/IP and Winsock repairs without result. I use WIN XP SP3 and run updated Avira and Comodo. I am aware of damage left behind by deleted malware but don't know where to look.

I have noticed a few times over the last month that my PC would not load pages due to connection problems. If I hover over the Network icon, it say that I am not joined to a network but within minutes, it reconnects itself. I use http://www.scan.co.uk/products/zyxel-pla-4201-500mbps-mini-powerline-adaptor-twin-pack power adapters and they "appear" to work well with good speeds as I download and game online alot. I have noticed that today the problem is really bad. It loses its connection every 5 or 10 minutes and then reconnects itself as if nothing has happened. I tried using my iphone on the wireless and it also seemed to have dropped out on connection. I have tried resetting my router too but with no joy

I have a Win 7 laptop which keeps dropping its network connection. I have changed the power management option on the network card so it can't turn itself off, but it still goes to sleep after a certain amount of time.I've also tried with a different docking station and network cable in case that was an issue, but the same thing happens. Event viewer does not reveal the cause of the drops.

I have a print shop that runs several computers on one network off of a single adapter. Last week the boss and I went out of town for some off site training leaving a single employee in charge of holding down the fort. When we came back we ran into a whole slew of problems not the least of which being that one of our graphics computers doesn't seem to want to recognize the work network anymore. It seems like the employee who we left (who, of course, "didn't touch anything") must have disconnected the computer from the network and started a new one as it is connected to one simply entitled "network". The issue I'm running into now is that when I check the network list the work network is not showing up at all. I've checked and I can ping the other computers on that network, they are all connected to the same network adapter, I just can't seem to get this one computer onto the preexisting work network.

So I've had this problem ever since I bought my computer. The only wireless connection that I am able to connect to, is the one in my home. If i travel anywhere else, my laptop refuses to let me connect. The thing is, my laptop sees the connections, but when I click "connect", the box closes and nothing happens. The laptop seems as though it doesn't even try to connect to the network. Everything remains the same, yet when I come to my house, it connects automatically. Now if I click "Add" on the network config. it won't even let me add a network to my computer or anything. I click the "Add" button and nothing happens. I am running a Windows XP.

There is a computer at a job location that MUST have internet access, but the property manager at that location does not want the computer to be in their network for security reasons. Is there anyway we can create a new network and still have internet access with out being in the property's own network? Is it as simple as just creating a new network?

I'm looking to improve my connectivity,as the internet drops out a few times a day.Let me explain - I hope I'm correct in my assumptions.Every few hours, my PS3 will have a DNS error, and upon checking my iPhone, I notice that it's switched from wifi over to 3G and there seems to be a loss of connection. I cannot reconnect to the internet until I've restarted my router, or 'forgotten' and rejoined the network.
Additionally, we have an Apple TV, and connection drops out about 3 or 4 times every hour, which is very frustrating when trying to watch a movie.

I had this problem since I installed this game (GTA San Andreas). So, I found that it keep auto alt tab when I play GTA only. Not other game. When I restart, it is gone. and will occurs when I open GTA. So, i try to scan and delete the game and the problem fixed. Still, when I install FiFa 2011, it is also happening. So, I deleted the game but the problem didnt fixed. Well, I also download Sims 3. and when I play the game, I tried to remove my Tenda Wireless reader, then the auto alt tab is no more occurs. So, it seems like I have to play games without using internet. Which means I can't play online games. So, I am telling you guys that I am having problem with auto alt tab/ losing focus when playing game/using programs like google chrome. So, what should I do for know? I think it might cause of my Tenda Wireless Reader? I'll try to use wire into my wifi then.

Windows VISTA, LINKSYS 1200 Router, Cable Internet Surfboard Modem.I have cable internet connected to a modem which then connects to a LinkSyS Router with a CAT5 cable.My computer was direct connected to one of the ports, and the two other laptops in my house are wireless.Lately my speed has been dropping from 20-25 Mpbs to <5 Mpbs. So I figured everyone else was, but saw everyone else was still getting full speed.I managed to find another cat5 cable around the house to change the one from the Router to the Computer, but it was 100Ft. long, however, my speed came back up again. BUT....the next day, it went back down and stayed down, while everyone else was still up.
To elminate the problem, I had a RTL8185L PCI wireless card from another computer to connect wireless like everyone else. This card says it connects up to 54 Mpbs, but the connection caps out at almost exactly 5 Mpbs every time. It shows I have excellent signat strength (since I'm 2 feet from the router).What else could I be missing? I elminated the network card that the CAT5 was plugged into. Does RTL8185L have a history of slow speeds? Is there something on my computer causing problems to ANY network connection?

I've been watching my PC-s HDD for months and I saw that something takes up way to much space, yesterday I checked and Windows said that I have 160 GB Free / 883 GB But when I selected all files in my E: even hidden files and checked their properties / size, it said its only 440 GB. So I was missing another 283 somewhere in this partition. I used the windows cleanup tool and it gave me back some of the space, but it wasnt 283 GB. I checked and checked, then I found a program called WinDirStat which shows you how much space you have and stuff, then I found this: [URL]Then I found out that WinDirStat cannot access the System volume informations and this unknown is that. Then I googled stuff up again and found this:
Code:
1. To see the space allocated and used for SVI:
- Open Command Prompt with �Run as Administrator� option
- Type in: vssadmin list shadowstorage
- You will see Used Space, Allocated Space and Maximum Space for SVI
2. To see the restore information stored therein:
- Use in the same console command: vssadmin list shadows
3. To resize the maximum allocated space:
- Type in command: vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]
- E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB
- You will see a prompt confirming resize done
- You can check the status again using the command discussed in point 1 above
4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:
- Do actions as per point 3 to set the max-size t, say, 1GB
- If you check now, most likely you�ll see that used space is now 0KB
- Do the resize again and set it back to what it was before
- Check your disk space availability in Windows Explorer, you should see the reclaim is done!I did what this guide said and it deleted the system volume information from my E: drive and I had my 440 GB back. BUT!At this part I HAD internet connection. I shutdown the PC, went to eat and do stuff, then I came back and got a blue screen right after the win7 logo (before the log in screen)I couldnt read what it said, because the PC restarted itself (even tho it is set NOT to restart so I can read the errors...wierd!)Then it started repairing itself, restarted, asked for a chkdsk, fixed millions of errors then restarted and I logged in just fine.But in the bottom right corner I seen a big ugly red X over my network connections, so naturally I went out my room, restarted modem and router then came back. Waited some mins, checked the modem and router again but they had internet. I started my sisters PC and her PC had internet.I checked everything I could, but I couldnt revive the internet, I cant join to any network (home, private, work) and I cant even see any. I only see dial up connections, hamachi and tunngle.Then I tried to resintall the driver. Deleted driver, restart PC, win automatically installed the nvidia driver for me, but still no internet. Then out of couriosity I started my Virtual PC (win xp) to check if it has internet connection or not. And it has! I am writing from the Virtual PC now.So the network card is working perfectly, no hardware damage.I googled stuff up again to find a solution and then I found this thread: Loopback Pseudo-Interface 1I did what it said there and my result was different:
Code:
Windows IP konfigur�ci�
�llom�sn�v. . . . . . . . . . . . : Dezix-PC
Elsődleges DNS-ut�tag . . . . . . :

I recently upgraded my internet to a faster speed. I received a new router. I am able to connect my laptop via ethernet connection without any issues. I am able to connect my laptop wirelessly both at work and at school. I am unable to connect wirelessly at home. I can connect my stand alone computer to my internet connection. I am also able to connect my smart phone to this connection. When I attempt to log into the internet connection I enter the passphrase as instructed the entire screen goes blank and when I try to reconnect the computer is automatically entering a different passphrase and gives me a message "waiting for network" then it disappears and I am not connected - when I attemp to correct the passphase it will not store the new setting. I have tried updating the driver - changing the passphrase - restarting the computer, I have used the diagnostic check provided by Century Link and spent over 4 hours on the phone with them trying various things without any connection.
