I was on my laptop, connected to the Internet, going about as normal. My Wifi Internet went out completely and then would not reconnect. When I tried plugging directly in to our modem, it came up with error 633. It seems like one of my programs is interfering with it being able to connect. I haven't added or changed any programs recently, I've only uninstalled a few games/programs that weren't in any way related to the modem.
What programs could be the cause of error 633? Is there a list? Or is there another way to fix it? I can add more detail if needed. Well, I went out today and left my computer on while I was gone. When I came back, it was connected to the Wifi again. I've been using it for a bit, but now it's going on and off again. It's on for the moment though...

I've had windows 7 for months now on my new computer, but one day programs just seemed to stop working on the internet. First it was chrome, then it was a few games. Occasionally when I restart my computer everything can connect again. But it's starting to be more frequent that I can't. However, skype has managed to connect 100% of the time. I also noticed that it takes quite awhile for the computer to connect to the internet.
So far I've tried making new user accounts, renewing my ip, and uninstalling some new programs, but no luck at all. My antivirus picked up an infection but cleaned it, it's nod32 AV5.
edit: Ran windows 7 help and it found that it can't connect to the DNS server.

This BSOD has been happening more regularly, sometimes after 30mins, other times after a couple of hours.If I try and restart it crashes shortly after Win 7 logo appears.Unless I disconnect the power for at least 15mins, it won't restart Windows - just re crashes.Have attached the dump and sysdata files - note that the two files are not always written.

I have a laptop w/Windows 7, we also have 2 other laptops using 7 and one using XP. We are constantly getting disconnected from our wireless internet. Sometimes it will show that it's connected but then show "no internet access". We also have a Wii, PS3, 2 iTouches and 2 iPhones. Could we be overloading our wireless router? It probably happens at least 2 times a day. We are always having to unplug router and modem and starting over. I've reset the router several times but still have same issue.

I have an HP G60 laptop with preloaded Windows 7 Home Premium. The OS has been fully patched till date, and guaranteed to have no viruses. I have MS Security Essentials and Super Anti Spy-ware installed and working. Lately I notice that each time I close the cover and open it back the OS resumes all right but the internet connection is lost. No amount of trouble shooting through Windows helps. Of course rebooting solves the problem. My internet connection is through a Scientific Atlanta cable modem connected through the LAN connector, and so requires no drivers.

I've been wondering if Windows 7 has capabilities to trigger sound alarm when the network connection icon in the bottom right corner changes due to internet/network disconnection. I guess, in theory, Task Scheduler should come in handy, but first, the correct Event ID for the above-mentioned change needs to be determined. I couldn't find it yet. I found a standalone program NetSNSOR that can trigger alarm. However, a built-in process would be more useful.

I've discovered an odd issue with my computer. When there is no internet connection, it goes extremely slow. Simple programs such as VLC and ACDSee took something like 10 seconds to open. These programs are also installed on an SSD which makes these figures even worse than they would normally seem. Anyway I figured it was an issue I could fix with a reboot, however when windows was starting up, at the point where the desktop would finally appear, black screen. I can ctrl+alt+del to open task manager and I could see that there were 6 processes open, and nothing else was continuing to load. Safe mode with networking suffered the same problems.
At some point I disconnect the computer from the router, intuition I guess, and viola! Everything starts loading fine within 10s of disconnecting it from the router. I restarted multiple times with it disconnected, connected, disconnecting after few mins of black screen to confirm that it was the issue, and it indeed is. Same thing happened with Safemode with networking. Disabling the NIC seems to fix the issue as well. And of course when the internet came back on, it works perfectly fine.

I used to use my laptop to connect to this router's wifi and have no problem at all.Recently I am unable to connect to it most of the time, and it shows a yellow triangle on the wifi signal icon with an exclamation mark , sometimes okay but then very slow. iPad and iPhone can both connect to the wifi with no problem, and my friend's laptop is fine as well.So it seems that it is my laptop's problem.I tried to use the cable to connect and is fine though somehow still a bit slower than normal

We have a windows 2000 server, a few XP, 1 vista and 1 windows 7. Everything works fine before but all in a sudden, only the Windows 7 cannot connect to the server. The 7 is a new PC, it works and connect to the server fine for the first 3 months, but all of a sudden, it just cannot connect and keep prompting that the user name and password is wrong. I have re-install the 7 (it is HP and we use the recovery disc) and I even get a new wireless adapter to test, the 7 can get on the internet, everything except the server. But all others windows has no problem with the server, I am guess it has to do with the 7. I am getting so frustrated that I also gonna use that HP windows 7 into a door stopper.

Right, just a few days ago without making any changes, I can no longer detect the wireless connection in my house (which is definitely still working as it comes up on my phone).

A few days ago my computer (an ASUS Eee Netbook) suddenly stopped being able to connect to the wireless network in my apartment, seemingly for no reason whatsoever. It had been working fine earlier in the day, I went out for about an hour (didn't even shut the computer down), returned home and was unable to connect to the network. The computer can locate the network and continues to attempt connecting to it with no luck. I can connect to other networks without any trouble. It has never done this before. I've rebooted the computer several times and performed a System Restore, but without any success. I'm hesitant to reset the router as this is a shared connection with the other people in my apartment (who as far as I know aren't having any trouble with the connection).

I need to connect to a VPN in order to use my university's exchange email client.Does anybody know if I can define it to connect automatically when my system starts? As it is, I need to manually connect each time (which isn't that difficult, but I rather not having to do it).

I have two computers and I use them both a lot. They are both for work. I have Input Defender to allow me to use my mouse on both screens. Unfortunately, quite often my laptop seems to boot up and isn't connected to the network at all. I have to restart it and / or just wait till it decides to connect. Sometimes hours.
How can I figure out why it's not connecting to the the network and / or Internet.

Suddenly, my direct connected (Cat 5 to the broadband modem) computer is asking me to dial a connection. It no longer seems to know that it is simply connected. When I look at the devices tab, it shows Enabled for my network card and I have tried to reinstall the drivers.I dual boot with Ubuntu and Ubuntu is able to access the internet (and network) fine.

DV6700US seems to have lost the wireless network connection. A sudden failure to print gave me a printer offline message. My iMac printed fine, then I realized my iMac could not see the laptop and the laptop could not see the iMac nor printer, but still has internet connection on the laptop. I now nothing about Windows 7.

i recieved my new lenovo z570 ideapad yesterday...i'll just put some of the spec down incase you want to know.
proccessor: intel i5 (second gen)
graphics: nvidia geforce
os: windows 7 64bit
yadayadayada...
anyway, after charging it up and turning it on, i started to install programmes and other bits and bobs. e.g ituens, flash player. just the usual essentials. i used the laptop to watch videos on Internet, genenral browing such as facebook, so in short, the internet was working fine. just before i went to bed that night i installed avg security (free version) and ran a full scan. when the scan finished, i put the laptop into hibernate, and went to sleep! happy in the knowledge my new gizmo was running smoothly!
just before i woke up i heard the laptop turn off as it had run out of charge. so i plugged it in and charged it up, then turned it on. this is where the problem starts...i connected via wifi however the logo at the bottom right of the screen showed the signal strength meter on empty, with a yellow star covering it. i clicked the icon, and it said, 'not connected, connections are available' and below shows im connected with 5/5 signal strength, but on 'limited access'.
1) there might be a problem with the driver for the local area connection adapter
2)there might be a problem with the driver for the wireless network connection adapter
there are 28 updates, but im unable to update them as i have no internet connection. i also cant connect via the ethernet cable.i cant roll back the drivers as there are no previously installed ones, and i cant update them as i am already up to date.my other laptop (acer aspire 5630 running on vista) works perfectly fine using wifi and the ethernet cable, so i honestly dont know whats wrong. after reading things on my acer about ways to fix the problem i came to the decision to restore the laptop to the time of my first installation which was adobe flash player (which i installed the day before.) i was unable to do a full factory reset as the only options available are to either restore to a backup, or re-install windows (which requires a disc, which i dont have). i also didnt configure a backup as i had only had the laptop a day!

Toshiba Satellite M645-S4065 (LAPTOP)
CPU: Intel Core i3 M370 2.40GHz dual-core
RAM: 4GB
System type: 64-bit
1) When I restart, my computer stays stuck at the "Shutting Down..." screen for 15 minutes. I then get a BSOD, then it restarts, I get the prompt to start up as safe mode, etc., and then I'm back to the main screen. The BSOD reads: driver_power_state_failure
2) Connecting to the internet, whether by my phone's hotspot or ethernet cord is really problematic, especially by cord. It often hangs and I have to restart the computer or wait a really long time. The taskbar icon hangs with the spinning Aero circle perpetually. And attempting to open the networking controls just freezes.

Generally once or twice a day, my computer will suddenly drop its internet connection.It will then start an endless loop of trying to connect: Sensing the network is there Trying to connect (With the loading symbol and "Initializing")Appearing to connect successfully (but when I try an open a web page, nothing loads, and I receive an error message telling me there's no connection)A few seconds later, the yellow triangular warning sign appears next to the wireless bar.A few seconds after that, it drops the connection, and then starts over at step oneA few seconds later, it will start again at step one.The only way I am able to get the network back on is to: Disconnect manually (press "disconnect")Turn of my wireless antenna on my computer Turn on and off my router Turn back on the antenna Reconnect.I have to do these 5 steps every time it disconnects.This is only happening on this one computer - other computers on the network aren't experiencing the problem (running XP and Win 7).I have an Asus U56E-BAL7.

I CAN connect to internet just fine using my wifi BUT I CAN NO LONGER connect to 198.192.1.1!!! Any idea how to solve this problem? I'm using a Dell Insprion 1545 and Win7 32-bit. I never had this issue before, jut popped up when I tried using ICS on a different laptop, an IBM thinkpad T42 also using Win7 and connected to the same network via wifi. Again I can connect to the internet just fine on all my laptops, but 192.168.1.1 (for my netgear router) returns "unable to connect" page!!! have verified (via ipconfig) that my gateway ip is 192.168.1.1. I have valid IPs on all the laptops, but cannot connect to router setup page.

My computer is relatively recent only being bought back around Feb/March. For the past month the machine has been crashing and when I log back in I need to restart my router in order to get my internet connection back. The strange thing is that other computers connected to the same router also lose their connection shortly after the BSOD on my machine (both machines have wired connections). I am using the same OEM copy of Win 7 Professional 64 bit that was installed when I bought the machine.I have tried updating the drivers on the network card but that does not seem to help. I also tried looked at the dumps with WinDbg to see if I could find a specific driver that was playing up. I also turned on the driver verification a couple of times to see if I could find a driver that was suspect -- that caused almost immediate crashes but I could not get to the bottom of what was causing it but it could make it happen by starting up Mumble.The BSODs have so far seemed to happen when I am playing a game, using something like Mumble, or watching a stream.

When I open IE all I get is "Internet Explorer cannot display the web page." I know it is connecting to the internet because it downloaded the updates. I downloaded AVG, Adaware SE and Spybot Search and Destroy on another computer. I put these files on a cd. I tried to install AVG and Spybot but they wouldn't install because they couldn't connect to the internet to get the necessary files to install. I've had this problem on friends computer some time ago but can't remember exactly what I did to fix it
