Computer Is Unable To Connect To Internet / Can't Even Change Brightness Of Screen
Feb 7, 2012
I just formatted my entire laptop (Samsung RV511) due to a bug that was in the system my antivirus could not detect or the help of system restore would not get rid of either. My previous 2 laptops came with recovery discs but the samsung had only come with the windows 7. I had installed Windows 7 and after doing so, checked everything out. I realized that Samsung has many specific programs and drivers that come with their computers and in the process of formatting, I had deleted everything. My computer is unable to connect to the Internet and I can't even change the brightness of the screen anymore.

Is there an util where I can make the fn key always "pressed" so I don't have to press it when I want to e.g. change the brightness of the screen? My laptop is a Presario CQ70.

I am currently running Windows 7 RC1 and have noticed a behavioral change from XP which I would love to change.
In the NVIDIA control panel, there are 2 sets of settings for brightness:
1) Desktop color settings
2) Video color settings
In Windows XP, these would be completely independent. Thus for example, I could have my desktop dark while the videos could be bright and vivid.
Thus in XP:
Desktop Brightness = Desktop color settings
Video Brightness = Video color settings
In Windows 7, the OS only behaves this way when using Aero Basic. If I'm using the full Aero interface, I get the following behavior:
Desktop Brightness = Desktop color settings
Video Brightness = Desktop color settings + Video color settings
I would really love to have these control act independently on the full Aero interface. Is this possible? NVIDIA settings can obviously still distinguish the video because the video color settings still only apply to video, so I'm not sure why it behaves this way.

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!

When I first reinstalled the windows 7 it worked fine and I was connected to the Internet using my belkin USB adapter. But after moving my computer to a new room the Internet connection stopped working. Ive ran trouble shooters over and over and it says its a router or adapter issue, but all the other computers in the house are connected to the Internet just fine. I've reconfigured everything, restored and I was told to post here!I also want to add that it connects to the Internet but after about a minute it gets the triangle with the ! And acts connected but I cannot open any web pages or open any online games.When I trouble shoot it still tells me that Its in the adapter, router, modem, gateway or related issue.

I recently got Windows 7 on one of my desktops. I plugged in my Logitech 5.1 speaker system and I am getting absolutely nothing out of them. I went through the obvious checks (not muted). I was then searching my computer for evidence of the speakers even being recognized, and as far as I can tell they are not. I have Realtek High Definition Audio, and I've tried disabling/enabling this several times accompanied with a couple restarts of the computer.I understand I may need to update my drivers but at this point I'm unable to connect to the internet (Will have access in a couple days). I have searched this problem on my other computers and I'm getting mixed answers. I've heard my soundcard may not be compatible, the drivers are out dated, or I may want to use something other than Realtek.

I am unable to connect to the internet in wireless mode. It shows the available networks, but does not connect when I type in my router password. I have tried everything I know of. Uninstalled/Reinstalled the driver - I have an Intel 5100 AGN wireless driver installed. I disabled and enabled it. Didn't work. Running command prompt and typing in ipconfig /all doesn't detect my adapter device - says "Media Disconnected".I also did these by running command prompt as an administrator: Reset WINSOCK entries to installation defaults: netsh winsock reset catalogReset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.logReset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.logand restarted my computer. I have a Dell Studio 1555 with Win 7 (32-bit) Professional.What am I supposed to do now? Please help!PS: I know this is a problem with my Windows as the wireless works seamlessly in my Ubuntu.

I've been having connection problems for the last year, it's really annoying and so hard to understand whats happening. The internet connection is my dads, he lives in the garage beside me. He's with talk-talk fibre optic. The small modem type thing that connects is in the garage along with the main router that connects to the small thing, not sure what this is but it obviously connects to the fibre optic.His PC is connected to the router by wire, there is then a wire that runs from that router up through the garage and into the house through the wall in one of the bedrooms, this is were I have a router or two, (i've tried two routers with mixed results.) I'm connected via wireless through the second router in a room upstairs and get full signal when connected. I have a belkin 54g and a netgear dg834n. Now this morning after leaving my computer on all night, i woke up and it wasn't connected. Although this happens everyday when i turn my laptop on, i have to connect via wireless to the main router in the garage, then reconnect to the router up stairs to get the connection to come on. This time round it wont work at all. The netgear gives me - "Windows Networking TroubleShoot Error: The connection between your access point, router, or cable modem and the internet is broken."

Drivers are up to date and network card is 802.11n Wireless LAN card from Ralink technology Corp.

friend has just taken delivery of a Virgin Media all-in-one hub and can't access the internet via the ethernet connection but can via wireless.I've got the pc here. Here's the state of play:Her pc can access the internet via MY cable modem.My pc can access the internet via HER all-in-one hub.I cannot get her pc to access the internet via HER all-in-one hub (which mirrors her experience).So, there's nothing wrong with her pc because she can access the internet just fine via my connection; her all-in-one hub seems fine as I can access the internet via it.....it's just her pc and her hub that don't seem to like each other!'ve tried ipconfig/release etc to no avail.If I type 192.168.0.1 into a browser window, I can get into the all-in-one hub's setup but there's nothing unusual in there.

I have two other computers connecting to my 2wire modem and they are both working fine. The last attempt was installing a new network pci card. I have also swapped out the cable but i still get "Identifying... No internet access."

My laptop is 1 year old and has worked great until a month ago. I was unable to connect to the internet and thru troubleshooting got a "missing network adapter". I have since upgraded the driver. I also purchased Registry cleaner program that supposedly found over 400 registry errors.I found by accident that I was able to connect normally if I turned the PC off by holding the power button. Then restarting, I got a message to start windows normally. When I did, and then it connected to the internet normally.Now, each night if I leave the power connected to the laptop and shut down windows from the Start command it works fine. I do not want to have to leave the power connected. Toshiba tech support is unable to help other that suggesting I return the PC to the "out of the box' status which is totally unacceptable to me.

My windows 7 machine is unable to connect to my internet through the wireless bridge I've set up on my WRT54G using DD-WRT. It seems to be connected to the network as it sees the other computers that are on it but there is no internet access. Every once in awhile it gains access and then abruptly loses it in a matter of minutes. The router supplies internet to anything else I plug into it, be it my Xbox or laptop running XP.

My desktop (windows 7 ultimate 64bit) has been able to connect fine to the internet until I got home from work this morning. My laptop is connecting to the same modem fine through wireless (along with my wii). The modem I am using is Motorola SB 901. When I rightclick my connection on my desktop and hit troubleshoot problems, I get 'local area connection 2 doesn't have a valid ip configuration'. Same thing happens when I switch the ethernet cord to local area connection 1. When I go to control panel, network and internet, network and sharing, the connection map at the top stops between my pc and the network (which is now labeled as 'unidentified network'). Here is a list of what I have done so far to try and resolve the issue:
1. Replaced the ethernet cord with one I know is working
2. Full scanned my pc for viruses
3. Disabled all firewalls and virus protection programs
4. Restored my pc to a previous save state
5. Reset winsock with cmd via these prompts: netsh winsock reset catalog and netsh int ip reset reset.log hit
6. This attempt is unfinished as I am getting stuck. I am attempting to setup a static ip to attempt to resolve the issue, but when I open cmd and type ipconfig/all, the default gateway under my local area connection is completely blank.Here is what comes up with ipconfig/all:
C:UsersPaul>ipconfig/all
Windows IP Configuration
Host Name . . . . . . . . . . . . : Paul-PC
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid

My mom's laptop is detecting that our wireless internet connection is active, but it won't actually connect to the internet. When we troubleshoot the issue, it says that our diagnostic policy service isn't running. Since we can't connect to the internet on the laptop, we can't run any updates or perform any virus scans. We've tried manually adding a network service through cmd.exe, and uninstalling the network adapters and restarting the computer. We've also tried to run a system file check, but it doesn't seem to activate. The sfc box just disappears when we try to initiate a scan. I imagine we might have to back up her important files and just reinstall the operating system, but her laptop came with a preinstalled OS, and no discs.
