Unable To Detect Any Networks After Reinstalling Windows 7?
Feb 17, 2012
i just formatted and reinstalled windows 7. wireless internet was working perfectly fine before, however after reinstalling windows 7 my bluetooth network adapter is not able to detect any signals. i attempted troubleshooting and it said to connect a ethernet cable. i did notice in device manager in "other devices" theres a device "network controller" that isn't installed. i'm not able to cuz i can't access the internet with that laptop.

For the past few weeks I have been having problems with my HP laptop.
For starters my laptop will not restart. I try to restart it and it shuts down, but won't reboot all of the way. It gets stuck on the black screen you get just before the HP sceens comes up. So I have to press the power button ( after which I do, I get a loud POP sound before the computer shuts off ) and then turn it on again myself. Also, if my computer goes in to sleep mode due to inactivity, it will not wake up. I have to press the power button to turn it off, and then start it up again.
After this happens, my laptop cannot detect any networks. I have to unplug the charger, and then I have to take out the battery and put it back in before it detects networks.
I took it to best buy ( where I bought the computer and have a warranty at ) and they did a diagnostic test and determined that I had several viruses causing the problems. After paying 200 bucks they ''fixed'' my computer and I brought it home, only to have the same exact problems I was having before.

I recently moved a work computer to my home to use in my home office and i now can't connect to the Internet. I have the computer directly connected to my wireless router through an Ethernet cord. All other computers that are connected wirelessly seem to work absolutely fine. When i open up network and sharing center and try and run the troubleshoot problems I constantly get the following error message "windows could not automatically detect this networks proxy settings".

I recently bought a TP-LINK TL-WN350GD wireless network card, inserted it into a PCI-E slot and installed the drivers, but can't seem to get it to work. It appears in Device Manager as 'Atheros AR5007G Wireless Network Adapter' and apparently 'this device is working properly', but infuriatingly it won't detect any wireless networks. I've tried using the drivers that Windows 7 installed automatically and also the drivers that came on the disk with it, but all to no avail. When I troubleshoot the card, I get the message that 'there might be a problem with the driver for the Wireless Network Connection 2 adapter', but this is all I can find. It's especially irritating as I picked the (admittedly lower-end) card because it's definitely compatible with Windows 7 (I already tried one which wasn't).My PC has Windows 7 64-bit, has an AMD Athlon 4600 dual core CPU and 2 gigs of RAM.

I've been searching through some threads but I can't seem to find the answer to my problem.. Or I'm just dense.I just downloaded Windows 7 and I can connect to the internet with my ethernet cord but not using wireless. Before I downloaded 7 I could connect easily with Vista and had no problem detecting wireless networks..

brand new lappy. its the Acer travelmate 5740G fantastic specs - everything is nice and responsive, except that i can't connect my wireless at uni. the tech guy had a look at it and he can't figure it out either. we did everything, including shutting down (eventually deleting) the AV because of its firewall. we set up the network exactly as everyone else does (and it works for everyone else).
the computer keeps suggesting that we check the router (but the router works). i can get net through RJ45 no worries but... i want my wireless to work.

I did a fresh install of windows 7 ultimate I was really just uping it to the 64bit beause I accidentally installed the 32 bit. So after doing all of this Windows 7 is working fine however upon boot up where normally I would have the option to choose which OS I wanted to start up, it just goes straight to windows instead of giving me an option. I had the latest version of Ubuntu, and I know that when I installed widows I put it on the right partition of my C: drive. Do I need to know reinstall Ubuntu as well or is there some kind of setting I have to change to get it to show me the OS selecting screen.

Since a while ago, I tried to connect my laptop to any wireless network available around my neighborhood, but I couldn't find any. I tried connecting with a DSL cable from my friend's Pc, but I couldn't connect to the internet. So i tried setting up a "Dial-up Connection" , I followed the instructions, i restarted my laptop, but didn't work either because I needed a password and username from the internet provider. After that, I tried to look for other people's wireless networks again, but this box appeared:"Not connected. No connections are available" I used the troubleshoot option at the bottom, but it said "Troubleshooting couldn't identify the problem". I tried turning off my Windows Firewall ("Home or work (private) networks" and "Public Networks"), but the problem is still going on.

I previously bought a used laptop running Win 7 Ultimate which I am the administrator and for ages I have wondered why I am always unable to connect to adhoc wireless networks, connecting to wireless access points have no issue though.Connecting to adhoc networks always gives me the 'your network administrator has blocked you from connecting to this network' message. I recently found out, as below there seems to be a group policy set in place?Can anyone show me how I can disable this policy please, without having to reinstall windows 7 again as that would really be too much effort for me[CODE]

I have ASUS tablet with Windows 7. I use USB to VGA converter to connect to VGA projector. It used to work until June 4 at 5:30PM PST, when it stopped working during presentation. Before that it worked for 4 months. Looking at control panel adjusting external display if I select duplicate to projector I only get my computer display. It says it does not detect external display.

I have just installed Windows 7 onto my Dell Inspiron 6400 laptop. My laptop now detects a number of wireless networks in the vicinity but not my own. It is not a problem with my router because other laptops can pick up the connection no problem. I have Googled this problem and see a lot on issues with Windows 7 and picking up wireless signals. But I haven't seen any threads which deal specifically with the situation where only one wireless network cannot be detected.

I recently embarked on the journey of building my first custom PC. Everything was going well, until I hit a speed bump of installing Windows 7 64 bit. So like usual I boot from the CD drive, and stick Windows 7 in. When it gets to the point where I'm going to install, it is unable to find my SATA drive to install Windows 7 on.
It then asks me to "locate drivers." So it gives me an option to browse, and when it does so I put in the disk that came with my mobo, but it's unable to find any drivers. I tried downloading drivers from my motherboard's web site, sticking them on an external HD, and locating them from there, but that still didn't work.
I checked in my BIOS, and my SATA type is under Native IDE. I tried switching it to AHCI, and my HD was no longer detected in the BIOS, switched back to Native IDE and it found it again. Also, Onchip IDE Channel is set to Disabled, and Onchip SATA Control is set to Enabled, does this matter any?
I was wondering,though, is it possible that if I set the SATA type to AHCI, move the SATA cables into ports so that the drive is recognized by my BIOS, use the AHCI drivers I downloaded, Windows 7 will detect it?

my connection to my work's wireless network was fine.
Last night, I installed driver software for my network card for my Ubuntu OS (dual-boot machine). Ubuntu and W7 are on separate partitions; I am not running Ubuntu inside of Windows. This morning when I came into work and booted into windows, it did not connect to the network. I have already updated the driver software through device manager (I already had the most current driver installed) and have downloaded the correct drivers from Dell's website.
I have also done a system restore to prior to last night's Ubuntu driver update. And that didn't work. At this point, I am connected via cable, but if I remove it, my wireless card will not see our wireless network. I have tried to manually create our network through the "Set up a new connection or network" with the correct SSID and security code, but that did not work either.
How could my work on the Ubuntu side have affected the performance of my network card or settings on my Windows 7 side? I can connect to a wireless network in Windows?

I turned on my Windows 7 comp yesterday and my wired (into the ADSL wireless router) local area connection is stating its unidentified.
1. Hard Reset the Router and Modem
2. Tried installing new protocols through the adaptor settings.
3. Tried updating the realtek drivers
4. Tried uninstalling the LAN and reinstalling
5. Tried stopping and starting Bonjour.
6. I added a USB wireless dongle and this ALSO says it is an unidentified network.

Windows 7 does not remember/save wireless networks even though I check "connect automatically" when I connect. In the Manage Wireless Networks control panel ONLY the current wireless network I connected to is ever listed. If I connect to another wireless network then that previous network is gone from the list.
P.S. - I'm running Windows 7 Professional 64-bit

In this tutorial I will show you how to detect wireless networks in Windows 7 and how to connect to them. As you will see, the procedure is very simple and requires very few steps. On the right side of the taskbar, you will see a wireless network icon like the one below. Click on it.

My problem is that I work in a school and we have bought 22x Samsung N145 Plus Netbooks. They use Atheros AR9285 wireless cards and I'm having problems connecting them successfully under Windows 7 to my D-Link access point. The fact is that the security has been set to WPA, using AES. The laptops are the same and are connecting, but 9 times out of 10 they pick up an autoconfiguration IP of 169.x.x.x.I sometimes get one working, but never have more than one connect at the same time. I need it to just pick up my 'chads.internal' domain network but it rarely does it successfully. I've tried adding the settings manually, I've tried 3 different network card drivers for WLAN (latest out from the Atheros homepage, second latest as requested to be tried by Samsung tech support, and a version 8.x.x.x driver after reading that 9.x.x.x drivers are 'flaky'), 2 different wireless access points, and the next step that I'm trying is to see if Windows XP will connect!!! I really don't want to have to go down that route!

I've been fiddling like mad for a couple of days now with a new Win7 Ultimate x64 machine "desktop", and using an old XP Pro machine as a fileserver, the last few hours getting the XP machine, which is rather old, to respond to Wake On LAN. I've been trying to track down why the DSL router is triggering it from standby mode, so I swapped to an older router than my usual one to see if it causes the same problem.Suddenly, the Win7 machine has decided it's found a "new network" and called it the exciting moniker "network 3". I don't want a new network. I am quite happy with the old one. I cannot find anywhere in the baffling wizards etc to tell it which network I am on. It just seems to be an arbitrary decision by Win 7. It seemed to happen a while after I unplugged the DSL side of the router from the phone line, to see if it was stuff coming in from the internet waking the server, but it didn't happen immediately, so I have no idea why Win 7 suddenly decided it had found a "new" network. All the IP addresses (static) are the same, etc.
Every version of Windows seems to get more opaque and designed to prevent anyone getting "under the hood" to see what is actually going on. How do I get under the hood to delete this network that I do not want that is precisely the same computers as the old one? If I plug in another different router some time, do I get yet another "new" network? Is there somewhere I can delete these networks? From the command line perhaps? I can find a "set up a new network" link in the Network And Sharing Center, but "get rid of this one you didn't want" doesn't seem to appear, for some reason.

Hidden wireless networks are those networks which do not broadcast their Network ID (SSID). While not that many people use such networks, it definitely ads a bit more security to have your home wireless network hidden from unwanted guests. In this guide I will share with you what details you need to know in order to connect to such networks and what are the steps for making a successful connection.

Why does it say "Connected" next to "Public Networks" in my Windows Firewall page when in fact my computer does not show it is connected to any network at all? Why is Windows Firewall telling me I am connected but all the other relevant notifications in my computer say that I am not connected?
Even when I disable all my network connections and turn off Windows Firewall, the Windows Firewall page still says I am "Connected".
(This is on a brand new computer -- just a few days old -- with Windows 7, 64-bit.)

I had a network with 2x Win Vista PC's, 1x Win XP PC, and a shared printer. I replaced the Win XP PC with a new Win 7 PC. Now the 2x Win Vista PC are on separate networks: Network 2 & Network 3. The Vista Network 2 PC can no longer see or use the printer, which is cable attached to the Network 3 Vista PC. Seems like the Win 7 installed new, separate networks for the existing Vista PC's. The network hardware is: Comcast modem > Dynex router > Cisco ethernet switch > 3 PC's. I did not change any network connections, hardware or software on the Vista PC's. I simply removed the Win XP PC, and replaced it with Win 7 PC on that network cable.

I am having a wireless issue on my laptop. I have had my connections in the two locations for months now. One network was recently upgraded to another router and the other network router was reset. I am at the location where the router was reset. My available networks are showing and are in excellent strength but whenever I hit "connect",nothing happens.I don't even get a prompt to enter the passcode. I even tried to connect at my local library's wifi with no such luck. When I run diagnostics it keeps saying "None of the networks you have previously connected to are in range"?? My drivers are up to date. I am a novice when it comes to computers so I really need help on this one. Just tell me what is needed in terms that I can understand (again, I am not that computer savvy,lol) and I will provide them. I am running on a 32bit and my laptop is a HP. The router is a Broadcom 4313 802.11b/g/n

I have a Lenovo ThinkPad laptop, with Windows 7 home x64. As soon as I turn my computer on and the system finds available connections, the system connects itself automatically to the first WiFi network it finds. Usually this would be my home network, which is fine. But occasionally, this would be my neighbor's unprotected network, which is not as fine.
Potentially, this could be a malicious network, monitoring my internet traffic, which is not fine at all. A possible solution might be to check upon system start that the correct network is used. However, if the connection is accidentally broken, for whatever reason, the system again connects itself to the next available network, which is again problematic. How can I stop this automatic WiFi connections?

I have an Acer laptop windows 7, but Just recently (yesterday) a problem came up that at first I thought it was the modem but now I see the problem is my laptop. And basically when I run the windows network Diagnostics 3 problems come up:
1. None of the networks you have previously connected to are in range,
2. Problem with wireless adapter or access point, and
3. The default gateway is not available.
So I am not sure what to do?

I bought a brand new Samsung QX411 two months ago. It's a great computer. Problem is, it got hit with a nasty virus that was pretty much completely debilitating, so I took it in to Best Buy (mistake), and they told me the best thing would be just reinstall Windows 7, and everything would be great. Well, I did, and now I am stuck. I reinstalled, but I did not realize that literally nothing would be in place. I am not completely naive: I did save all of my important files, folders, music, etc. So it's not that I have lost my data and am now crying "woe is me." Instead, I have basically a blank Windows 7 and nothing is there. I can't connect to the internet, because it is telling me that I don't have the necessary hardware (I know I do, but still). A basic summary would be this: I have no idea what to do after properly installing Windows 7. I want to get it as close back to normal as I can, but I don't know how to start.

I recently built a new computer system that contains my old HDD, which I transferred from my previous PC. The old copy of Windows 7 that was already installed didn't work in the new PC, as expected. Instead, I have a new copy of Windows 7 available that I need to get on the HDD. But I also need to deal with the old Windows copy. I've already transferred all of my personal files from the old copy onto a portable HDD for safe keeping. What I plan on doing is reinstalling the new copy of Windows 7 onto the PC's HDD to be used in the new computer. I was able to acquire the new Windows 7 version for a really cheap price from my college.
So now I either have to format my HDD so that the new Windows 7 can work properly while keeping the old/useless version out of the way, or wipe the old Windows 7 from the HDD completely. Should I keep the old Windows 7 on the HDD and just never use it, or would that conflict too much with the partition used by the new version? If they do conflict, how should I go about removing the old Windows 7 partition? dealing with the HDD and OS seems to be one of the most annoying parts of a PC.
