Can't Connect To Wpa-psk Encrypted Networks
Aug 27, 2009
I've got a problem with Windows 7 Ultimate RTM and wireless LAN on my Lenovo 3000 N200 Notebook with Intel 3945abg wireless chip.I can't connect to wpa-psk encrypted networks although I installed the newest driver from Intel and tried an older version, too. The network adapter is installed correct in the device manager.If i use no encryption or WEP there is no problem, but i must use WPA-PSK.The network settings on my notebook and on the access point are 100% correct, and it worked fine with Windows Vista and the same hardware.

I have gone through most of the posts on this forum that talk about Networks and Connectivity, Homegroups connections, and nothing addresses this problem.
I have had Homegroup established on both my desktop and on my notebook both running Windows 7 ultimate build 7100 for months. Surprisingly; few days ago, my notebook ceased to see the Homegroup and my Network and Sharing Center says that the notebook is currently not connected to any network even though the notebook is connected to the network and can use the Internet.
Homegroup and public group and unidentified group all disappeared on my notebook but working well on my desktop. I have done all the suggestions on other posts (i.e. leave Homegroup reboot, establish new one, passwords) you name it, I tried them all. The groups do not show as you can see in the attached picture. I tried IPv6, I tried the Homegroup listener in the Services. I tried about everything.
Both desktop and notebook connect to my ADSL router wifi.
Has anyone been through this problem? Greatly appreciate your input.
- Edit: I found out that the PNRP service is disabled, normal, but it will not start, when I start it I receive "Access Denied" error. Any suggestions?
- Problem Fixed: I reinstalled Windows 7.

I am running an hp g4 notebook with windows 7 64 bit. I can connect to my home network just fine, but I am unable to connect to any public network. The networks show that the connections are available, but when I try to connect I either get a cannot connect error or connected but with no internet error. I have updated the driver for my wireless adapter (Broadcom 4313GN 802.11b/g/n 1x1 wi-fi) and tried resetting the winsock, dv4 and dv6 in ipconfig. No luck with either. The networks show as open.

I want to know if it's possible to use a USB wireless modem and at the same time be connected to a wireless router with the result of increasing my internet speed. I have them both connected at the moment but it seems like only the USB modem is being used. How can I set up my laptop so that it uses them both and makes my connection faster?

Running Windows 7 Ultimate 32bit hereAm unable to connect to any NEW Wifi Networks that are detected.The WiFi Adapter sees them just fine - just cannot connect to them.However am able to connect to existing networks (SSIDs that already appear in "Manage Wireless Networks").Furthermore, If I boot into my Windows 7 Enterprise for work, everything works good.For example:I have a saved WiFi connection for my Verizon Hotspot device, that I can always connect to.But if am at hotel (no encryption), and want to connect to their wireless, It fails to connect.

Went to the city library today - laptop wouldn't connect to any unsecured network. The library does not offer wifi, but you can detect 4-5 several unsecured networks nearby. I wasn't able to connect to any of them. One of them said "Public" - not sure who it belonged to - but the icon beside it was not the typical signal bars. Couldn't tell what it was - looked like maybe a LAN connection, three entities connected to each other. Haven't seen that in the network list before. I could connect to that one, but after a minute or so the connection was dropped.
I've never had a problem connecting to unsecured networks. In fact, I packed up from the dud library and went up the road to a neighboring town library and connected to their unsecured network just fine.
Any ideas why this happens?

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.

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.

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 been having this problem for 2 days now. My computer was working fine, and I went to go do something, so I shut my laptops lid to put it to sleep. I came back about 5-10 minutes later, and it had a red cross on the network button, at the bottom right of my desktop. I tried turning the Wi-Fi on/off with F2 + Fn, but that didn't work. I have checked in device manager, and everything seems to be working. My wifi card is an Intel(R) WiFi Link 5300 AGN.
Currently running this on a Dell Studio 1557, with Windows 7 Home Premium 64bit. I've had this laptop for almost 3 years now, and it has never been a an issue. I've tried restoring my laptop to a couple of days ago, but that has given me no results. I tried running the computer in safe mode with networking enabled. I enabled my wifi with the fn + f2, and I saw my wifi network. However, while it was connecting, the connection was lost again, and I'm yet to see it.
After disabling and then enabling the driver, it would show the network for about 20 seconds, then it would be missing. Now, I can't even see it at all. All my other computers/devices can see my network, and it can still connect with it's Ethernet port. This problem is really starting to be a pain, since my laptop is pretty useless if it can't have portable internet.
Background Info:
Model: Dell Studio 1557
OS: Windows 7 Home Premium 64bit
WiFi Card: Intel (R)WiFi Link 5300 AGN
Antivirus: McAfee Total Protection 2011

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'm visiting my parents for the summer and I brought my laptop with me and the wireless was working fine for the first month or so. One random day it stopped working and will not connect. I called dell support and for some reason it just started working when I was on the phone with him, but for the next couple of days it would connect for awhile then not connect 15 minutes later. It's not the router because it won't connect to other networks, the dell support guy says its not the hardware (everything in the device manager says its fine also), It works when the ethernet cable is plugged in, I installed all the latest drivers for the network adapter (Intel Wifi link 1000 BGN), I installed a registry fix program and for a little bit it was working with some networks, but only limited access.

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?

For the past few months, I have been accessing the internet with my laptop's wifi through my neighbor's password-protected network (with his permission). I also sometimes go online using another neighborhood network which does NOT have a security key.As of today, I can view networks and connect to both of these (as well as others), but I can't get online. I get the "No Internet access" message when I connect to any network.When I go to the command prompt and type ipconfig /all, I get this for IPv4 address: 192.168.1.9(Preferred) and I cannot successfully ping any ip addresses.

I would like to have encrypted IM capabilities with one person. I don't want to download files. I don't want to use servers. I don't want to use any social networks. I simply want an encrypted way of communicating as near as real-time as possible - text only.

I bought a new PC few days ago and tried to using old harddisk and OS with it and failed badly. After some unlucky tries, I bought new harddisk and installed windows 7 in it (my old OS was Windows 7 also). I also plugged old harddisk into new PC so, I have new harddisk and new OS and old hard disk and old OS in my PC. I can access my old files but when I try to copy my documents folder to new harddisk, it gives me an error like "access denied". After some research, I know it's EFS related because files are green (it means, it's encrypted). EFS, I can't access my own files, I tried to change ownership but it didn't worked for me. I also can't change encryption settings because of my old user is gone.
Simply,
- I have some files encrypted via EFS in my old hdd,
- I have all my user and windows files of my old OS (probably EFS certificate files),
- I know my old username and password.
How can I decrypt my files? Is it possible?

I encrypted a file using my other computer running Windows 7 and I just transfered it over. I try to open it, (I used TrueCrypt), and only on my laptop does it fail to open the file. I've tried opening it with TrueCrypt over and over but it doesn't register it.
I really need this file open or else I can't use the stuff in it for work.

I have a machine Running Win 7 Enterprise x64, the drive has been encrypted with BitLocker. Recently the machine stopped booting. I have tried normal boot, last known good configuration, safe mode w/ networking, safe mode and none of these will boot, they all get a BSOD.
I have the BitLocker Recovery Key so that part is not an issue. Is there a Bootable CD that has the ability to unlock the drive or does anyone have any other ideas?
