Search Windows Cannot Find A Certificate To Log On To Network?
Jan 25, 2011
"Can't find certificate-wireless". I've applied all the suggestions. With and with out Winduh Zero Config and network adapter software. Unchecked 802.1x, changed ecryption types, modem and computer reboots, push little button on back of modem, tried two differnt makes of network adapters, confirmed correct network key typed, etc. All these things in many combinations. Great full signal, no certificate or with software installed no connectivity. Is it time to Ethernet hard wire my network? Is it the Windstream 1704 modem? Studied and tweaked the modem settings a little

My DIR-615 was working for months but then it unexpectedly stopped. So I tried re-linking, but Windows can't find the certificate to log onto the network. I found the network fine but I can't find anything that lets me input the WEP key.
Perhaps I need to reset it up on the main computer? But I don't know how to find the IP address or the MAC address.

I just got back from vacation and suddenly can't connect to my Wifi network at home with my netbook anymore. It says validating identity but never connects. When I try to repair the connection, it keeps authenticating and then says that windows is unable to find a certificate to log me on to the network. I did some googling and it was suggested to uncheck the Enable IEEE 802.1x authentication for this network box under the Authentication tab in Wireless Network properties. I tried that but then I get an error message saying "The network password needs to be 40bits or 104bits depending on your network configuration".I have no idea what to do or what the problem is. My other laptop works fine from which I have set up this network works fine. My phone seems to work fine, too. I already restarted the router and my netbook but that didn't work either.

I have a small business network computers w/a linux server. One computer was infected with viruses which I removed via kaspersky/norton/malware anti-bytes. I run windows xp professional on this computer.However I run into the following problem:
1) In my network places the documents on the server do not show as a network place-this is despite me being able to access these documents via a folder shortcut
2) After I open the network files/folders from the comp, I am unable to use the find feature because the folder is not listed under the look in drop box. I tried changing workgroups and ran into the same problem.

I've been wrestling with a Windows XP reinstall that wiped out my network adapter. Fortunately I found D-Link AirPlus Utility and have restored it. However, now it says that windows was unable to find a certificate to log me on to the network, although I have entered the correct key.

Since I updated a Catalyst 2960 switch to IOS version 12.2(55)SE1 I can't do searchs by MAC address, when I do "Monitor->Search" the following error appears:"The software version of the selected switch does not support some of the CLI commands in read-only mode for this window. You must have read-write access to this switch to display complete information in this window" If packets are captured you can see that the issued command by the CNA host is "GET /exec/show/mac-address-table/", the answer from the switch is:"show mac-address-table ^% Invalid input detected at '^' marker.
If I do "Configure->Switching->MAC Address" instead I get the mac address-table correctly. In this case the issued command is "GET /exec/show/mac/address-table/dynamic" and no error is displayed, the answer from the switch is the list of mac-address table.

my computer has been playing up the last couple of weeks not finding my network, even though ive had it about a year now without any trouble before. my laptop and iphone still pick up the wifi with no problems.i decided to format the computer as i wanted to do a clean install anyway, which has not made any difference. i have even tried bringing the desktop downstairs now and placed it directly next the the router to see if it would pick it up then, which it hasnt.
i have used an edimax wireless usb receiver ever since the computer was new which worked fine up until now, i also purchased a wireless pci card to see if that worked (wasnt sure if my my edimax usb had broken), which still doesnt work. the drivers for both the pci card and the usb receiver are up to date.i have tried logging into the routers firmware and changed the channel from 'auto' to channels 1-12. with no luck. i have now had to plug my computer into the router via the ethernet port to get the internet working.
i also run ubuntu on a dual boot, which for some reason also doesn't pick up the wireless network. (however my laptop runs ubuntu and does pick up the wifi)

I have a dell, running windows 7. I can see and connect to other networks, just not my work network. I can see my work network and connect to it from other devices. However I can't see it on the dell and I can't manually connect to it.

I just got myself a new laptop, and set it up. It is connected to the wireless internet in my home. I then wanted to create a homegroup between the laptop and my desktop, but they can't find each other. Probably because the desktop has a wired connection to the router and the laptop is connected to a wireless access point. The router and the AP are connected to a switch in the middle by cable.
A sketch of the network:
Laptop - - - Wireless Access Point ----- Switch ----- Router ----- Desktop
^ ^ ^ ^
Wireless Wired Wired Wired
They both point to the same gateway and DHCP-server (on 192.168.0.1). And I can ping to that address from both PCs. When I try to ping either of the PCs the pings time out. The subnets are also the same (255.255.255.0) and the IPs are in the same range (192.168.0.114 laptop, 192.168.0.205 desktop).
So I don't really understand what I need to do to be able to access either computer from the other. The weird thing is that Synergy (to use mouse and keyboard over the network) works, just by using the IPs assigned to both PCs.
The acces point is a linksys WAP54g, but I'm unsure of the Router, it has a custom casing from our ISP and hides any clues for identifying the product. I'm going to google a bit so I can add that info later. Both PC's are Windows 7 64 bit. The desktop is Ultimate, the laptop Professional.

I went to Furrynutz link where I never found the direct download lilnk to the widget. I then chatted with a Microsoft representative at the widget page and he linked me to the same Furrynutz's link.
My DIR-825 has the latest firmware, 2.06xx and works flawlessly, even the shareport usb port works without a hitch with a Seagate Expansion 3TB drive connected into it. What I simply would like is the D-Link gadget.

Well one day i went onto my gaming PC and started playing, it randomly restarted and did some random windows check while starting. Then when i finally logged on i had no internet connection, my computer didnt sense there being a cable plugged in (Wired connection. The orange light wasn't on) So i figured i should just reinstall windows anyway (Blue screens, ect) After i reinstall i have the same issues. I have moved it to a different room and still the same thing. If i can't fix it then i plan to just buy a USB wireless but i would like to see what others think what i should do before i go making hasty decisions.
The computer say "Windows could not find a driver for your network adapter" I have tried many things i have found on this forum and nothing. So maybe a link to a driver? my Router is a Linksys WRT54GL and has always worked.

I am passing my computer on to a family member and wanted to give them a fresh install, so I used the Windows Vista (32-bit SP1) disc that came with the laptop and reinstalled Vista on the computer. Everything worked fine until I wanted to connect to the internet, then Windows said that there were no networks available. When I selected "Why can't windows find any networks" it said that "This computer does not have a wireless network adapter installed and configured". I put in the Dell Driver's and Utilities CD that came with the computer and installed the drivers that seemed related to networks or communications, but the problem persists. I'm assuming it is some sort of driver issue (as the computer was using wireless internet before the reformat (just hours ago) and so the device itself seems to be working.

I've just bought a WUSB300N Wireless USB Network Adapter and installed it with the Vista drivers on my Windows 2008 server. Drivers are succesfully installed and the Device status says "Device is working properly" but when I want to connect to a network it doesnot show any networks. I'm sure there are network available because I'm connected now on my other laptop ;-) typing this message.

We use a combination of Cisco ACS and Cisco catalyst 3560 switches for network authentication and authorization. Clients (Windows XP) have a certificate installed which will grand access to the network and put them in the correct VLAN. So far, so good. Some users are testing with Windows 7 in the same set-up as above and run into strange behaviour. The problem is that after a random timer the machine gets de-authenticated and nothing besides a reboot works to get the computer authenticated again (from a Windows point of view). It looks like this only happens to users who are using a certificate to authenticate, Windows 7 MAC bypass users have no such problems. If it occurs, the following logging appears in ACS: [code] We are using ACS 4.2(0) Build 124 and 3560-48PS switches with IOS 12.2(55).

There is ASA with remote access VPN and users are authenticated using third party signed certificates (CA is not local in ASA).When user certificate expires i can see it in syslog messages. For example:
%ASA-3-717009: Certificate validation failed. Certificate date is out-of-range, serial number: (...)
I would like to know if there is an opportunity to view user's certificate expiry date beforehand, say, 3 days before?

We are deploying BYOD with Cisco ISE 1.1.2 and WLC (5508) using 802.1x authentication.Windows clients cannot connect to 802.1x SSID with the following error on ISE:Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
The client doesn't have preconfigured wifi profile or root certificate installed.The concept of BYOD suppose that you can connect your device without any installed certificates and preconfigured wifi-profiles.
The problem is that Windows 7 supplicant does not send TLS alert in pop up window, when connecting to 802.1x SSID.If this alert is seen, than you can accept it and proceed the connection. After that you will be asked to install ROOT-cert, get your own cert and etc.So, the question is: how to make the windows supplicant to show the pop-up window with TLS alert?
p.s. the attached file shows the example of pop up TLS-alert window

Digital certificate on the ACS Wireless network:
Checking the configuration of the Wireless Notebook no longer requires the digital certificate of the ACS and NVR122 NVR123as worked in the past. The certificate is generated for the ACS root CA trusted by the COMPANY, so that the public CA certificate supersedes theprevious ACS. Therefore, any host that is in the field of company would have access to the wireless network. With this, the 8021x is working with a certificate that is common to all hosts in the field of business. How do I change it?
