Can't Connect To Home Network / Windows Unable To Find Certificate?

Jan 5, 2013

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.

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

D-Link DIR-615 :: Windows Can't Find Certificate To Log Into The Network

Aug 27, 2011

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.

Unable To Connect To Home Network Over VPN From Samsung Galaxy S3

Feb 22, 2013

I am unable to connect to my home network over VPN from my Samsung Galaxy S3 phone. I have a Netgear WGR614v01 wireless router. This router has my desktop computer and windows 2012 server plugged into it. The server is a domain controller that has the following roles installed: DHCP, DNS, ADDS, IIS, and Remote Access. My Windows 7 Professional desktop is joined to the domain controller. The wireless router serves my netbook, smartphones, and ipods. They do not authenticate with the DC but do get a DHCP ip address from the server.I have my Samsung Galaxy S3 phone that I'd like to be able to use to VPN into my network. Here is what I have done;Disabled the DHCP service on the router. Setup port forwarding to forward PPTP to my server's static IP address on port 1723.I created a user on my DC for this purpose and enabled the account for network dialup service.I created a DHCP Relay Agent in the Remote Access MMC.I opened up the Remote Access app on the server's firewall.On my phone I setup a 'New VPN Connection...' I use the username/password of the user I created for this purpose. I put in my ip address that I have from my ISP.

Home Network :: Windows XP Cannot Connect To Secure WAP

Feb 28, 2012

My laptop suddenly stopped being able to conect to my home wifi router. It stays at "waiting for network to be ready" while at the back the wifi list stays at "acquiring network adress" for a couple of minutes and then resets to regular disconnected status. All my other wireless gadgets at home can connect with no problem whatsoever.Wifi strength is great and, when disabling security, the laptop connects without a hitch and very quickly. I tried all possible security combinations the router can give me, always using a second wifi device to check if connection and browsing was possible.I tried everything I googled: drivers, firmwares, ipconfig reset renew, started and stopped services, to no avail.

Windows 7 64 Bit Can't Connect To Home Network Printer?

Apr 5, 2011

I just installed Win 7 pro 64 bit on a new computer / hard drive. I can connect to my router which is hardwired to a computer running Win XP Pro 32 bit, but I can't figure out how to connect to my printer which is on that same network. I can access the internet, just not the printer - which is connected via Ethernet to the router.Is is possible that because Win7 is 64bit and the other computers on the network are 32 bit running XPpro - that it won't work? I have another XP pro computer that is connected via wireless that accesses the printer just fine.I have a netgear USB adapter on both the WinXP computer and also the Win7.Win7 is foreign to me. I can't find anywhere where I would 'join' the mshome network. It asks me about them joining ME.

Linksys Wireless Router :: WRTP54G - Unable To Connect Home Network?

Jul 2, 2006

I recently installed a new router - WRTP54G . I used to have our 2 machines on a home network. However, that is all gone now. When I open My Network Places on my pc, nothing at all appears. On the other pc only the shared folders on that pc appears. I've tried running the network wizard several times and to no avail. I've checked the permissions and everything else I can think of, but it still doesn't work. I believe it is probably something simple to fix, like checking the right box, but I haven't found it yet. Both machines are running XP Home and I have an external drive attached to my pc. Everything worked fine till the installation of this new router. Should I just create a new network? Would that just be easier? One more thing, I got the error that says Home is not accessible. You might not have permission to use this network resource. Contact admin of this server to find out if you have access permission. The network path was not found. Of course, I am the admin.

Linksys Wireless Router :: WRT160N Unable To Connect Ipad3 To Home Network

Dec 12, 2012

I am unable to connect my Ipad3 to my home network (WRT160N router). It has been working for the last 8 months, and stopped working after I installed Direct TV App on Ipad..It detects the network, but not accepts the PW.... I have multiple wireless devicess connected to my network without any problems..The funny thing is that my neighbor brings his ipad to my house and he is able to connect..My ipad connects to any other network...just not my home network.. I contacted Apple who spend hours with me on the phone and suggested doing a full reset on the ipad, but still did not solve the problem..I called and already paid for linksys support ($62.95) who spend hours with me on the phone, but suggesting: "maybe you need to buy another router"...REALLY!!!! Again, I have 3 Smart TVs, Xbox360, and Wii, that are connected to the network just fine .even my neibor comes with his Ipad3 and connects to my network just fine......and I can connect with my ipad to any other network without any problems... BTW, I have already removed the DirectTV app from the ipad....but I still cannot connect to my network..

Windows Was Unable To Connect To Network Name?

Dec 25, 2012

Moved into a new place recently, internet has been working fine until earlier today I closed my laptop and went to make something to eat. When I came back and turned my computer back on, it keeps giving me this message when I try to connect. It doesnt ask for a password, it simply tries to connect for a few seconds before giving up. After waiting a few hours for the problem to fix itself, one of my flatmates got home and told me they are having the same issue. I have tried restarting my computer, turning off my firewall and restarting the modem.

Netgear Router (DGN1000) Unable To Connect Wirelessly To Secured Or Unsecured Home Network

Feb 15, 2012

I'll try and keep this brief, we were having problems with our netgear router (DGN1000) mainly with connection when online gaming with PS3, generally poor connection - so purchased a TP-Link router (TD-W8960N). We could usually access the netgear wirelessly on our laptops Dell and Acer Aspire 4820T (both Windows 7) without any problems and were still doing so last night. However hubby attempted to install the new router last night and all seemed to go fine but after installing we couldn't connect to the wireless network through laptops, iphone ps3 etc - even though we could see the network with excellent strength, after hours of trying called TP-Link they went through everything they could think of and still no joy. Gave up in the end and went to reinstall the netgear Router and now we have the same problem with this router, even though earlier in the night it wasn't a problem - we deleted the previous networks so there was nothing stored in memory & tried everything we can think of (although neither of us are brilliant with IT we do usually get by).We even set up an unsecured wireless network (on both routers) and still couldn't connect?

Windows Is Unable To Connect To The Selected Network

Oct 9, 2011

Windows is unable to connect to the selected network." The network may no longer be in range. refresh the list of available networks and try to connect again." Your in range of the network (right in the same room as the wireless access point). And when you refresh the list, the network still shows up there.It seems that it will only connect to Routers which use WEP security and not ones which use WPA. I have looked on the Toshiba site for the Wireless Drivers to see if there is any updated ones and used the Driver Update Utility on Intel's download site and that tells me that the latest wireless driver is installed.

D-Link DIR-825 :: Windows Is Unable To Connect To Your Network

Mar 6, 2013

I recently purchased a DIR-815 D-Link router.  I've set up my network successfully; my laptop and smart phone are easily able to connect.  However my desktop is having issues.  My network card detects the wireless network I have set up, however the password is always rejected.  I am typing in the correct password.  I can get the internet to work on my desktop if I connect the router directly by wire, but I need the wireless to work.  My desktop runs Windows 7.

Linksys Access Point :: WRT54G - Unable To Find Access Point In Home Network

Aug 29, 2009

I just bought an LG Bluray DVD player (BD390) which is unable to find the access point in my home network.My router is a WRT54G, ver. 2.2, running firmware: Ver.4.21.1.  My home network uses high speed cable with two computers on the wireless network, all working with no problems.The router is on the second floor but the two computers and the new BD390 are on the first floor - about 35 feet away. I have the wirelss security set to none and use only the specific computer MAC addresses to allow connection to this network.
 
I found directions in the forum for a setup using the LG BD390  but with a different Linksys router. I changed the security to WPA (AES); the Beacon interval from 100 to 75; the Fragmentation Threshold from 2346 to 2304; and the RTS Threshold  from 2347 to 2307. The DVD wireless connection still failed to find my network. There is a "Push button" connection feature on the BD390 setup which I tried, but the only "button" on the router I could find was in the basic wireless setting, a green icon for the wireless SSID setup. No connection was made there either.
 
The recommendation connection from the LG manual is for a network cable, but that would be over 50 feet and a real pain to connect, so I would prefer WiFi.

Windows Vista Home Basic SP1 Cannot Find Any Networks

Sep 13, 2011

I am running 32 bit Vista Home Basic SP1.I cannot get online. When I hover the mouse over the network icon in the notification area, it reads, "Connection status unknown. The dependency service or group failed to start". When I try to diagnose the problem, I can't because the Diagnostics Policy Service is not running. When I try to Start the service, access is denied (Error 5). Same scenario for the service DHCP Client. When I click on Start/Connect To - I get the msg Windows Cannot Find Any Networks Meanwhile, I keep getting warnings that my firewall is not enabled. When I try to enable it, I get a message that the Security Center can't turn it on.

Windows Firewall is not listed in services.msc.I ran a full Malwarebytes scan and it found nothing wrong. I did a system restore to several days before the problem, but even though the restore completed successfully, it didn't change my (non)results.The Network and Sharing Center does not display the familiar PC monitor icon with a line to the Network and another line going from the Network to the Internet. Instead it just has the word Unknown with the caption the depencency or groiup failed to start I have heard that this might be due to a permissions issue, but when I use regedit and navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices and right click on Dhcp, select Permissions, I get an error when I try to add anything (either Local Service or Network Service).

The msg is c:Windowssystem32adsldp.dll is either not designed to run on Windows or it contains an error. Try installing the program again..I have run sfc /scannow as well as chkdsk /f. Scannow reported that it found some problems but was unable to fix all of them. Chkdsk found and corrected about 10 errors, but neither of these programs worked with the issue.Additionally I have downloaded and installed Process Monitor on the PC, but the amount of information displayed is overwhelming, and I'm not sure what to check. Every time I try to start DHCP I get about 200 lines of info on the screen.

When I open a command prompt and run ipconfig /all, I get that DHCP is running, although it is not. I get the bogus ip address of 169.254.... I get a default gateway of zeroes.Is it possible that this behavior could simply be the result of a bad NIC card?Can I possibly run an in-place upgrade from Vista Home Basic to Vista Home Premium? If it's a Dell PC and I have the Dell Premium CD will it ask me for the product key? If so, will the key on the Basic PC work?

Home Network :: Unable To Get Home Networking

Oct 16, 2011

After trying most things and spending money like water, I still cannot get our home network to be adequate and I am out of options - Tried using two 100MBit/s Netgear routers "bouncing" signal to each other (Wireless Repeating Function). Not ideal as security is small and speed was slow (<10MBit/s) but at least it worked. However these routers had to get pensioned off when we put gigabit ethernet in the office - and the Netgear replacements (a) still have the security limitations with wireless repeating, (b) anyway see to do a worse job of repeating. Tried buying Netgear directional high-gain antennas and directing the signal point to point to a second router - didn't work at all. Tried Powerline (this was in 2008). It sort-of worked but was unreliable and dog slow. I think this is probably not worked by the fact that this building is OLD, most of the wiring is OLD, and anyway the electrical path would take the signal from the 4th floor, down some very old wiring to the ground floor, across a very old switchboard, and back up to the second floor... it's not quite the same as a modern house with modern wiring. Most recently tried using Netgear's Wireless Network Extender. Again, it sort of works, but it's NOT fast at all. In addition there are times when some of our computers using the extension segment of the network are unable to connect - they can still see 3-4 bars of signal, but they cannot get on the network. Appears to be an issue relating to gateway, or DNS, not sure. But I would say about 1 day in 3, when I come home, my wife tells me that the "internet is off".

Unable To Find Wifi Networks On Windows 7 Acer 3810t

May 9, 2011

I have an Acer 3810T laptop and am running Windows 7 on it.The problem I've had is my WiFi has been unstable. For example for 5 minutes or sometimes up to an hour I can easily find wifi networks in range of my laptop but then out of nowhere it disappears and I don't find any networks but any other WiFi device will find my router so I know it's laptop related.I did some research on Google and found out this is an issue others have had with Windows 7 and it seems to be something to do with when updates are installed. I followed the advice to remove my WiFi drivers and reinstall them so I downloaded a file for the Intel drivers from Acer's website. I went into Control Panel and removed 2 devices that were related to WiFi. I then did a scan for hardware and found one wifi device, an Intel WiFI Link 5100AGN. I installed the driver for this one. The problem is I know I removed two and this is the only one the scan found and I can't remember the name of the other wifi device/driver I removed.Unfortunately ever since I did this my WiFi isn't working. In the control panel it shows all drivers are installed and working but when I click on the bars at the bottom of my screen no wifi networks show. I have tried going into the Network and Sharing Center and for example I select set up a connection or network and when I select Manually Connect to a wireless network it states "An Unexpected Error Occured" so I know something is missing that's allowing the WiFI to work.

Home Network :: PCs On Modem Can't Find PCs On Router?

Oct 3, 2011

I have a wireless modem on the first floor of my house, where I got cables through the wall running throughout rooms in first floor, ground floor and basement.I have my small business at the basement, so I have 2 PCs one printer and one external hard disc which also connects directly to a modem/router.I have 3 PCs from the first and ground floor that connect through the wall to my modem, and everything works well. But for my basement, which only has 1 lan cable output on the wall, I got myself a router so that I can connect all my devices.I connect the router with my modem, and then the PCs, printer and hard disc on the router. The PCs have internet access, so I know the connection to the modem has nothing wrong to it. But I am not able to access the PCs connected to the router from the PCs connected to the modem, or vice versa.

I was told to not obtain an IP address automatically, so I assigned my modem and router to work on 192.168.10.x and gave my PCs IPs such as 192.168.10.19 Only after setting this up did all my PCs have internet access, but again, no network communication between PCs on modem and PCs on router.One thing that might be worth mentioning, is that through time, my network keeps going from Home Network: Network, to Network 2, Network 3, and so on... now it's on Network 5. I have no clue why this happens, and if it's related to my problem
