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.
I have an Acer Aspire X3950 desktop, I am running Win7 and have tried two different wifi adapters and they install but they will not connect. It is almost as if my computer itself is blocking the adapter.I spoke to an On Networks rep for over two hours and he tried everything from reinstalling to rebooting and tried three different drivers. He was from a different country and when I told him what the troubleshooter said he would not deviate from the script they give them 2 hours and he was not even close. It saw the device but it wouldn't even blink.Acers website nor customer service will assist me because my warranty is expired. They want me to send the computer back but I have a feeling it is an easy fix I just don't know enough about computers to say oh just uncheckmark this box.I know in the past I used wifi but switched to an ethernet cable.
Recently, I have found out that my laptop is unable to find any networks. I started using what I believe to be an ethernet cable to connect my laptop to the internet because it was faster than wireless. But when I removed the cable and try to connect wirelessly, the computer states that there are no wireless networks in range. I know the wireless adapter is broadcasting because my sister can connect wirelessly to the internet. My WiFi is on, but I can't find any networks.
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?
I've been having major issues with my wireless on this computer (randomly decides not to work while computers in the same room are fine) so I got a new wireless card to see what it could do. Installed it, everything says it's installed fine, but it will NOT detect any wireless networks. Not just mine, any of the 8+ networks I can usually detect from my room. I'm on Win7 Professional 64.
Things I've tried (and I'll be seriously annoyed if people reccomend doing them a 14th time, as I've already spent an hour on livechat with a support person telling me to do things I told her I'd already done):
Installed with 4 different drivers (the ones on the CD, the ones on the website, two versions directly from Ralink for the chipset) Tried both the manual and automatic "update driver" options in device manager. Uninstalled/reinstalled it like 4 times. Moved it to a new PCI slot.
Removed the old adapter before installing it. Removed the old adapter after installing it. Tried connecting to my network as a "hidden" network (which it's not). Installed only the driver and not the adapter utility, and used the utility. Installed the software before physically installing the adapter. Installed it after physically installing the adapter.
I'm at a loss. It doesn't detect ANY networks. No, it's not a problem with my network, there's more than a half dozen that my other adapter, in the same computer, can detect. And I don't know why. It has not ever worked properly. The antennae are on properly, nothing is interfering with it (though that would be odd since it's 3 inches from an adapter that can detect other networks). I might be willing to accept that it's just DoA, but that would be odd considering it installs just fine and reports that it's working just fine.
So I recently took the WMP54GS ver 1.1 wireless adapter out of my old XP computer and put it in my new Vista 64bit computer. I successfully installed the adapter, downloaded the drivers (WMP54GS-v1.1_v220.127.116.11_Vista_dr), and unzipped them on my C drive to their Linksys Driver folder. When I go to find available networks it says "Windows cannot find any additional networks," and when I try to set up a wireless network it shows a blank window and says "an unexpected error has occurred." I can see the adapter in the device manager, so it obviously installed correctly.
But I am connected to the internet somehow. There is no ethernet cord connected to my computer and the ethernet adapter is disabled. Also, when I add an SSID to my preffered networks list, it appears, but once I click OK, and bring up that same screen, it is no longer there. Yet, I am still connected to the internet. Wireless Zero Configuration is ON, The wireless adapter is ON, I am connected to the internet as I am typing this How do I get Windows to populate those two lists (the preferred wireless networks and available networks lists)?
I have tried restarting my laptop multiple times (something that usually works for me in terms of reconnecting to the internet) but that didn't work. And like i said it does not recognize a single wi-fi network while my ipod, phone, and the other computers in my household recognize our wi-fi and our usual neighbors wi-fi without any problem.I was torrentingsome music yesterday, and may or may not have stumbled across a bad site with a virus, but that's the only conclusion I could make.(Currently posting this on my brother's computer)I need to get my connection back and get online again asap?
Have a ZyXEL 600 wireless router - it has worked without issues for years.However yesterday evening my wireless router suddenly stopped broadcasting a signal. 2 different PC's and a wifi dongle attached to our TV were suddenly all unable to find my network.The WLAN light on the router was still lit up. I connected my Acer Aspire 5742Z laptop to the router via an ethernet cable and it worked fine. I connected to the router and it said there were no errors.
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'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.
I just did a clean format on my acer aspire 5100 laptop, everything went flawlessly until the last driver - the network driver. I installed the Atheros WLAN wifi driver and it installed fine. However, it showed a bubble in the task bar saying "Wireless networks detected, click here to connect" so i clicked the bubble and the network connection tab popped up, but it says "No wireless networks were found in range". I don't know what to do, it is recognizing there are networks in range, and then telling me there aren't and none pop up in the list.
The network adapter is: Atheros AR5005G and it is working properly
Edit: I can connect using ethernet, it's just not showing any routers in the network list to connect to
My laptop is reading a full WiFi signal from my router. I am currently connected to the router via Ethernet on the same laptop. I've been reading tons of old threads to troubleshoot this. I'm at a loss. I have used this current networking hardware for more than a year without any problems. I do have a pretty old router but my iPod connects to the WiFi no problem at the moment. Here's what I've tried so far:
- soft reset of router - power cycle modem and router - removed saved network information from the laptop
I've got a Dell laptop with Windows 7 and I'm unable to connect to public wifi. I have a home wireless connection that I'm able to connect to, and I'm able to connect at friends houses. But when I try to connect at a local coffee shop, it doesn't work.
I have just moved homes and I am unable to connect wirelessly to the internet through the network in my new house. The computer is connected to the network with excellent signal strength but access shows as local only and will not connect to the internet.
All other computers have been able to connect to the internet with no problems, and my computer will connect to other wifi connections, no problem.I can connect with a wire directly to the router, but no luck with wifi. I have also had this problem with one previous wifi network. I have tried many things, including taking the compter to a computer shop for them to look at and having another professional look at it, but so far no luck.

i bought a second hand acer one net book for my daughters birthday in a couple of weeks when i first tried it it work i could go on the net, now it wont says can't find server. connection strength is strong 100% system is running ubuntu.
I just got a Acer veriton m670g and it fails to find any wireless networks.This is the first time I'm booting up the computer, so I haven't downloaded anything fishyPS: I dunno if this really but when I open the devmgmt.msc window and look at "Network Card", I have this listed:- Intel(R) 82567LM-3Gigabit Network Connectio
a while ago my pc had an eroor, ive fixed it and replaced windows vista and now im on windows 7, i have a connection through an ethernet cable plugged into my router but my laptop cannot find my wireless network but it works on my DSIXL, PSP and Xbox 360 so its not an internet problem. my pc model is an Acer Aspire 7730.
I just recently installed windows vista on my toshiba laptop model L3O5D. Every thing went smoothly and before you know it I was up and running, with one major problem, I can't find any networks to connect to to access the Internet.
Suddenly, for some reason, my two Lenovo laptops last week (one is Windows XP and one is Windows 7) couldn't find any wireless networks. When I click on "View Wireless Networks" all that comes up is the Iban computer to computer network.I know the wireless network router is working as I can connect to it with my non 3G iPad. I also took both computers to work and couldn't connect to an open wireless router there.
We just got our router fixed and everything was working fine till after. Everyone elses computers and my iPod connect just fine. I have done a system restore already and that did nothing. I have no experience with computers. I cannot call tech support cause I am in a foreign country and don't know the language. What else can I try doing to make this work?
How do i find my networks password that I have lost. When I try to sign in on my Iphone it ask for a password that I don't remember. I am using a apple wireless computer. I had this password put on there so no one could break into my system but now I can't get in with my i phone or if i have visters they can't use their computer because I don't remember password.
