Acer Aspire 4520 - Wireless Network No Longer Works
May 7, 2011
Acer Aspire 4520 Wireless network no longer works.
The light on keyboard is lit up but when pressed, it says No Device.
Went out a long time ago and I quit using the laptop. Borrowed external adapter which works.
No updates found for driver.
I have a lenovo v570 with 6gb of ram installed running windows 7 sp1 64 bit along with an intel centrino wireless-n 6150 card. After multiple fresh installs of windows 7 I have been unable to get my wireless card to work until I flashed the bios. After I start windows again I am able to use wireless, that is until I reboot. I get an error that the device cannot start (code 10). I thought there was something wrong with the hardware itself yet every single time I perform a bios flash the wireless works just wonderfully and never disconnects. I kept my laptop on for 3 days and wireless worked fine until reboot. I also noticed that it shows 6gb of RAM is available and then after the reboot I only noticed 5.92gb of RAM available. I don't know if this is a clue as to what is going on but I am investigating this matter myself now. I have yet to find any fixes and I am just looking into the matter personally as there is no reason to use an external wireless card if the internal will work properly. I refuse to be defeated by such issues. I am going to attempt to do a bios flash where I know wireless will work and use older drivers and systematically go down the line to see if a reboot makes the wireless fail on any other supported drivers. Currently Lenovo and Intel has numerous drivers and all tested have been failures so it's time to back to something older and even potentially another models drivers entirely. I would also like to point out that my bios does give me an option to enable/disable wifi as well as a switch on the laptop. I checked to see if either one of these are faulty and neither seem to be. I did notice a bug that the bios update supposedly fixed which happened to be where the boot order made a difference on whether the wifi worked or not. It seems that if the cd was in the boot order first it would prevent the wifi from working.
One of my laptops (Acer Aspire 5741) won't connect to the internet, it stopped connecting last night at around 9pm UK time. It shows an ! in a triangle over my Internet Access bars. When I troubleshoot the message is 'Your broadband modem is experiencing connectivity issues'. My Compaq mini netbook is not experiencing any problems though. I have tried resetting the router, removing and readding the home network and checking the security key is correct -I do also have a VPN from my university which has been installed since April without any problems. Both the laptop and notebook use windows 7 and Firefox.
My laptop works fine on my network for 80% of the time but the rest of the time I get yellow triangle and the system says limited access. The annoying bit is that when this happens my smartphone is still connected to my wifi network and works perfectly so I can only assume there is a fault on the laptop. I take out the network adapter plug then plug it in and the laptop usually reconnects but sometimes it can take about half an hour!
My laptop is an acer aspire6935 and the operating system is windowsvista home premium. The wireless router is connected to a desktop via a yellow data cable.
I recently bough an Acer Aspire 5733z notebook set it up yesterday.I am however having major problems with connecting to the internet (I am writing this on my desktop PC downstairs).I have a Netgear DG834G modem/router which worked just fine with my old netbook - a Samsung N130.The problem is that when I click on available connections, my network isn't there, but everyone else's on the street is My PC is connect to the modem/router via Ethernet and when I plug the Ethernet cable into the 5733z it does connect to the internet just fine - it won't however recognize my wireless network.
Just bought, off a friend, an Acer Aspire 7720G.Before I bought it he wiped everything back to factory settings.When I first started it it was ok, I downloaded google chrome, pokerstars and then all the microsoft updates.Since then I have only managed to connect to the internet once. This was when I left the laptop for around 20 mins and when I went back it had connected to my home network.We have 2 other laptops and an iphone that connects to the internet so I know the router is working.I have disabled the wirless adapter and restarted the laptop but still get nothing.As I type this, on another laptop!, the problem one has been on for 30 mins but still nothing.
Can't connect my NEW Acer Aspire One D257 to my ProLink PWH 2004. Strangely enough my Macbook Air is already connected to my wireless network without a hitch.I see my home's wireless signal on the bottom right but when I click it and try to enter my SECURITY KEY it's still unable to connect.I also get this message: Another computer is trying to connect to your wireless network etc..
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 have an Acer Aspire 5570Z that is running Windows Vista with an Atheros AR5007EG Wireless Network Adapter. The Windows installation is a brand new clean install with all drivers on the computer being the latest and greatest from their respective manufacturers. Now for my problem...I am unable to connect to any wireless network using either the onboard wireless network card or an external USB wireless network adapter. When I scan for wireless networks my cpu will see them. I can then select whichever network I want to try and connect to but when I click the connect button it never takes me to the authentication screen to input the WEP key.
I have tried to manually enter the WEP and configure the network but then when I try to connect to the network it still tells me that Windows is unable to connect to the network. It gives me the option to diagnose connection or connect to another network but when I try diagnosing the connection it scans for a split second then it only gives me an option to go view available wireless networks. It is like my computer has lost the ability to authenticate a network connection.
This issue concerns our Acer Aspire1 Netbook. It just suddenly will not let us access our home wireless network. When I followed previous advice by unchecking the IEEE 802.1x box, I received the "40 bit or 104 bit" warning box and upon checking found that the 802.1x box had automatically been rechecked. Needless to say, we still can't access the wireless network.
I bought a brand new acer aspire one 722 notebook and it works fine except I can't connect to the internet. After I run the diagnostics I get the following problem detected: "Wireless network connection doesn't have a valid ip configuration."
Do I need different network settings for when I am connected with my Rogers Rocket Stick vs when I am connected to my home Bell router? When I am at the cottage using the Rocket Stick, I have a good strong connection but, getting to web sites is extremely slow if at all. Win 7 on Acer Aspire One 522, 2 GB RAM
I have a acer aspire 5741 with win7 and i5. i have no problems once i am connected to my network, the problem is the acer will only connect when i do it manually.i have changed the adapter settings to connect automatically numerous times but when i reboot, the settings always change back to connect manually. i have tried other networks but the acer will only connect manually. like i said, once connected it works fine it just will not do it automatically.
earlier this year I bought an Acer AspireOne netbook with Windows 7 startup operating system. It's been working fine until recently when it suddenly does not see our home wifi connection. It shows a list of all our neighbours routers, just not ours. We have various other devices that can see and connect to it just fine (other PCs & laptops, iPhones & smartphones, MacBook Pro etc) A system restore cured the problem the first couple of times, but now that doesn't work. I've tried resetting & restarting the modem & router dozens of times but it does not appear in the list of available networks for the netbook.
My ancient HP desktop connects to the network via wired connection. My laptop connects wirelessly (usually). Both have very strong signals from the router and the desktop connects to the internet just like always, but the laptop isn't getting the internet signal. The laptop is an Acer Aspire 5534 (Costco special) and the router is a Linksys Simultaneous Dual Band N-type. The only real significant thing that was done on the laptop was to install Adobe Shockwave Player with Norton Scan. I already have McAfee on the laptop tho, so I uninstalled the Norton. I'm going to do a system restore in a moment.
I am able to connect the other laptops and gaming consoles that we have at the house. My brother's laptop is an Acer Aspire 5520. Whenever I tried connecting to the router. It would sometimes accept my wpa key at the same time it would give me a valid IP Address. But for some reason it says on the connection status "Unidentified Network" What I did was I enabled guest zone. I was able to connect thru a guest account without using any WPA key.
When I connected to the Internet by using WiFi, my laptop will suddenly disconnected. Sometimes it works to fix it with troubleshooter but sometimes I have to restart my laptop again and again. The troubleshooter mentioned it can be driver/network adapter problem but how to stop DC. I sent my laptop to the service center, they said this is not about my network adapter problem and asked me to reformat my laptop and check whether this issue can be solved or not.
I have an Acer Desktop Aspire AM3100 running Windows 7 Ultimate. I upgraded my memory. When I turned the PC back on I had lost my whole home network and cannot get internet acces back. I have checked my modem by direct connecting it to my laptop. I have checked my linksys box by doing the same. I can see the linksys on my laptop but cannot access the internet. On my desktop I get nothing?The home network and internet access all disappeared when I upgraded memory.
I have been having this problem with limited access with my internet. I have deleted mcafee, norton, photoshop, applications etc. I have restored the system to a previous date. I have disabled firewalls and antiviruses. I have an Acer Aspire with Broadcom 802.11n Network Adapter. I only have wireless as I am sharing my internet and therefore can't test it with an Ethernet cable. I cannot switch on and off the modem box either. I have this limited access which disappears by itself after a few minutes. Then it comes back again. I disable the wireless and enable it again which solves the problem for only a few minutes. I have checked my ip which is 192.168.1.20 with submask of 255 something - which I don't think is the problem.At last, I have switched to Safe mode with Networking but even in this mode I still have limited access. The internet connection keeps cutting off and on all the time.
I have an Acer Aspire X1200 with Windows Vista Home Premium OEMAct.I've tried searching for tutorials on how to fix this issue.I have cable internet through TimeWarnerCable, Roadrunner.Already called up timewarner's customer support and they were unable to fix the problem. Went and exchanged the cable modem for a different one.I've tried changing the network to private, but it keeps reverting back to public itself. (I'm at a different family members on the same street right now after getting this information) [code]
I have recently changed a couple of our companys office routers over from a netgear vpn router to this, all has gone well with the cisco router providing much better speed and reliablilty... But....
I have one little problem, at one of our offices they have a brother printer that has a scanner built in, since this change over the scanner does not seem to want to work,
as far as i can guess the router is blocking communication to the scanner, printing is working fine. is there anything that I need to enable or add to the settings on the cisco to get this working? I believe that the printer is using some kind of multicast to connect to the PC's
When downloading files using chrome I keep getting "unknown network error" before the download is complete. Why is this happening and what can I do about it? I am using vista on an acer aspire 5535 laptop. I tried using internet explorer a few times instead but it has also happened there.
I downloaded both broadcom and athon wireless lan driver and nothing my pc doesnt even show my wireless lan in device manager. but there is a ? in network controler but it will will not conect to internet to download the driver whatever it is.
I have an Acer Aspire 5715 running Vista..the wireless was acting up so I purchased a new Atheros wireless adapter. It runs fine for a while then loses signal then pops back up. I have reformatted the laptop, checked all the appropriate areas (so that it does not turn off to save power) downloaded the latest drivers,and reset my router to factory settings.
I have an Acer Aspire 5315. I recently reformatted the laptop and it now says I have no wireless adapter installed or configured. I'm assuming it's just a driver problem but when I went to find the wireless drivers for it there were a lot. I tried two different drivers for it with no success.
I just bought a used Acer Aspire One 10.1 netbook and I am having some issues. When I got it the pc needed 17 windows updates done. So I did that but I am not sure all the updates worked properly as the machine shut down but never rebooted after finishing updates. After I turned it back on I tried to connect to the internet through my wireless router (which is working fine for other devices), nothing. So I tried a wired connection, nothing again. The wireless is finding my router it is just not hooking up to the internet. I tried ipconfig/all in the cmd prompt and all it shows is that the media is disconnected??? Does anyone have any ideas as to what is going on? The compute seems to be functioning fine except for the internet.
