Acer :: Aspire 5920G Wireless Suddenly Lose Connectivity
Jul 9, 2009
I have an Acer Aspire 5920G, with the Intel 3945AGB wireless card. I've had issues with the wireless for some time, where it would suddenly lose connectivity and I would have to reboot for it to find any wireless networks. Yesterday, however, it lost connectivity again, and now is unable to connect even after several reboots.
The wifi switch is on and lights up. Acer eNet manager tells me there are no wireless networks, whereas Windows Vista's network manager tells me that I'm either a) Connected to my wireless network but with a limited connection or b) Not connected at all, but wireless networks (including my own) are available. It always fails to connect. My wireless router is a Dlink DIR-615.
I've tried inputting the WEP key again, no results. I've tried rolling back the wireless device driver (to 11.1.0.86), no results.
My husband has an identical laptop, with an identical setup, and everything works just fine for his laptop.
I did nothing out of the ordinary last night when this happened - no settings were changed, etc. The only thing I did do that I don't do every day, was that I ran the disk cleanup manager, and it cleaned out a few temp files, but I thought that this was a harmless operation...

I have an HP 10 S Notebook and I will lose wireless internet connectivity after I've been online for a while. It will show as "limited" and when I click to reconnect it shows I have no internet available. I've run the diagnostics when that has happened and it tells me there is an issue with the wireless card. I can shut the computer down and restart then it's working fine. This has been happening about once a day.Â

Doing a reset didn't solve my problems of connecting to Public Networks.  It is definitely a problem with the Windows 8.1 Broadcom Wifi card.

Lenovo Ideapad z585
AMD A10-4600M APU w/ Radeon HD Graphics @ 2.30 GHz
6 Gb DDR3 RAM
Windows 8 64-bit
Broadcom 802.11n Network Adapter
Â
My network card is on the fritz, to put it simply. I randomly lose internet access, and my network connection is listed as "Limited Access". Sometimes turning off the adapter and turning it back on solves the problem, but sometimes I need to do a full reboot. My system is the only one affected, so I know its not the router. I have already viewed the similar threads and tried the methods advised with no success.
So far I have:
-Updated my drivers
-Disabled Broadcom Bluetooth service at startup
-Disabled Hybrid Sleep
-Told Windows not to shut the network card off.
Â
I did a System Refresh last week and that's when the problem started.

Acer Aspire E 15, Windows 8.1
Â
Background (in as much detail as possible):
Â
Earlier this week I wanted to use Pokerstars, but I was due an update (I already had it installed). I updated and loaded it up, although it seemed to lag at the log in screen, so I CTR+ALT+DEL and ended it in task manager. I reopened the program and had the same issue, so I task manager'd it again and it still didn't work. So I rebooted. When I rebooted, all of a sudden I had no option of connecting to a wireless network - only ethernet and VPN in the settings.
Â
I have been into device manager and can see that I have a Qualcomm Atheros Driver in my network devices, although it has an amber warning with code 52 (driver unsigned).
I tried going onto Acer website and downloading the latest driver, which comes with a set up package - unfortunately this didn't work. I tried uninstalling the driver and pointing to the driver that I had downloaded manually; but every time it tells me 'You have the best driver set up for this device' and reverts back to the unsigned driver.
Â
I have tried FN + F3 to disable and enable flight mode - no impact.
Â
I read somewhere about updating bios settings - but there are none in the download section when I put my serial number into the Acer website.
Â
I also tried downloading drivers from other external website and downloaded some third party program called 'Driver Assist' as the way the page was set up fooled me into thinking that was the legit download - it didn't work, and I have subsequently uninstalled it
Â
I have only had the laptop just over a month new, and all had been working until then. Extremely unlikely to be any other spyware as the only things I have installed on here are Steam (FM15) and Pokerstars. I don't even really use this for browsing, just those two apps.
Further info - not sure if relevant but I installed the Acer WLAN + Bluetooth setup as a potential fix, and the bluetooth element seems to be functioning fine - not sure if they're on the same integrated card?

I have 5920G for about only 6 months.
My HDD temp is usually between 45-50 C, but just a while ago, it suddenly rising to 55-58 C!
As far as I know, 55 C is too high for HDD, that's why I'm so worried.
I already check the task manager, and nothing unusual. I wonder what make the HDD temp getting high.
I want to check the HDD fan, but I don't know how to do that...

Just bought an Acer Aspire E15 and have been setting it up today and managed to get connected to the internet through the wi-fi however I have noticed that the wifi keeps dropping and leaves me with nothing and then I have to manually go in and select the router again. This is happening all the time, I am on the internet for no longer than 2 mins before I get the unable to access the network. There is no problem with the network it just seems to be my new laptop. I looked this up and was told to change the power management settings and did so and am still have the same problem. I also updated the driver and again am still having the problem. Also tried ipconfig /flushdns and again the problem persists!

Windows Vista Ultimate SP2 (64-Bit) (problem is also there with Windows 7)
I sometimes try to connect to a network, then the wireless led suddenly orange although Wireless is Enabled. My friend who has an XP system can connect to that network in the cafe just fine so does everybody else, but on my system, it says connecting, then the icon turns orange as if there was no wirelesss card installed.
I am using the Intel WiFi Link 5100 AGN v12.2.0.11 Driver which was installed through Windows Update along with HP Wireless Assistant v3.50.2.1
Now I have an orange icon for wireless, although wireless is enabled in both device manager and through the touch key.
the icon will turn blue if I restart and wireless access will be restored, but I will lose it again if I try to connect to a wireless network.

I have an HDX 16-1140us laptop. with the intel WIFI 5100AGN card. I could get speeds to the max in my house which is about 260 KB/s. Now my sister got a DV6-1334ca this christmas, and ever since then my speeds have gone down to 20KB/s while she gets the rest of the given bandwidth. Any ideas why or how to adjust it so i can get half the speed? we both have the same wireless card, and the router is a Linksys WRT54GC. any type of tweak i can do on this router or a program? i have a WIFI 5100AGN card and she has a 1000AGN card

I've home network with bunch of PCs on it. I've Verizon FIOS and they have provided wireless router. I've installed retail copy of OSX 10.5.6 on one of my system. Everything is working fine including wireless. It can see my existing wireless network. But when I try to connect it only allows me connecting using WEP. After I put in my security key it fails to connect. It does connect to open network in neighbourhood. Is there a way to make this work ? I've 3 other PC and all of them work fine on network. I tried restarting router but it is not making any difference.
I tried connecting using ethernet and it worked fine. I got latest updates from Apple and that worked okay too.

So, I've just installed Windows 8.1, and all drivers needed, but I can't see any wireless networks (it says Off under Wi-Fi tab, and there's no way turning it on). Tried enabling/disabling device, reinstalling drivers, and F7 key but it only turns airplane mode on/off.

We have several Latitude E7240's on our network. They are configured with Windows 7 x64. We have been having trouble with this particular model in regards to wireless connections.
When the laptop is powered on and the user logs in, the laptop connects to the wireless network, however it is not getting an IP address from the router. It sticks at "limited connectivity", and gives itself a "169" IP. It stays that way for about 5 or so minutes then finally connects.
The WLAN drivers are already to the latest version, and to "bandaid" the issue, I have to uninstall the Wireless NIC drivers then reinstall them.
At first I was thinking it may be a router issue (Which is a Sonicwall TZ210W), but it can't be because its wireless devices of differing models have no problem connecting and getting an IP address. Also, it starts working once the drivers are reinstalled (though I'm not confident this is a permanent fix).
All the E7240's have the Dell 1506 Wireless card, and are all and originally were) on driver version 10.0.0.268, A02. Also, I have tried turned off any power management settings of the WNIC prior to the driver reinstall.

I had left the Acer plugged into the power socket in the wall. There was a power problem in our building and the electricity went and came back about 4-5 times over a span of 30 mins. This has happened before so I paid no attention to it. However, after the electricity supply stabilized, I casually looked to see that the charging lights on the Acer was not on. I unplugged the machine from the wall and tried to start it up - nothing happened. I took out the battery waited for a few minutes, put it back in and tried to start it up - again, nothing happened. I took out the battery and plugged the machine into the power socket in the wall and tried to start it up - again, nothing happened. As it stands, the Acer is dead.
The specs are T6660 (I am not quite sure about this but its something close), 2GB RAM, 250 GB HDD, Vista Home, integrated graphics (X3100).
One other point. You know the power brick from Acer has a green light on it which comes on when you have it plugged into the power socket on the wall. When I attached the power chord to the machine, the green light becomes dim and flickers. However, when I disconnect it from the machine, but keep it plugged into the power source on the wall, the light is on as it should be.

I have an Acer Aspire 5315 laptop, which is just over a year old. A few weeks ago, it powered off suddenly. I tried to power it back on, but it wouldn't. I tried booting it with/without the battery and AC adapter, but no luck. The power light does not come on, and fans do not turn on. However, the battery charging light was unaffected, and still turned from amber to green when the battery finished charging.
Then, a few days later, I pulled the battery out and left it out of the laptop overnight, and when i put it back in in the morning, the laptop powered on again.
But - after a couple hours of running fine again, the laptop shut off suddenly again, and wouldn't turn back on. I got it running again after 10 minutes of fiddling around.
Since it was on again, I shut it down using windows and it turned off normally, and powered back on first try. I tried this several times and it always powered back on first try when it was properly shut down using windows. At this point, I assumed everything was good to go, but the laptop shut down again suddenly and I haven't been able to get it turned on again for 2 days now.
Even when the laptop won't start, the battery still charges using the AC adapter; I can tell from the LED on the front of the laptop.

I bought this laptop about a month ago from PC World. I hadn't had any problems with it and thought that I had made a great choice. Now, all of a sudden the fan makes a loud and very annoying noise (similar to that of a drill) for about 2 minutes and the stops. This happens when I turn it on and off too. Nothing I do seems to make any difference and it is happening more regularly now than three hours ago when it started.

My aspire s3 screen suddenly goes black. When I connect it to HDMI I can see the display on the HDMI device. When I disconnect HDMI the screen display comes back but again goes black after some time. It is a hardware problem or some settings to be done. This display problem happens when I restart or power on the note book.

I recently bought an acer v3 371 and was looking forward to using the webcam. Â For the first few days it was fine quality but then suddenly, possibly after an update of some sort, the quality went down and now it looks really terrible. Â I tried many things such as refreshing the computer back to default settings, installing various camera programs (I was using the standard camera that came with windows 8.1) such as Acer Crystal Eye but changing the resolution in these makes no difference at all to the terrible quality. Â
I look in device manager and it just seems to be a generic device 'HD Webcam' and the driver is from 2006, this seems to be the default one that windows selects but there must be a better one, I can't find it anywhere though. I've tried uninstalling and reinstalling the device several times but again no effect. Â I don't know exactly what the webcam is, because if you go to Acer's actual website to look for driver updates they list all of them EXCEPT the webcam drivers.

I recently bought an Aspire 5920G with geforce8600M GT 512MB and windows vista premium.
My graphics card takes more than 700 MB from the RAM memory.
I would like to know if there's a way to make it take less or even disable this option?

I just acquired an Acer Aspire 5920G with NVidia GeForce 8600M GS.
I opened the back cover to see what it looks like and it looks like the graphics card is replaceable. It’s an MXM-II card in 73 mm x 78 mm dimensions.
I’m planning to replace the graphics card and I have couple questions.
Does the motherboard or the system support Nvidia Geforce 9600M GT 512MB GDDR3 MXM – II or Nvidia Quadro FX3600 512 MB MXM II?
How do you upgrade the CPU? I unbolted all the bolts on the heat sink but the frame is in the way and I can’t slide the heat sink assembly out as simple as I thought it would be. Does the mainboard support X9000 extreme CPU?
Is there a link to a manual where it shows how to break apart the laptop? I might change the screen, etc.
Is it worth putting the 5920G on steroids with X9000 cpu and Nvidia Geforce 9600M GT 512MB GDDR3 or Nvidia Quadro FX3600?

Today I was using my laptop (Acer Aspire 5742G) normally and then suddenly my screen freezes and turns off. The picture at that moment when the screen froze was covered with green horizontal lines and some small green squares and then the screen  switched off while the laptop continued to operate normally.
Â
I tried to restart my laptop, but the screen does not turn on, and looks like laptop is working normally because I can hear the windows login  sound (led indicators for WIFI and read data from the HDD are working). I tried to connect the laptop and TV via an HDMI cable, but the TV does not get any picture.Â

So after packing up my comp at a friends house my comp is kinda dead, it was alive before I left my home and everything was fine then.
When i try to start it the cpu is flickering for a bit then freezes so i dont se any bios or anything.
The blue tooth and the lights to the right of the key board are lit to and I have no idea what to do.
Ive tried my old ram mem sticks, pulling out the battery and trying without it, trying a new hard drive, checking for loose cables inside the comp, checking for dust and screaming at it but nothing works.
I talked to some friends and they suggested something called flashing the bios but I have no idea how to do it and I dont know if it will work since i cant se the bios start up screen before it freezes.
I have called acer but they basicly told me to send it in but i dont know if i have any varenty left on it so I rather try to get it working on my own before sending it in if I still got varenty on it.

I believe that my Acer Aspire 5920G was getting too hot, so I checked the temps:
CPU: 81C
GPU: 73C
HDD: 55C
I'm afraid those temperatures are too high. I don't understand why this happens! I don't play games that much now, I have cleaned the laptop's fans recently and I have the air-conditioner on all the day to keep the room with the laptop cool.
What can I do to decrease temps? I don't want to spend money, because I'm having problems with that laptop and my 8600M GS might die soon...

I don't think the issue is physical as under Audio Properties => recording I get response from the 'VU' meter there. However, I am simply not being heard across skype or BF2/OFP VOIP. It's not the levels, which are set to maximum, I've installed the latest realtek HD drivers, and skype is set to 'windows default device'
Windows sound recorder works, although not very well.

i installed windows 7 on my 5920g, however, i don't know what to do with empowering technology. Although launch manager is suggested by acer to be installed the other applications are not listed as compatible with windows 7..
I did download them though, and installed them, but at enet communication manager i got a message about known compatibility issues...So i wonder, if there is a compatible version, or if i can use a version of another laptop that originally came with win7 and if so ,which one..?
