Acer Aspire 4720Z :: After Formatting And Putting Windows 7 Wireless Adapter Cannot Be Found
Oct 19, 2014
I have an Acer Aspire 4720Z. Since long I had been using XP. Recently it was formatted and Windows 7 was installed. But after this upgradation, the WLAN is not working. Have banged my head with drivers and all.
Device manager is showing Microsoft Virtual Wi-Fi miniport adapter (although with XP it simply showed by the name of WLAN adapter as far as I remember). And checking it's properties it says that the device is working properly. When Intel Wi-Fi Technology is tried to get started, it says that 'A supported intel wireless network adapter not found'.

I have an Acer Aspire 4720z notebook and decided to hook it up to my tv. So I got my 7-pin to composite adapter which came with my video card for my desktop and plugged it in to give it a shot to see if it would work and no go, it just won't detect being connected to the tv. I read the manual and searched online to see if this perticular notebook allowed for s-video to composite or if Acer made one for it themselves, again no go. So I was wondering if anyone has this notebook, or the 4710 or 4720 which I think are identical hardware wise, are able to connect one to it and actually get it working?
it uses a mobile intel 965 express graphics chipset.

I put a new hard drive in my Dell Inspiron 6000 and installed Vista. That was horrible so I reinstalled Windows XP. The Wireless was working in Vista. Now when I try to see Dell WLAN it comes up No Adapters.

I'm sure there's an obvious answer to this, but I just did a clean install of my new 1647 and the wireless adapter seems to be misisng
(at least the enable button). I'm on the dell driver site, and I can't for the life of me choose which driver/application will reintegrate it.

I am using ideapad y510p. My wifi worked perfectly yesterday evening. However today at morning I couldnt find any wifi networks. After some research I have discovered that there is not wifi adapter present in Network Adapters and also that there is no wifi adapter in device manager. However bluetooth works fine. I have tried reinstalling drivers (even clean install of everything that may have something with networking). But I still cant see any wifi adapter. LAN connection works just fine. I dont think this should be hardware related problem because as far as I know bluetooth and wifi adapters are both located on Intel Centrino N2230. So I think that if my wifi adapter would be broken than bluetooth wouldnt be working too. I have also tried using system restore point to last week (when everything was working perfectly) but it didnt work.
I have also downloaded latest drivers from intel website and when I run tests with theirs WiFi Software Utility (or whatever it is called) it says that there is no wifi adapter present so it fails even hardware test.

There is a recurring problem where the computer ceases to recognize the existence of the wireless adapter. It doesn't matter if the computer is running 8, or 8.1, nor if the computer is fully Updated. This seems to be a hardware problem or some sort of electrical short, not a driver problem. I have done a bit of research over the last four months or so (when the problem first started happening), and the problem I am experiencing is most likely caused by either a faulty card, or a card that is loose from its socket on the motherboard, and not by a driver/hardware discrepancy.The strange part is the intermittent nature of the computer's recognition of the device. Stranger still is that despite what appears to be a hardware problem, I have usually been able to fix it, either by:
Uninstalling then reinstalling the device's drivers,Restoring the computer to a previous point,Reformatting the computer using the built in Windows 8 feature, and/or Removing certain Windows Updates in reverse chronological order (until the integrated WiFi device is recognized).
Last night, the problem happened again. It was maybe the 4th or 5th time overall, and the 2nd time I was forced to "hard reformat" in an attempt to fix the problem. Until just a few minutes ago, when I partially deconstructed then reconstructed the device, the "hard reformat" method didn't fix the WiFi. After the "hard reformat" didn't work, Upon turning the computer back on, it recognized the wireless adapter, I connected to the network successfully, and here I am now, documenting what happened.
I essentially did nothing significant to the device, and now the wireless adapter is recognized. Why?
All that being said, I believe I have narrowed down the cause of the problem, at least in my case. I believe there is some sort of electrical short issue. The short is caused by one (or perhaps both) of the following:
Assuming the physical location of the wireless adapter is next to the location of the port for the AC adapter, I think the AC adapter, when moved or jiggled by a hand, somehow negatively interferes with the wireless adapter, causing it to fail.Shutting the lid of the computer, perhaps when combined with the above, and/or under other conditions (something having to do with power settings?, something having to do with the state of the network when the lid is shut?), causes the network adapter to fail.Something very similar used to happen on an old Dell notebook I had, as well as on a CR-48, towards the end of their lives. That is, in order for the internet to work, I had to have the AC adapter at certain angle when it was plugged into the computer. Otherwise the wireless connection would drop. It seems like there's a connection there (pun intended), but perhaps not?

My internet frequently disconnects from my Aspire S3-951 notebook with Athros AR5BWB225 wireless adapter. The adapter is loaded with driver version 10.0.0.227. Is there a newer driver that will prevent the frequent disconnects?

I have also tried disconnecting from network and turning off wifi from the signal strength icon as well prior to shutdown. When the adapter stays open when I return to the laptop and connect again it shows that i have been connected via the adapter for days at a time. This eventually leads to the connection being clogged up and causing timeouts preventing me from connecting to the net. I stopped ittwice but dont know what I did.

I have a problem with my laptop, it won't boot up due to "Operating System Not Found", but I've used it already for several times but just yesterday it turned out that "Operating System Not Found". I've tried to check whether the hard drive is a problem and slave it to another laptop but it's still working, it will boot up well in another PC. Now I tried to insert a bootable USB drive just to reformat it for it to work again, but still it won't work. My bootable USB drive is detected and can be found in the boot options but if I select the drive for boot it still says "Operating System Not Found". Then I went searching over the net then I found something that might work like having it boot in Legacy BIOS mode, it boot up then but the problem is my display is distorted and fading, there are lines and overlapping display.

I modify the value of "localy administrated MAC" in the broadcom 802.11g wireless adapter properties.
But when I ask Windows the mac address, it shows me the original MAC of my adapter.
the OS is Vista Home Premium(32 bits) and I have the latest driver.

if it's possible to upgrade my laptop's graphics, because I'm attempting to play a few games on it, and it runs them sooo slow. I don't think the Processor or RAM are an issue, but surely the GFX card is. Another thought I had was maybe upgrading my RAM to 2 GB, which could possibly give it a boost because I think my vid card draws some memory from the system?

i bought a acer laptop @ bestbuy and it came with preinstall vista home. i used the computer fine and all and the internet connects to my router find and was surfing the internet. i then decided to install a fresh copy of my own vista ultimate because i dont like the preinstall stuff that they did because it just clutters up space. after i finish my install of vista ultimate, my laptop doesn't connect to the internet. i know this is simply but i dont see network adapters under the device manager in the computer management screen. i am worried because if i have to install the driver, then i would see some icons with a yellow exclamation mark, but i dont see NETWORK ADAPTERS AT ALL. i dont know how to solve this? any help would be greatly appreciated. thanks all. i've tried to press scan for new hardware changes but still i dont see the network adpaters. i thought if you install vista ultimate, then it will install the wireless drivers for you too.

I Formatted my laptop and installed windows XP (was a successful install) But my problem is....none of my hardware is installed. The WNet doesn't work, Vid Card isn't installed, nor is the Sound Card, and any other hardware that I'm forgetting that also needs to be installed (nothing is installed). I don't have the discs to install them. Can I get the installs for all these online somewhere and burn them to a disc and install on laptop?

I'm an HP user myself, but my girlfriend has an older ACER Aspire 3000 series (about 2.5 years old). I recently reformatted it, and did a clean install using the recovery discs...
Everything seemed to go fine, until I noticed in the disc manager that the Hard Disc has 3 partitions... one is like 3GB, and the other 2 are about 27GB each... One is the Main C: Drive, and the other is called "Acer Data". This is driving me nuts! She only has 27GB of usable storage on her computer, and I can't figure out how to consolidate the 2 Partitions to make 1 large one. Can anyone please help? It's a 60GB harddrive, and I'd hate to see that go to waste for "Acer data" (whatever that is).
Also, the disc was formatted in FAT32... Is there any reason Acer chooses that file system over NTFS? I'd prefer to format the drive with NTFS... I'm just concerned that if I reformat the drive I'll lose all the drivers and stuff. The computer currently doesn't have any programs installed or any data that needs backing up, so I'm not concerned about that stuff.

Is there anyway to boost the Video memory in Bios on the Aspire 4720Z?
My laptop says it has 384 MB available...But It's only using 10 MB. Is there anyway to increase this to the max, so it will take away from my system memory, which is 2 GB?
Here is a SS.
As you can see...The minimum, maximum, and graphics memory actually in use.
