I have an Aspire 4520 Vista with Home premium and AMD Athlon 64x2 cpu.
A few months back one day I just lost my wifi capabilities. Recently I reinstalled windows and wireless worked just fine. Yesterday my wifi stopped working again. When I push the wifi button on the keyboard it says "no device"
I looked in device manager the wifi card does not show up
I reinstalled the drivers. No success.
Can anybody help me? I don't want to reinstall vista again and after 2 weeks I loose my wifi again.
Possibly the PCI bus error message is telling you that the wireless adapter has failed -- but worth checking that it hasn't just slipped out in the mini-PCI connector.
Look for a removable panel on the laptop underside -- be careful because mini-pci adapters resembles memory module. Try not to touch either without first momentarily earthing yourself on a radiator or tap.
Just ran the latest chipset update off the Acer website and the wireless amber light came back! Didn't even get around to updating the WIFI drivers yet and its working fine.
Can you tell me very specifically step by step how to do this? - I am having the same problem - I cannot get the wireless amber light to come on so that I can use my WIFI. I emailed Acer and they responded back to me they would charge me $199 to schedule a repair! outrageous!
dear can you please tell the steps to update the chipset update
Am sure you would have gotten rid of your wireless lan problem on aspire 4520, still let me post something that may be useful for others if not for you.
I have the same problem of wireless just gone off and not enabling. Installed drivers n no. of times.
So as was suggested above: I updated drivers from acer website manually: http://www.acer.co.in/ac/en/IN/content/drivers
On this page, i selected Notebook > aspire > 4520 and then under my selection there is a dropdown asking for which version of windows I am looking the drivers for. Select Windows XP so it will just show you a complete list of drivers which can be downloaded and installed.
I have just downloaded Wireless LAN_Broadcom_188.8.131.52_XPx86.zip file from there, installed it and now its asking me to restart so after restart I will check and post another comment here to inform you guys if this driver in above zip file works or not.
nope. no luck. nothing working on to enable this wireless lan. Guess I will need to buy a usb wireless adapter to be able to continue using this aspire 4520 notebook from acer.
Next laptop needs to be bought but I dont yet have money for it. will need to wait
