Wireless cannot detect any network despite claims to be working fully

The Acer Aspire One is an inexpensive laptop computer that runs the Windows operating system. The computer does come with a built in Wi-Fi receiver, giving you the ability to connect to a wireless Internet network, when available.
However, if you are having trouble connecting to a wireless network, you must troubleshoot the network connection to determine exactly what is causing the problem with the Internet.
Check the wireless router and high-speed modem.

Borrow other wireless adaptor, then plug it to your desktop. Try to connect ...but U must install the adaptor driver too. If it works, that means your internal adaptor is out of work.

Hi, sorry not a solution, I have exactly the same problem with the same router, even when my laptop is next to the router with excellent signal strength if just drops the connection every few mins, Virgin, who I got the router from claim it is my laptop despite it working perfectly well on other wireless networks.

Try going into your network connections. Disabling the wireless connection and then re-enabling it

try to setup again  wireless card's driver  if it doesnt work your wireless car is break down.

Hello there.

This is a common problem. What i typically do on notebooks that use Intel Wireless, is install the latest drivers and Intel software from their website. 9 times out of 10 this will make it pick up a network that was not previously found, or fix problems with timeouts and so on.

Please click here then choose your version of windows, click 'Go!' and then click "Download" beside the section called "Intel® PROSet/Wireless Network Connection Software for Windows* XP/2000 32-Bit"

When you download and run this file, and install the software, you can then use the Intel utility to connect to the wireless network.

Hope this helps.

my lap top does not show any wireless connection and wont let me do a restore to try to fix it

before you insert the card to the slot run the cd thats comes with it and install the software. after installation of the software insert the card. if it is properly installed, you will see a single computer icon on your task bar click it up and search for a network.

try downloading a new set of drivers and install. http://www.acersupportus.com/2016/07/acer-travelmate-2420-driver-for-xp.html
