The wireless feature (Wireless LAN) on an Acer notebook allows you to connect to available networks. This convenience allows you to use the Internet with network cables, modems or network installation. Acer laptops come with a wireless switch to turn the wireless feature on or off. Once you enable the wireless feature, your Acer notebook can connect to wireless networks within range.

Instructions:
1.Locate the Wireless LAN switch located on the front of your Acer Notebook. Move the switch to the right to turn on Wireless connections.

2.Right-click the network icon located on the system tray next to the clock. You should see a list of available wireless networks.

1. Connect a PC directly to a LAN port on the wireless router with an Ethernet cable.
2. Power on the wireless router/access point.
3. Reboot the PC.
4. Log in to the wireless router though a browser. (Usually 192.168.1.1, with User Name = admin and Password = password, unless you changed them from the defaults).
5. Go to the LAN IP menu and disable the wireless access point's DHCP server by unchecking Use router as DHCP server.
6. Select LAN IP, and change the IP to 192.168.1.99.

You did not say what wireless you are using. The e755 is the PDA and it is having trouble with the connection to the wireless lan. There have been a lot of updates to the wireless devices because of security issues. IT could be that the PDA can not talk to the wireless because the wireless is updated.
