This is the portion of the XO Troubleshooting Guide for diagnosing problems with the network connection of an XO laptop.
Under Construction
Qualifications
Location
Installed Software
Are all network icons (circles) missing from the neighborhood view ?
A known network is missing from the neighborhood view
Laptop always joins simple mesh 1
Clicking on an access point doesn't work
Software Tools
XO Self-test
A Hardware Self-Test is included in the XO laptop. It includes a test of the networking hardware, where it communicates with the networking interface and prints out a list of the access points (SSIDs) seen in a scan of the local networks.
Sugar Tools
Sugar indicates the state of the network in a number of different ways. The user interface of Sugar is changing, in particular with respect to indication of network status, in an upcoming (9/08) release, 8.2
Hovering the pointer over the network icon (circle) in Home Screen provides information about what network the laptop is currently connected to. The absence of a network icon (circle) in the Home Screen may indicate a problem with the networking hardware, but is also frequently associated with software bugs.
The neighborhood view should show a circle for each WiFi (802.11b/g) access point in range, plus three more for the built-in mesh channels. Hover over a circle to see the SSID (name) of the access point or the number of a mesh channel.
Linux Tools
Need links for these tools, accessible using the Terminal activity (or vtty on most laptops):
- lsusb
- iwconfig
- ifconfig
