Troubleshooting the Wireless Network

If you experience trouble using your wireless network please examine the following:

Check if you have wireless connectivity

Check on your wireless equipment if it has wireless connectivity with Internet Gate. Usually, if there is no wireless connectivity, there is a warning or error message displayed by the client. Many clients also feature some kind of a signal strength meter.

If you have bad or no reception at all, try moving your wireless equipment around. Moving the equipment just half a meter can often improve signal quality dramatically. Try also to move the equipment closer to Internet Gate.

The wireless signals are absorbed by walls, floors and windows making indoor reception very uneven, with many “blind spots”.

Compare Internet Gate settings with wireless PC settings

The SSID, WEP, key, Authentication type, etc. settings of your wireless equipment must be exactly the same as your Internet Gate.

Check if you have DHCP connectivity

Check if your wireless PC has received an IP address from Internet Gate by entering “ipconfig” into a command window on it. The IP address should be on the 192.168.30.x subnet. If not, reboot your wireless PC.

Check that your Internet Gate has DHCP server enabled for the AIR interface.

Check if you have IP connectivity

On your wireless PC enter “ping” into a command window to test IP connectivity with Internet Gate.

Wireless Mode

Select wireless mode 802.11G only on the Wireless page.

Wireless mode 802.11B/G may cause degraded performance and stability especially with battery operated devices such as iPhone, iPod, Android mobile phones, etc.

Stop Wireless Zero Configuration

Windows XP has a feature called Wireless Zero Configuration that monitors WLAN changes. Though it might be convenient to use, the feature greatly reduces wireless performance, and could even make the wireless network stop working completely. You are strongly recommended to stop Wireless Zero Configuration

Wireless speed notice

While the 802.11 standard states 50Mbps as transfer speed, it is worth to point out that actual data transfer speed is usually about half of that value. If data is transferred from one wireless unit to another (i.e. not wireless unit to wireless access node, but between two wireless PCs), transfer speed is further drastically reduced.

These are not limitations of your Internet Gate but of the 802.11 standard.
