The IronPoint 250 supports an integrated configuration with 10/100 Mbps Ethernet LANs.
One or more access points can be configured as:
• Infrastructure for wireless LANs
• Infrastructure wireless LAN for roaming wireless PCs
The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily encounter
interference from other 2.4 GHz devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless LAN performance, try the following
measures:
• Limit any possible sources of radio interference within the service area
• Increase the distance between neighboring access points
• Decrease the signal strength of neighboring access points
• Increase the channel separation of neighboring access points (e.g., at least 3 channels for
802.11a, or at least 5 channels for 802.11b/g)
