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)
