245U-E Wireless Ethernet Modem User Manual
Rev Version 2.24
shows the access point and the station as both being 245U-E modules that will communicate, since both
support 4 Address mode. However, there are some instances where a third party access point may not be
able to communicate using 4 Address mode to a client (Sta).
There are only a couple of ways around this situation. You could change Station #2 to a router, but this may
mean that Station #2 and the Ethernet device will use a different network address scheme, which may be
inconvenient and will require more setup. You could configure the access point to communicate using 4
Address Mode, but this is only possible if the station and the access point support 4 Address Mode (some
third party access points do not support this mode).
240U-E Compatibility
The 245U-E-G modules can communicate with ELPRO 240U-E Ethernet modems, but only in certain modes.
The following table shows compatible configurations. If communicating with ELPRO 240U-E Ethernet
modems, the 240U-Es need to be configured with WDS (4 Address mode), not the default 3 Address mode,
and the 240U-E access points cannot be auto-connect to any WDS access points.

NOTES
1 Connection only if the 245U-E-G is configured with a virtual station (client) which in turn connects to the 240U-E
access point.
2 Connection indication in the Connectivity pages, but it is not a true connection (see “3 Address Mode and 4
Address Mode” above).
3.7 Security Menu
Select the Radio encryption level from the drop down menu on the main index page, and then click Save
Changes. Available encryption levels are None, WEP (64-bit)‚ WEP (128-bit)‚ WPA PSK (TKIP)‚ WPA PSK (AES)
‚ WPA2 PSK (AES)‚ WPA PSK/WPA2 PSK (Legacy), and WPA-Enterprise. The default setting is “None.”
You will now need to go to the Security Menu and enter in the encryption keys (WEP), and passphrase
