Set the Linksys router so that WEP settings are mandatory. For my router this was located in: Wireless—>Advanced Wireless Settings—>Authentication Type. I set it to “Shared Key” in order to make the WEP mandatory.

In the Wireless—>Wireless Security section set the appropriate level of WEP security (I chose 128) and create a password. Generate the keys and note the 1st one, which we’ll use to set up the AirPort settings.

Now, back to the OS X settings. Open up an AirPort settings dialog and join the network you’ve created on your router. Choose your network and then enter a ”$” (no quotes) as the first character in the password box. Following the $ sign enter the Hex characters from the 1st key of wireless security settings that were seen in the linksys administration page. (e.g. $D6AE08…)

This was the only way I found to connect to the wifi network.
