I could not enable WEP between my laptop, using the netgear ma401 pcmcia card, and a Linksys base station. The latter is the Linksys Wireless-G ADSL Gateway, the WAG54G. Connection was unreliable, often with a 'data frame error' message appearing.
I found that the 'advanced settings' on the Netgear card were not matching the default 'advanced wireless settings' on the Linksys
Making the settings of the linksys station compatible with the NetGear laptop card seems to have worked - for the moment, anyway. The NetGear settings were changed via Device Manager (some settings had to be in multiples of 128 or 256), and the linksys settings via the admin page, to:
*Authentication algorithm - auto *Fragmentation threshold - now set to 2304 *RTS threshold - now set to 2304 *Preamble - autoAny comments welcome. Hope this helps someone.
