According to their website then it's a Compex WLM200NX. Those are specified to draw up to 2.5W during TX. Worst case peak should then be 0.75A, assuming the card have reasonable good high speed decoupling, which is way inside the net5501 design specs. A quick and easy way to check power supply issues is to lower the TX power on the wlan card, have you tried that ? > Please not that i had to use different antennas, as the net5501 has > no space to drill holes for the TNC connectors. Why you sell them > together is beyond me... eeh, we don't sell them, Soekris EU, which are a different company, sells them.
