Consider the following options: http://www.redpinesignals.com/Solutions/Reference_Designs/Smart_Grid_Comm/RS-SE-601.html http://www.sparklan.com/product.php?func=view&prod_id=43 I don't know about the best choices for multiplying a miniPCI slot, one choice is this, paired with PCI->miniPCI adaptors. Only useful if you have space: http://www.globalamericaninc.com/p1800010/1800010_-_Mini-PCI_Type-III_Module_to_PCI_Adapter_Card/product_info.html There are probably many other resources out there too that I haven't listed. The SparkLAN product is notable as it is not very expensive. -Galen _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
