I have a WRT54GX4 Wireless-G Broadband Router with SRX400. I need a SRX400 capable PCI Adapter for my desktop. However, I only see a Wireless-G Notebook Adapter with SRX400 (WMP54GX). Is it true that the only way to make use of SRX400 is to use the Notebook adapter and Desktop users are SOL? ...or will the Wireless-G PCI Adaptor with plain old SRX take advanted of the router's new SRX400 technology? Any response would be greatly appreciated.
