Are there guidelines for upgrading the antennas on PCI Cards and/or routers - Can you attach too big of an antenna? For instance, could I put three of these http://cgi.ebay.co.uk/10-dBi-Wirele...K_Computing_Networking_SM?hash=item35a3db43f4 On my Buffalo WLI-PCI-G300N: http://www.buffalo-technology.com/p...wli-pci-g300n-wireless-n-nfiniti-pci-adapter/ Connection wise, it would work (Uses RPA-SMA). Would I have a far stronger and more consistent signal (I am more after boosting up for streaming media within my wireless network - I realize that it doesn't change the Broadband speeds coming into the house) One more point - I have an N router and N PCI Card but getting a signal around 100 mbps (No where near 300 mbps) so I'm thinking there is room for improvement.
