the 36.00 netgear laptop card in your list there is ONLY 802.11b....i know it says its 802.11g compatible, but its not. that is why its so much cheaper than the other netgear one, which is actually more than you really need b/c it supports ALL standards 802.11 a,b,g (for traveling though...its great!)
the PCI card from Cisco is 802.3, which is weird, but it looks like its backwards compatible. Anyway, not worth it. Cisco markets to businesses, so stick with the comsumer line. Of those, I favor the Netgear, but not the USB one....it won't make the distance u need.
Router = SWEET! It's the newest of the new....but just remember, if you want the superspeed that this router offers (802.11g) then you need ALL your devices to have hardware that supports 802.11g. REMEMBER, unless you're getting a T1 LINE, you will NO WAY experience 108Mbs or even 54Mbs online! The faster speeds are for home network beneifts and businesses. I see the benefit when I transfer LARGE files from my desktop (wired to the router 100Mbs) to my laptop with the 802.11g card.
Cable Modem.....FINE! I wasn't aware you were buying one, I thought you were supplied one from your cable company. But if you are buying one, the netgear is fine. Pretty much all cable modems are the same. Some offer built-in firewalls (NOT RECOMMENDED!), others are wireless capable (i wouldnt go this route either). Just make sure it is compatible with your cable network.
Suggestions....look harder and you might find other options....here is what i found you might like:
Netgear 802.11b/g 108 Mbs PCMCIA card
and
Netgear 802.11 b/g 54Mbs PCMCIA Card (This is the one I have!)
