I'm not familiar with infrared things, but I know that if you get online with that you will have a sloppy speed if at all. Plus, security might be an issue for you. assuming that you have USB 2.0 capabilities on your laptop, you could try getting the 54mbps wireless 2.0 adapter(http://www.netgear.com/products/details/WG111.php)
If you don't have USB 2.0 capibilities then probably your connection will be slower since USB 1.1 is 40x slower than 2.0.
If you have a free USB port then you are all set.
good luck and next time make sure you give people a really detailed computer spec.
I have a Lan-Plus laptop with an AMD Athlon XP-1600+
1.39 GHz processor & 112 MB of RAM that's about 3 yrs. old. I purchased a wireless router & a wireless
cardbus adapter. However, I didn't realize my laptop doesn't have a cardbus slot. My manual says it has a
Infrared Data Port that allows it to be wireless. What does that mean??? My device manager shows under
network adapters a 1394 Net adapter & a SiS 900-Based
PCI Fast Ethernet Adapter. Under Infrared devices it shows a Winbond Fast Infrared Controller (DMA). I have no idea what those are or what I need to do. All I want to do is surf the internet using my Road Runner! Can I do this? If so, what do I have to do? Any help is greatly appreciated!!
