All D-Link devices necessary??

Does this device work well with SBC's 2Wire router or do you need all D-Link devices?

This card will work with the SBC Router (I'm assuming you are using the 3800HGV-B from 2-wire). It supports 802.11G, and the card you are referring to is backwards compatible with that version. The reason for the 802.11 standards is that you don't have to conform to one specific manufacturer.

Will it still function at 300Mbs in the LAN between computers?

No. While different devices that utilize the same standards can communicate with each other, there are manufacturers (Like D-Link) that add extra functionality to their drivers in order to increase the throughput of their devices. In addition to that, you are comparing a Wireless-N device to an 802.11G device. The maximum native data throughput for 802.11G is 54Mbs.

However... if you have another one of these cards in another computer on your network, you could make a peer-to-peer connection between those computers and get up to 300Mbs... just not through the router. BUT... that's not really a problem because the other side of the router is what... 6Mbs? Remember you are only as fast as your slowest link. So if you are talking about going wireless to the router and then out to the Internet, you will only get the speed of the link to the Internet.

Even if you were going through the router to another device connected to the LAN side of the router, you still won't get 300Mbs because the switch on that router is only 100Mbs. The only way you are going to get 300Mbs is to have another device on the network that also is Wireless-N.

So if two cards on two desktops have the fast card and the SBC router is allocating DHCP to them both, will the two function at the high speed.  Thats not considered peer to peer, is it?

No, not really. See the cards have to establish a connection with something. If you are connecting to the wireless access point, then they are establishing the connection to that. If you want them to talk to each other, then you'll have to establish a direct connection between the two machines. Unfortunately, most wireless cards will only allow you to maintain an established connection to one partner at a time, so you can talk to the other machine OR the access point, but probably not both at the same time.

If you want my honest opinion, if I have two machines that I need to network and they must have a very high bandwidth connection, I would go for a wired connection. Of course that must depend on the ability to run a wire between them.
