Network peak capacity is just a number pulled from pure theory and the blue sky. 150 KbpS or 300 KbpS sounds like there is a lot of other CPU usage in one or both computers. Assuming that there are no network collisions from other services, you could expect about 56% of capacity without traffic shaping. So, for 2.37 MbpS, expect 1.32 MbpS in Simplex communication or half of that (660 KbpS) in full Duplex. The simple answer is never simple and rarely the answer.

So your post rate is best case sceranio with only one computer using the wireless router. Since you are using the router with 2 computers then it effectively cuts your bandwidth down to half, plus you have to figure in packet loss and overhead. If you want the best possible throughput then you should set up a peer-to-peer network. It can be done without a router, without an internet connection, and with short cables. This is how you do it connect the laptop and the desktop together with one single ethernet cable. You will have to manual assign each computer with an ip address, a subnet, and a gateway (go into network places, and look at your network connections. you will see your cards, you can click on properties and look at tcp/ip) So computer one will have a unique ip address, the same subnet, and the same gateway as computer two So it will look something like this computer 1 192.168.1.1 subnet 255.255.255.0 gateway 192.168.1.0 computer 2 192.168.1.2 same subnet/gateway Then make sure you are sharing two folders so you can transfer. at the run command type \computer2 name (you can find that in system properities under computer name)your shared folder then you can transfer fast. (probably about 30-40 mb/min) wireless uses shared bandwidth. So your post rate is best case sceranio with only one computer using the wireless router.

You will have to manual assign each computer with an ip address, a subnet, and a gateway (go into network places, and look at your network connections. you will see your cards, you can click on properties and look at tcp/ip)

So computer one will have a unique ip address, the same subnet, and the same gateway as computer two

So it will look something like this
computer 1
192.168.1.1
subnet 255.255.255.0
gateway 192.168.1.0

computer 2
192.168.1.2
same subnet/gateway

Then make sure you are sharing two folders so you can transfer.
at the run command type \computer2 name (you can find that in system properities under computer name)your shared folder

then you can transfer fast. (probably about 30-40 mb/min)
