Windows 7: slow transfer rate lan and wireless

hi,



I have a desktop and a laptop computer. my desktop had Windows 7 64x for a while and today i installed Windows 7 64x on my laptop. so my desktop is connected via Ethernet to the router while my laptop is connected wireless. so i began transferring big files from the desktop to the laptop and that went at the rate of 1.5mb/s which makes transfers not feasible. so i thought that this was due to wireless and so since my desktop is connected the router via Ethernet cable, i unplugged it from the router and inserted it into the laptop thus creating a direct connection between the 2 computers. well, the first problem that popped up was the unidentified network problem. I spent about 6 hours trying to fix that, reading forums and everything but no fix, but at least i managed to make the 2 computers see and access each others drives. so i began the transfer again and it went at 1.5mb/s again... what to do?

Thank you

Connect both machines to your router and don't use the wireless to transfer as it will be slower. You might want to consider a faster wireless card if you don't have an wireless N card and router.
