I have recently purchases the edimax BR-6424n wireless router for my windows XP PC to connect it directly with LAN and a Windows 7 laptop which have inbuilt wifi. My laptop inbuilt wifi adapter can transfer data around 1.5-2.5MBps (35% signal) to my desktop. But it seems to be slow after purchasing a good USB wifi device (with 5dbi antenna) which speeds up to 300MBps (in 802.11n on 40 MHz). After installing the driver of USB adapter I can see in realtek 11n software that the TX and RX are keep on jumping. The actual speed of Tx: 150 Mbps and Rx: 300Mbps, but I can only achieve around 1.5-2.5MBps transfer. The control shows link is 98-100% and signal strength varies around 58-60%. Then why I am getting such a low speed? How can I improve the connection? If you any tips to improve this will be very helpful. Another thing is usb wifi adapter connected to router 802.11n and the laptop wifi adapter connected to router on 802.11g.
