hi, I've searched this and other forums and still with my problem, I'll appreciate help a lot. What do I have - 1. D-LINK WIFI ROUTER + ADSL 2740U (802.11n mode enabled) 2. MBP WITH 10.4.11 and AirPort (802.11n mode enabled) 3. Windows 2003 Server SP2 with shares 4. I'm trying to copy large files (500-1000MB) from server to the mac os and the speed is about 50-100kb/s, so 1.3GB file is transferred over 3 hours. Is it ok? The windows station works faster (XP) but I like mac os x. the protocol is IP only and router is DHCP server change the distance from router to mac is making no difference any any suggestions?
