WiFi speed on Mac 10.9 is very slow compared to PC
I have a late 2009 iMac with OSX 10.9 and a Windows laptop with 8.1. They both connect wirelessly to my router, but my Mac is much closer to it and should have a better connection than my laptop which is much further. My speed is generally very slow (2 mbps at best) but my Mac just seems much slower. I noticed this when i downloaded a game from Steam a few days ago. The downloading speed peak was about 700 kb/s, but i am currently downloading the same game for Mac but the speed is only 324 kb/s. I am wondering why this is. It may be because more users use the Mac than the laptop (which only I use). It might be due to the specs:
Laptop: 6GB RAM AMD A8 4500m 1.9 Ghz
Mac: 4GB RAM Intel i3 3.06 Ghz
Could someone clear this up for me and give me a solution?
iMac, OS X Mavericks (10.9)
