If its right next to the router, don't bother with wireless. Get an Ethernet cable and use wired. It's not really beneficial to have a router right next to the system as still use wireless, in fact it might be detrimental due to electronic interference. If you already have it wired, try disconnecting other devices when not in use. The bandwidth might be taken up by other devices. Other than that, I could only really tell you to check with your ISP or your network settings to see if there is something you can do to improve it.
