Wireless Network Performance is too slow

Hello Friend,



We have cisco AIR-AP1231G-A-K9 Wireless Access Point which is attached into Cisco 1861 Router
I did some further testing in the Network. I was downloading a 200mb file from the HP website.  I tried downloading it from one of the PC’s, which is using a wireless connection.
 
It was very slow to download, the timing indicated it was going to take 9 hours.  I then tried downloading the same file using 2nd System one of the windows servers which has a physical connection to the network, and it ran significantly quicker.
 
I also tried running the download from my own laptop and although marginally quicker than the Dell PC it was still slow downloading over wireless.
 
The fact that I was able to download the 200mb file from the server without too much difficulty rules out the problem being with the ADSL modem or the ISP.  It has to be internally possibly on the wireless router in the building.

Can anyone help me to check the wireless settings if something wrong


Regards
