Make all devices connected to the router successfully then the desktop and 2 other laptops can see each other. Leave the router powered up, no other setting required. Second function required the WDS function. http://www.tp-link.com/en/article/?faqid=227 Hope this instruction can help you!

For some strange reason, TP-LINK firmware seems to need an internet connection on the WAN port. Hope the above works for you. If not, we'll try more advanced things.

yes it worked out... thanx a lot
Another thing I would like to ask whether the router truly gives 150mbps connection speed?
Bcause I had downloaded a file in 5mbps speed in desktop from a website.
I downloaded the same file from my mobile (wifi of the same connection ) at 250kbps at the same website.
(the mobile is 802.11n compatible and the wifi signal strength was full in my mobile).

Is there any procedure to increase or control the wireless connection speed?
If yes then how?
And what is the maximum range of gettin a good signal of this router?
