Chief Delphi - D-Link cant be resetted!

I have a huge problem!
I used to communicate with c-RIO wirelessly but now I can't.
I thought it's because of the D-Link
These are the steps that Ive done and concluded that the problem is because of the D-Link
1)I configured the D-Link and c-RIO with a non-classmate notebook
2)Then I re-imaged the c-RIO and saw the green lights on Driver Station.
3)Today, I use the classmate to connect wirelessley but it fails.
5)Then I attach the classmate physically to the c-RIO to re-image it.
6)The c-RIO is re-imaged succesfully.(It was written)
7)When I open the DS the communication light is green(So it shows there's no problem with the imaging tool)
8)After, I detach the classmate and try the wireless connection.
9)It fails(So I thought there must be a problem with D-Link)
10)I take the D-Link and reset it or just think it's resetted.(Maybe I can not reset it because after I press the button of reset the light doesn't stop flashing.)
11)Firstly I change the IP address of classmate like that
(192.168.0.51) As it says in the PDF of How to Configure the Radio
12)Then I type "192.168.0.50" to internet explorer.
13)And I see a page like that
