TRENDnet Wireless gaming apapter

Okay so i had this adapter for over a week now and it is looking great.

Now for some reason i have been getting Limited or no connectivity.

IDK what to do, i resetted the adapter, i used the disc, IT will fine my Wireless network in range.

bit i still get the error then it also does not work on my gaming console's...

IDK if it had to do with me unplugging my router...its plugged back in and usb network card works fine.

But i like this thing it runs faster , do i have to reset something in my router settings??

PLEASE help
