Will This Help PS3

Will this help my PS3 get a better wireless signal, I had every thing set up correctly but kept getting the DNS error. My signal percent is usually only at 62%, which seem to be not high enough to get online. Will this help increase the signal to 100%, if I plug it into the PS3 USB port.

Also, I am aware that the PS3 already has wifi, I'm simple asking if this wifi router will boost the signal, going to the other router.

No, plugging in that device will either do nothing or cause a conflict on the PS3's hardware. It's not something where that WiFi adapter can amplify the PS3's onboard wireless signal...things don't work that way.

Your better option is to probably get your PS3 closer to the source for WiFi in your house, or to just hard-wire the thing with an ethernet cord. Ethernet may not be as nice as WiFi, but it's almost always faster by a big margin.
