Hello and Welcome to TSF!
First off...I would update your router's firmware to the latest one and can be downloaded from the manufacturer's site.
========================
From your wireless computer pls. run Xirrus Wi-Fi Inspector
Here's a more detail guide => Double click on the xirrus icon on your desktop of if you have one running in a corner, just click on it. Tap the Printscreen key on your keyboard, open up Paint then choose Edit from the Menu and select Paste, then SAVE it.
