Keep your router as far away as possible from other electrical devices as well as those which emit wireless signals such as cordless phones, baby monitors etc.
Cadwch eich llwybrydd mor bell â phosibl oddi wrth ddyfeisiau trydanol eraill yn ogystal â'r rheiny sy'n allyrru signalau di-wifr fel ffonau di-wifr, monitorau babanod ac ati.
