Yes u can use ur own router no problem. Recently, maxis tplink the black colour got issue on the chipset. Btw, the dongle provided especially for one prime customer only can be use in tplink router. U can bring the router anywhere together with the dongle in order to get internet. That dongle already lock. So that cant use for pc laptop.

If use own router u need to configuration urself, if call tech u need to pay because of 3rd party. Very easy to configure. However, make sure the router must compatible with DSL port if u use voip.
