We’re having issues with our internet service in our house at Dulwich Hill, postcode 2203. The NBN and Netcomm router/ modem model number 1951 are located on the floor next to the wall near the door of the 2nd room. We are currently using AGL’s 100mbps plan. The 3rd and 4th rooms are located 15 metres from the NBN and router in the 2nd room. Between the 2nd, 3rd and 4th bedrooms are the lounge and kitchen areas. The internet receptions are very slow and weak, at times no signal at all. AGL has not been able to offer much support except recommending us to upgrade to their 250mbps plan. Can anyone please provide advice, suggestions/help? Would buying a signal booster be helpful for the other 2 back rooms? Thank you, Mark
