I expanded my home network and installed a range extender downstairs. The modem router is located upstairs..I I need someone who has a good knowledge of setting up a range extender and resolving connectivity issues with a Sony PS5 located downstairs right next to the extender. My modem upstairs is a TP Link AX6000 and the range extender downstairs is a TP Link is an AXE5400 and the NBN speed upstairs is 200mbs. My daughter cannot use her PS5 due to slow to no speed at all.

We have lost the network Connection to our CCTV and unsure how to fix it. We can still see main CCTV on site but have no remote access any longer. Need to fix ASAP

My computer internet signal is extremely slow (1 bar). I work from home, I need it to be faster and to stop dropping out. My router is upstairs, I'm using mesh downstairs. Could it be my household network, do I need a faster more powerful router, is it my laptop settings, is my laptop faulty? I need help to sort this out ASAP. - Due date: Before Saturday, 7 October 2023

We have a functioning CCTV already setup in our sushi shop. We need assistance setting up a network connection for the internet and installing the hard drive for the DVR as we have used all of our network ports so far, maybe as simple as installing an adaptor? into an existing port? We also require another network connection for our back of house monitor to be plugged into so it can run. We also require some electrical work for someone who can install spotlights above our main shop signage to maximise evening lighting on signage. - Due date: Flexible
