Are you suffering from weak signal of internet / cable television? The daily maintenance hereof is born by the tenant.
Common problems include:
Check if your TV is faulty. Use a second device or a device of a neighbour to check whether the defect is in the signal or the device. Always test the incoming cable at the first connection point and not after an extension cord.
Check with your service provider if there is an signal failure in your area. In that case, your neighbours should be having problems as well.
