Been with Optus for a few years, and been reasonably happy with the crappy CG3000 modem/router we were given. Up until recently that is.
Since netflix has come out, the wireless no longer stretches to my room when there are 1-2 people streaming at the same time despite us having download speed of around 70-90mbps.
I'm sitting on a budget of around $150 but can stretch to $200 if it gets me significant improvement.
Appreciate the help!
Buy Asus RT-AC68U or Netgear R7000 Nighthawk wireless router. They're hardware identical with their own software/case.
The Asus looks slightly less hideous than the Netgear and Netgear have had a few major security flaws (as in knew and did nothing about it) in the past year so I would recommend the Asus.
Then put the existing modem/router into bridged mode (google it for the model if you need to but basically it's just disable NAT and disable wireless) and then connect an ethernet cable from any ethernet port on the modem to the "internet" WAN port of the new router and plug your devices like computer into the new router.
