For some reason, My router won't go about 500 Mbps; it usually hovers around the 350 range, even though when wired it hits the full 750 Mbps that I'm supposed to be getting. I spent an hour on the phone with my provider, tinkering with channels and whatnot, as I live in an apartment building, and they thought it would be congested on certain channels but to no avail. Then we had a technician from our ISP come to try to fix it, and he also couldn't get it going. He has no idea what the issue is. We went through factory resets on both our router and NBN modem, and still the issue persists. Yet when he plugged in a router that they sell, it worked perfectly fine, which I don't understand since the BE6500 is significantly higher spec'd than the ones they sell. Finally, we thought the router might be faulty, so we returned it and got it replaced and got the exact same results. I'm at a loss as to why this is happening. Has anyone else had similar issues? Any help would be appriciated.
