Here’s a funny thing.
I was on 350 Mbps and did the Volt benefits free upgrade to 500.
I routinely hit 380 via WiFi to my laptop with the Hub 3 in modem mode and using an Asus RT-AC86U prior to the upgrade.
Shortly after the Volt upgrade to 500 I struggled to reach even 200 via WiFi to the laptop (although 540 to the Asus router). I tried Router mode and then got the red light of doom and received a brand new replacement Hub 3. Reset to modem mode with the same setup and cables and positioning.
I have disabled QoS and split the bands but am still way down on what I got before the upgrade.
I know WiFi isn't guaranteed etc etc but what could account for this drop please? My stats seem fine too and there are no local issues btw.
