Issues with Chromecast v1 connecting to Virgin Media Super Hub 2ac
Compared to the previous Virgin Media router I had, this one has separate configuration areas for 2.4GHz and 5GHz wireless. A bit of messing around with trying to connect the Chromecast to either 2.4GHz and 5GHz wireless appeared fruitless until I dropped down the Wireless Mode setting from the default of up to 144Mbps to up to 54Mbps.
Thinking back on it, I’m pretty sure that it was what the previous Virgin Media router was set to.
