I’m new to using dual-band WiFi, so apologies if these questions are common...
My old laptop has an inbuilt 802.11n 2.4GHz WiFi adaptor. It will only talk to my Smart Hub2 at 144/72Mbps even when right next to it.
I have now bought an AC1200 USB adapter and this works quite well on the 5GHz band. The laptop will talk at 835Mbps when close to the router, but only about 535Mbps when used in its normal location on another floor. No real problem with that, it’s still a lot better than on the 2.4GHz band.
The 5GHz signal is only about 3/4 strength at the laptop’s normal location and does seem to drop out on occasions. I would like to run both the 2.4GHz and 5GHz connections concurrently, with the idea that whenever the 5GHz signal drops out the laptop will continue working on the 2.4GHz band until it can switch back to the 5GHz band. But will that actually work?
I have connected both bands concurrently, but there seems to be no way of checking which one the laptop is actually using (or does it actually use both ?). Also when both are in use Windows only reports the speed data for the 2.4GHz adapter and not for the 5Ghz adapter as well.
Am I trying to do something which is not feasible, or simply not doing it correctly?
