Are both devices that are in the same room also in the same room as the VM hub?
It could just be a poor design of the laptop wi-fi unit, or location of antennas in it. Do a BB speed test quite close to the VM hub.
If the laptop is in the same room as the hub, it is always best to connect via Ethernet cable (Tudor could write a book on wi-fi problems 🐵
If the laptop is not in the same room, think if Ethernet cables could be run, if not now, then when re-decorating or fitting new carpets (run cable under floorboards, not directly under carpet).
The trend now is for mesh systems to improve wi-fi coverage. The first unit connects to the VM hub with a supplied ethernet cable (which you then put in router mode) and the other units (you can buy a starter 3 pack and add more units if you wish) you dot around the house, such as they can either 'see' the main unit or another unit over wi-fi & they all talk together and relay your wi-fi signal back to the VM hub. They can also be linked together (or linked by a switch) via Ethernet cable for even better performance.
The downside is that you cannot use the four ethernet connections on the hub, so if you are using these, a switch will be required, Tp-Link 4 port for £13 or 8 port for £19
Look on Amazon for the Tp-Link Deco S4 3 unit set. Price fluctuates between £99 and £100. There are cheaper & more expensive units.
