Windows 10: Slow Broadband Speed

My HP Pavilion Desktop PC gives me a download broadband speed of 41.7 mb/s whereas my Thomson NEO 10.5 inch laptop only gives me 3.98 Mb/s. I am on BT Infinity and use a BT Hub5 router. Both machines run the latest version of W10 and are connected wirelessly and these speeds were obtained at the same time and with the machines in virtually the same position relative to the router. Can anyone explain why there is such a large difference and is there anything I can do to speed up the Thomson?

Could be the hardware

You say at the same time that would divide you download between 2 pcs and the first to connect can grab all the bandwidth. What is the wireless type foreach pc ie AC ,n type

The Thomson NEO uses 802.11 b/g/n.

Hope this helps...

What type is the wireless card in each pc?

Thanks for your replies. Although I said that the tests had been done at the same time they were not in parallel there were a few minutes between them. The router is within a metre of the my desktop computer and the test on the Thomson was at a similar distance. I have since done tests on other equipment that I have access to. My Nokia 3 mobile has a download speed of 25.7Mb/s through a brick wall from the router and an e machines E372 laptop gave 41.3 Mb/s, it is about 2 metres from the router in the same room. The broadband feed and router are definitely producing ample speed which you would expect with BT Infinity. The fact that the Nokia which is much smaller than the Thomson can give a good result suggests to me that it is a setting or hardware problem in the Thomson that is the cause but what?
