Guess I am going to need a USB 3.1 port to get the maximum speed from this USB WIFI device. For the time being whilst I only have USB 3.0 and soon an up to 250mbit/s fibre service I should be able to get downloads of 24 Megabytes a second from the Internet as I can transfer data from my USB 3.0 ext HDD to my internal HDD over USB at something like 75 Megabytes a second.
Not quite enough for gigabit internet which needs transfer rates of around 99 Megabytes a second but enough for now. Also not sure if my Router would be capable of sustaining 99 Megabytes a second over WIFI as its only a cheap one.
Well I bought a USB 3.0 one to use on 2 Desktops and 2 laptops. The 2 desktops have USB 3.0 but the laptops only USB 2.0. I tried transferring a file from my USB 2.0 ext HDD to the internal drive and the transfer rate was about 20 to 24 Megabytes a second plenty for an up to 250mbit/s service and better than the built in 802.11n.
Yeah as an afterthought I considered PCI-e but the reason for going USB was the ability to share it amongst machines. It should be good enough for my planned 250mbit/s service and I can't see myself ever going gigabit for £ 40 a month more.
The one good thing about this USB adapter is that I can place the antenna wherever I like whereas with a PCIe one the antennas are at the back of the PC which is not always the best place. Also it's a Netgear USB stick connecting to a Netgear Router. I don't think Netgear make PCIe cards.
Just went round to my brother who has the FttH fibre service already. Using a droid box connected over gigabit ethernet with speedtest.net he got 500mbit/s down 500mbit/s up. With his iPhone X over 5G WIFI 380mbit/s down 478mbit/s up in same room as router.
With my iPhone 6 Plus over WIFI got about 250mbit/s down 250mbit/s up. My AC1900 WIFI adapter will most likely be the same as his iPhone X at best. Might just connect up with an ethernet cable after all.
On the 3rd September speeds will return to the normal of 256mbit/s down 50mbit/s up which suits me as my wireless kit isn't capable of much more then that and it saves me running an Ethernet cable to the router.
