Chrisg34,
Thanks for your suggestion, but it did not fix the issue. Since my original posting, I've upgraded to Windows 10. The issue still remains. I've pruchased a Netgear Powerline adapter to use, which gives me a wired connection. I would still like to be able to solved the wireless issue if possible. I have determined it's an issue on my home network only as when I connect to my work network or my phone's network the speed is consistent with what I would expect given download/upload speed test results.
