Speed issue with HoRNDIS rel8pre2 on 10.11.5

I installed HoRNDIS rel8pre2 on my Mac running OS X 10.11.5 and it worked like a charm with the first phone that I connected. Today I connected a second phone and while I am able to connect to the Internet without any problem, the speed is miserably slow. The 4G connection should be able to deliver around 35 Mbps (and does so when tethered to a Windows PC) but I only get a measly 2 Mbps or so. I dug around a bit in my Network Preferences and see that the previous phone connected as "LS-5013" whereas the one that is giving me issues is connecting as "Spreadtrum".

Any ideas on how I may be able to get the new phone deliver the speeds that it should would be most welcome!
