My Humax said 65 and achieved less than a tenth of that in practice!
I'd start with adaptors for router and Humax only. However, before spending any more money I'd be inclined to plug TV and Humax in close to the router and see if that works, and if that doesn't try connecting with ethernet cable. And there are other options for strengthening wi-fi which you can google for.
