I have been tethering the day i bought my Zmax. I only have it working for Windows using Chrome.
First!! Enter the APN settings and copy down the default Metro settings, Then add a new APN and copy everything from the default settings into it..
but in "APN Type".. make sure you add dun into it so it reads "default,supl,mms,hipri,dun"
(APN may look different on T-Mobile. just be sure to add dun!)
then hit save and use that APN
Go into your Hotspot settings and Configure it to what you'd like. Then, turn on the hotspot through the dropdown ui and it should turn on.
Then download this
User Agent extension .
Enter the settings for the UA changer and add this custom UA string,
"
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9) AppleWebKit/537.71 (KHTML, like Gecko) Version/7.0 Safari/537.71
"
hit save and use it.
tell me your results!
If this works for you guys as well, i might just make us a Tethering guide
