Speed over T-Mobile on GLX-3000

I have configured my router for TTL=65 and when I ping from my PC, it does show TTL=65.

However, if I do a speedtest from my phone with my SIM card I get a speed of around 156mb down and 6 mb up. If I put that same sim card in my GLX-3000 and do the same speedtest I get 54mb down and .40mb up on my phone; and I get 26mb down and around 1.0mb up on my PC. This is the SIM card from my regular cell plan, US based.

Hints on what I should look at next?

hello
Are both phones and x3000 4G?
What your apn selected?
Can you see which band your phone is using?
