So i've posted here before, situation is :

-Turbo-ed 500mbps

-Alcatel 240-G-P (white TM box) BTU, link speed shows 1gbps with cat5e cable to PC on LAN1 port.

-Asus AC66U router, latest firmware, NAT acceleration auto (can't force ON), QOS off, LAN cable connected directly to PC with cat5e (1gbps link state) , max speed <110mbps DL .

So i thought it was TM side, gave it a few days but still no progress. Today at a colleagues place, using Alcatel 240G (silver square box) and Tp-link Archer (TM router), achieved 200+ mbps on 5ghz on my phone speedtest. checked WAN cable and its the standard TM cat5e.

My question is, possible for my cat5e (tried 2 cat5e cables, one from asus, one from TM) to be faulty? since it shows 1gbps link speed, or router setup i'm missing? Checked NAT acceleration auto (CTF enabled).
