Recently bought TX50E and installed to my desktop. 

Current was subscribing a 300Mbps download and 50Mbps Upload package.

But I'm only getting max 110Mbps download on my desktop with 5Ghz connection and 2.4Ghz was able to reach around 100Mbps download.

The Wifi router model is AC1200 dual band (ISP version).

While trying the 5Ghz connection on my mobile was able to get 250-280Mbps download. 

Do anyone know what was the configuration miss out that cause my 5Ghz speed was stuck at 110Mbps?? 

Thanks in advance.
