Review on Enhance Internet Speed with TP-Link AC1200 Wireless Dual Band USB Adapter (Archer T4U V1) by Yusri Awin ᠌

I connected a new Internet to the apartment, GPON 200 mb / s. immediately checked the iphone 7 gives out almost 300 mb / s for download and 250 for upload. But the laptop turned out to not see the 5GHz range and gives out only 35-40 mb / s. I bought an archer t4u specifically for a laptop, plugged it into USB, chose a 5GHz network, connected and the download speed was 4-5 mb / s and 170-190 mb / s by upload. Very strange. I switch to 2.4 GHz, the speed is the same . I turn off the adapter, connect through my native network card and the speed again becomes 35-40 mb / s. In what a problem and did not understand.
