Hi guys. I bought a wireless usb adapter in japan last week (Elecom WDC-433-SU2M) it's 802.11ac and 5ghz. But when I configure my router's (TP-link ac750 archer c2) region setting and I select my current country, (Philippines) the network would not show for me. But when I tried other countries, (united States, Japan, Singapore) it worked for me. The problem is, whenever I play games while connected to a different country, I get very high and inconsistent ping. I'm currently using a 2.4ghz 802.11n adapter that i bought here and it's working fine. Anyone has a clue on this? Any help would be appreciated. thanks
