Last summer I was downstairs on my pc connected to an ethernet to the router. Internet was great no problems really.. I have a twin brother who is upstairs and he used wireless he lagged alot and he only had problems if I was on my computer and that went on for a while. I have a grandfather who sat infront of me while I was on my pc and I couldnt do it so I moved upstairs but I didnt have a wireless pci adapter for my pc I had a wifi adapter which you plug in the wall to wirelessy connect to the router downstairs and I just put my pc's ethernet into the wireless adapter. I used that for a little bit until I couldnt take the high ping I was getting in game servers forcing me to just move my pc in the corner of my room and I havent been on it since. I have been playing ps4 using a wireless connect to the router downstairs. I have connection problems off and on but not every day. I today just got back on my pc and I am expieriencing constant lag and disconnection from games and discord. My router is the NightHawk AC1700 ,my Adapter is a tplink adapter. What can I do to increase my internet speeds I just dont want so much lag and horrible ping when I play my pc games with my friends.. and a reminder my router is downstairs with the modem.
