I am new to Openwrt and noob in networking in general. I have a new TP-Link TL-WR902AC. As the title says, whenever I upload at my max internet speed (not max router speed) my router always timeout, it happens usually like 4 seconds after the upload starts. I know this is my router's problem (not my ISP) because while uploading, I tried pinging my router (192.168.0.1) from my phone and it still timeout. And this doesn't happen with download as far as I know. Latency rise but doesn't timeout.
Since I am a noob, I don't know what settings I should change. I'd be glad if anyone can help me out, thanks.
PS : My internet speed is around 100mbit/sec while my router max speed is around 500mbit/sec? So, I am assuming reaching speed limit shouldn't be the issue, plus the problem doesn't happen with download.
