Got this Archer VR300 router a few months ago, and I've been having constant issues with it dropping connection on both ethernet and WIFI. Sometimes it cuts out entirely and the routers page says something about PPPoE connection failed and all the IP address and whatever fields switch to 0's and I have to restart the router. Now recently, it just spikes to 2000 ping and makes internet unusable for a few minutes, then returns to normal. This ping spike affects every device and every application/game. Any idea as to whats causing this?
