Drop the distance to the router by half.
I have a netgear a6210 and am currently running on windows 10. I have tried uninstalling and reinstalling the drivers many times, I've even done a few factory resets to try and fix my packet loss and nothing has helped. Whenever I ping my router, every 10 pings or so it drops a packet, it may not seem like a lot but it makes a difference to a gamer... I've tried pinging the router on other PC's and devices on my network and it has no packet loss at all. Sometimes it gets bad enough to where it drops about 20 packets in a row until I disconnect and reconnect to my network on my PC. Could someone please provide me with help on this? Thanks!
