Archer c6 bad WiFi
I bought this router not long ago and it was working fine the first few days but suddenly WiFi has dropped to under 1 Mbps upload and some devices further away can't connect at all.
Edit: After some more testing it seems the WiFi is mostly working fine, it's just odd that some devices further away are no longer connected. The 1 Mbps upload seem to only happen on android devices when testing the internet speed in browsers. (Does anyone know why this happens? It's very misleading.) The Speedtest app actually shows the speed it should have as long as it's not located too far away. I'm gonna run a few more tests but I was mostly just shocked by the weird upload readings.
After another week or so? It seems WiFi drops sometimes which is really annoying. Also the browser internet speeds seem to be able to get higher now... no clue what that's about. I'm probably gonna return this device and get something more stable.
