I recently installed OpenWRT 19.07.3 on my TP-Link Archer C60 v1, but ever since I did so, I started running into trouble with packages dropping like crazy – we’re talking in the 70-80% range of packet loss. When the packages do get through, it’s quite speedy though.
I can replicate this problem both on WiFi (both on 2.4 and 5 GHz) and cable. I can even replicate this problem pinging from the router itself.
If I use the same cable and port that goes from the modem into the router and connect it directly into a laptop, there is no packet loss, so I assume the problem is not in the cable or the modem either.
Any help would be greatly appreciated, as this is affecting me quite a bit.
telco’s modem/router was (by default) set to have its IP as 192.168.1.1
OpenWrt router was (by default) set to have its IP as 192.168.1.1
telco’s modem/router issued the OpenWrt router the IP 192.168.1.2
As a result, it seems that when I connected to the OpenWrt router, it thought it’s IP is 192.168.1.1, but when the packet got from the OpenWrt router to the modem/router that box thought it’s IP was 192.168.1.1.
