Hello, I have a problem with my TP-Link TL-WDR4300 running OpenWrt 18.06.2. I am 100% sure that in the past I could get ~1000 Mib/s speeds through ethernet with this router (but with an older version of openwrt). I tried to run iperf (-s in the router, -c in my pc) but now I can only get ~260 Mib/s speeds. I also tried different cables and new ones, to no avail.
Is there any known problem with gigabit in recent versions of openwrt?
