I have a TP-Link TL-WDR4300. Using latest OpenWRT, my wireless speeds are hitting 100Mbps download with Comcast. LAN speeds are even faster. After I upgrade to lede-17.01.4-ar71xx-generic-tl-wdr4300-v1-squashfs-sysupgrade.bin I cannot get beyond 30Mbps download.
Can anyone with this model TPlink router running on Lede please post your wireless config if you have normal WiFi speeds?
