Thanks mk13139 for this lovely bootstrap'ed OpenWRT build.
I'm still running it on my WR1043ND v2, as the Barrier Breaker Builds  don't contain LuCI, where even post-install wouldn't work.
Unfortunately it seems my LAN is capped to 100mbit/s.
I've found a Forums post two days ago, but I cannot remember the search terms anymore.
Does anyone else have this problem?
Would there be steps to debug this?
Thanks for any consideration,
The trunk builds you referring to don't contain LuCI indeed (as with all snapshot builds), however my build should contain LuCI. Are you sure you've flashed the correct build?
Which LAN speed are you talking about? WAN->LAN or LAN->LAN.
As for the first, this is correct since OpenWRT uses software NAT and TP-Link's firmware hardware NAT (which is obviously faster).
