I am Terrance from TP-LINK HQ Office.
For the WAN-LAN rate of TL-WR1043, it goes approximately 120Mbps-130Mbps due to the limited chipset capability and it is hard to improve by upgrading software. TL-WR2543ND is the same, both seems to have a limited rate for the high bandwidth environments. However, the LAN-WLAN rate shows normal.
For the high WAN-LAN rate products, our new products TL-WR1042ND ( have a 300Mbps+ WAN-LAN rate) and TL-WDR4300 (goes up to 900Mbps by enabling HWNAT), they will be released on April and May approximately.
Best Regards
