5 GHZ Antenna Will Not Stay Connected
September 3, 2018
This is the US v5.0 of the TP-Link Archer C7 (AC1750). There is only one version of the firmware from April 2018. The DD-WRT site states that v5.0 is not supported and "probably never will be". Regardless, the 5ghz antenna refuses to stay connected and recycles constantly. There is no problem with the 2.4ghz but having a dual band router with only one working set of antennas is completely unacceptable. I have v2.0 of the router running with DD-WRT and the 5ghz antenna works perfectly. I have to assume that TP-Link has deficient firmware for this router. The inability to upgrade to a newer native firmware from TP-Link, or to flash it with DD-WRT makes it unusable for someone like myself who utilizes the 5ghz band. Unfortunately, there's no way to tell what version hardware you're ordering. DD-WRT does support up to v4.0.
