Hello to Everyone,

I have an AC750 Archer d2 with 2.4 Ghz wireless set on and 5 Ghz wireless set off position.

The router has 3 antenna . I connected the 2 stilo antenna included in packaging in the first and last connector and the TL-ANT2414B outdoor antenna in the central connector.

With this confguration the 2.4 Ghz wireless signal is very low and not stable ( works for 30 minutes with maximum signal and then off .After windows 10 find the wireless network at 2.4 Ghz but the signal is very low).

If I Turn on also the 5 Ghz wireless signal , the 2.4 Ghz network disappear and the 5Ghz network is ok , stable and with maximum signal (but no signal from TL-ANT2414B )

Last one, if I connect the 3 stilo antenna included in the packaging I have that the 2 networks (2.4 & 5 Ghz) works without problem but this is not ok for me because I need to connect the TL-ANT2414B to transmit the 2.4Ghz in another build.

The question is : from the 3 antenna connectors , which I must to connect the TL-ANT2414B to have a stable 2.4 Ghz signal ?
My goal is 5 Ghz and 2.4 Ghz stable in my room with the 2 stilo antenna included in the packaging , and 2.4Ghz stable on TL-ANT2414B to transmit to another build.

Thanks and best regards
