Greetings to the whole community. I am from Venezuela and I am helped by the online translator. I hope I can make myself understood.
My problem is the following: I have a grooveA AC 52 as AP and a RB750Gr3 as administrator, with the intention of creating a small network for mobile devices.
the groveeA AC 52 comes with a 6dbi antenna that gave me about 150mts for mobile equipment. I decided to buy a 12Dbi antenna to at least improve performance in those 150mts.
buy the TL-ANT2412D antenna and the performance is lower than the original 12dbi antenna. measuring the signal, it is almost the same as with the 6dbi antenna but it has worse performance. Lower CCQ, higher ping, with more losses.
I have tried various configurations. gain of 0 and 12, even the little recommended TX POWER at all rates fixed at 27dbm. I understand that mobile phones have limitations in bidirectional communication at more than 100ms. but I would at least expect the 12dbi (1.2m) antenna to perform better than the 6dbi (0.25m).
Any ideas that can help understand my problem would be greatly appreciated. Thanks in advance.
