Signal is not upgrading from 4G to 4G+ with external antenna [Archer MR600]
I'm facing the strange behaviour. When I connect with external antenna, Signal is not upgrading to 4G+ (rarely it'll upgrade, but not always) staying still in 4G. But when I connect the same antenna with Huawei B535 which I got from my neighbour, it's getting 4g+ signal properly.
I guess this is problem with the firmware. I'm using 2x5m lmr200 extension cable.
