Re: Help - NStreme2 terrible throughput

The original XR5 cards used MMCX connectors & the new R52H cards use the uFL, but that doesn't seem to be the problem since I'm still getting bad signal quality. I hope to try rotating the top antennas (I'm only using one card on each side now) to horizontal today to see if that makes any difference.
