anyone noticed the noise floor threshold disappeared from the AC products? I have started using SXTAC and Netmetal 5, both not having this advanced option… used this quite a lot in noisy environments mostly for short links where it helped a lot achieving 99% CCQ. When upgraded these high performance links to AC, the CCQ and performance is now actually worse than with R52n cards in x86 machines.
Its possible to set it in the terminal but doesnt seems to have any effect on the card.
Actually after doing some more tests it seems that NV2 protocol is lowering the CCQ and not noise as I thought… if I use 802.11 I can get 99-100% CCQ but when switch to NV2 it drops to 60-90%… Throughput seems to be a bit better with 802.11 but the latency is too high with some load on the link…
I guess I have seen this behavior already when tried to upgrade existing 802.11n link pushing 200Mbps on 40MHz channel (R52n-M cards, x86 HW) from standard wireless package (v6.7) to wireless-fp (v6.18).. I have reverted to the standard wireless package as it is performing better for now.
It seems this has turned to be an off-topic as the problem with CCQ is clearly NV2…
Anyway would be nice to have the manual noise floor threshold again, is this driver or HW related?
