9/10/2023 0 Comments Rssi 64![]() ![]() We also had lower MCS values due to this lower SNR value. Yes, we noticed this when we first started trading out 180's and 200's for 300-16's and 300-25's. At these levels it's not a problem as all the 300-16's are maintaining MCS 9 up/down but, is this expected behavior of N vs AC ? The 180's were around -55 and 43dB SNR while the 300-16s are -55 and 33dB SNR and all we did was slide the 180 off its bracket and slide the 300-16 on (sweet! Sure wish this worked with F200 to 300-25 swaps.). Installed a new 3000AP, replaced 3 F180s with F300-16's. We haven't changed out a lot of F200's with F300-25's just yet but the F300-25's constantly have lower SNR at the same RSSI than the F200's when connected to N or AC access points. This isn't an issue when replacing F200's at -65 RSSI and 31dB SNR to a F300-25 at -65 RSSI and 28dB SNR or so but I'm finding that where a F200 would run just fine at -76 and 22dB SNR the F300-25 at -76 RSSI is only getting around 16dB SNR and the customer starts complaining about buffering and slow speed tests. ![]() When we swap out a F200 with a F300-25 we normally get pretty much the same RSSI +/- a dB but the F300-25 has less SNR. I'm wondering if this is a firmware thing or a just how AC is thing. ![]()
