Hmm did you maybe use the same ssid for both bands? 2.4ghz/5ghz ?
Not that this helps but i got my suspicioun something is not right on the 2.4ghz band theres so many posts about it to bad 802.1n performance to low tx power for some ppl like me on 802.1ax, and maybe this combo adds even more to trouble for 5ghz?
Its just a guess not something i got confirmed on 5ghz, its strange you seem to get the opposite of the issues on 5ghz and not on 2.4ghz.
But if it is then there has to be a concurent issue perhaps?
If you access this channel analysis page does the 5GHz radio detect any other APs and display itself with a strong signal?
I assume you haven’t changed the routers power supply in any way and you’ve already tried resetting the router. But have you tried reflashing the firmware?
There is something I don’t understand: A MCS of 9 is shown, that means you need a minimum SNR of 40dB. Your SNR is only 10dB but you have a throughput of 907 Mbps.
These values don’t fit.
That is very strange, I am like 20 feet away and I have full 5GHz signal from my Flint 2 on my laptop, and the signal values are -49 for 2.4Ghz and -70 for 5GHz (with a concrete wall in the middle)
I would say this is a software issue, and like I said before the range could be better on this router, I don’t think it is transmitting at 1000mW. I hope this can be optimized.
Another strange observation. LUCI says that the signal value is -60 and macbook apps “Wifi Signal” and “Wifi Explorer Pro” say -87. I have a couple of other 5 GHz routers, they all show strong signal in my macbook, only MT6000 shows bad signal.
