I received my 88u today. Bought it from Amazon but I think that was a mistake. It looks like it region locked in some way. With my 87u I had 5 GHz channel 36, 40, 44, 48, 52, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140. Now with the 88u I have only channel 36, 40, 44, 48, 149, 153, 157, 161.
Is there any way to change the region on the 88u so I get the correct channels?
First thing I did was install the 3.0.0.4.380_858-g32ea84e release and make a WPS reset and factory reset from GUI and enter all settings manually. In my setup I have two 68U routers set as repeaters to the 88u, one of the repeaters are about 200m away from the 88U. The problem I have now is Linkspeed to this 68U repeater. It seems like the 5Ghz radio is not as good in the 88u as in the 87u or maybe it’s a software issue that is going to be fixed.
I have one big high gain antenna on the 88U and one big high gain antenna on the 68U repeater. With the 87U I had about -63dbm signal level and 433Mbps Linkspeed. With the 88U I have -78dbm and 117Mbps Linkspeed. The only thing done is to replace the 87U with an 88U in the same spot. The big antenna is fixed mounted to the house so it’s not moved. I only moved the antenna cable connector from the 87U to the 88U. I have tried to put the big antenna on all 4 antenna ports but it seems like the one the right side gives the best signal level for some reason.
For now I will probably put my 87U back despite all its flaws but it works well enough – I have the correct 5 GHz channels and it gives me 433Mbps to my repeater. If someone has any ideas how to fix the channel and Linkspeed problem let me know.
