hi friends. i have nanostation m2 whith Ar7241+ar9283 +awl6153 per chanel.
i try from chaos calmer to the last builds. the problem is similar to all builds.
now nsm2 work as wr842 v1 or mr3220 but it does have no matter.
in air os works well. its inportant because hardware is ok.
i have do this
- make backup of art 64k and full flash.
- I solder usb port for lte modem, now lte works fine and i have around 70mb/s and will use mwan3
- I solder IPX conector for 2 separate antenas whith 27dbi gain.
- in spi flash i flashed breed bootloader and flash openwrt and art part.
- i have resolder some gpio pins like reset pin and wps.
- config openwrt
wan(wlan0) is client mode connected dhcp ch7 ht40 bitrare 180-300
wan2(eth2) is lte modem in ndis mode.
mwan3 i use wan_wan2 rule.
My problem is router have big load avarage more then 10 8 8 and speed is low because cpu have big load but run in terminal there no procces whith high load. In clean System i have same probem.
the i have find another board is air grid m2 there radio is ar9285 there aro no problems in same config . grid have just one chanel so it work max in mcs7. and speed is bit lower.
then i tryed bullet m2 harware is same as ns m2 but in bullet work radio just one channel of ar9283 bu it have 2 chanells.
i tryed to flash in ns m2 art parition from bullet m2 . there no lags cpu load is 0.1 0.2.0.1
in a first time i was very happy. but work just one ch.
i tryed other art but stiil no changes.
in 1x1 work well
in 2x2 few minutes work well then apear load in cpu. i think is driver loads cpu.
