Any experience, I tried succesfully 30MHz channel, which gives 195Mbit of layer speed and approc. 150 Mbit of net speed. I was trying to do 60MHz channel but no succes at time..
Tried on RB751G HW, ROS B2
software-id: TIXX-28XX
upgradable-to: v7.x
nlevel: 4
features: extra-channels



Anyway known bugs for me:
1/There is missing offset value in Winbox and Webfig menu, even if it is set, which is not fun, as I enjoyed it fully in v. 5 at least on winbox..
2/Once changing channel setting it disconnects WB

Here is list setting, 2332_30 works fine, but 2332_45 wont work at all saying: Unsupported channel and in-scanlist unsupported channel


0 list=test1 name="2332_30" frequency=2332 width=30 band=2ghz-onlyn
extension-channel=below-control

1 list=test1 name="2332_45" frequency=2332 width=45 band=2ghz-onlyn
extension-channel=below-control

width=30 is the max value and since you are using extension channel you are already using 60mhz (2x30mhz). Maybe it isn't working so well so try to lower the width to 29, 28 or even little lower.

Ok I will do that later today, but it seems it wont to expand at all. I will try it later

Just confirming, the only setting working on 751G is 30MHz channel, but even then it wont work on expansion channel.. unfortunately so the best I am getting is "only 195Mbit MAC layer - it is 5 km link"

60 Mhz ? Do I miss something? I just installed ROS6 on a 493GAH with a R52n. But I do not get a 30 mhz width. I only see channel-widht and the max is 20/40 below or above.

insider pls confirm this
features: extra-channels (do I need this)
cos after 5.x ver. super-channel features is free or extra-channels is something else
I have a problem when selecting 30Mhz channel width (on RB800 its with license Lv6) that my license level doesn't allow it (only 5,10,20,40)
Hire is another post for that

pls for info.
Tnx.

you need to have superchannel license to use those custom channels - please write to support@mikrotik.com.
