Hi, bufferbloat is quite tricky even with just a single Zoom call.
Also placing 5G antennas, and identifying if they work correctly.
I’d like to see what Netgear does, having sqm settings as checkbox in the GUI, and fully automated auto-sqm (very good with busy 5G reception, always maximizing the available bandwidth).
If not automated, let’s give the user best practise settings for the relevant interface.
My 5G settings are:
Expand sqm config
config queue ‘rmnet_mhi0’
option ingress_ecn ‘ECN’
option egress_ecn ‘ECN’
option itarget ‘auto’
option etarget ‘auto’
option verbosity ‘5’
option qdisc ‘cake’
option script ‘layer_cake.qos’
option qdisc_advanced ‘1’
option squash_dscp ‘0’
option squash_ingress ‘0’
option qdisc_really_really_advanced ‘1’
option eqdisc_opts ‘nat dual-srchost’
option linklayer ‘ethernet’
option linklayer_advanced ‘1’
option tcMTU ‘2047’
option tcTSIZE ‘128’
option linklayer_adaptation_mechanism ‘default’
option debug_logging ‘0’
option iqdisc_opts ‘nat dual-dsthost ingress diffserv3’
option interface ‘wgclient’
option tcMPU ‘88’
option enabled ‘1’
option download ‘250000’
option overhead ‘92’
option upload ‘150000’config queue
option ingress_ecn ‘ECN’

I suggest to add to the graphical WWAN connection quality tab this info, seperated into 4x4 MIMO:
Expand AT commands 4x4 MIMO Quality
AT+QSINR?
+QSINR: 8,10,-32768,-32768,LTE
+QSINR: 29,27,27,30,NR5G
OKAT+QRSRP?
+QRSRP: -85,-85,-140,-140,LTE
+QRSRP: -61,-74,-72,-64,NR5G
OK
