I work on 4G routers and the bufferbloat is very present on this ty= pe of link (4G). I contact you today to find out if people have experimente= d with solutions on this type of link or have configuration suggestions, be= cause the classic fq_codel or piece_of_cake and pie do not allow to fix the= bufferbloat.=0A= =0A= This is actually my own situation at home. My solution is to insert Cake s= hapers on both upstream *and* downstream directions, and adjust their bandw= idth settings according to variations in available 4G speed. To do this I = use an IQrouter, which is basically a TP-Link Archer C7 with custom firmwar= e.=0A= =0A= One of the difficulties with 4G in particular is that the link capacity var= ies a great deal according to both radio propagation conditions (weather, o= bstructions) and local usage by other subscribers. That means the right ba= ndwidth setting for the small hours of the night, when nobody is awake, wil= l leave you with a lot of bloat in the evening, when everyone is both awake= and home from school/work. You will need to measure these trends and set = up a bandwidth schedule accordingly.=0A= =0A= - Jonathan Morton=0A= _______________________________________________=0A= Bloat mailing list=0A= Bloat@lists.bufferbloat.net=0A= https://lists.bufferbloat.net/listinfo/bloat=0A=
