@mrk26 You are having fun, let us know how you applied cap (cmds) and do please keep us all updated
Well is a bit of fun with positive results at the end :D
First cap applied to 50 Mb/s with command: bcm_xdslctl configure –maxDataRate 50000 20000 100000
First number is download, next upload, third don’t touch :P
Modem will re-sync straightaway once you hit “enter”, to remove cap you need to reboot modem, this command will survive re-sync initiated by DLM . I read somewhere that for DLM pleasure shouldn’t be more than 3 FEC/s, that will give easy calculation. I will check after a 1 hour, 12 hours and 24 hours. If i will fit with above calculation I will not cap any further just wait for DLM to remove interleave on downstream.
Once again thank you @UK Sentinel for this ability.
P.S
All credits to guys from Kitz forum for tips, i just figure out correct command after playing a little bit with these from other forum.
P.S2
Before somebody place any funny comments about playing with these as provider may don’t like it I would like to say that they don’t like for people play with reducing SNR, in this occasion I increased SNR to make line more stable, hope will be helpful for somebody else.

August 9, 2019 at 3:03 pm #3751No problem and thanks for taking the time to post cmds etc. hopefully this will reduce FEC and get you on Fastpath (Downstream)
Just as a side thought, now you have capped your synch speed, you are probable synch same as you would on your ECI modem ?
Will be interesting to watch the FEC’s going forward and see how they compared to the ECI modem ?

August 9, 2019 at 3:34 pm #3752Well sync speed is untouched so still sync over 83Mb/s which is higher than ECI, just download speed is capped now which is at the moment lower than on ECI, but now in 1h 42m i got 8391 FEC errors which is like 200k less than before (and I try to keep below 10800 FEC/h, which is working at the moment). If this will take effect in next 5 days by remove my interleave and jump on fast patch I can pay that price of lower speed for couple days ;)

August 9, 2019 at 3:42 pm #3753I see, so in effect you have applied a QoS type cap of actual download speed, does not the DSL-AC88U have this option via UI (Traditional QoS) ?
My DSL-AC68U is not plugged in currently to check ?

August 9, 2019 at 3:43 pm #3754Been playing with other setting too :P
If somebody still got problem with disconnections on wifi is worth to change “Group Key Rotation Interval” to 86400 (in my router is same as DHCP lease time), problem gone immediately.

Well I was thinking about this but in my previous router RT-AC86U I was able to cap every device individually which may help, this one don’t have this future. However with this method you raise your SNR which actually make line more stable and reduce amount of FEC errors where QOS will not give more stability to the line.
Update:
2 hours and FEC is 10531, so in theory half of this what should be O.K for DLM, could cap bit higher :P

August 9, 2019 at 4:01 pm #3758I am sure @jOhn at Kitz knows what he is talking about and gave excellent advice .
Shame the DSL-AC88U does not offer this basic level of bandwidth capping, as this could have worked also (maybe) and saved you a great deal of effort ;-)

August 9, 2019 at 4:11 pm #3759Yes @jOhn was very helpful in this occasion, I just needed fw with unlocked telnet to do what modem suppose to do in first place. Unfortunately Broadcom limit option to play with SNR settings for VDSL, shame that they didn’t think about positive way of using it or at least give ability to increase SNR rather to decrease. Not sure if ASUS is able to add SNR control to the UI (increase only) I think that maybe a mission for you @UK Sentinel to ask Asus and convince them about positive output. :)

I have tried , but they are limited by what Broadcom will allow them,ย it is on my list ;-)

August 9, 2019 at 7:51 pm #3761Quick update after 6h up and running, so far looking good for me, not even half of this what was after DLM reset last night from previous screenshot, and by simply calculation looks like I’m way below 3 Fec errors per second. Hope DLM appreciate my effort :P

August 9, 2019 at 8:09 pm #37644800 FEC per hour, a big reduction – let us know if/when FAstpath kicks in for Downstreamย after the next re-synch ;-)

Downstream looks clean.
Upstream, on the other hand, has 153 CRC errors, resulting in 138 Error Seconds, over 6 hours.

August 9, 2019 at 10:12 pm #3767Well, upstream is already on fast patch so don’t bother me at the moment. ๐
Update:
9h 22min and 57984 FEC errors, still way ahead. ;)
Today 10h after re sync was over 322k (before cap applied), to say a lot different is not enough….

I read a little all over and looks like fw for DSL-AC88U is based on Openwrt Chaos Calmer 15.05? So why Asus don’t pull all what is good from it? For example ability to chose between shh and telnet, add password protection to telnet, block automatically acess to telnet if admin password for router not changed from default, more accurate and detailed dsl stats already in UI and so on..
If you are in good relation with them (at least they consider some of comments) maybe is worth to ask why they don’t pull good parts from sources they use, not that complain (a lot ;) ) but base on other people complains Asus could do better for top shelf (price) device like they try to do for routers. (my previous RT-AC68U was my best investment for years, changed to 88U for better wifi and standalone device, and few more futures on paper :P )
Finally if they can’t make proper software why simply don’t pay for somebody (apparently board manufacture is Arcadyan) to make software working properly and just add Asusu GUI to it?
BTW
22h 16min and 103644 FEC errors at the moment :D
