I typically do as well, but I want to see and evaluate the lack of accuracy report first before jumping to conclusions. Especially since you did not observe this yourself but only relayed information from a forum post, and 3rd hand information is sufficient to raise flags, but not enough to declare that speedtest unreliable. So far for me it worked reasonably well and the results compared well to flant rrul/rrul_cs8 runs of around the same times, so for me it seems to work okay (but that in itself is also not proof that it is issues free for everybody).
I guess what I want to say is, I take your report serious, but reserve judgement until I did some research.
This is what I am probably going to end up doing. Just sad I won't be able to use the firewall, which is why I installed LEDE over my original firmware in the first place.
He should be able to gain access to the modem gui if it's in a diffrent subnet...
See: [SOLVED] How to access the modem (which is in bridge mode)? - #11 by angelos
It's quite easy and you can set it over Luci... i have a similar setup with a modem working in full bridge mode, but i dont think that will make a difference.
Than put it in a diffrent subnet or put ur WRT1900ACS in a diffrent one...
Best would be to put the modem in bridge mode, but i dont know if will work with your device and your ISP.
You wrote somewhere that you are not able to access your modem gui because you dont have the admin login... is that still the case ?
I would kill my ISP if they wouldn't allow me to access the modem and change IP's/Subnet or add static DHCP leases, change Wifi pw aso.
uhm.. i could not live with that ISP. I dont know what you could do else...
In my country they have to give you the credentials and you can always use your own hardware but they won't give you any support for your own hardware, which is understandable.
Imho it should be your right to use your own hardware but i think that differs from country to country (or from ISP to ISP).
And the factory firmware worked better for you in terms of bufferbloat/QoS ? Somehow I cant believe it...
If you ever change your ISP make sure they will give away your internet credentials and allow you to use your own modem.
Why are you thinking that it's a requirement to put the ISP router in bridge
mode? you always have to deal with an upstream router that you don't control and
that can have bufferbloat problems, it doesn't matter if it's the one in your
house or the one at the central office on the other end of the wire.
It just means that you may need to sacrafice a little more bandwidth to get good
latency.
The poster has had settings that greatly improved his latency under load (the
bufferbloat). Is that improvement not sufficient? or what is the remaining
problem that needs to be solved?
Okay, so my trawl though the dslreports forum did not reveal a smoking gun that would convince e that the speedtest is consistently flawed; though there is enough to show that the test should also not be blindly trusted. Personally I am still of the opinion, tat this test is still the best "standard-type" speedtest that I will recommend for people starting to look into bufferbloat issues, with the caveat that measurement should be repeated before being accepted. Thanks for the pointer.
