I tried that. Didn't made a dent.
With SQM cake I can only get 30-70 Mb/s out of 250 Mb/s available.

Here is a bit of required "massage" for Archer C2600 18.06 release image...

Thanks for the info @sjanulonoks ,
Still loosing about 50% of bandwitch using cake.
In my opinion, a dual Core 1.4 Ghz. should be able to handle it (300 Mb and much more).
My old Archer C7v2 (single core 750 Mhz.) was able to manage an 300/300 Mb. fiber connection with SQM ON.
Many thanks for sharing your info!!!!
This "loss" - as you say comes from ISP BufferBloat mostly
Main point of CAKE - to have a reasonable balance between connection and latency.
I don't think so. In my opinion OpenWRT in C2600 is not working properly (performance problems).
Less powerfull routers than C2600 can manage more SQM speeds.
Absolutely not true.
Right now on 17.01 I can get over 200 Mb/s with SQM ON.
On 18.06 I can't really get 100 Mb/s with cake.
I don't know what they broke but in my case even software HW NAT (enabled in firewall) doesn't help.
Wondering your settings were on your C7? I never got close to that w SQM on on mine. Should go off thread, but wanted to get a quick one in there....
My C7 v2 was able to reach about 250 Mb. with SQM ON. Now is running as dumb AP.
Have you tried lastest versions of 18.06 in your C2600)?
My C2600 is running stock firmware waiting for better times in OpenWRT/LEDE.
My C7 v2 is running (now as AP, before as router) overclocked to 1 Ghz.
[ 0.000000] Clocks: CPU:1000.000MHz, DDR:760.000MHz, AHB:380.000MHz, Ref:40.000MHz [ 0.000000] clocksource: MIPS: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 3822520893 ns [ 0.000005] sched_clock: 32 bits at 500MHz, resolution 2ns, wraps every 4294967295ns [ 0.008501] Calibrating delay loop... 498.89 BogoMIPS (lpj=2494464)
what about delay loop? varies among different architectures? note that 24KC OCed to 1GHz is 666 BogoMIPS. what OC method did you use?
Ah, overclocked.... Another question, were you look at top, and checking for 0% idle? Mine at stock speed would deliver up to 250 or more, but with it hard on 0% idle, throttled back to 120-140 would leave a bit of resources.
Now, with 18x.x, or even 17.01.6, it seems like that's dropped to 80-90 over the wifi.... but that's another mystery
I'm running LEDE 17.01.6 and I haven't seen any wifi speed decrease.
My AP is working like a charm. (5 Ghz. band).
Take a look here: [GCC 7.2 BUILD] Optimized TP-Link Archer C7 V2 AC1750 LEDE Firmware
How about you C7 guys create your own topic.
On topic, I'm running latest git and maxing out my 350/350 Mbit internet connection without breaking a sweat.
If you would like to try my build have a look here: Optimized build for the TP-Link C2600 / Netgear R7x00 / Linksys EA8500
Not really, no.
I'm still on 17.01.5 - that's my own build.
Well, have to say I misspoke, after thinking back it was only the 18 release that performed much slower on eth and wifi.
17.01.6 is noticeably slower also, under my eternally variable cable connection, as the home router/NAT/AP. But more like 10-20%, not 40-50%
And, my apologies to the group, I was responding to Klingon thru email, and not realizing it was being echoed in the forum.. will watch for that from now on...
