[GCC 7.2 BUILD] Optimized TP-Link Archer C7 V2 AC1750 LEDE Firmware

Wow! this thread is pretty long now!

How can I tell with version of r00t's firmware I'm running?
My status page shows "LEDE Reboot SNAPSHOT r5464-5a8e9846af / LuCI Master (git-17.342.53118-6d086bf)"

Also, is r00t planning on release future releases? I couldn't tell by browsing through this thread!

thanks

I'm using my Archer C7 v2 as AP (not as router), the only way to improve performance in Wifi/LAN is overclocking via breed u-boot. Checked by myself.

After overclocking from 720 Mhz. to 1 Ghz. I've improved my connections about a 30% (the difference between 720 and 1000, about a 30% in Mhz.)

It's supposed NAT will improve as well after overcloking, but as I told before, I'm not using it.

Thanks,

i think most people are using his config file and patches etc now and building there own images mostly, or just keeping his as there stable version. Who knows....

856

where did you notice the change in performance does your kernel log still say 720?

857

Yes, I noticed about 30% more in performance (checked with netperf util).

Thats what my kernel log shows:

[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
[0.008512] Calibrating delay loop... 498.89 BogoMIPS (lpj=2494464)

Wright now, I'm not using @r00t firmware, I'm using latest LEDE snapshot.

858

is this the method you used to overclock it, from this thread?

I see people that bricked them in the process of overclocking, after flashing breed u-boot...

859

Yes.

In my case, I had no problems. Working like a charm.

860

idk why mine isnt overclocking then, strange...i mean breed is there and keeps the settings, just the kernel isnt accepting them or something. Interesting.

Updated today, and still working:

862

Maybe I’ll try reflashing

863

can you show all your kernel modules? maybe theres something im missing in my build.

Hello .

I have a problem and would like to know what happens.
I have a ./fslb file that works perfectly on ar71xx AC 1750 with Latest Chaos Calmer Release - OpenWrt 15.05.1

But now I've upgraded the router to LEDE with gcc 7.3 and the file does not work.

Error
Without chmod I do not have permission.

With chmod + x fslb or chmod 777 fslb there is no error, however ./fslb not found.
./fslb not found
with cmd ls o fslb is in the directory.
What happened ?

866

Have you upgraded to this specific community release or to an official release available on downloads.openwrt.org?

867

i fixed it, after making my frequency setting changes, rather than pressing restart i just unplugged the router and it booted normally!!

868

have you seen any real world improvement after overclocking to 1000 mhz in comparison to the old value?

869

you know ever since i added a few things to my build, i was getting better performance as it was, but now that i have the overclock engaged im getting another 10-20% better on download. i was only getting 115 mbps download tops to start with on this router, now since my firmware and the breed overclocking my download is 135 mbps.

870

Yes, about a 30% in performance.

871

What's your max download? 135Mbps max is terrible for this router. It should be capable of 800Mbps-1Gbps with no need to overclock if you look at a review like this:
