Sorry for the delay, but I've been testing and using Kong's R7800 DD-WRT builds for nearly 2 months.
For the iperf3 tests, I installed @hnyman build r5442.
My HP Pavilion dv7 laptop iperf3 server is running Ubuntu 16.04 LTS and using an Edimax AC1200 Wi-Fi adapter that is about 3.5 feet from the router.
The router Wi-Fi is set to AC 80 MHz bandwidth, channel 36, security WPA2 PSK, and tx power is 15 milliwatts.
Find the list of TCP congestion algorithms and the default one:
I'm running the latest build on the R7800. I have a question about DHCP relay. I have two R7800, Router A is the DHCP server for my network and connects to my cable modem, Router B connects to just one wired host and one wifi host (GamingPC and TPCast for the HTC Vive VR HMD). The problem is I can't get Router B to relay DHCP from Router A for those two hosts. I've tried just about everything in the GUI. I'm wondering if this is a bug in the current build or I'm just missing something.
I ran this exact scenario sucessfully with a slightly different configuration of routers before (DIR-825 with DD-WRT as DHCP server, two Apple Time Capsules in bridge mode relayed DHCP from the DIR-825 quite well). Perhaps a simple way to enable a similar bridge mode would be valuable, I feel like it is a common use.

I am currently running with cryptodev enabled and have improved openssl speed results for >16 byte blocks. Have you considered enabling this?
Secondly I have been looking at the PVS table for ipq8065 to try and undervolt the router. I've simply copied the values for PVS bin 6 to 4 and compiled Is there any way to verify the voltages and what is applied?
Probably no way to check this using current setup, but you can add some printk into the code directly so it just puts output into dmesg. But I wouldn't bother because as far as I know it doesn't have some kind of fallback mechanism and it just uses values provided in DT.
I've not had time to fully test apart from the openssl speed test but imagine the speed improvement won't be all that great in openvpn due to overheads.
For the undervolt attempt, the reason I am sceptical is that even with the voltages set well below the defaults for pvs bin 4 in the dtsi file i have yet to experience any crashes, using 2 R7800s. Will investigate further.
ok @dissent1, well done. You've got to be pretty proud of this fix. Well, if you knew the number of people I had working on it and FINDING NOTHING you would be proud. Really cool.
Actually tnx to @Ansuel , his msg was a last drop to check that 0071 patch, guess no one had thought that there's smth wrong.
Check this commit. This one was a real pain to find - u-boot uses 2 last MiBs of a memory region for its own needs thus corrupting other processes that also write there. It is not mentioned in GPL sources or at least was perfectly hidden.
+1 one for that one.
That would totally explain every single issue I have with my TP-Link C2600 (IPQ8084) and my 250/20 Mb connection. I've been asking about this a few times on the forum and I never came close to even narrowing down this issue.
Please keep in mind that this problem (the performance one) has been raised in this thread a few times and around this forum many times more. They've just been disregarded and never linked together. Saying it's an issue with bad cable is just wrong.
