Netgear R7000 - first installation, first problems

    Hi all, I've just upgraded to the R7000 from my old RT-N16 and have reconfigured the device as the old one (more or less). Thanks Shibby for the very hard work you're putting into this device and in tomato in general!

    I'm running Shibby 120 AIO and did follow the installation video step by step (btw Shibby might I suggest you summarise the steps into a text howto? A video is not always the best way to inform in my opinion.

    Any ways here the first 4 points:

    1) Despite the R7000 has been set with pretty much the same config as the old Asus, this R7000 takes at least double time to reboot. Yes the image might be bigger than before but the CPU is also 4 times as fast. I'm not complaining! I would just like to make a point as it could be a simple bug? Perhaps not?

    2) Most important: Ping to google.com latency went from a steady 8-15ms (7~8ms jitter) to ... banana! Please see the ping from the R7000 to google.com

    3) Not a problem at all, but just to clarify my mind: As the R7000 is everywhere published as dual core 1GHz, I would have expected to find the reference to two CPUs under /proc/cpuinfo but that's not the case:

    Code:
    cat /proc/cpuinfo
    Processor  : ARMv7 Processor rev 0 (v7l)
    processor  : 0
    BogoMIPS  : 1998.84
    
    processor  : 1
    BogoMIPS  : 1998.84
    
    cpu MHz  : 1998
    Features  : swp half thumb fastmult edsp
    CPU implementer : 0x41
    CPU architecture: 7
    CPU variant  : 0x3
    CPU part  : 0xc09
    CPU revision  : 0
    
    Hardware  : Northstar Prototype
    Revision  : 0000
    Serial  : 0000000000000000
    
    4) I did configure my tomatoAnon preference but under overview I still get:

    You did not configure TomatoAnon project setting.
    Please go to TomatoAnon configuration page and make a choice.


    Thanks!

    Forget about point 4 I have now resolved that.

    On point 2 instead I can confirm that the ping from the my laptop to the router (Ethernet) is crazy as well. I'll check the cable but the old router was responding always with less than 1ms.

    I restored the netgear firmware and the ping went back to 1 ms for the LAN.

    Re-did everything from scratch (initial firmware, 119 or even 120, same result, the ping within the LAN goes to an average of 50-60ms.

    Beside this, after having configured manually (no nvram export what so ever) this is how my network configuration page looks like :-/

    Where towards the end of the page I get:

    I have installed RAF 1.13f, with a really basic config this ping latency is also appearing. Perhaps a bug in the core ARM code? I can't think of anything else considering Genie doesn't have this problem.

    And jumbo frames don't seem to be working.

    Is it only me experiencing all these problems? If so I need to send the unit back and get a replacement ASAP.

    Please let me know if I'm missing anything here

    Thanks!

    1) it`s issue and is not. I don`t know why it is happend but it is. I didn`t find solution yet and i didn`t know is the any solution. I checked AsusWRT on RT-AC68U and it also boot up ~3mins. The most important is that router works :)

    2) know that issue and i propably found solution. today i put v121 to my R7000 (ip 10.1.1.1) and my ping are now stable:
    3) speed is taken directly from kernel. On AsusWRT (RT-AC68) is also showed 2x 1598MHz, not 2x 800MHz. It`s only cosmetics. We all know that CPU speed really is. I will try to change sysinfo and grab cpu speed from nvram (clkfreq), not from kernel. We well see :)

    4) forgotten ;)

    Was all in the ARM or Tomato(Shibby or Raf) thread :D... I have the same Problems :D

    Hi Shibby

    I have the same problem with ping latency. I use 124 release in Netgear R7000.
    When i ping my gateway the latency go to 5ms to 1000ms.

    Have you any idea to fix it ?

    I couldn't have the network working that way so I sold the R7000 on ebay and bought an ASUS ac56u.
    I can confirm that for what I'm doing I don't see any performance difference between the two models.
    Both extremely fast.

    I really hope R7000 users will get the solution to this puzzle very soon!

    I and at least one more from here tried to squeeze the solution out of the DD-WRT devs but they didn't give a nibble of information, other thatn to say it was solved long ago. It's been reported that Netgear and Broadcom came up with a kernel change solution to fix the R7000. I have been trying the latest DD-WRT nightly builds for a few days, using a new Broadcom driver and can report that pings are normal and power levels are outstanding (much better than Tomato sadly :( )

    Thank for your responses.

    rs232 : Can you confirm that everything works on your asus router? Wifi 2.4/5 Ghz, QoS, vlan....

    I can confirm that the ping issue is not there (I've been running tomato on ad56u for about 2 months now).
    There are though all the other current ARM issues like bandwidth monitoring not working just to mention one.
    I do use VLAN, QoS and 5 GHz and they appear to be working fine.

    The only issue I have noticed is that the router gets stuck randomly and occasionally I need to manually reboot (no entry in the log what so ever). I suspect this though to be a peculiar part of my config as I've never heard any other ac56u complaining about this before, so I can't confirm this to be a real issue.

    Please remember, despite the great effort from the mod developers, ARM builds as per today are still beta.
    If you are looking for reliability stick to MIPS for the time being, where if you don't mind an occasional power cycle and you like to enjoy higher performance, ARM is a very good option.

    I am looking for an ARM router with Tomato Shibby as stable as possible.
    I can't find any information about the ping problem. This problem is in ping protocol or for all the network layer ?
    Your feedback is verry precious for me.

    Thank

    The ping problem is specific to the Netgear R7000 only. The issue is currently not completely clear but I suspect this does not relate to ICMP only e.g. other protocols might me delayed while crossing the device but latency measurement for other protocols is a bit difficult to measure.

    Being this issue R7000 only if you changing model you'll automatically get the rid of the ping and other potential latencies issue.

    I think I'll order the Asus router and test everything.
    Thank you for the time you have given to me. I can progress in my work.
    I will make a comeback

    Thank

    Hi

    Have you build your own TomatoUSB Shibby or use the firmware build by Shibby ?
    In the sources I don't see "ac56u" target. I cant use "ac68u" target and use the firmware in ACR68U router ?

    Thank

    Adrien
