E4200 on Tomato victek - reboots with 5Ghz

Discussion in 'Tomato Firmware' started by jitha, Aug 19, 2013.

    Hi,

    I have flashed my E4200 v1 with tomato - tomato-E4200USB-NVRAM60K-1.28.9013MIPSR2-R1.0--RAF-VPN-NOCAT

    When I enable 5Ghz the router reboots frequently (every 2 or 3 mins). I had tried toastmans version as well, and had the same problem. Should I be doing any specific configuration in advanced wireless or some other location to get the router to work stable when on 5Ghz?

    If I disable and just be on 2.4Ghz the router does not show this instability.

    Any help will be appreciated

    RAF version used? I'm in beta releases and latest version is 'y' please report.

    What's your configuration?
    QoS active? Y/N
    BW Limiter? Y/N
    Wireless settings by default?
    USB connected? Y/Configuration, N

    please post it. Thanks.

    Edit: Wireless card model used and driver version if possible is welcome.

    Yes RAF Version - but not beta - its this file (tomato-E4200USB-NVRAM60K-1.28.9013MIPSR2-R1.0--RAF-VPN-NOCAT) i downloaded from the location - http://victek.is-a-geek.com/Repositorios/TomatoRAF/

    My configuration is mostly default :- Details here of the changes done (is there a way to pull out the configuration specifically?)
    5Ghz, wireless mode - auto, Channel width 40Mhz
    No QOS, No B/w limiter
    B/w & IP monitoring enabled
    From the status page the system info is:-

    Hope all this helps to let me know what could be the best config to keep my router stable with 5Ghz enabled

    Does it reboot like that at the stock CPU speed? (480MHz)

    Unrelated to your issue (possibly), consider changing the following:
    - switch to Victek's latest 'beta' (it's pretty well a production release and has many useful updates)
    - change 5GHz mode to n only
    - change 2.4GHz channel to 1, 6, or 11

    this link leads to -http://victek.is-a-geek.com/Repositorios/TomatoRAF/
    for beta I should be using this link right - http://victek.is-a-geek.com/Repositorios/Beta_RAF/

    Thanks Marcel for your response as well, i will try that config out.

    Apologies victek, your link was fine, my browser was caching, so was taking me back to the regular tomatoRaf folder instead of beta :), i will check it out and keep you all posted

    Don't worry, it happens ... please make a nvram reset when selecting the update to this version. Let the unit with default settings and everything will work smoothly ...

    Thanks!

    Victek, i installed - tomato-E4200-1.28.9013MIPSR2-RAF-V1.1y.bin
    I did a full flash, did a 30-30-30 reset, and then configured back my settings.
    Still the issue exist :(. The router reboots when 5ghz is enabled, i have set it to N, and also tried the 20Mhz option instead of 40Mhtz, still no luck. Actually now it reboots very frequently.
    I disabled 5Ghz and then no reboot issues at all.
    Also in the advanced -> wireless area, i have enabled frameburst and preamble as short for both (2ghtz and 5ghtz).

    Rather than 30-30-30, please do thorough NVRAM erase from the Administration section. Leave advanced settings on default.

    jitha Reformed Router Member

    yes Marcel, i did do a NVRAM erase from the upgrade section under administration, then reconfigured still no luck :(, issue still persists.

    The ruter reboots when some device is connected to 5GHz band? then, what wireless card is build in your laptop or mobile device?
     
  13. jitha

    jitha Reformed Router Member

    The scenario is like this, one the router is up on 2.4 and works fine, i go and enable 5ghz, as soon as it is enabled and router comes back up (my apple laptop connects to the usual 2.4, as that was the last connection). Now even before i try to connect to 5Ghz the router reboots. I was not able to connect to router itself after enabling 5ghz, so i had to remove the WAN input (Comcast connection from modem to router), then router remained stable, so i could connect and disable 5Ghz.

    I found out yesterday that router is stable with 5G, if the WAN input is removed.

    Hope this gives an idea of what i am facing.

    Very useful information, this issue happened to me also in E4200 when I was enabling captive portal and as you described the router reboots and after unplugging WAN I was able to access the router again and disable captive portal, however I'm not able to reproduce the issue with my laptop connected to 5GHz wireless, could you investigate the model of the wireless card equipped in your apple laptop?

    Thanks!

    Thanks... I will investigate this issue with some friend apple laptop, can't reproduce with Intel 5xxx, 6300 wireless card ..

    I have a netgear wnr3400 on dd-wrt connecting as a repeater + belkin as a repeater (n600) + roku 2+ Acer windows laptop. I am going to shut all the devices and try one by one to see if I can isolate if it is a specific network card. I will post you the info (if i find out anything specific). I will do this once i am back from work

    This has come into my mind, because the router rebooted today (just n 2.4Ghz), when i was playing netflix on roku 2.

    I think i have found the problem. Router was very unstable this evening, so I did a lot of experimentation.

    The real irony is, i dont think it is related to any configs or firmware. I had an old linksys WRT54G2 router, and when i got this router E4200, i assumed that the AC adapter would be same and ended up using the old AC adapter :(. Looks like that could have been the culprit, so finally (after all wireless devices trial & error) i compared the ratings of the adapter and they were not matching. So i just pulled off the old one and put in the E4200 adapter, and now it looks like the router is stable.

    Apologies to all for the back & forth on a mistake done due to laziness :(.

    If it gets unstable again I will let you know (I am hoping not, and hope to have stable stuff now).

    One sideline question, is there a RAF firmware that i can use for WNR3400
     
  19. Victek

    Victek Network Guru Member

    Good finding @jitha you saved me a lot of time to find reason for this behavior, probably the current supplied by the AC adapter used by WRT54G2 router is not enough for the E4200.

    What version for the WNR3400 ? V1-V2...
     
  20. jitha

    jitha Reformed Router Member

    Right Vicktek, thats why I wanted to get back and let you know that I think I found the problem. Also looks like the current needed when the WAN connection is provided is higher than when the WAN connection is not there, because as I said before when i remove the WAN connection, it was not getting recycled.

    Now the router is really solid, earlier i could not use 5ghz even for 2 mins, now the router has been up wihout getting restarted for around 13 hrs and I am on 5Ghz :).

    I have WNR3400 V1
     
  21. Victek

    Victek Network Guru Member

    The upgrade procedure for this router (WNR3400) suggest to have a closer serial connection... do you?
     
  22. jitha

    jitha Reformed Router Member

    no i dont have a serial connection :(, i have dd-wrt on it at present, would that help?
