E3200 with shibby latest build, 5GHz disappear after reboot

    I'm on 116 right now, and I've already tried 109, 112, 115, all with the same result.

    I've Google'd this for a week and found nothing like this.. although there are some similar cases but the resolutions don't work here.

    This is what I did with every flash:

    1. Do 30/30/30 reset
    2. Flash firmware
    3. Clean NVRAM (thorough) [well, just to make sure]
    4. Boot up.

    When the router boots up the first time, everything seems to work. And if I reboot without changing any settings, 5GHz interface (eth2) still shows up.

    I tried just to change the AP name for both interfaces and reboot, it still works.

    However, after I've set up the router and reboot, 5GHz is gone. These are the settings I've tampered with:

    1. DHCP range (from 192.168.1.10 to 100). My connection is DHCP which obtains IP from another router.
    2. Changed both wireless interfaces' name, encryption. Channels set to Auto, both using 40MHz bandwidth, upper control sideband.
    3. Changed router Identification.
    4. Static DHCP entries for 8 machines.
    5. Checked "Mute dhcpv4/v6/RA logging". Included a dnsmasq config of mine via conf-file option.
    6. USB stick plugged in, mounted /dev/sda1 to /opt, /dev/sda2 to swap
    7. OpenVPN Client 1 & 2. One is TUN via TCP, another is TAP via UDP.
    8. PPTP Client
    9. Administrative options, like SSH keys, TomatoAnon, Monitoring and Logging, Scheduler and Scripts.

    The 5GHz interface disappears right after I've completed above settings and reboot. Before reboot the 5GHz still works fine.

    And below is the dmesg from the router:

    IIRC the 5GHz interface on E3200 depends on some USB interface to work correctly. Is this why it doesn't work? And what could possibly cause this?

    Thanks guys.

    Had this same issue before. I just stopped relying on the 5GHz. Even if I got it working, transferring large data over it causes it to fail after a while, requiring a reboot.

    Koitsu mentioned it before.

    That is pretty critical. Some people use and depend on 5GHz. I would suspect the majority actually. Or what would be the point in having a dual band router? I find this alarming and never even knew about this. I need and use 5GHz. Does this exist in all firmware Tomato releases for 5GHz? I am currently using Victek's latest "x" version. Have had no reason to reboot it yet and hope I don't have this problem. I have a Linksys E4200 v1.

    The Linksys E4200v1 doesn't seem to have this problem, the one I have at home works just fine. Maybe the 5GHz interface doesn't work the same as in E3200.

    And it's very true that some of us depend on 5GHz very much, like the E3200 I use in the office. 2.4GHz bands are just too crowded here, it's lucky to just get 54Mbps via the 2.4GHz interface. 5GHz is much more available and stable for us, but unfortunately it doesn't work for some weird reason :(

    5GHz radio is different in the E3200 and E2500 than in the other Tomato routers. It requires an additional module that works under most circumstances but seems to fail with some particular settings combinations. I won't be fixed unless someone takes the time to test different setting combinations until something breaks.

    If i had to put any variables into suspect it would be most likely linked to USB, because the 5Ghz radio in E3200/E2500 is a USB radio, which is why it needs an added module compiled in to even work. Most of the cases which report these types of problems all seem to have a common factor - they use the USB port with some type of storage hooked up to it - and when they do is when the 5Ghz radio seems to disappear. Just my opinion..
     
  7. maddie

    maddie Reformed Router Member

    That's what I had in mind too, so I tried to remove USB, restoring settings on the USB Support page etc, but nothing seems to work..

    And it reminds me that something worth mentioning, this particular E3200 worked just fine before I brought it to the office. I used it as a wired switch + wireless AP (WAN disabled, bridged WAN port to LAN), and also it was hooked up with a USB hard drive which was used as a Samba share drive. 5GHz was working fine then.

    The only difference I can think of is that when it was using as a switch/AP, I didn't use DHCP on it, and no OpenVPN/PPTP Client was configured either. I'm wondering could it be the TUN/TAP driver that the OpenVPN uses somehow interfere with it? But still it doesn't make sense, since (if I understand it correctly) the TUN/TAP interface won't be initialized/added before the OpenVPN client is started, and the 5GHz interface should be initialized way before that. And I'm clueless.

    run "lsmod" and look is there "wl_high" module loaded. You can show us also "dmesg". USB bus may be overloaded. Try unplug all USB devices.

    Can you configure your router step by step and after each "save" do reboot? We have to figure out which settings broke eth2

    Yes, I will have to do that on Monday since it's weekend here :)

    I will report back as soon as I can! Thank you, shibby ;)

    The "usbcore" module is missing in your lsmod report, it didn't load for some reason

    Just checking, "USB Core Support" is checked on usb page, 5Ghz won't work without it

    maddie Reformed Router Member

    USB Core is definitely enabled, as I'm using a USB drive to install Optware.

    @shibby:

    Confirmed: Once I enable OpenVPN TAP, 5GHz disappears.

    OpenVPN Client 1: OpenVPN TUN -> Enable -> Reboot -> OK
    OpenVPN Client 2: OpenVPN TAP -> Enable -> Reboot -> 5GHz disappear.

    OpenVPN Client 2 settings:
    Start with WAN: True
    Interface Type: TAP
    Protocol: UDP
    Firewall: Automatic
    Auth mode: TLS
    User/Pass Auth: False
    tls-auth: Disabled
    Server is on same subnet: False
    Create NAT on tunnel: True

    Poll Interval: 5
    Redirect Internet Traffic: False
    Encryption cipher: Default
    comp: Adaptive
    tls-reneg: 0
    Connection retry: -1
    tls-remote: False
    Custom Configuration: Yes

    And keys.

    That's it.

    Thank you!

    I've got an E2500 v2, and I'm not seeing the 5GHz come back even after a reboot. I've just upgraded to the 117 release (but noticed the issue earlier today even without the upgrade). I had been setting up OpenVPN server, both a TUN and a TAP interface (until I realized iOS doesn't support TAP -- see my other posting here http://www.linksysinfo.org/index.ph...ith-openvpn-on-tomato-using-ios-client.69874/).

    How did you get the 5GHz to come back? Do I have to do a 30-30-30 reset and can I then upload my saved config? Or do I have to reconfig manually again from scratch?

    Thanks.

    Unfortunately, yes you have to reset your router in order to get 5GHz back to life. OpenVPN TUN works just fine, however TAP seems to cause problem. So if you're going to upload your saved config, make sure there is no TAP related configurations inside, or else the 5GHz will still disappear after reboot.

    Thanks, @maddie but it didn't seem to work for me. So before upgrading to the latest 117 release, I'd saved a copy of my config. Today I double checked my current settings, and there was no OpenVPN server or client enabled. The only thing I do have set up is a PPTP connection. So I just did a 30-30-30 reset and could see the 5GHz was showing up as enabled in the overview. I then uploaded my saved config and subsequently have lost the 5 GHz.

    I then also tried disabling PPTP and saving the config. Then did a full 30-30-30 reset and reload of the saved config, but unfortunately the 5GHz still disappears.

    I may just have to do a step-by-step manual config with save & reboot as @shibby20 suggests. Will have to see when I have more time to spend on it. It's not a major issue for me at the moment.

    Thanks, @shibby20 for all your hard work on the builds.

    I know i'm resurrecting a old thread here, and i apologize, but i had initially posed in the general shibby release thread http://www.linksysinfo.org/index.php?threads/tomato-shibbys-releases.33858/page-32 that i have also been experiencing this issue.

    My experience i believe between either 115 or 116 and the current 119, when i enable the bandwidth limiter the 5ghz radio does not load with the rpc_dbus_state_change: DBUS is down, bcm_rpc_tp_attach: dbus_attach failed errors. That is after saving and rebooting configuring onea at a time the following:

    1. basic and advanced settings, including port forwarding
    2. settings for USB drive support, samba and logging
    3. openvpn client config
    4. then access restriction rules

    at this point after each of the reboots, the 5ghz radio loads fine

    5. access restriction - just enable with no ips in the table and reboot (every other reboot, or intermittantly the radio wil load)

    6. fill out the access restriction table and reboot - no radio, not after 5 or 6 reboots.

    at this point i have to clear nvram and start over to get it back. I hope thats helpfull, and i'd be glad to provide additional information if needed.

    i'm having the same problem, i reset the router to the default setting and reboot it to get the 5GHz work once again, somebody has figured out a final solution for this.
    thank you

    Hi! A few months ago, I have bricked my E3200 with a firmware for E3000 (tomato-E3000USB-NVRAM60K-1.28.RT-MIPSR2-119-Big-VPN.bin). Then i have debricked after the description here , and some other forums, with the firmware (tomato-E3200USB-NVRAM60K-1.28.RT-N5x-MIPSR2-117-AIO.bin).
    After this process as a side effect i have now a fully working 5GHz wifi.

    I don't know how... I don't want to advise to do so, I'm just wondering how is it possible.

    As far as i remember, i uploaded the previous firmware through ftp, and made several nvram resets from console.

    Now I'm affraid of updateing my Firmware, I don't want to loose my 5GHz wifi again.

    You lose it after applying certain settings.

    Last I recall it had to do with using OpenVPN. However, I gave up on the 5GHz for the E3200. Even when it worked, the 5GHz would drop after doing continuous high speed streaming over it (file transfers, torrenting, etc).

    They're now sitting in storage as backup and as I use N66 and E4200's for 5GHz AP's now. Much more reliable.

    I am running Tomato Firmware 1.28.0000 MIPSR2-121 K26 USB AIO on my E3200 and loose 5Ghz radio every time I try to enter the VPN Keys by copy and pasting them from Notepad ++ using the GUI.

    I started out by entering the CA keys, saved and rebooted. 5Ghz radio OK in Basic Network.
    With the CA keys still entered, I then entered the Server Cert keys, saved and rebooted. 5 Ghz radio OK in Basic Network.
    With the CA keys and Server Cert keys still entered, I then entered the Server keys, saved and rebooted. 5 Ghz radio was gone from Basic Network.
    With the CA keys and Server Cert keys still entered, I blanked out the Server keys, saved and rebooted. 5 Ghz radio was OK again in Basic Network.
    With the CA keys and Server Cert keys still entered, I left the Server keys blank and entered the Diffe Hellman keys, saved and rebooted. 5 Ghz radio was OK in Basic Network.
    At this point I had the CA keys, Server Cert keys, and Diffe Hellman keys in and Server keys blank and 5 Ghz radio was still good in Basic Network.
    I blanked all the above keys and entered only the Server keys, saved and rebooted. 5 Ghz radio was OK in Basic Network.
    I left the Server keys in and entered the Diffe Helman keys, saved and rebooted. 5 Ghz radio was gone from Basic Network.
    One more time I blanked the Server keys, entered the CA keys, Server Cert keys, Diffe Hellman keys, saved and rebooted. 5 Ghz radio is again OK in Basic Network.

    Hope this helps in some way to figure this thing out.

    EDIT: Found the solution at this post http://www.linksysinfo.org/index.php?threads/nvram-32k-size-error-with-openvpn-use-jffs.36950/

    I used the USB Drive solution by kthaddock in Post # 2

    The path is slightly different on my E3200 and is as follows

    ca /tmp/mnt/USBDRIVE/openvpn/server1/ca.crt
    dh /tmp/mnt/USBDRIVE/openvpn/server1/dh2048.pem
    cert /tmp/mnt/USBDRIVE/openvpn/server1/server1.crt
    key /tmp/mnt/USBDRIVE/openvpn/server1/server1.key

    5Ghz radio is OK in Basic, Network again since I blanked out all keys, saved and rebooted.

    "my name", perfect workaround for this issue ... now i have TUN and TAP vpn configured and 5.4Ghz working.

    thank you

    Hi, just signed up to say..

    0) Owner of E3200 with Shibby's (great!) firmware here.
    1) Needing to get both OpenVPN (tun) server and 5Mhz working.
    2) Thanks to everybody that came with the conclusion of this be a nvram free/used issue and providing the jffs/usb alternate storage trick. It worked here!

    Testing this issue a bit more (without applying the alternate-storage solution above):

    3) I tried cleaning everything I was able in my configuration (dhcp leases, macs, ssh certificate, port forwarding examples, QoS settings... and so on.
    4) Before the cleanup, nvram dump was: "1298 entries, 36233 bytes used, 25207 bytes free." => OpenVPN server ok, but 5Mhz not working.
    5) After the cleanup, nvram dump was: "1298 entries, 34184 bytes used, 27256 bytes free." => OpenVPN server ok AND 5Mhz working.

    So, really, only a few bytes make a difference. Really weird. More when the E3200 reports it's plenty of nvram room to store everything. Maybe there is some flag somewhere not properly set for E3200 builds? Just guessing, note I've not bloody idea, at all. But it would be soooo great to have both working by default...

    Ciao :)

    May be a bit late, but after clearing OpenVPN Client -> Client1 -> Keys -> Certificate Authority (i.e. vpn_client1_ca="") and do a reboot let the 5 Ghz device appear again.
    After some further testing:
    • 1 Certificate -> ok
    • 2 Certificates -> 5G missing
    • 4 Certificates -> ok
    It is really strange.
    My config: e3200, OpenVPN Client TAP, no USB devices etc.

    I had the same 5 Ghz problem as well when using OpenVPN with the keys but was able to solve the problem by putting my OpenVPN files on a USB stick and then pointing to them under VPN, Advanced Tab, Custom Configuration.
    I did not figure this out myself. I think it was kthaddock but not sure, posted the information somewhere on the Tomato Shibby Releases Thread as I recall.

    UPDATE: Found kthaddock's fix. Second post at this link http://www.linksysinfo.org/index.php?threads/nvram-32k-size-error-with-openvpn-use-jffs.36950/

    Here is my VPN setup using kthaddock's fix.
