Questions for Tomato kernal 2.6 latest build

    I have 2 questions:

    1. After restarting any PC connected through LAN, I get this log messages:
    Code:
    Feb 19 12:10:55 Router daemon.info dnsmasq-dhcp[512]: DHCPREQUEST(br0) 192.168.1.2 00:1f:c6:62:6c:97

    As it wasn't the case with the previous release, I just want to know if it's normal or not.

    2. Does anyone else use PPPoE to connect to ISP? I get random disconnections from time to time, and it hasn't been the case with the previous version. I hardly doubt it's an ISP side problem, usually I get 6-7 days uptime for the WAN connection...

    Code:

    ..........

    I don't understand the first line, why is the router "Sending LCP Termination-Request" ? The connection mode is set up as "keep alive", heck interval is 30 sec, and it was the same with beta2 version, which did not have this problem.

    So, anyone having the same problems?

    Thanks.

    Catalin,

    1. This is normal, and is the default dnsmasq logging behavior as in vanilla Tomato. In my previous builds I disabled it because my wireless clients were flooding the log with messages every minute or so, but apparently some people need it, and I received several requests to put it back.
    If you like the old, quiet way better, you can disable this logging by adding a new "quiet-dhcp" option to the "Dnsmasq Custom Configuration" box on the "Advanced - DHCP/DNS" page.

    2. Do these reconnects cause you any problems? If they are not initiated by your ISP, I believe I might know what caused the change in the behavior. In the last build I applied the recent patch from Linksys GPL code claiming to fix a problem when the router doesn't see the disconnect from ISP, and only attempts to reconnect 240 seconds later causing the 4 minute service interruption. The patch changed it to reconnect immediately after receiving PADT from server.
    If this causes a worse issue than it solves, and if this is indeed the new patch that is responsible for that, I'll remove the patch. Let me know - I may need you to run a few tests to confirm whether this patch is the cause or not.

    Thanks for reply.

    I did another test: I've reverted to beta2 firmware, and it's working fine, no more disconnects... So now I'm 99% sure it's got something to do with the new firmware. I do not think they are caused by my ISP because it is usually a very fast and stable connection (100Mbps bandwidth), and it would be a very big coincidence, since it started happening fust after I've updated the firmware.
    Well, it is annoying in online games and stuff, because the server or host connection is lost, even if the router reconnects in a few seconds... If you could help with that, thanks in advance.

    Later edit: Problem solved by using a modified beta5 firmware, not containing that Linksys GPL PPPoE fix. Big thanks to TB. :)

    I am running teddy_bear's beta5 on a RT-N16. I use ppoe for the Internet connection. I am not having any disconnect issues. Thruput is good both between devices on the local net as well as to the Internet. So far I do not have any issues with the beta5 build, but I am not doing anything with usb at this time. Will in the future which is one reason for this purchase. Old router was a WRT54GL running VecteK mod. Probably the best for normal use.
    Just one thought. I do a nvram reset when I do any upgrades and reinput my settings. Know some folks claim you don't need to when just going to a newer build. But I do not seem to have the issues other folks have.

    There's the thing: I have some feedback from other users that had the same problems with the original beta5 firmware version. After flashing the patched beta5 version (the one from which TB removed that Linksys GPL code) everything works as it should, no more disconnects.
    I don't know, maybe it's related to different PPPoE ISP configurations, but that was for sure the cause of my and other's disconnect problems, and it is 100% solved now.

    Yes I confirm that, no more random disconnects.
