Internet connection needs occasional reconnects w/ Tomato 1.17

    Hello, since I installed Tomato 1.17 last week, I have observed a couple of occasions where I lost the Internet connection (the local LAN was fine as I continued to have access to the router's web interface.)

    Both times, I disconnected and reconnected through the Status/Overview page. The connection came back without the need to reboot the router.

    These occurrences could be a complete coincidence with my recent Tomato installation, but I'm wondering whether I need to set certain things for Tomato to work better with my ISP.

    I believe I have pretty much everything at default as follows:

    ISP: BellSouth (now AT&T) FastAccess 6.0
    Connection Type: PPPoE
    MTU: 1492
    Connection Mode: Keep Alive
    Check Interval: 30 seconds

    Any ideas? Thanks a lot.

    Also, after the second reconnect, I tried to look at the logs, but it seems that the logs had reinitialized after the restart. Next time I lose the connection I'll remember to check to see if there's anything suspicious in there.

    I for now have downgraded to 1.15 to see if I can maintain a better connection, as the 1.17 sticky thread contains a number posts that seem to indicate 1.15 is more stable.

    Please update your comparing result between 1.17 and 1.15 regarding PPPoE break issue. I have similar problem, but not sure is it ISP's problem or not.

    Hi @ All,

    for the last 3 months i had pppoe troubles. After a lot of testing and having contact with my ISP it turned out to be a problem with traffic inactivity. My ISP disconnects after an inactivity for more than 15 minutes. So i planned a cron job which pings the Internet every 10 minutes an all my pppoe problems are gone -> ping -c 1 -q ipadress
    I contacted Jon about this and maybe :wink: he is implemting this as an option !

    ISTR that 1.15 had an issue with leases not renewing at half-time causing the WAN to bump when the lease expired.

    That certainly sounds promising. I do think that I was using the Internet while it went down though. I used to have Thibor 15c and don't recall ever experiencing anything similar. Again, it still could be just coincidence. On the other hand, there have been many fixes for PPPoE in the recent Tomato revisions. I wonder maybe it's not stable...

    One would think that PPPoE as a protocol should be now mature and stable.... Maybe not.

    For me the "new" pppoecd is rock stable and had no relation with my troubles

    1.15 so far has not had any connection problem. Of course, the original problem occurred so infrequently with 1.17 that I won't draw any conclusion yet.

    WRT54GL (Tomato 1.17) speed of connection goes down per PPPoE protocol with connected Desktop PC and wireless laptop.
    utorrent worked in both cases.
    Situation improved after manual reboot of router (twice).

    I've seen it happen sometimes, the occasional reconnects are actually random reboots. If you check logs/uptime they start from the beginning again.

    In my case, it was not rebooting because it shows the status as connected. Everything looks fine, but there is no Internet connectivity.

    Update: I have yet to experience a reconnect with 1.15. I hope I'm not missing anything interesting between 1.15 and 1.17. When 1.18 comes out, and if it contains another PPPoE fix, maybe I'll try that one. For now, I'm sticking to 1.15.
