ADSL2MUE http/snmp issues

    I am wondering if anybody can help I have a Linksys ADSL2MUE modem with Linksys 4.22EU firmware installed and I am having a problem with the http access and the snmp output locking up for want of a better word. I use a copy of "The Dude" to monitor my network and every 4 or 5 hours the http access fails this is reported by Dude and from a browser I just get timeouts, at the same time the snmp stats also stop. If I reboot the modem everything comes up no problem at all for another 4 to 5 hours then it happens again. While the http/snmp is down web traffic still work fine, the modem can be pinged ok and SSH access appears unaffected. I have reinstall the 4.22EU firmware, reset the system but nothing seems to resolve the issue. The modem is used in bridge mode for my WRT54GL which uses tomato firmware. The only error I am seeing in the log file is about "manager not found inode" which repeats about every 2 to 5 minutes, I have searced the web for this but can't find what this means or if it is connected to these problems that I am getting.
    Does anybody have the same or similar issue?
    Does anybody know how to fix the issue?
    Alternatively is there any other versions of the Linksys firmware or an alternative 3rd party firmware that will allow the modem to be used in bridge mode but is more stable?

    Thanks in advance for any help given......

    The answer is yes and yes, but I have no idea whether they will fix your problems as I don't yet use snmp.

    The 2MUE is based on an all-embracing 1-chip TI AR7 platform which is common to many ADSL modem/ routers. This uses Linux with proprietary extensions which has held back 3rd party firmware (IMHO) as Linksys, for example, have never published fully compilable source code. 3rd party firmware has to be pieced together from a variety of sources. Hopefully CISCO will soon see sense and publish their source code so it can get the care and attention it deserves to become an ideal companion to WRT54GL.

    There is an Australian version of the firmware 2.17 or 2.18 around that has more config screens available, but the ADSL drivers etc are probably now obsolete (A lot has happened in implementation of ADSL2+ in the last couple of years).

    I have reported on here that Routertech firmware does work on the ADSL2MUE (if you ignore the incorrect coloured LEDs), and following a tip from a super developer here you can then load some DLINK firmware to make the ADSL2MUE work in PPPOA half-bridge mode (with even worse LED behaviour).

    If you search you will also see that I needed to swap the Linksys supplied 5V/1A power supply with a 5V/2A (from NSLU2) to get my ADSL2MUE to hold sync in ADSL2+, and I have another ADSL2MUE with a suspected failed internal 3.3V regulator (may only be rated for 0.8 A!). Does yours work well with basic ADSL function?

    I also remember getting an "manager_get_defaults - !node" message with the Linksys firmware, not sure what it means but it makes the logfile useless, but is not specific to Linksys so probably a TI software problem!

    mstombs - thank you for your help, I have updated the router with the latest Routertech firmware (v2.1) and it's brilliant, I only use adsl2 not 2+ and I am not have any sync problems, everything (expect LED's) is working for me....

    For anybody else with this modem (ADSL2MUE).... try this firmware it is excellent, stable and compared to the Linksys standard firmware it turns this modem in to a completely different machine.... The only issues I have seen is the LED's, the internet activity LED does not work and the Power light is red not green which normally shows an error but there's no error on the box, this issue appears to be linked to the LED config file in the firmware not be for the asdl2mue.... As per the above post is you use ADSL2+ there may be some sync/power issues but I don't use 2+ so don't have this issue.

    Hi paped, sorry about the snmp - sure I saw it in the web interface or documentation! One good thing about the RT firmware is that it is not fussy about what firmware you load next (dangerous, but useful!) I wonder if there is a compatible Russion Acrop version with the functionality you are after

    I have posted a partial fix to the led.conf over at rt. I suspect you could recover the filesystem, unsquash it, change led.conf, resquash it, fix checksum then reload but that is currently beyond me.

    Note RT continue the manufacturers trend in not releasing fully buildable source to recreate binary identical firmware, so you must wait for them to provide full support for the ADSL2MUE (including LEDs and half-bridge) - but they seem to be taking more interest the more people ask!

    Its also interesting to note that the RT firmware runs on modems with 2Mb flash 6Mb ram, the ADSL2MUE has 4Mb flash and 16Mb ram so still has plenty of potential!
