another Flashoholic onboard..........

 

I take back my words about not having any issues with Huntsman firmware. I did a few more tests yesterday and found out that if I'm using "Enabled with Restart" for Connection Keep Alive under Modem > Connection tab, the connection won't be kept alive if it's idle for too long. I'm not sure if it's telco specific but for Maxis, it's almost consistent. The only way to get back the connection is to either reboot the router or take out the modem and plug it back in.

Perhaps Dairyman or Wahroonga Farm can check it out.

All this while, I've been using "Enabled" without the restart because I have my own scheduled tasks to monitor the connection and restart if necessary. That's why I don't have much issue if the connection got stuck.

that command is to keep the connection alive by pinging Google DNS every minute but doesn't do anything else.

I'm using this:
*/5 * * * * /bin/ping -c 10 openwrt.org || reboot

It will ping openwrt.org every 5 minutes with 10 tries and will run the reboot command if one or more out of the 10 pings failed. You can change the schedule to a shorter or longer time depending on your preference.

I can't guarantee that it will fix the issue though 'cause we'll need more time to test it out. However, at least the logic of it make sense.

hope Dairyman can enhance Huntsman somemore

Now both my MR3420 V1 and 1043ND running on Huntsman 2013-04-14. My Asus RT N-16 is left out in the cold already 

Stability 90% cause sometimes although connected, i get no internet activity ~ i believe is due to Maxis , even when i use usb modem direct plug-in laptop also like that. Not router FW's problem. Just need to wait a while, it will be back to normal without reset or turning off the power..............and IP changed after that.............

here's my load average running on Huntsman 04-19 with MR3420 V1, loading the page from my office via Public IP:
[attachmentid=3407421]

I've been running this version happily ever since I found the manual fix for cron. I'll have to stick with this version as I still need the DDNS package. 

this is how the new huntsman,.. 

my huawei E1820 not recognize at all

[attachmentid=3408216]
