just want to share a simple recovery method for OpenWRT via Scheduled Task in a scenario where the 3G connection somehow couldn't reconnect. It won't work with 3G modem using additional power source other than the router itself as we need a cold reboot for the 3G modem:
0 * * * * /bin/ping -c 10 58.71.132.10 || reboot
This scheduled task will run every hour to ping Maxis DNS for 10 times, it will reboot the router only if all 10 pings failed. you can change the frequency of when you want to trigger the task or the number of pings or even change the IP address to check.
I find this is the simplest method to use compared to using a watchdog. If you have other methods, please do share how/what you do to recover your 3G connections with this router.
I need an automated way to recover the connection because I have an IP Camera configured to keep an eye to a remote place where I only go when I really need to.

QUOTE(azim61 @ Nov 2 2012, 10:28 AM) i think maybe it is the router capability it can go only up to 21dBm i think if i select the country Malaysia, the option for transmit power can go only up to 20dBm for US, the option can go up to 27dBm but in reality, it change from 20dBm to 21dBm hmm you're right. here's a list of maximum transmit power for the TP-Link routers that I have: 1. WR1043ND - 23dBm 2. MR3420 - 21dBm 3. MR3020 - 18dBm |

Can easily do load balancing and failover without additional hardware.  what's the expected price? |

QUOTE(blacktubi @ Nov 8 2012, 02:57 PM) I actually don't feel it too but the USB cannot drive my modem properly, easily D/C compared to MR3420 or PC P/S mine is 1043ND V1.8 I'll check what version is mine tonight. Have you tested it with the USB Y-cable to supply more power to the modem like Chuah was using last time? If it's the same, it might not be power issue already.  Sell it cheap cheap to me if you intend to let go.  This post has been edited by maxcheam: Nov 8 2012, 03:23 PM |

QUOTE(fruitie @ Nov 13 2012, 04:21 AM) By the way, how to do disconnect my connection and reconnect it again without rebooting the whole router?  from Chuah's instructions until the Network step, just click this Connect button on the WAN interface and it will disconnect and reconnect automatically.  |
