Flash to the latest firmware and dashboard. i'll find a way to cool it...  Added on October 17, 2012, 9:53 pmAnyway, OpenWRT is good, except of the 3G support is a bit choppy. If your 3G dropped, a full power cycle is required to reconnect. This post has been edited by blacktubi: Oct 17 2012, 09:53 PM |

QUOTE(Ruzumaki @ Oct 17 2012, 07:27 PM) My MR3420 cannot survive with TP-link official firmware. Just set a cron job for the router to ping something every minute so that the connection wil not become idle.Official firmware throttle my speed to 0.1~0.01mbps speed So I did some research and found the tutorial to flash openwrt on this website. I find it very Newbie Friendly, so I decided to share the link here. http://www.kaskus.co.id/showthread.php?t=10124215 Don't forget to remove the %2A when download the openwrt firmware http://www.4%2Ashared.com/file/LqtTaVCL/openwrt-mr3420-v1-squashfs-fac.html Flashing openwrt require patient and time, configure can be tough for newbie. I manage to install miniupnp and setup DNS myself by googling for 1 days. I brick once my MR3420 once for wrong DNS configuration, but I manage to save back my router due to the very powerful failover function. Openwrt is damn fast and powerful, allow 3G modem to successfully dial connection within 10sec. Damn love openwrt now, my speed damn so consistent all the time 10mbps++ Now I facing a problem is that my 3G modem will dc after idle sometime (few hour), it always dc when there is very less Active IP Connections. (DC when I didn't open any download) I always face dc problem when I put the connection to be on and idle overnight. Although I have set my auto-disconnect value to 0 or a very large value, the DC problem still occur when there is very less Active IP Connections and it idle for long time. The auto-reconnect function in Openwrt is not working as what I expected I saw something like this in my log, I notice there is auto-reconnect mechanism running but it is not successful. I click restart connection button on openwrt network interface webconfig page but it still fail to connect. I found that I have to manually restart the network interface (WAN) so that it only can successfuly reconnect. I use ifdown wan0 ifup wan0 in SSH to let it restart the network interface. Anyone have idea/script how to solve this? Logs » Click to show Spoiler - click again to hide... « It's under System > Scheduled Task. Example command: * * * * * /bin/ping -q -s 1 -c 60 8.8.8.8 & > /dev/null That command will ping Google DNS 60 times every minute. |

Added on October 18, 2012, 5:40 amspeed this hour on tp link stock firmware is good, so i think after all no matter whether tp link stock firmware or open wrt firmware, still depends on maxis,. the Open WRT firmware can't Reconnect after DC as i try just now,. so is When I first use OpenWRT, I use image from trunk. Trunk doesn't have web interface & I installed it manually (my choice is LuCI) but trunk currently down ( I don't know since when: http://downloads.openwrt.org/snapshots/trunk/ar71xx/ ). It worked quite good & auto-reconnect after dc. Then I tried image from stable branch (named "Backfire": http://downloads.openwrt.org/backfire/10.03.1/ar71xx/ ) but it have a couple of bugs including failed to auto-reconnect after dc & some other bug I don't remember (these bugs probably got fixed or not with later/latest release). Now I'm using beta branch named "Attitude Adjustment" ( http://downloads.openwrt.org/attitude_adju...ar71xx/generic/ ) & works great. The auto-reconnect take around 20 seconds after dc. For trunk image, I did explain how to flash & configure (install web interface, 3g, etc) over here:- http://forum.lowyat.net/index.php?showtopi...post&p=49464934 At the moment I recommend image from "Attitude Adjustment" branch. It have LuCI web interface by default.
I have seen a 3G modem, can't remember which brand, got "fat" because of heat but my Sony Ericcson K660i phone works just fine without any fan cooling it & it running 24/7 since 4 years maybe. My MR3420 will be one year old this 30 October & also doesn't have fan cooling it either. Works well so far & doesn't hang even if I accidentally bumped it (I did knocked it with my fist because my phone suddenly off while playing BF3 ). Also wireless N connection works ok for me, connected at 300 Mbps, no drop of connection at all & the coverage quiet good.This post has been edited by kizwan: Oct 18 2012, 09:25 PM |
