Hi guys,
Just now updated to 20131110red version and my modem is connected but no idea why all my devices cant connected to the internet.

Actually this problem is already occurred on the 20131016red version too, then I just flash back to 20131012yellow and everything is working fine. I was wondering why the red version doesn't work for me.

I also tried 20131110yellow but my modem won't connect at all and i read the known issue at the ofmodemsandmen website it stated the current yellow version doesn't have USB power control.

20131012yellow > 20131110red (no internet) > stock tp-link > 20131110red (no internet also) > flashed back to 20131012yellow

My sepc: 3420 v2 + sierra 320u

Anyone could help me out?

Thanks in advance and regards.

why not u just stay with the 20131012yellow version since it worked well for your router + modem combo,..

USB power control is either ON or OFF,.. nothing special function to it,. i am using the 2013-11-10 red version now

so, i already reinstall and reset all firmware that i have including openwrt and stock for several times. 1 thing i notice is. in openwrt. everytime i plug-in my modem, it will detect my e398, but after few second, this thing will popup and it cannot detect my e398 anymore



even if i pick one on the option, and restart. my router still cannot detect my modem at all until i reset to factory. and back to step 1.

any through about this? i thinking on downgrading my modem firmware after this since i suspected that might the main culprit

what do you think blacktubi ?

syahpian

Since you mentioned it happened after you updated to the latest E398 firmware, how about downgrade it.

Have you tried the yellow build? It always work good for me
Huntsman 2013-11-10
Latest Release

i already try

openwrt-mr3420-v2-HM2013-10-16red
openwrt-mr3420-v2-HM2013-10-16yellow
openwrt-mr3420-v2-HM2013-11-10red
openwrt-mr3420-v2-HM2013-11-10yellow

all have same symptom.

and just to note that openwrt-mr3420-v2-HM2013-11-10yellow have this bug

TP-Link MR3420v2 does not have USB power control on Yellow version.

its on the website

also, upon downgrading, it asking for password, is this normal?



i`m using E398_Update_11.433.57.00.260.B757.exe

You need a flash code, give me your IMEI I generate for you or you can use any internet generator

do i need to sent it by pm?

yes

done

I'm using Huntsman 2013-06-03 with my Vodafone K5005(E398) having no problem for long hours... very stable connection.

my main suspect is the new modem firmware. that why i want to try downgrading it and see if the problem still there after that

so have you try older version rooter instead ?

Looks like the latest Rooter causing problem

My E398 on 11.433.57 works like a charm on 10-12

Dont upgrade guys

Older version works well for my e398-u15.
But currently using u1v2.

i am planning to buy this router, but wondering does stock unit can read Huawei E3276 modem? i tried with my TL-MR3020, the device does not want to read the HuaWei E3276, keep looping at "Identifying"

So thinking if I buy this MR3420, will it work with it on stock firmware?

im using rooter with e3276

so far so good, only dont mess with the setting

gastacopz, meaning once i buy i should flash the firmware to rooter and its done rite?
