yes it is 140309 version.
i put
-11bgn mix
-Channel Width as auto
-channel as auto
will it help if i set it to 40mhz?

Does any 1 setup mr3420 v2 with unifi?
I had many question and issue with it. The tutorial from kleek is v1, port is actually no same , the wan port is no detected in the openwrt...



I have same issue with u, then i just connect without modem right now..
Even the modem is same direction & position the speed is definitely different. So i think is power issue ...1800 band i had stable speed with router or direct pc, 2600 band had slowest speed than 1800 ,but if i plug direct to computer will definitely faster speed ...
So i give out alrd for the router...maybe change the power adapter to 2A will boost the speed? or the usb port from the mr3420 need more power.

Any 1 know how to setting the mr3420 v2 to unifi please let me know

if channel width is on Auto always 20MHz only,

try it on 40MHz and see whether problems still there

unfortunately it still the same.
but thanks for the reply

u can try to flash Rooter > http://www.ofmodemsandmen.com/downloads.html

on funnelweb or huntsmand,..

see whether problems still persist

If you want a good router, get the Asus one.

MR3420 especially the later batch having ton of issue thanks to TP-LINK cut cost using bad component
It doesn't matter which power adapter you use, the issue is with the 5V regulator.

Some can't even power up E3276

ok thx, so no other method to solve the issue?

claim warranty

Good luck claim warranty, hopefully they give you V1 or older hardware version.

keep claim warranty if it failed again lor,.
