Just purchased TP-Link TL-MR3420 at PC-Expo, Mid Valley.
Thinking to get Huawei E367 for myself.
Noticed that there are 2 types available, E367-U2 and E367-U8, may I know what the difference?
Thx in advance

E367u-8 stock version, whereby u-8 is quad 3g band: 850MHz+900MHz+1900MHz+2100MHz, the complete bands worldwide applicable verison! that's y stock run faster.

( Additional Info:
If u not aware, each Huawei 3 series modem model are divided into several stock version, denoted by the last digit number of the model number. E.g. E353u-1, E353u-2...  E367u-1, E367u-2, E367u-6, E367u-8....  E372u-1, E372u-2... etc. see the u-1, u-2 difference?

The difference is which 3G band and how many 3G band supported by each modem version.
u-1 generally refers to support single 3G band: 2100MHz only,
u-2 refers to dual 3G band: 900MHz + 2100MHz ...
(if u have been duped u-1 is multiband ... good luck ...  )

How to check:
a) online database resources such as: http://3g-modem.wetpaint.com/page/USB+modems
b) use Huawei Mobile Partner software: Tools > Options > Network: All band (just like in the above picture).

Yea, luckily it is work now. It not really troublesome.
I do check the setting one by one but everything seems same~
Maybe the system problem not broadcast the ssid but still showing yes. 

By the way I tested umobile speed not bad. Very fast~ but still not sure stable or not.
wish it is stable~ 

my umobile mf190 unlocked since day 1 I bought...  you can try upgrade firmware from the website.
