so the speedtest detects single channel speed only

You can never apply heatsink at MF680

The case antenna stop you from doing so

Hardware Modification

Add Heatsink to your modem

E367 > MF680 > MF820D

Regarding on where to get those heatsink, please look on Garage Sales section.

umm . . .
Isn't this MF680 ?

Nope

The left one is MF820

The right one is E367

MF680 just for a size compare purposes

nope.. mobile partner is the one that falsely tell the speed.. have it for my E372 too.. to test real speed, i never use the speedtest but idm with microsoft files..

yeah, the most accurate way is using IDM download speed

DARN!!

So, which one the most stable at mid range speeds ?

Huawei E372

Exceed budget a bit

Better save yourself than using RM 200 on a cheaper smartphone.
No offence but this is how I feel.

go for e398 to get ready for LTE..

E392 is like the test baby for Huawei

It just like ZTE MF820 the first ZTE LTE modem.

E392 is big hot and unstable just like MF820

I am a noob here 
so, what's LTE ? 

its ok mate..LTE stands for LONG TERM EVOLUTION..more info about it can be see from link below..

SOURCE

The time when 4G will hit MAsia I might be thousands of miles away. So, going for the 3g

MAXIS will launch LTE on early 2013..better get ready for it coz at that time all LTE modem sure kena sapu..

idk, i aiming nexus 7 actually, if got. i terus sapu liao. but so far telco no bring nexus7 with data plan. 

why don't buy it seperately? Nexus 7 32GB costs like RM820 if buy from Newegg Malaysia. I doubt if telco bundle plan will give that cheap price.

Modem Recommendation Table

Speed :

E367 < E372 < 320U <  ( MF680 = E398 / MF680 < E398 )

Stability :

MF680 < 320U < ( E398 = E372 / E398 < E372 )

Price :

MF680 < 320U < E372 < E398

Verdict :

Sierra Wireless 320U : Most affordable LTE Modem. Some stability issue but not as serious as MF680.
ZTE MF680 : Speed almost on par with Huawei E398, need to cool it properly else it is a pain on stability.
Huawei E372 : The most stable modem you can get. Easily modified. Speed is not amazing for E372.
Huawei E398 : The balance blend of stability and speed, completely future proof for now.

Maybe you can add iPhone 5 to compare.
I feel iphone 5 speed more stable than my sierra modem and no hot.
but price very expensive. I use iphone 5 speed can up to near 30mb.
