got for 3420...wifi signal is better

Because of 2 antennas ?

yes. better coverage ...MIMO.

please think carefully because it has the risk of bricking your device if you are not careful

hi

wanna ask you guys opinion.

i'm already planning to buy Tl-MR3420 + some cooling fan.

Yet, I also wanna buy an Wifi Signal Amplifier to amplify MR3420's signal up to 1KM radius. Since install it will bring me more hassle, I thought to give this (Wifi Amplifier) a go. The one i'm gonna purchase is JJCorp brand, so I thought want to ask some opinion, whether is there anybody have doing the same.

Thanks.

1KM radius. Cater about 10-30 people, high stressed condition (all massdownloading/youtube/etc)

Here is the link:

JJ24BTB

or something like this.

i planned so that about at max 10 PCs/laptops. Another maybe 20-30 smartphones.

Bandwidth and quota is never a problem.

But I now still not very sure how well wifi signal amplifier works. If its only can expand through at max 100m, I don't mind as long the signal is strong enough to penetrate building. I have 5 buildings, 3 storey each, side by side, and I want to put this at the highest position,  (3rd storey). The signal must penetrate all rooms in all buildings listed. Since I thought 1KM is VERY strong signal, so definitely it can penetrate these building.

Wireless repeaters is quite a cost for me, plus there will be technical problems if I want to install it in many locations due to different ownership of those houses.

can, I tried it with a 5meter USB2.0 cable and a 3meter USB3.0 cable before

try to buy USB3.0 cable as it provide more electric current and faster data transfer....

with the USB3.0 cable, i can connect it directly to my mr3420 to get better reception on my E372...

port?wat port bro?usb port?

Back to 1043ND + OpenWRT
Found out MR3420 not stable enough for high load

I've done some *unscientific* tests a while back and found that heat does affect performance. 

I used to place the modem horizontally (as per default) and it gets very hot. Now I place it vertically and the heat was significantly reduced which lead to getting about 1mbps higher than usual 

Ver1 old design, u can search from net. Its also just support for 3G/3.7G....but ver2 is new design and its support 3G/4G... firmware also have added a little function...can see at TP Link website

Yeah, that was my old avatar and he happily used it while I was still using it. I created the avatar myself.
The signature he is using now was also created by me.

i guess even is different brand as long as it is same model, the bin file should work right? 

Even International Shipping only takes 5 Days to my door step.
