No4, use long LAN Cable to PC, or my better recommendation, use another Router , LAN out from Router 1 which is near Antenna ( use a long CAT6e cable to LAN out into the WAN of a pure Router ( MikroTik ) in the middle of the house where the Ipad/Iphone are located. Then you can LAN out from MikroTik into PC room via LAN if WiFi in PC room is not strong. But MikroTik should be very strong enough as it can be detected 6 floors without external antenna.

If no 4,  better use homeplug. Eazy installation but need sone fund. Btw, homeplug work on single phase.

Router still can use. Only dont know how to use command for router to download the proto3g package. If use ubuntu easy to download and install package...

Flash back to stock firmware.

I using homeplug, no ping and speed difference compared to LAN.

You can use any router for extender. No need bought router with modem.
Should be cheaper... But for extender, better buy with many LAN port, not just one.

This is similar to option No 4 

Second router use MikroTik is the best option.

No need to be 2 MR3420

1 MR3420 for the 3G router

Another one just any Wireless Access Point or Any Wireless Router will do

Or you can buy a wireless extender homeplug but a router will do the job better for sure

Nope.. 1 MR3420 is enuff. Another Router is just Normal Router (without for 3G or ADSL)
Unless Normal Router for your Network Extender more expensive than MR3420...

just get mine 3420v2 today....
searching high/low at plaza lowyat for the good deal...finally

Bro, you climbed on top of your roof to test it with your Antenna + Laptop ?



   

Th antenna gave me very good Upload speed, but not Download speed

1st, you must have Hand Drill.
U can use bracket that hold the "Analog" TV antena and shaft. Buy a cable ties also. Steel band need to make bracket is necessary. If the cable not long enough,need to put the router near the ceiling. Just make a new Hole to hook up to router.

You need to source "Low Resistant" cable. Its no cheap i think. Not sure where can get.
Cheap cable have high resistant and can cause the speed drop.

Or need to put your router near the antena or "Loteng" (Not sure English work Attic?), but another router to extend the network.
For us that have very difficult to facing the antenna to the tower, sure need to "invest"
some fund to get better result..

The important is stability, even the signal around 20-50%, and u can get download speed 800KB-1MB (By using IDM) should be puas hati kot...

I think Aztech is currently the best brand available

I having both aztech and TP LINK

The 115EP 500mbps model is nice

blacktubi,
aztech what model?

i now dealing with ppl getting TL3420 after that i going to flash to openwrt 

If you want Homeplug + Wifi + 2 Port Lan,  Bought This (1 is Enough)
http://www.lelong.com.my/aztech-single-wif...7-01-Sale-I.htm

So, use this connect with other homeplug that connect with your router.

Huh what do you mean by connect cable to the modem?

Surround the antenna cable a few times on your modem
