just wanted to share some of my experiments,..
i did try to use cable Y ( 2 male into 1 female usb cable) + 10 meter usb extension + usb hub with power adapter ( 1500mAh ) + Option Icon 505 / Huawei E1762 + Strainer wrapped with aliminium foil or windsurfer .... can + yagi 3G antenna as well if using CRC9 converter connector
Result is quite good, as it can really stable the connection , and speed also become more consistent,.
i try this on the 2100MHz weaker signal indoor my area,.. and for celcom skmm, this combination will get u 1.5~1.7Mbps 90% consistency speed,...
for people who wanted stable connection due to the signal is weak, even after try most thing,. if u using Huawei modem, try this MDMA Beta 10
. can download it here : http://nerve.org.za/mdma/mdma10031beta10.zip
use the MDMA Beta 10 with that combination above, find a best spot then setup whole combination, higher powerful modem always need more power to performs,.
example something like photo below,:
Cable Y ( 2 male into 1 female usb )
USB HUB with external power adpater ( mine is 1500mAh )
Windsurfer ( can download it here http://www.freeantennas.com/projects/template2/
works for all wireless device in concentrate the signal
Yagi 3G external antenna + CRC9 converter connector
Strainer wrapped with Aluminium Foil
Combination is something like that,..
and also remember make sure
- your USB modem firmware and Dashboard is the latest up to date,.. ( can refer dc-files.com
, there have most model of usb modem )
- plug in the modem into usb port 2.0 or 3.0 instead of usb port 1.1 ( can check under device manager )
- make sure your window usb port driver & modem drivers is up to date ( personal suggestion can try slim drivers
software, it is free and very efficent to update ur driver )
- move ur usb modem around in your house/area to find the best spot for it,. refering to MDMA software,.. base on the RSSI & signal strength bar meter,.. and u can tweak 2100 or 900MHz 3G band only so ur modem dont have to work so hard to scan all band that available then concentrate into signal band u choose,..
This is all my Experience & experiments .. just to share with anyone who have signal problems, wanted a stable consistent wireless bradband connection ,
if u have any disagreement to my point of view, please kindly post your experience or experiment to support your Theory,.
i can;t guarantee this method will work 100% for you , but i am sure it confirm works for u,..
and lastly , if u wanted to try, try it on your own risk too,.
p/s:windsurfer & strainer as antenna is credited to original founder,...

For those who is looking for stable steady consistent speed and yet staying in area signal weak,
i suggest u try the ZTE MF600 modem,.. as the external antenna really power up the 2100MHz 3G band signal,,..
or u can try huawei B660 ( Huawei 3G Router - B660 Wireless Gateway with Integrated 3G Modem )
or this Bigppond
( 7.2 Wireless Broadband Home Network Gateway Router)
for who staying at signal very poor area,
ZTE MF600 will really suit ur need as the external antenna that come with the modem itself really power up the signal,
as normally i get RSSI:- 77 ~ -85dBm, after using this modem my RSSI : - 59 ~ -68dBm
of course this modem is support 3.6Mbps download speed and 384Kbps upload speed,
as my theory is because of Power supply + external antenna, then that's why u can get higher signal + stable connection + consistent speed,..This post has been edited by chuahcs79: Jan 27 2012, 12:09 AM
