Jauh gak tu....1st of all, cari wireless router yg boleh manage that distance.Kalau tak boleh, kena le cari tempat in between & letak AP (Access Point) so boleh link the 2.Or like you said, U can get uni-directional antenna, tapi mahal le sikit.

Sorry, dah lama tak check on this....Smtg like, I was out-of-commission for a while, but I can dig up smtg...

Then, kau kena consider security issue; lock your network with WEP & setup a dedicated firewall; Windows punya tak aci....Kalau ada computer lama, maybe you will be interested in www.ipcop.org; very easy to setup yet will give you a good & reliable firewall.Banyak gak nak consider ni...Kalau tak, happy le org lain; tapi kau yg merana nanti....

Later...

ko pakai pc ke laptop?

kalau pakai pc kene la beli wireless dongle cucuk kat pc...

kalau pakai laptop bende tue dah built in.. (laptop sekarang)

ko connect jer la
detect wireless connection dan connect ajer kepada kawan ko punye connection..
tapi takut jarak router kawan ko tue tak jauh..

Heh...Sorry, tak nampak lak "dari rumah kawan kau" tu...:loveliness:Aku ingat rumah kau yg nak jadik host, cuz kau tak cakap PC ke laptop...

Anyway, like stingbeh said... get the hardware on your side first, or borrow someone's laptop to test.Camne housing area tu?Takut signal dia teruk sangat nanti.Kalau takde menda besar yg block, on the way etc...

The rest, just ask him the details: SSID & the key to his WiFI connection; make the connection & off you go.WinXP shouldn't be a problem, Vista maybe degil sikit.Oh yeah, built-in Intel chipsets datang dgn most laptop might be a bit cranky to setup...

aku dah cek kebanyakan MIMO router especially belkin buleh jadi repeater a.k.a. wireless bridge.

maknanya kalu signal tu tak sampai kerumah, maka dalam jarak 120m tu, kat tengah2 tu kena cari memana jiran yg sanggup bagi tumpang ko letak MIMO router ni. so, signal dari rumah kawan tu akan di repeat dan dipanjangkan sampai la ke rumah ko.

ni screenshot belkin souter setting.

tapi kalo nk guna as AP (Access Point) pun buleh gak.

MIMO ni mahal lagi le bzzts; last time aku check le...:D   AP lagi murah, plus most of good router can be an AP.Check je lah masa nak beli tu.But, kalau ada MIMO lagi bagus; cuz that's a definitive technology specifically designed to boost signal strength...

BTW, check on the neighbor that you wanted to leave the Wireless MIMO AP also...:lol:   Jangan dia berkenan & cabut dgn Router tu dah le...hahhah

AP paling murah aku jumpa pun RM550 ++

mimo ni paling murah pun RM300++ je.
belkin aku ni pun beli seken RM100 je... ;P



**MIMO = Multiple In Multiple Out.

ok...

camni situation

rumah kawan aku jadi host la...on his side dah ok bab2 firewall nih.... dia pakai Dlink wireless router/modem...

aku pakai laptop je ni... memang umah aku tak dapat signal umah dia.... memang dia ade set WEP key dan macam2 lagi.....

masalah skang aku nak kasi laptop aku detect signal umah member aku ni

FYI, umah aku dengan umah dia jarak dalam 150m (maybe less), kalau ikut air distance la..
kedudukan pon betul2 lurus selang 3 blok umah je...
kalau ikut takde halangan besar ke rumah dia yg ade bumbung2 umah... pokok2 pon takde yg tinggi lebih bumbung umah...

ade solution yg murah2 ke??

kalau ikut Bzzts cakap nak install AP ni payah la sikit sebab melibatkan electricity cost org lain n tak satu pon jiran dalam in between tu aku kamcing..... so payah la sikit

aku pernah terbaca kena install wireless anthena ke, ade org suggest aku kena pasang wireless router gak kat umah aku..

ade solution lain tak yg melibatkan bajet bawah rm500... tak kire la brape banyak hardware aku kena beli??

Kat mana kau beli Belkin?Nak cari ADSL Modem ni, penat aku carik; semua datang dgn router, no straight modem.Cuz I have a homemade Linux firewall, so factor in firewall settings kat dalam router mau complicated nanti...Anyway, boleh disable but I don't like paying extra for smtg that I'd never use...:D

BTW, Belkin is a good brand & have an excellent reputation in the US; kat M'sia takde org kenal kot...I saw Belkin UPS selling dirt-cheap; with & without the packaging....

Anyway, for ppl who cares:
MIMO, MISO and SIMO

Following are the advantages of using multiple antennas rather than one. The terminology is "M" for multiple, "S" for single, "I" for input and "O" for output; however, the inputs and outputs relate to the air, not the device. This is a peculiar notation; nevertheless, multiple inputs (MI) means multiple transmitters are sending multiple data streams "into" the air. Multiple outputs (MO) means multiple receivers are receiving multiple data streams "out of" the air. See 802.11n, antenna diversity and HSDPA.

ARCHITECTURE AND ADVANTAGES OF MULTIPLE ANTENNA TECHNOLOGIES
                           Compared to Single Antenna Technologies
                           
               Transmit               Receive                              Data
Type          Antennas             Antennas                           Rate               Distance
-------------------------------------------------------------------------------------------------------------------------------
MIMO         Multiple               Multiple                           Greater             Greater range

MISO         Multiple                  Single                              Same            Same range but
                                                                                                             More Reliable

SIMO             Single                  Multiple                            Same               Greater range

takde jiran yg ko kamceng? cemana pulak dgn kawan ko puya jiran?
ala, offer je kat org tengah tu, kalu kasi tumpang router; dpt internet wifi free :lol:
duit letrik kalu router tu on 24jam sehari pun rasanya err... RM10 dah memadai kot.

takpun cuba cek jiran2 sbelah kot2 diorg ada streamyx, offer je wifi router kat umah diorg terus.
janji ko dpt signal, pakai free. atau bayar RM20 sbulan pun dah kira murah.

jiran aku dok kat proton city perak, pakai wifi router, share 4 rumah, 6 client (pc & leptop).
100meter radius. blok sbelah2 je. collect RM40 sorang, darab 6, lepas la monthly bill streamyx dan telipon dia.

I must be getting old....:lol:


Anyway, electricity tu tak banyak mana sangat pun...just complicated sikit kau nak letak kat tempat yg kau takleh access...Kalau AP tu down, kau nak kena call the guy; nak kena pegi tengok or paksa the guy tengokkan AP tu; reset back or smtg.Payah tu....Kalau takleh dapat signal tu susah le sikit, kena suruh kawan U pasang booster antenna le...

Kalau nak try, pinjam je router/AP sesapa jap & try boleh tak dapat signal dari rumah kau.Maybe, you got lucky & coverage radius dia everlap....

oh ye, pointer tu, ko kena cucuk kat wifi adapter. pci atau USB wifi yg ada antenna.
pendek kata leptop punya built in tu takyah guna.

ni contoh USB wifi yg aku maksudkan tu, ada antenna, so buleh cucuk wayar cantenna tu ke situ.
