sa win notebooka sa wifi karticom:

  ssh root@192.168.45.1

expander se zakači kao interface wds0.49154

root@router:~# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.0013104388bf       no              vlan0
                                                        eth1
                                                        wds0.49154

međutim, problem je što su ostali njegovi stari parametri 192.168.1.x tako da se ne mogu zakačiti na njega

hm da li ova expander obavlja svoju funkciju - on se uspijeva zakačiti za router ... pa možda i nije potrebno podešavati ip parametre expandera - kako to ispitati:
1. odnijeti router u drugu prostoriju da bi signal oslabio
2. uključiti expander u blizini notebooka
3. on se pokušava zakačiti na router
4. ako lampice zaplave (a jesu) onda će on biti uzročnik excellent signala
5. da bi se potvrdilo da se notebook kači preko expandera ponoviti spajanje tako što će se ekspander isključiti - tada bi morao wifi signal biti loš

pokušao 1,2,3,4 korake - expander "zaplavio" - signal excelent

nakon toga expander ugasio - signal strength "Very low" - YES to je to expander radi posao

zaključak: expander se ne treba podešavati (to što ne možemo prići njegovom web interface-u - nije bitno

zaključak: expander se ne treba podešavati (to što ne možemo prići njegovom web interface-u - nije bitno

ostaje samo podesiti forwarding saobraćaja između router-a u stanu i wifi routera.

• Wireless-G Range Expander WRE54G

Radi se o Windoze aplikaciji, na računaru mora biti wifi kartica, ona omogućava da se podešavaju parametri expandera. Međutim, sada to nije moguće (jer su u expanderu ostali parametri 192.168.1.x) nakon što sam na routeru promjenio postavku na 192.168.45.x.

Napravio sam grešku: trebao sam prije promjene na router-u dok sam imao pristup expanderu preko web interfac-a napraviti promjenu IP-a. Ali kako se gore vidi expander radi pa to nije problem.

U principu nisam uopšte siguran da li nam ova win app treba, s obzirom da imamo pristup uredđaju putem web interface-a.
