Zdravim. Hladam nejake rady odhladne vybudovania Acces pointov na Linux PC. V prvom rade ma zaujima ci je to dobra volba lebo lepsie je nechat hardwarove APcka. Ide o to ze momentalne mam vykrivac kde su uz 4 anteny,a v poslednej dobe uz zacinam mat problem ked sa pripoja vsetci useri, zacnu tahat z netu tak im to nejde naplno ako by malo, jednoducho APcka nestihaju trafic. Preto rozmyslam vymenit Apcka za nejaky PC z linuxom, 4 wifi karty dufam ze to bude lepsie. Co vyt na to ? Bude to lepsie alebo nie ? Dalej aky hardvare a OS pouzit ???? Poradte nejake dobre stabilne odskusane zariadenia a OS k nim....
Dik za info

myslim, ze tato otazka tu bola preberana uz 1000x, skus pohladat.

linux na PC je sice pekne riesenie, ale treba uvazit nasledovne:

1. vysoka spotreba energie (mesacne cca 500-600 sk) aj pri najlowpower rieseni (ktore zasa je cenovo tak drahe, ze uz sa oplati kvalitne AP)
2. problemy s vyssim poctom kariet (zdielanie preruseni)
3. problemy s miestom a napajanim

Ja osobne preferujem kvalitny HW priemyselny pocitac s proprietarnym OS urcenym na AP (STAROS,MIKROTIK, specialne verzie LINUXu) a to:

ALIX 2xx, RB 5xx (532A), WAR boardy, specialne INTEL PC.
Kompletne vybaveny point (vratane UPS, GSM watchdog a pod) ta vyjde cca 10000 SK (podla konfigu) bez anten, spotreba 200 SK/mesiac.

dalsou moznostou je tam dat par sektoriek, par lacnych AP a radovat sa z toho, ze to uz 1 tyzden nezatuhlo.

PII 350MHz, CF karta namiesto disku, linux voyage

tri CM9 karty (len tri vojdu, kedze to ma 3 pci sloty), onboard intel sietovka

45mbits traffic, 200 iptables, 60% CPU vytazenie, latencie 0.35ms, v plnej zatazi 1.3 ms

spotreba 40W = mesacne pri najvyssej sadzbe (20 korun istic, 5.5 za kWh) = 20+163=185,-
