Este by ma zaujimalo, ci ta wifi fungovala niekedy dobre na nejakom linuxe, a ci si to pripajal aj k inej sieti (routeru) na skusku.

A co odpovie terminal po zadani:

Kód: Vybrat vše

iwconfig

A este by si mohol sem kopirovat taku cast z lshw ako vyssie dal Kamowski,
kde sa pise o Wireless interface:

Kód: Vybrat vše

sudo lshw

Pytas sa ako sa spraval pod inymi Linuxmi:
Povodne som mal Ubuntu 14.04 - Wifi bol pomaly, tak som presiel na LM XFCE.
Vcera som experimentoval s roznymi distribuciami v live mode :
Lubuntu 13,10 : Bit rate 48-54 Mb/s
MacPup 5.2.5 : B.r -54 Mb/s
Linux Mint : B.r -48
Xubuntu 14.04 : -54
Ubuntu 14.04 : -48-54
Zaujimave, ze v live mode su tie hodnoty ovela vyssie, ako pri nainstalovanom Ubuntu alebo LM.
Pripajam aj vystup iwconfig s externym USB wifi adapterom Edimax Ralink 802.11 n Wlan - na porovnanie.

Dakujem, ze mi pomahas ale ozaj neviem, ako dalej.

Jestli to jde, tak šoupni routr na jiný kanál, pokud možno, kde je nejmenší provoz. Skanování wifi umí iwScanner http://www.kuthulu.com/iwscanner/?module=download Na notebuku ale aktualizuj ovladače i jádro, pak to nepadá a funguje to normálně.

Prvy napad bol, aby si instaloval linux-firmware a potom restart pc.
Ak ho uz mas v najnovsej verzii, a nepomohlo, tak by si mohol stiahnut zd1211-firmware-1.5.tar.bz2

Tu:
http://sourceforge.net/projects/zd1211/ ... mware/1.5/

Robalit archiv do domaceho adresara /home/tibor
cim vznikne adresar zd1211-firmware.

Potom v Terminali kopirovat nove subory do /lib/firmware/zd1211

Kód: Vybrat vše

sudo cp /home/tibor/zd1211-firmware/zd* /lib/firmware/zd1211

Restart pc.

Ak to nepomohlo, bolo by dobre zistit aj pre tie Live systemy ten vypis network z lshw ,
aby sme zistili presne na ktorom systeme s akym jadrom a firmware to funguje.
