My daughter’s PC drive burned out, and I decided to “upgrade” to oS 11.1/KDE3.5, previously she was using 11.0/KDE3.5 with a wireless TP-Link tl-WN321G USB adapter with reasonable performance.
After the upgrade I couldn’t make the USB thing work (no option for WPA-PSK encryption, maybe an old or bad module), so I decided to install a brand new PCI card I got 3 months ago as a warranty replacement for a defective one. I posted about that here: wireless netgear usb wg111v2
The thing didn’t work at first, and yast network device config module gives a weird message when I tried to configure the card:
It was not possible to configure the network card because the kernel module (eth0, wlan0) is not present. This normally occurs when the firmware (for wireless devices) is missing. See dmesg output for more info.
And the EDIT button is grayed out (the above is translated from pt_BR, so it may not be 100% literal).
The weird part is, AFAICS, there’s no need to install the firmware for this, and the rtl8180 module is loaded. Some info:
# lspci |grep RTL
01:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller (rev 20)
# lsmod |grep rtl
rtl8180 31560 0
mac80211 241664 1 rtl8180
eeprom_93cx6 2584 1 rtl8180

# uname -rv

iwconfig only reports lo and eth0.
OK, almost quit, then decided to reboot. Of course it worked, all normal, and I could configure the card in Yast, associate to the AP and browse the web in firefox, update some unrelated packages (desktop-texts and gwenview). After about 15 minutes of inactivity the network monitor (knetstats) panel icon show the card is disconnected, and it stayed that way. Yast network device shows the previously configured cad as inactive and a “new” card (the same) unconfigured. I deleted the inactive card and rebooted, but now yast tell me the same thing about “kernel module (eth0, wlan0) is not present”.
But dmesg gives:
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 19
vendor=10de device=03f3
rtl8180 0000:01:0a.0: PCI INT A -> Link[LNKC] -> GSI 19 (level, low) -> IRQ 19
0000:01:0a.0 (rtl8180): Unknown RF! (0x0)
vendor=10de device=03f3
rtl8180 0000:01:0a.0: PCI INT A disabled
Could this be an IRQ assignement problem? I grepped (this verb exist?) for IRQ 19 in /var/log/boot.msg but got the same as in dmesg.
Any suggestions will be greatly appreciated.
