Hi RYTCL
... 2 ERROR lines related to rtl_nic persists. ...
You can ignore them. It just means it didn't find the firmware in the first place it looked.
... 'unable to load firmware' error has disappeared. ...
That means it found the firmware.
... May be some other driver(s) are conflicting with my WiFi card "Ralink RT3290 - rt2800pci " ...
No.
... It clearly shows rt2800pci is the correct driver ...
That only tells half of the story. Here's part of the config file for our kernel:
CONFIG_RT2800PCI=m
CONFIG_RT2800PCI_RT33XX=y
# CONFIG_RT2800PCI_RT35XX is not set
# CONFIG_RT2800PCI_RT53XX is not set
# CONFIG_RT2800PCI_RT3290 is not set
It shows:
1. The rt2800pci was compiled as a loadable module.
2. The rt2800pci has rt33xx chipset support compiled in.
3. The rt2800pci does not have rt35xx chipset support compiled in.
4. The rt2800pci does not have rt53xx chipset support compiled in.
5. The rt2800pci
does not have rt3290 chipset support compiled in.The only way to fix that is to reconfigure and recompile the kernel and recompile the driver.
