TOTOLINK N150UA-B doesn't work

Hi,

I buy a TOTOLINK N150UA-B usb wireless adapter recently but it doesn't work under Arch Linux.

When I type command "lsusb", it shows:

Bus 002 Device 024: ID 0bda:1a2b Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (Driver CDROM Mode)

I googled for that and I found I have to install a package called "usb_modeswitch" to switch the mode.

After package "usb_modeswitch" installed, lsusb shows:

Bus 002 Device 010: ID 0bda:2005 Realtek Semiconductor Corp. 802.11n WLAN Adapter

It seems that wireless adapter's mode has been changed successfully. But command "ip link" still show me nothing

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 00:e0:4c:68:03:23 brd ff:ff:ff:ff:ff:ff

I loaded all the possible Realtek wireless modules but it still doesn't work.
Any suggestions about this problem? Thanks in advance.

Re: TOTOLINK N150UA-B doesn't work

I found this driver maintained by Igor Mokrushin.
After a little modification, my usb wireless dongle works now.
Thanks to Igor Mokrushin!

os_dep/linux/usb_intf.c

#ifdef CONFIG_RTL8710B
        /*=== Realtek dongle ===*/
        {USB_DEVICE_AND_INTERFACE_INFO(USB_VENDER_ID_REALTEK, 0xB711, 0xff, 0xff, 0xff), .driver_info = RTL8710B}, /* 8710B = 8188GU 1*1 */
        {USB_DEVICE_AND_INTERFACE_INFO(USB_VENDER_ID_REALTEK, 0x2005, 0xff, 0xff, 0xff), .driver_info = RTL8710B},
#endif
