Problems associating with wireless adapter [RTL8188CUS]

Hi, fellow archians.

I'm currently having problems getting my NetGear WNA1000M with the RTL8188CUS chipset to work. The wired connection works fine with the same router. What I've done so far:

lsusb:

Bus 001 Device 002: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS]

I assumed the RTL8188CUS chipset went under the same module as rtl8192cu, and the dmesg for that returns:

dmesg | grep rtl8192cu:

[    6.139617] rtl8192cu: rtl8192cu: Chip version 0x10
[    6.223612] rtl8192cu: MAC address: c4:3d:c7:78:99:cf
[    6.223615] rtl8192cu: Board Type 0
[    6.223623] Loading firmware rtlwifi/rtl8192cufw.bin
[    6.223913] usbcore: registered new interface driver rtl8192cu
[    8.648609] rtl8192cu: MAC auto ON okay!
[    8.681239] rtl8192cu: Tx queue select: 0x05

To my understanding, this should at least be in order. Then comes the setting up of the actual wireless:

ip link set wlan0 up
iwlist wlan0 scan:

dhcpcd[948]: wlan0: waiting for carrier
dhcpcd[948]: timed out
dhcpcd[948]: allowing 8 seconds for IPv4LL timeout
dhcpcd[948]: timed out

There's no difference if I choose to use dhclient. Wicd gets stuck on "obtaining ip address", so I assume there's something other wonky going on.

Any help/diagnose is appreciated!

Re: Problems associating with wireless adapter [RTL8188CUS]

check dmesg

Ah, this is the output of dmesg: http://pastebin.com/1mMuuqSB

However, it turns out that if I leave the computer off for a while, it's able to connect to the wireless network. However; if I reboot the computer, it's unable to do so. It refuses to give me an association point, if that's the case.

For what it matters; the router recognizes it's existence.

BSSID 	Associated 	Authorized 	SSID
C4:... No              No               dlink  

I'm honestly at loss.

Re: Problems associating with wireless adapter [RTL8188CUS]

Hi. 

I've had some association problems with this adapter also.  Although I can't claim to know exactly what happens, it seems like the device gets into a certain "state" where you must remove the power (unplugging or shutdown) to use the adapter again.  I use netcfg to bring up my connection automatically at boot, but if a situation occurs where I must disconnect, I have to replug the usb device in order to reconnect to the network with netcfg - or shutdown and power back on. 

I would suggest just unplugging the device for a couple of seconds and plugging it back in - then trying again.  I hope this helps - not sure if this is your exact problem, but I think it's caused by the same underlying issue with this hardware or driver.

Re: Problems associating with wireless adapter [RTL8188CUS]

Hi, I'm having similar problems with the rtl8192ce module (i.e. the connection time out at the authentication stage) (bugtracker)
A solution for me was to disable the power saving features as explained in this post: https://bbs.archlinux.org/viewtopic.php … 3#p1107433
Can you check if a similar hack works for you?

It looks like the ips and fwlps options don't exist for the rtl8192cu module.  I have noticed that if I just unload and reload the module, it gets around my problem, but it would be nice to find an equivalent hack for this module, if that is indeed the issue.  modinfo didn't give me much in the way of specifying a equivalent options.
