Hi Larry,

thanks for the answer, here some more information as requested

AP infos:distance: 3m
NEC Aterm WR8600N ATERM-B45459
firmware 1.0.11

Network card is built in into a Lenovo Thinkpad Edge
# lspci -nnv -s  03:00.0
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller [10ec:8172] (rev 10)
	Subsystem: Realtek Semiconductor Co., Ltd. Device [10ec:e020]
	Flags: bus master, fast devsel, latency 0, IRQ 17
	I/O ports at 2000 [size=256]
	Memory at f0500000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [40] Power Management version 3
	Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Legacy Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [140] Virtual Channel
	Capabilities: [160] Device Serial Number 88-55-22-fe-ff-4c-e0-00
	Kernel driver in use: rtl8192se

# iwconfig wlan0

          Mode:Managed  Frequency:2.442 GHz  Access Point: 00:3A:9D:B4:54:5A   
          Bit Rate=150 Mb/s   Tx-Power=20 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:9   Missed beacon:0

at this point there is according to ifconfig/iwconfig a connection 
up and running, but ping tells me:
# ping 192.168.0.1
...
>From 192.168.0.2 icmp_seq=77 Destination Host Unreachable
..

I tried with network-manager as well as without and wpa_supplicant
directly, no change.

Also removing the module and reloading it did not help.

I think it is pretty standard WPA-PSK, is there anything more I can
tell you, please let me know.

See above.

I am running on top of default kernel git, will try wireless-testing, too.

Thanks a lot and all the best, and let me know what I can provide more!
