Hi everyone,

(please cc)

see $subject ...

No warning, nothing in the logs, but pinging my router I get
things like:
--- 192.168.0.1 ping statistics ---
376 packets transmitted, 315 received, +33 errors, 16% packet loss, time 405164ms
rtt min/avg/max/mdev = 0.873/10077.793/95935.698/25387.102 ms, pipe 68

or
--- 192.168.0.1 ping statistics ---
1252 packets transmitted, 1225 received, 2% packet loss, time 1252976ms
rtt min/avg/max/mdev = 0.941/764.171/19929.265/2758.225 ms, pipe 20


Has anyone *ever* seen a mdev of 25387.102 ms ???

At the same time I am pinging the same router from an iphone with a 
steady stream of 40ms or so, no problem whatsoever ...

That is with git from yesterday or so.

When you post the output of lspci, always include the -nn or -nnv switches. That 
way, we get the PCI ID. As there are several varieties of the RTL8192SE, I need 
that info. In addition, what are the details of your AP - STA configuration. 
What is the distance? Is it 802.11n or 802.11g? What is the signal strength as 
indicated by iwconfig or a scan?

No, but packets that are not returned for 19+ or 95+ seconds are usually counted 
as lost.

I have 4 different cards that use rtl8192se. With the current wireless-testing 
git, I get the following:

Card 1: Antenna config not known
--------------------------------
Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless 
LAN Controller [10ec:8172] (rev 10)

rtt min/avg/max/mdev = 1.106/2.824/107.634/10.684 ms

Card 2: Labeled 1x1
-------------------
Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8191SEvA Wireless 
LAN Controller [10ec:8171] (rev 10)

100 packets transmitted, 100 received, 0% packet loss, time 99139ms
rtt min/avg/max/mdev = 0.986/1.954/26.982/3.005 ms

Card 3: Labeled 1x2
-------------------
Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless 
LAN Controller [10ec:8172] (rev 10)

100 packets transmitted, 100 received, 0% packet loss, time 99141ms
rtt min/avg/max/mdev = 0.996/2.507/50.636/5.989 ms

Card 4: Labeled 2x2
-------------------
Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192SE Wireless 
LAN Controller [10ec:8174] (rev 10)

100 packets transmitted, 99 received, 1% packet loss, time 99146ms
rtt min/avg/max/mdev = 0.974/1.768/31.183/3.016 ms

My AP is a Netgear WNDR3300 with a max rate of 270 Mbps in the 2.4 GHz band. The 
distance between my laptop and the AP is about 2m. The card is on an Express 
Card PCIe extender, and I have 2 7 dBi antennas connected. They likely boost the 
signal more than the ordinary laptop antennas would. The iwconfig output for 
card 4 is

wlan26    IEEE 802.11bgn  ESSID:"lwfdjf-n"
           Mode:Managed  Frequency:2.422 GHz  Access Point: C0:3F:0E:BE:2B:44
           Bit Rate=270 Mb/s   Tx-Power=20 dBm
           Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
           Power Management:off
           Link Quality=70/70  Signal level=-35 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:0   Missed beacon:0

 From what you posted earlier, I think your card is like my Cards 1 & 3, but the 
PCI ID will tell for sure. These tests were run with commit 0a92aec2f22d of 
wireless-testing. There are some test patches installed, but non of them affect 
rtl8192se.

Hi Larry,

thanks for the answer, here some more information as requested

AP infos:distance: 3m

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!

Hi Larry, hi all,

On Fr, 14 Sep 2012,  wrote:

I tried now with wireless-testing from yesterday, and had the same problem.
Actually, I got even *better* results:
64 bytes from 192.168.0.1: icmp_req=75 ttl=255 time=137856 ms
64 bytes from 192.168.0.1: icmp_req=76 ttl=255 time=136848 ms
64 bytes from 192.168.0.1: icmp_req=78 ttl=255 time=134943 ms

...
rtt min/avg/max/mdev = 1.110/46967.879/137856.232/49666.671 ms, pipe 138


So now we are mdev of 50secs sometimes ;-)


Another interesting things:
At home I have the problems with the NEC router, but I am now at
the university. I am writing this email over a very very stable 
ssh link to another server.

Here is the output iof ifconfig:
$ ifconfig

          RX bytes:85599897 (81.6 MiB)  TX bytes:8925832 (8.5 MiB)


But the kernel is convinced that I am not connected ...:
$ iw dev wlan0 link
Not connected.
$ iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
          Encryption key:off
          Power Management:off


And no, I guarantee you there is no ethernet cable plugged in ;-)

I can only assume that is a problem with iwconfig/iw being too old,
although according to the output of iwconfig it is fine:
# iw --version
iw version 3.4
# iwconfig --version
iwconfig  Wireless-Tools version 30
          Compatible with Wireless Extension v11 to v22.

Kernel    Currently compiled with Wireless Extension v22.

wlan0     Recommend Wireless Extension v21 or later,
          Currently compiled with Wireless Extension v22.
