If you run " iwconfig " in a terminal, how much is tx-power ?

Hi fredk661682, thank you for answering me.
The Tx-power shown is 20dBm

Actually the whole message on the wlan0 side is:

wlan0 IEEE 802.11bgn ESSID:"xxxxyyyyzzzz'
Mode:Managed Frequency:2.432 GHz Access Point : F3:...........
Bit Rate=0 fct/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off
Power Management:on
Link Quality=47/70 Signal level=-63 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

What does this say to you, anything usefull?

[fredk661682]

I see you are connected to ESSID:"xxxxyyyyzzzz' with Encryption key:off .
Did you enter a password ?
Can you run " iwlist scan " in a terminal to see if the access point : F3......... has "Encryption key:off "

Thank you fredk661682!

Yes, I did enter the password, no doubt about it. I do not understand that thing with "Encryption key:off". The key must have been definitely on, Puppy has asked me for the passphrase. Also, I have tested the wifi connection in Windows on the same netbook and I have been asked for the passphrase.
The network security was supposed to be set for WPA2-PSK with AES, why the key that has been given to me would not be on? Would that be possible to have the encryption key off on the router and yet being asked for the password on the netbook?

I will run that "iwlist scan" only in a few days when I will get to that place again.

Which are the equivalent windows commands for these Linux "iw config" and "iwlist scan" that you have given me, please? Being again in that location I would like to run the same diagnosys under Windows, where the netbook is working OK on that wifi network.
Then maybe we can understand better what is going wrong. Thank you!

I think I'm having the same issue, ran the iwconfig and it showed :

Code: Select all

wlan0

Then I ran iwlist scan

Code: Select all

I'm literally coping it by hand from one screen/computer to another, so I may have made some mistakes and I got lazy at the end and didn't put it all (IE: Unknown, etc), but let me know if you need that.

I've tried the three different connection managers (Barry's Simple, Frisbee and Network Wizard) and they generally give me the same results, connection but no actual internet connection. This computer I'm writing from is using sabayon (gentoo) and is connecting to the same wireless router.

Thanks in advance for any help.

Is that trying to connect wide or double wide?? IE 130Mbps or 270Mbps.
I had trouble with mine above 54Mbps.
Mine was the NIC and driver combination. I bought a different NIC.

[kevins]

not sure how I would find out if it was wide or double wide, I do know its an internal card and i think its using a PCI-e slot

[Burn_IT]

You look at the router settings from its web interface.

[fredk661682]

It seems that the Encryption key from iwconfig is not the same then the Encryption key from iwlist (http://linux.die.net/man/8/iwconfig). Sorry

Do you have an ip address (inet addr) ? : you may run " ipinfo " in a terminal or left click on the network icon.
If yes, you may run " ping <your inet addr> " to see if something is transmitted, or try " traceroute google.com " (ctrl c to stop)

# ping 192.168.182.11

I see also " Bit Rate=0 fct/s ": you may try to change it by " iwconfig wlan0 rate 2M ".

[kevins]

so I checked for the IP and had an internal router assigned one and tried to ping it and got 100% failure on that. Wanting to try everything before reposting I did the wconfig wlan0 to 2M and that seemed to work, just as a test, brought up a website and bingo, I think that last thing did it.

thanks a lot! Hope this helps the OP too.

(From a previous post, I don't have access to the router web config so I wasn't able to find if the connection is double or single wide)

[fredk661682]

Thanks for the explanation, Kevins.

Axelpuppy, I don't know about windows, but you may try Xubuntu 13.10 (linux), it is often updated and you can try it from a DVD whithout installation.
