TECOM WL5061DP usb wireless problem [SOLVED]

[salixcylic]

Width Zydas I get this info:
iwlist wlan1 scan

Code: Select all

Cell 02 - Address: E0:91:53:03:BE:5E
                    Channel:6

and when I'm conected, an iwconfig give this:

Code: Select all

          Mode:Managed  Frequency:2.437 GHz  Access Point: E0:91:53:03:BE:5E

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

I hope this "table" can help you to compare both:

Code: Select all

             iwlist                                                         iwconfig

p54    |       Extra: Last beacon: 649ms ago  |     Link Quality=70/70 Signal level=-129 dBm |

Zydas  |      Extra: Last beacon:  823ms ago  |    Link Quality=39/100 Signal level=39/100   |

How do you compare -129 dBm width 39/100 ?
I think you are right: it's time to try Windows driver with ndiswrapper.
Thank you.

Ok, I've downloaded the Windows driver from here: http://www.jazztel.com/archivos/descarg ... rivers.zip
I've unzip the file and click in Salix - System - Ndiswrapper Wireless Drivers. Then I've install the new driver (wlusb20.inf) and now I'm connected with wicd. Better signal and no problem.
iwlist wlan0 scan gives this:

Code: Select all

Cell 02 - Address: E0:91:53:03:BE:5E
                    ESSID:"WLAN_EE"
                    Protocol:IEEE 802.11g
                    Mode:Managed
                    Frequency:2.437 GHz (Channel 6)
                    Quality:51/100  Signal level:-63 dBm  Noise level:-96 dBm
                    Encryption key:off
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
                              9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
                              48 Mb/s; 54 Mb/s
                    Extra:bcn_int=100
                    Extra:atim=1

I don't know why those "Extra" lines are different than the others receivers give, but they work.

And after connected an iwconfig gives this:

Code: Select all

wlan0     IEEE 802.11g  ESSID:"WLAN_EE"  Nickname:"darkstar"
          Mode:Managed  Frequency:2.437 GHz  Access Point: E0:91:53:03:BE:5E   
          Bit Rate=48 Mb/s   Tx-Power:20 dBm   
          RTS thr:2347 B   Fragment thr:2346 B   
          Encryption key:off
          Power Management:off
          Link Quality:50/100  Signal level:-64 dBm  Noise level:-96 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Conclusion: GNU/Linux firmware isl3887usb gives worst performance than Windows driver + Ndiswrapper. If you are using a wireless lan that is near you, maybe isl3887usb can works ok, but if you are using the neighbor's wireless lan, better use Ndiswrapper.

Thank you very much to all of you that have help me to make this works ok: thenktor, gapan, pwat and shador. I've learned a lot about wifi commands, wicd and Ndiswrapper. I hope this thread is useful to other people.
