No wifi in natty. Speedtouch 121 g

[Javier]

### Fixed in 2.6.39-rc7 ###

After upgrade from maverick to natty, i can't see the list of available wifi networks. I have a Speedtouch 121g USB dongle. In maverick i had to install linux-firmware-nonfree to get it running, but it doesn't work in natty.

Bus 001 Device 004: ID 06b9:0121 Alcatel Telecom SpeedTouch 121g Wireless Dongle

The result of dmesg is:

[ 33.242642] ieee80211 phy0: p54 detected a LM87 firmware
[ 33.242645] p54: rx_mtu reduced from 3240 to 2384

Hi,

no, i haven't fix it.

I can confirm that the dongle works in a maverick updated system, but still doesn't work in natty (updated yesterday).

[Fabio Marconi (fabiomarconi)]

hello Javier
your system is 32 or 64 bits?

[Javier (javiersmail)]

32 bits.

If any extra information is needed, feel free to ask. I don't know where to find useful information, but if you indicate me a file or a command, I'll be pleased to provide the information.

Yujuu!

It works!, and apparently doesn't break anything.

Just one more question, how can i keep up tp date this pakage?

Thanks a lot!

[Fabio Marconi (fabiomarconi)]

Hello
This is the most advanced kernel, and it will be shipped with Oneiric.
Sincerly I don't know but probably the system has to suggest that is trying to install an older version, but in case it is intalled and not working simply reinstall this version.
Thanks for the reply

Apparently, I have the same problem:
 -Upgrade from maverick to natty
- Cannot access anymore to (wpa-psk) wifi networks (networks not detected on scan results)

Computer Dell Precision M4500 with a Broadcom BCM4313 wireless card

Perhaps that the v2.6.39-rc7_oneiric kernel fix my problem too, but I cannot check if it's true, the amd64 version is not available...
