Sony Vaio, Mint XFCE 13 and the "weak" wireless signal

Postby ichiSiD on Fri Nov 30, 2012 7:34 am

Hello to everybody… I'm new on this forum, thus I would greet all the people around here!! :)
I'm typing from Italy and I'm a Minty user by a lot of time and… I loved this distro at the first sight.
I used it without any problem over a bunch of PC but now, unfortunately, I'm having some problem with my "new" netbook and his wireless card. The laptop is a Sony Vaio VPCM13M1E to which I have given a new soul putting the Mint 13 XFCE (32bit) on. Everything works properly, but the wireless card (Ralink RT3090) seems to have "low power". I mean: if I place the netbook close to the router (50 cm) it reach easily the signal and it connect to the wireless with no problem and I can navigate on internet without any disconnection, but if I move the laptop -for example- 1,5 meters far, it lose the signal and it seem that it can't (and don't want) connect again.
So I have tried to use a wifi-usb dongle (model: Atlantis A02-UP3WN v1.0 which it seem to have a Realtek chip). Mint recognize it, but also that seem don't work. Previously, when M$ Windows 7 Starter was installed (I used that for about 15 minutes just for trying it), the integrated card gave me the impression of be "not so strong" and for by-passing that problem (I was thinking would be driver related), I used this dongle and it worked with no problem.
Oh.. I've tried also another dongle that a my friend lent me but, unfortunately, seems that this second dongle isn't very friendly to install on Mint. In fact is a Netgear WNA3100 and looking around this forum I have found that many others Mint user have had problem to make it work.
Thus… since I'm going crazy trying to make the wireless work just a little better, I come here (in pace!!) with the hope to find somebody (that I don't use to know) who could help me.
Giant thanks!!!
(And I apologize for my bad english, but I'm a bit (?) rusty with it… if I have make some biblical/nasty/yaowww error, please correct me!!)

Ciao!!!! :)

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

[Edit] your original post and add [SOLVED] once your question is resolved.

“The people are my God” stressing the factor determining man’s destiny lies within man not in anything outside man, and thereby defining man as the dominator and remoulder of the world.

First of all: thanks for the answer!
Then... I followed this part of the guide you linked me:
Guide from bug 896582 wrote:
WORKAROUND: In release prior to Precise, I installed this driver: https://launchpad.net/~markus-tisoft...0~ppa1_all.deb
It did not work with newer driver.

Blacklisted "acer_wmi" in /etc/modprobe.d/blacklist.conf

Added "rt3090sta" to /etc/modules

Original source: http://ubuntuforums.org/showpost.php?p= ... stcount=20

WORKAROUND: In Precise, once the Ralink driver is downloaded, unpack and edit the file ../common/cmm_wpa.c :

Code:

UCHAR PrimaryRsnie;
BOOLEAN bMixCipher = FALSE; // indicate the pairwise and group cipher are different
UCHAR p_offset;
- WPA_MIX_PAIR_CIPHER FlexibleCipher = MIX_CIPHER_NOTUSE; // it provide the more flexible cipher combination in WPA-WPA2 and TKIPAES mode
+ WPA_MIX_PAIR_CIPHER FlexibleCipher = WPA_TKIPAES_WPA2_TKIPAES; // it provide the more flexible cipher combination in WPA-WPA2 and TKIPAES mode

then lastly in the file ../os/linux/config.mk :
Code:

HAS_GREENAP_SUPPORT=n
#Support MAC80211 LINUX-only function
-HAS_CFG80211_SUPPORT=y
+HAS_CFG80211_SUPPORT=n

#Support RFKILL hardware block/unblock LINUX-only function
HAS_RFKILL_HW_SUPPORT=y

Run "sudo make ; sudo make install", blacklist "acer_wmi" in /etc/modprobe.d/blacklist.conf , and you should have a working built module/driver.

It's helpful to blacklist rt2800pci so the system doesn't use this - it will use the new rt3090sta/rt2860 instead after a reboot...


The only thing I changed is that I hadn't blacklisted of the "rt2800pci" in the last line of the guide because by blacklisting that the wifi don't work at all.

Unfortunately the problem remains: if the laptop is more than a 1.5 meters far from the hotspot it lose the signal.... :cry:
