Mohammad, Your usb modem has been difficult to deal with and has had no success reports :( You are running x86_64 and it is not supported see details : There is no agrsm software support for x86_64 systems, through the modem may be supported on Intel/i386 installations, which do more slowly servce x86_64 processors Predictive diagnostics for card in bus 002: Modem chipset detected on SLOT="Bus 002 Device 012:" NAME="Agere Systems, Inc. (Lucent) Systems Soft Modem" bus=002 USBmodemID=047e:2892 IDENT=agrsm Driver=agrsm For a detailed USB cellphone usage report, see http://linmodems.technion.ac.il/bigarch/archive-eighth/msg03240.html For candidate modem in: 002 Agere Systems, Inc. (Lucent) Systems Soft Modem Primary device ID: 047e:2892 Support type needed or chipset: agrsm Writing DOCs/Intel.txt There is no agrsm software support for x86_64 systems, through the modem may be supported on Intel/i386 installations, which do more slowly servce x86_64 processors. The AgereSystems/LSI agrsm code supports compiling of a agrmodem + agrserial driver pair. There are a few different chipsets which use this driver pair, but they use different code resources: Chipsets KV* PackageNames (most current as of November 2009) ---------------------------------------------------------------------------------------------- 11c1:048c and 11c1:048f 2.6.29 agrsm048pci-2.1.60_20100108_i386.deb or agrsm048pci-2.1.60_20100108.tar.gz 11c1:0620 2.6.31 agrsm06pci-2.1.80_20100106_i386.deb or agrsm06pci-2.1.80~20100106.tar.gz !! 11c11040 (on HDA audio cards) 2.6.31 agrsm-11c11040_20091225_i386.deb or agrsm-11c11040-2.1.80~20091225.tar.bz2 !! All available at: http://linmodems.technion.ac.il/packages/ltmodem/11c11040/ Additionally there are; automation & testing agrsm-tools_0.0.1_all.deb or agrsm-tools-0.0.1-2.noarch.rpm General background agrsm_howto.txt ------------------------------------------------------------------------------------------------ * KV == latest kernel release with a reported success !! Latest update with major credit to Nikolay Zhuravlev But see conflict issue: http://linmodems.technion.ac.il/bigarch/archive-nineth/msg02753.html For the 11c11040 chip with kernels 2.6.31 and later a change in a modules loading settingmay be necessary. Within the file /etc/modprobe.d/alsa-base.conf (or equivalent for your Distro), change the phrase: options snd-hda-intel power_save=10 to: options snd-hda-intel power_save=0 or the agrsm drivers will not function. For Ubuntu related systems this can be done with: $ sudo gedit /etc/modprobe.d/alsa-base.conf Report from Bjorn Wielens: Please note- trying to load the modules on a OpenSuSE 11.2 system gives an error about the module_version symbol. Using: # modprobe --force agrmodem # modprobe --force agrserial is necessary to load the drivers, and does not appear to cause ill effects. All of the above packages are dkms competent. This means that if your Linux distros dkms package is previously installed, if provides for future updates matching forthcoming kernels. -------------- end Agere Systems section ------------------- Regards, Antonio On Tue, Aug 23, 2011 at 11:16 AM, Mohammad Javad Naderi <mjnaderi@xxxxxxxxx> wrote: > Dear Friend, > > I have a laptop with ubuntu 11.04 64bit and a Dell usb external modem. > Please help me connecting Internet via ubuntu.
