Forgot to add in the 'present status'

- After restarting network-manager things are good again only for a few
minutes after which speed again crawls to a few kbps.

[ubuntu-in] Wifi problem after ubuntu 14.04 upgrade on HP laptop with Ralink 3290 card

[Rajiv Ranjan]

Hi all,

I have reasonably new HP laptop (HP 15R006TU). I was using it nicely with
14.04 LTS till a month ago.

After some updates the wifi started giving problems like frequent
disconnections, now able to see the available wifi networks, slow speed
even when connected, poor range etc.

Sometimes booting into previous kernels helped but the problems were still
there.

I have tried almost all solutions given here.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1049466

I made fresh install of ubuntu 15.04 to see if it is fixed in newer
version. Found that it isn't.

Present status after doing this:
quote---

   - rt3290sta-2.6.0.0.dkms.tar.gz
   

Edit
   

(926.8
   KiB, application/x-tar)

Found another possible workaround if you want to use vendor's proprietary
drivers. Someone over at archlinux created a patch for mediatek's driver:
https://aur.archlinux.org/packages/rt3290sta-dkms/?setlang=ru

Original Driver:
http://www.mediatek.com/_en/07_downloads/01-1_windowsDetail.php?sn=5033
Patch: https://www.dropbox.com/s/v0kaibq0f4to0k2/rt3290sta.patch

I wrapped it up into DKMS so it can easily get rebuilt on kernel upgrades.
Download and untar into /usr/src and then run:

dkms install -m rt3290sta -v 2.6.0.0
modprobe rt3290sta

This will:
1 - Add it to DKMS tree
2 - Build the rt3290sta driver with the patch
2 - Install it to the kernel driver tree
3 - Blacklist original kernel drivers rt2x00pci & rt2800pci from loading by
creating /etc/modprobe.d/blacklist-ralink.conf

---unquote

- can connect to wifi

- range still poor

- remains connected but speed crawls to a few kbps after a few minutes

- all is good again after I do 'sodo service network-manager restart'

I talked to HP service center here in Calicut. They say they are willing to
replace the wifi card free of cost.

Anybody else with the same problem?

Any suggestions?

Re: [ubuntu-in] BSBL Broadband on Linux

Actually it is 192.168.1.1 and not 192.186.1.1. Follow the
instructions here
http://www.calcutta.bsnl.co.in/dataoneinstall/mu05.html.

I think the important thing is to configure the modem in such a way
that the username and password is entered during configuration itself.
This way when you switch on the modem it will get connected to the
internet automatically. You will not need to make a connection from
your computer and you can start browsing as soon as you switch on your
computer.

Re: [ubuntu-in] Typing in Indian Languages

[Rajiv Ranjan]

use right alt+ shift+e for ऐ and right alt+ shift+o for औ, i.e. you
have to switch to level 3 (R alt+ is the default for doing so, you can
change it to any other key combination as well by going to keyboard
preferences>layouts>options)

Re: [ubuntu-in] Tata Photon+

[Rajiv Ranjan]

I have tested it and its working fine. You have to install two small
packages viz.
1. usb-modswitch
2. usb-modswitch-data

I got the solution from here:

http://freedomyug.wordpress.com/2010/05/08/how-to-configure-reliance-huawei-modem-with-ubuntu-10-4-lts-lucid-lynx/

I googled for 'tata photon plus lucid' and got the solution on the
first page itself.

I mean Google it up yaar!

[ubuntu-in] Intro

[Rajiv Ranjan]

Hi all,

I am Rajiv Ranjan. I am working in Patna right now as an Inspector of
central excise. I am a lover of free software and I have been using
ubuntu for the last two years. I bought my computer with ubuntu pre
installed from Trivandrum.

The dealer assured me that I would be able to do almost all my work
that I would normally do in windows. He himself is an active member of
free software users group, Trivandrum and so am I. Though I used
windows to start with but switched over to ubuntu after my comp was
struck with a virus. I still have windows on my comp but I hardly ever
use it and so does my wife.

Since then, it has been a long journey. I still have windows on a
partition of my comp but I hardly ever use it and so does my wife. I
have learnt so many things about the internal working of a computer
and, of course, linux.

I hope I will be able to help those switching over to linux with my experiences.

Cheers

Rajiv
