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 <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1049466/+attachment/3886782/+files/rt3290sta-2.6.0.0.dkms.tar.gz> Edit <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1049466/+attachment/3886782> (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?
