Ubuntu – Wifi constantly disconnects, and have bad recption when it’s on ubuntu 16.10

16.10driversdual-bootnetworking

I have a HP-Pavilion-11-x360-PC dual boot: win 8.1 & ubuntu 16.10 for a few months now.
My wi-fi on ubuntu has very bad recpetion (at home and at the university, on several networks). I don't have this problem on windows 8.1.

My hardware details:
from this command:

sudo lshw -c network
 *-network                 
   description: Wireless interface
   product: RT3290 Wireless 802.11n 1T/1R PCIe
   vendor: Ralink corp.
   physical id: 0
   bus info: pci@0000:02:00.0
   logical name: wlp2s0f0
   version: 00
   serial: *I deleted*
   width: 32 bits
   clock: 33MHz
   capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
   configuration: broadcast=yes driver=rt2800pci driverversion=4.8.0-34-generic firmware=0.37 ip=10.0.0.4 latency=0 link=yes multicast=yes wireless=IEEE 802.11
   resources: irq:17 memory:90710000-9071ffff

I have tried these steps:

sudo apt-get install build-essential linux-headers-generic
cd ~/Desktop/backports-3.13-rc2-1
make defconfig-wifi
make
sudo make install

that were suggested here, because of the same wifi driver.
which weren't so successful.
They produced this repeated output:

$HOME/backports-4.4.2-1/drivers/bcma/driver_gpio.c: In function ‘bcma_gpio_init’:
$HOME/backports-4.4.2-1/drivers/bcma/driver_gpio.c:191:6: error: ‘struct gpio_chip’ has no member named ‘dev’

It didn't work at all. I will post full output if needed, don't want to be too tedious.

Also, if I restart my computer, and load the windows OS, then the wi-fi might not work on windows as well (it will not recognize any networks at all). I would have to shutdown the computer, and turn it on again.

Another problem that I have is that the computer will sometimes freeze, and then I have to turn it off manually, so it will work again. I had this problem a few times on my windows OS, and I'm not sure what's the cause of this.

Another bugging problem is that when I switch the OSes every time the clock is two hours back or forward (I'm on UTC+2 so I see why it's a two hours difference). Is there any way to fix this small bugging thing?

Thanks in advance for your help.

Edit:
The output of iwconfig wlp2s0f0 was:

wlp2s0f0  IEEE 802.11  ESSID:"someNetworkName"  
      Mode:Managed  Frequency:2.437 GHz  Access Point: **:**:**:**:**:**   
      Bit Rate=18 Mb/s   Tx-Power=20 dBm

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:4   Missed beacon:0

At the request of ThisIsNotAnId I did these two commands:

sudo iwconfig wlp2s0f0 txpower auto

sudo iwconfig wlp2s0f0 rts 2347B

and now the output of iwconfig wlp2s0f0 is:

wlp2s0f0  IEEE 802.11  ESSID:"someNetworkName"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: **:**:**:**:**:**

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:101  Invalid misc:31   Missed beacon:0

I checked it a few more times while editing, and noticed that Tx excessive retries is incrementing, and is now at Tx excessive retries:556.
I'm not sure what's the meaning of this, but it caught my attention.

Can you try the following. This is based on an Ubuntu Guide for getting the module ndiswrapper working on your system which will allow you to use windows drivers for your wifi card. I will summarize the steps here for your specific card.

Go to synaptic package manager, and install package ndisgtk. If you can't access internet from your computer, download the .deb package from here from another computer, copy to your computer, and install manually (amd64 for a 64 bit computer).

Download the windows driver from http://www.mediatek.com/products/broadbandWifi/rt3290 (Download link). Move the downloaded archive into your home folder. Create another folder named "RT3290 Driver" and place the archive in there. Extract inside this new folder. Once extracted, you should have a folder named "Disk1".

Turn wifi off. Remove all the wireless connections you have added before through network manager. That is, delete them.

I will assume you have gedit installed, or that you know how to open the text editor you do have installed from the terminal. In which case replace gedit with the command to open your editor. Run

sudo cp /etc/modprobe.d/blacklist.conf ~/blacklist_backup.conf
sudo gedit /etc/modprobe.d/blacklist.conf

This will open up that file in gedit. Go to the end of the file and add these two lines:

#Custom Blacklist
blacklist rt2800pci

Save, close, close terminal. Reboot.

Open ndisgtk, look under System > Administration > Windows Wireless Drivers. Alternatively, run gksudo ndisgtk & from a terminal.

Once open, click "Install New Driver". A dialog box will pop-up asking you to select the driver file. Navigate to the windows driver folder you extracted earlier. I'm going to assume you have a 64 bit Ubuntu installation (to check, in a terminal run uname -m. x86_64 = 64 bit, x86 = 32 bit). In your home folder > RT3290 Driver > Disk1 > drivers > Win8 > x64 > netr28x.inf

To check if everything went right, I'm going to refer you to section 3.6.2.1 of the Ubuntu Docs.

Enable your wifi if disabled, open a terminal and run

sudo depmod -a
sudo modprobe ndiswrapper

Your wifi should now be active. If it's not, reboot your computer and see if helps. If that doesn't help, remove the driver you installed using ndisgtk again and install the win7 driver and reboot and see if that helps. As a final resort, there's another driver you could try.

Then, add your wifi connection just like you did the first time.

Post back with any questions, errors, or worries you may have.

If successful, make the changes permanent by running the following on a terminal

sudo gedit /etc/modules

And adding the line ndiswrapper at the end. Save, close, close terminal.

Here's a smiley face: ?

Ubuntu – Centrino Wireless-N 1000 poor performance on N Network

Well Yes I have another solution, perhaps it could fits to your problem or not. I tried the same solution disabling the N network mode, it works but it turns out not to work under N wireless network.

In my case, I was under a WEP encrypted wireless network, this was the reason why I was navigating to slow, with N mode enabled.

Just enable your N wireless mode and change your security wireless network to WPA2 , it will resolve your problem.

regards!

Ubuntu – Wifi Connection Issues on Ubuntu 16.04

Sometimes, wireless gets disconnected because of settings in the router. First, most routers are set by default to the lowest common denominators including WPA and WPA2 auto-select, AES and TKIP auto-select and, worse of all, auto channel select. Here is a very interesting thread about auto channel select and why it doesn’t work at all well: https://superuser.com/questions/1311149/why-do-wifi-routers-do-such-a-bad-job-of-channel-selection

First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

sudo nano /etc/default/crda

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

After rebooting the router and the computer, please tell us if there is any improvement.
