wifi and bluetooth not working

[kiran_online]

The wifi signal of my laptop is very low and I am unable to connect to any wireless network, I am unable to switch on the Bluetooth. I tried switching to windows but the problem persists. So, I switched back to ubuntu again. The problem still persists. I tried updating drivers but did not work. Need help.

Hi

Could the antenna be dis-connected, as the problem seems common to both OS's?

My usual response to a Linux WiFi problem is ....

When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to this link and follow the instructions there on how to the run wireless script without an internet connection.

Actually, I tried all the possible solutions. I think it is an issue with my wireless card. Is it possible to replace the wireless card or i need to buy USB wifi adaptors and Bluetooth adaptors?

Here is the wireless-info.txt pastebinit link.

Hi

Do you need WiFi?

You have a WWAN card, WLAN card and Ethernet?

So you are trying to hotspot via the WWAN card to a mobile signal?

You have WiFi powersave enabled, this could limit the strength / speed.

Is there a closer DNS server than 8.8.8.8 / 8.8.4.4?

I would try a live version of Lubuntu, run from USB without all the extra 172.x.x.x networks etc, and see if just the WiFi alone will actually respond.

Actually, I want to use both the wifi and Bluetooth on my laptop. previously I was able to use both, but I can't use them now. I am not a technical guy so I could not get your previous reply. can you simplify the steps which will help me to use both.

Hi

NO not really.  My questions still stand...

Do you need WiFi?

So you are trying to hotspot via the WWAN card to a mobile signal?

#####

You appear to have a 'bridge' to a WWAN card.

NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

Please Download the Updated Driver (Big Thanks to Jim Colaco) From Here or Here. Tested on Ubuntu 16.04 and 16.10.

Type in the following commands....

sudo tar -xvf rt3290sta-2.6.0.0.dkms.tar -C /usr/src
sudo dkms install -m rt3290sta -v 2.6.0.0 --force
sudo reboot

You are using a 2800 series driver.  From ???

rather than an Ubuntu one?

So perhaps one step at a time?
