[Solved]Connecting To WIFI On HP Computer

Post by shom_ronnie » Tue Jun 12, 2018 1:58 pm

I am new to linux systems, dint know where else to post my problem, so dropping in here

I recently switched from windows, and my hp works fine, its just the wifi that seems to be the problem. Wifi keeps fluctuating, and drops completely at times and cant access any pages then. Problem persists for a while unless the wifi button is toggled. I tried a couple of steps in other posts without much success. Would be really glad if someone could help me out here. Thanks in advance

You could try some of the ideas in this article from the Easy Linux Tips Project. You'd probably want "Section 2: Bad wireless connection", but the entire page is informative.

Also, it could be helpful for others if they knew more about your system. If you entered inxi -Fxz an a terminal prompt, and posted the output here, it would help facilitate diagnosis.

You have a broadcom card you'll need to plug into a ethernet connection (hard cable) and install the driver for that card then reboot.
The driver manager under Menu/Administration/Driver Manager should offer you a couple possibilities , install the recommended driver.
According to the inxi output you already have the wl driver installed and it should be working
please go to a terminal and enter this command and post the results here:

Code: Select all

rfkill list
and

Code: Select all

lsmod | grep wl

Looks like your wifi is BCM43142. Here's a couple of threads on that:

Ok so i installed the broadcom driver. But the wifi button is gone now, no other way to turn wifi on. It only shows wired connection. With rf kill command it says
0: hci0: bluetooth
Soft blocked: yes
Hard blocked: no
Does not give anything with lsmod command

So basically i am back to where i began. Looked in the driver manager, installed the recommended driver, and wifi is back on, but keeps fluctuating, although i am metres away from my router, It gets slow to the point where it gets disconnected and then re connects

Ok here something you can check
go to terminal and type

Code: Select all

iwconfig

look for a line that says power management if it says on try turning it off with this command

Code: Select all

sudo iwconfig wlp13s0 power off

see if that helps if it does let me know we will make it permanent.

Just an update, from last night the connection hasnt dropped completely, although it keeps fluctuating. Dont know if that has an effect on the speed of browsing. Sometimes its at 88% then drops to say a 40%. Dont know if this will stay, but its how it has been last one hour of usage.

0nly other thing I can think of is that your router is in a very congested area and your all trying to use the same channel. On my neatgear router I can tell it to use a different channel you might see if you can do the same there. That may increase the signal level a bit and speed this up. This page may be of help:

Thanks for your help. Think reinstalling the driver did the trick. For now the connection does not disconnect completely as it was doing previously. But i am still skeptical about this, as network does not seem stable although i am getting uninterrupted internet. I will keep monitoring, and report of required

Thank you

Its solved the issue. Wifi does not drop off as it was doing earlier. Signal fluctuates a bit, but does not affect internet speed. So i am happy with it. Will be marking solved

Just to update, the wifi connection dropped again, and i had to manually disconnect and then reconnect. But while doing so i noticed something else, there was a lag in my system, and nothing else is open other than a file that i am copying to my pendrive. Its a large file of about 9gb. Why i am saying this is because for all these while everything seemed fine, just after i started copying the file wifi became erratic, and my computer overall went slow. The interesting part is when i first nioticed this problem the other day, then too i was copying a file to my pendrive, a similar sized file.Is there a possibility of the two being linked in some way.

If you're doing the copying of such a large file via a file manager like Nemo, it could be. Recommend using the command line cp, or the lightweight GUI xfe, for copying files that large, especially to/from external devices.

ok, but this is a bug dont you think and needs to be fixed. Copying files is an essential part of computing right, and a bug of this nature can be frustrating. Anyways i will mark this thread as solved, because wifi isnt the issue anymore, its copying files so.

As i have been monitoring without any copy on in the background, it seems like copy isnt causing the issue. Its like the wifi actually looks connected, but in reality its not. Web pages dont open up, it keeps buffering and then after a while the page opens with full speed. Its like a dropping internet connection, only thing is my internet works fine on all other devices. Its just my wifi on this laptop that seems to be the prob. Any ideas whats need to be done. Pls help, really need to get this solved

Ok there are a couple other possibilities. 1. if you installed with secure boot activated. It may interfere with the wireless card some have reported that with your card if you do have secure boot turned on then the card will not work at all or may work partially and be unreliable. so check that first.
2. Also some have reported that your particular card bluetooth interferes with wifi functionality and can cause the problems your experiences. I have no way of checking out ether one of these since I have no machine with that particular card installed. But it may be worth checking out.
3. Also some cards not sure yours is one of them have two antenna ports available but only use one connection. If that is the case switching to the other antenna connection may work.
