Linux Mint 18.3: sudden problem with Wifi

Post by AntonioB » Fri May 11, 2018 10:16 am

Hi all,

today I have a problem with Wifi connection on my laptop (HP Pavillon DV5 - OS Linux Mint 18.3):
even though Wifi switch is enabled, no connection are available (with another device I correctly see wifi network available).
Problem appeared without update, I have problem with driver?

What command are necessary for check state of my Wifi Driver? I have Broadcom 4312...

Thanks in advance for reply.

Tony

What channel is the wireless router currently using? Most broadcom chipsets can't use over channel 11 on 2.4 Ghz

Hi,

Wifi connection now unexpectedly working fine, I run anyway your useful script and the respective URL is --> http://termbin.com/kckk.
I don't know the reason of this behaviour (probably there is a problem on Routing, but I don't change nothing).

Cheers,
Tony

Wifi power management is on, turn it off with

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service
If you have any more issues you might want to switch back to the open source module

Code: Select all

sudo apt-get install firmware-b43-installer && sudo apt-get remove bcmwl-kernel-source

Hi Antonio and Jeremy,

I have similar problems with my wifi at my Asus 704A laptop. Wifi suddenly drops from time to time. Using Mint 18.3 Xfce. After about 1 minute the connection recovers.

Question: I have changed content of /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf to

[connection]
wifi.powersave = 2


After boot power management is off now but when I put my laptop asleep and wake it up power management is on again. How can I solve this?

For now I will not use sleep mode and see if power saving off helps to prevent wifi drops.

Kind regards, Folkert

I think ASUS is a piss poor product, the majority of the WiFi issues I see on this forum of late are from folks using ASUS laptops.

Code: Select all

System:
 ASUSTeK (portable) product: TP500LA v: 1.0
           Mobo: ASUSTeK model: TP500LA v: 1.0
           Bios: American Megatrends v: TP500LA.203 date: 06/11/2014
 MEDIATEK MT7630e 802.11bgn Wireless Network Adapter
           driver: mt7630e

All day long today, my WiFi has been dropping out, then later....... later... it hooks back up.

just now, I got tired of the mess and plugged in my Panda PAU06 USB WiFi adapter, and it has not missed a beat.
I disabled the internal MediaTek adapter

Ralink RT5372 Wireless Adapter driver: rt2800usb

This one does not drop out.

The problem is that in the past with Windows 8.1 it never dropped out. Linux Mint is way better than Windows in all aspects except the wifi dropout problem.

My builtin adapter is running with the rt2800 driver but an external usb wifi adapter from D-Link running the rt8188eu driver has the same problem.
So now I'm gonna try disabling the power management to see if this helps.

Panda adapters are not for sale in the Netherlands. If I buy one at ebay I pay $11 for the adapter and $24 for shipping by UPS :-(
