After installing lubuntu 16.04 without a hitch - the broadcom 4311 wifi adapter is not working.

I followed the post by chilli555, here:
https://ubuntuforums.org/showthread.php?t=2214110

which identified the required driver package as firmware-b43-installer, which I installed with:

Code:

sudo apt-get install firmware-b43-installer

which seemed to go well, but after a reboot, still no joy.

Another post mentioned a need to blacklist the wl driver, which I did - still no joy.

The final part of the output from dmesg is as below:

≫ Next: help on using a free vpn setup ?

≪ Previous: (K)Ubuntu 17.04 wifi help. script posted

Hi there guys.

I'm experiencing a bit of an obscure problem, I keep (seemingly) randomly losing
network connecitvity on my PC's.

It is most apparent on my desktop PC. (Espcially if I am running it from a live
USB stick). This has been happening for a few months now, but getting progressivley
worse.

However this is just starting to affect my laptop too.

Normally a reboot or two will seem to resolve the issue for a little while.
But this is becoming more like 4/5/6 reboots in order to resolve the problem.
which is becoming quite frustrating.

My desktop and laptop are both hardwired via a switch. The modem / swtich / and cat cables
are all around 4-5 yrs old at this point.

My laptop sits on my computer desk, my desktop PC sits on a trolley next to my desk.
The cat cables are 5m in length, and its about 2.5m between the switch and the computers

I do move the trolley from time to time (to get that the plugs and what-not behind the
trolley), but there is a good amount of extra cable length, so there is no danger of
the cables being pulled out of the sockets in the switch.

I dont seem to get many dropouts when using wifi on my phone or tablet.

Troubleshooting -

1. I have re-seated the cat cables in all my devices (desktop, laptop, NAS)
2. Rebooted the (desktop, laptop, NAS)

This is leading me to think that I may have a dying swtich or dying ports on the switch.

Q1. Is there anything that I can check to determine where the issue lies ?
Q2. Am I missing anything ?
Q3. Am I best off just buying a new switch and or cat cables ?

Writing this out has just made me realise that I haven't powercycled the switch for
quite a while. (I will do this now).

Useful information:

My network set up is a follows -
Virgin media cable modem/router (downstairs)
Cat cable run upstairs to switch (upstairs in office)
PCs and NAS connected to switch (upstairs in office)

Modem:Virgin media Super hub 1
Switch:Linksys SE2500UK, 5-Port Gigabit Ethernet Switch

TIA for any help or advice.

≪ Previous: [xubuntu] ping errors

Hello,

I have an older D-Link DWL-122 USB-Wifi adapter which I want to use on Ubuntu 16.04 to connect to a local AP on 2397 Mhz.
Even though this frequency is a bit below the "normal" ISM/WiFi spectrum I was hoping this might be feasible through the prism2_usb kernel module and linux-wlan-ng firmware which is open source and can be customized.
However, I could not even get this device to work on the regular WiFi bands.
Here is what I found in the syslog:

OK, I am a very seasoned PXE Deployment person, who currently is being pushed into secure boot.

My current environment has a series of tools launched via PXE to service a number of machines. It is not practical to put them on a stick. It is not practical to disable Secure Boot. It is not practical to use PXE Linux, as we need Secure Boot and PXE Linux doesn't compile without a lot of work on any current version of Linux.

We are currently distributing out custom Windows PE Software wtih Bootmgfw.efi , launched via PXE, and that is great except it won't let us launch non Microsoft goodies, like Memtest86 UEFI, or the new Parted Magic that is Secure Boot supported. So I am looking at Grub2.

I am using the Grub2 signed from Ubuntu 14, which will load an unsigned kernel after SHIM loads it. HOWEVER, everhy signed version of Grub2 I load times out when loading the Bootmgfw.efi file. My setup is as follows:

ISC DHCP Server 4.5x
HPA TFTP Server Latest
Lubuntu Latest as DHCP server.

Test environement Hyper-V with Microsoft UEFI Secure Boot enabled, and several different brands of laptops. I am able to reproduce the problem without Secure Boot enabled as well, so we don't have to bark up that tree.

No matter what I do, here is my output from Grub. I have loaded all modules, and even loaded from the command line of Grub itself, and attached a screenshot.

TFTP Server shows a connection starts and then stops. Done with TFTPD32 and HaneWin DHCP. Problem is only with Grub, I have booted the crap out of everything with Bootmgfw and PXELINUX,but good ol Pxelinux is depreciated.

I have a Win10 and Ubuntu Mate (16.4) dual boot Lenovo Ideapad 310.
Since the install I have been unable to get the Bluetooth to work (it works in Win10). Also, I had a problem with my WIFI randomly dropping out which is now fixed (see thread at https://ubuntuforums.org/ )

The Bluetooth appears to be activated, there is an active logo in the panel and a right click brings up a functioning menu e.g. Turn Bluetooth Off, Make Discoverable... Devices, Adaptors... etc. Using the Devices option I can Search for devices but it doesnt find any, I have tested it with a Zopo and MotoG phone and a cheap Bluetooth speaker.

I have spent some time online but havent found much that addresses my problem, I did find a Bluetooth Setup page but it covers 10.04 and 11.04 so I havent tried it, https://help.ubuntu.com/ .

I have run the update and upgrade commands and I have created a current Wireless Info Script at http://paste.ubuntu.com/25637461/

Any input that can be offered is appreciated.

Regards.
