No WIFI, like others

bcripps · Post by **bcripps** » Sun Jul 31, 2016 10:37 am

Just downloaded Mint 18 Sarah yesterday using USB Universal Installer, (no disc burner).

Download and install went fine but can't connect to a WIFI hotspot. No internet at home so rely on hotspot at Wendy's Bar.

I can see the available hotspots in the vicinity and select Wendy's and enter the password. It seems ok but Firefox can't find a server.

In Device Manager, it says that drivers can't be installed and to reinsert the USB stick. I did that and thought I installed a driver, but apparently not.

Someone on form suggests setting up a Profile in Network Manager before downloading a driver. I don't see that listed.

I'm sure there is a simple fix for this. Hope someone can help.

Thank you,
Bry

reinsert the USB stick

Please post output of these commands:

Code: Select all

lsusb
sudo lshw -C network

Thanks for your reply Flemur, but this is the newbe section of the forum and you'll have to forgive me, but I need specific instructions here.

Insert memory stick: before I turn on the computer and repeatedly press F12? Or after I have booted up Mint?

And these commands? Where do I type them?

I know your time is valuable, but please be a little more forthcoming so I can provide the information you require.

Once again, thank you. I do appreciate your assistance.

Hit Ctrl+Alt+T to open the terminal and paste the commands there (using middle mouse button or Ctrl+Shift+V)

I don't think that is the problem as the lshw results show that the wl module is loaded. The secure boot issue keeps the module from loading and we would likely see

Code: Select all

network: UNCLAIMED

in the lshw results. Bcmwl-kernel-source has seen better days and it has not been performing well in Ubuntu 16.04

bcripps · Post by **bcripps** » Fri Aug 05, 2016 10:22 am

Okay. Would like to try Chilli555's solution of turning off the Secure Boot.

“It appears that the only solution so far is to enter the computer's BIOS and turn off Secure Boot.
Secure Boot is a security standard developed by the PC industry to help make sure that your PC boots using only software that is trusted by the PC manufacturer”

But can't figure how to enter BIOS. F2 doesn't do it. Computer is a Lenovo ThinkPad 11e with no disc drive.

Thank you both for your comments.

Is there someone at this Wendy's that you can watch access the internet? I suspect they are using a redirect to a webpage for you to agree to their terms and conditions and firefox isn't working with it. The next time you try to connect there use

Code: Select all

route

and it should show a gateway IP, enter that into the browser window and see what happens

bcripps · Post by **bcripps** » Sat Aug 13, 2016 10:00 am

Thanks Jeremy.
My second computer with Win 7 connects to Wendy's just fine. But I don't use Firefox; I use the Midori browser. Others here do use Firefox though, without problem. And my Internet Explorer works fine, when I use it.

I entered “route” and tried to take a screen shot but the forum responded saying the file was too big to be included as an attachment. But here's what I got: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface

Hope that means something to you. I'm at a lose. And I'm not sure what you mean when you say “enter that into the browser window”

Sorry for being a dolt, but I guess I am...

Thanks again,
Bry

Post by **JeremyB** » Sat Aug 13, 2016 10:48 am

So in windows7 do you have some screen after connecting to Wendy's in the browser to agree to conditions or do you have internet immediately?

It seems that you connect in LM but get no DNS or that route command would have shown you IP addresses, here is what mine shows when connected

Code: Select all

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.1.1     0.0.0.0         UG    600    0        0 wlp1s0
link-local      *               255.255.0.0     U     1000   0        0 wlp1s0
192.168.1.0     *               255.255.255.0   U     600    0        0 wlp1s0

The driver is working or you wouldn't even see wireless networks

bcripps · Post by **bcripps** » Sat Aug 13, 2016 11:15 am

Yes, in Win 7, I connect directly to the internet via wifi. The password is stored. I am using that computer right now to write this thread.

In Mint, when I press the icon in the task bar in the lower right, I get a window with all the available hotspots, about five of them.

When I click on “Wendy's Bar” I am prompted for the password. I enter it and press connect. That seems fine but Foxfire can't find the server at Mint.

When I again click on “Wendy's” it asks me for the password allover again.

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.1.1 0.0.0.0 UG 600 0 0 wlp1s0
link-local * 255.255.0.0 U 1000 0 0 wlp1s0
192.168.1.0 * 255.255.255.0 U 600 0 0 wlp1s0

I don't get those last three lines.

Thanks again, Jeremy. Appreciate you taking the time.

Coming from left field. Question! Is there a switch in system configuration, under network manager, for airline mode that is switching off your WIFI?

bcripps · Post by **bcripps** » Sat Aug 13, 2016 12:16 pm

Thanks for the input, Tomgim5...

But I don't see “system configuration” or “network manager” listed anywhere. And a search on “Airline Mode” and “Airplane Mode” yields nothing. I know it's got to be there somewhere! Could you give an old guy a hint?

Thanks for pointing me in the right direction...
Bry

Post by **JeremyB** » Sat Aug 13, 2016 12:51 pm

After trying to connect to Wendy's Bar go into terminal and enter

Code: Select all

dmesg | tail -20

There might be an error explaining what the issue is.

I doubt it is an issue with airplane mode as it disables the wifi

Hope this helps, Jeremy.
And I'll add this: When I open “Drive Manager” a window opens up and tells me “Drivers cannot be installed. Please connect to the internet or insert the LM USB stick.”

OS tries to update the cashe from the stick but a window opens with, “Failed to download repository information.”

In “Details” I get a blurb about “Repository does not have release file. Data from such a repository can't be authenticated and therefore potentially dangerous.”

Once again, means nothing to me but thank you so much for your help.
All best,
Bry

Next time you can, don't try to connect but run

Code: Select all

iwlist scan | egrep -i 'ssid|mac|cipher'

There may be more than one access point using the Wendy's Bar name and your system may be trying to switch from one to another and if that is the case see http://askubuntu.com/a/425617/300665
