SOLVED: Network Manager Says Wireless Unavailable

Postby DrSpaced » Sun Oct 29, 2017 11:59 pm

I am trying to get wireless working on a Linux Certified laptop running 64-bit Mint 18.2 Cinnamon in a fresh installation. I had asked for Codecs to be included during the install. The wireless interface that I am working with is an Intel Wifi Link 5100 that the laptop came with. Network Manager correctly identifies it but also shows that it is "unavailable". A USB Cisco AM10 that I plugged in is shown to be "unavailable" too. I have a wired link, so I can easily share any diagnostic output one might require. Please tell me what next steps to take.

I assume you've looked for the wifi switch? Usually it's in a place where you can reach it when the laptop is closed, so you can switch the wifi off before switching the laptop on, for example in an airplane. Sometimes they are hard to find :wink:

If your issue is solved, kindly indicate that by editing the first post in the topic, and adding [SOLVED] to the title. Thanks!

On my laptop I had to press the function+F2 keys to toggle the wifi on after I installed linux.

It came with win 7 installed and I didn't have to do anything with the wifi in windows.

I have tried what I think is the WiFi switch. It is centered horizontally between the screen and the keyboard. It has a label which resembles "(((W)))" with the inner parens smaller. Next to it is one which depicts a keyboard key with a capital W in the center. On the other side of the supposed WiFi switch is one which has a label that looks like:

Code: Select all

        |-----------
        |     -----------|
        |-----------     |
              -----------|


except that the corners are rounded and connected. I confess that I don't read pictures well, so I have no idea what the laptop maker was trying to communicate. Lastly, there is another
rectangular unlabelled key that is twice as long in the horizontal as the vertical just below the
power key. I have no idea what that is either.

What do you suggest?

Also, the diagnostic output indicated that there was a RealTec WiFi interface. Is it really true that I have three WiFi units in this laptop (counting the AM10)?

My Dell laptop came packed with a reference card explaining what all the fn+f key did.

Also that info can be found on Dell's support web site along with detailed pdf owner/user/repair manuals.

Maybe check your manufacturers web site :?:

I take from your reply that you do not read pictures any better than I do.

I did notice that the F2 key has a picture (((!))) - upside down - on it. The Fn+F2 may well control the wireless too, but I tried it and there was no effect. (The way I tried it was to press it, check the Network Manager, close Network Manager, press it again, check again the Network Manager, and so on.)

I did check the manufacturer's website. There is no support of older or even current products there, I will have to call them tomorrow.

I note that you didn't answer my question:

In any case, thank you for your insights thus far.

You have three network devices, two wireless, the one you plugged-in is Card-3, Card-2 is wired Ethernet and Card-1 is the one that the laptop came with.

Code: Select all

Card-1: Intel WiFi Link 5100 driver: iwlwifi bus-ID: 0e:00.0
Card-2: Realtek RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller
Card-3: Linksys AM10 v1 802.11n [Ralink RT3072]


One of them doesn't show as blocked, probably the Linksys AM10, so I'm befuddled why that one isn't working :?

Success!

Thanks to encouragement by WharfRat, I located the WiFi switch on this laptop. I was able to connect with no further problems.

The switch was hard to see, There was embossed ON/OFF in black plastic on the switch just below the status lights in the lower left of the keyboard. I don't see well and this escaped me before.

What those other buttons are for, I don't have a clue.

Glad to hear you had success in locating the elusive wifi switch.

I scanned a part of the reference I mentioned in an earlier post just as an fyi.

Good luck :wink:

I sent an email to the manufacturer for any laptop documentation especially the exterior swithches and indicators.
