There is no WiFi listed to connect

THE PHANTOM · 12-11-2016, 07:34 AM

Hello here,

I have problem on Wifi, HP pro book with Debian Linux, i have internet with wired but there are no WiFi list to connect. I have done this : https://www.linux.com/answers/how-do...an-see-my-wifi and what help got from Debian forum but problem is not solved.

My WiFi adapter is that:

Code:

mesg | grep firmware

[   20.574964] r8169 0000:01:00.0: firmware: direct-loading firmware rtl_nic/rtl8168g-3.fw

Hope i will get support here too. Thanks in advanced.

Most of what you show us is related to your video card, which is unlikely to be related to your problem.

The RealTek WIFI device appears to be detected and a driver loading.

I found this discussion of problems (and a solution) with some of the drivers, but this may or may NOT apply to your case.

Now, just because a device is detected and a driver loaded does not mean it is turned on or configured. It is unclear what you might have done (or not done) to detect WIFI SSID broadcasts and configure your WIFI. There are multiple tools for this (especially in Debian) so I am not sure I can make assumptions here. Are you using Network Manager, and have you ALL of it installed? If you are not using Network Manager, what are you using to set up networking?

We need to know what you have done, what you used to do it, and what exactly worked and did not work. Without that we are flying in the dark.

Thanks for repply back,

My Wireless adapter is:

Code:

lspci -nn | grep Network
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]

I have done: https://www.linux.com/answers/how-do...an-see-my-wifi

https://packages.debian.org/search?k...ssie-backports

i also use that codes:

Code:

ifup wlan0

Code:

auto wlan0
iface wlan0 inet dhcp

I have Network manager and there is only wire connection detected, no SSD list.

THE PHANTOM · 12-11-2016, 11:08 AM

That is ifconfig output wlan0:

Code:

wlan0     Link encap:Ethernet  HWaddr 10:08:b1:48:fc:29  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

That looks like a properly detected WIFI NIC that is not connected or configured. Next is to make sure your radio is on and there is a WIFI network to detect.

If someone else would like to chime in: I use mostly servers with NetworkManager uninstalled and using wire and no direct WIFI. I can make all of my laptops work with WIFI fine (with or without MN), but since I have not run into the OPs problem, someone who HAS may be the more appropriate responder.

Yes it is on. I can connect on it with mobile and other devices too.

does that laptop have a button to turn on and off your device? if yes, then double check it, sometimes the kernel shuts if off. ( it has with me) ...
for this

Code:

 Realtek Semiconductor

it is a widely used device, so I am assuming Debian should have seen it and installed the proper drivers for it.

Unplug your cat first then give it a go.
did you try this?

Code:

ifconfig wlan0 up
iwlist wlan0 scan

to bring up your card, then scan for connections.

in root, of course. or sudo

I do not mean your WIFI router or hotpoint, I mean the radio on your latptop. Can you check that it is turned on?

I assume these are entries at /etc/network/interfaces. Delete those and let NetworkManager handle your wireless. The reboot

Yes it has it and it is on.

I did that code with cat cable connected:

Code:

ifconfig wlan0 up
iwlist wlan0 scan

but there was no scan results. i will try it again.

I've personally never had the luxury of cable Internet, and wifi at the same time. But if I was in this situation, I'd yank the cable first so that the only means the system had to look for a connection is by wifi.

I too am wondering why you do not have NetworkManager set up to help you in this situation instead.

BW-userx · 12-12-2016, 06:46 AM

try using rfkill,

Code:

rfkill list all # so you know what you are starting with.

rfkill unblock all # to unblock everything.

rfkill list all # to check your results

it should look something like this when you are done. No is the word you are looking for. Especially on your wifi.

Code:

userx@voided1.what~>> rfkill list all
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hp-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no

then try bringing up your wifi.

THE PHANTOM · 12-12-2016, 12:16 PM

So results of that codes was:

Code:

ifconfig wlan0 up
iwlist wlan0 scan

i tried it after i removed cable,

ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill
iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Network is down

I am newbie on Debian, how to set up it? should i first install NetworkManager?

that means it will not bring up your wifi card.
read my post #12

then install rfkill if is it not installed, then fix that first.
