Unable to connect to a wireless network


Hello,

I have an HP ProBook 4540s with a network card (RTL8168evl/8111evl at 0xffffc9000001e000, b4:b5:2f:7). I have a dual boot system (windows 7 and Fedora 20). I have no problems using my home netowrk via wireless. However, when I try to connect to my school's wireless network with fedora, I'm not able to do so. I have no problem connecting when using Windows 7. I am able to see other networks. I tried typing in the SSID and everything but with no luck. My other classmates are able to connect to the network using linux OSs.

It is possible that your school Access Point is configured on a channel that your Wifi Card is not configured to see.
The number of channels depends on a parameter that called Regdomain, Every country has its own configuration.
Try to find out how to configure this parameter on Fedora 20.

Hi,

I believe that command from cli would be 'iwlist wlan0 scan'.

EDIT: man iwlist does show 'scanning' as an option, newer iwlist will also use 'scan'
Hope this helps.
Have fun & enjoy!

I thought they changed to scanning, but I do know there was a change.

'iwlist wlan0 scan'

Substitute "wlan0" with your wifi, might be eth1 or so. Still if you get a signal result 'icon' on the gui you could left click on that to see if any more wifi's are present. Also how did your classmates connect using linux and are they using fed20.

Fred.

Hi,

You can truncate several of the iwlist options;
Quote:
From 'man iwlist';
DESCRIPTION
Iwlist is used to display some additional information from a wireless network interface that is not displayed by iwconfig(8). The main argument is
used to select a category of information, iwlist displays in detailed form all information related to this category, including information already
shown by iwconfig(8).

PARAMETERS
scan[ning]
Give the list of Access Points and Ad-Hoc cells in range, and optionally a whole bunch of information about them (ESSID, Quality, Frequency,
Mode...). The type of information returned depends on what the card supports.
Triggering scanning is a privileged operation (root only) and normal users can only read left-over scan results. By default, the way scanning
is done (the scope of the scan) is dependant on the card and card settings.
This command take optional arguments, however most drivers will ignore those. The option essid is used to specify a scan on a specific ESSID.
The option last do not trigger a scan and read left-over scan results.

freq[uency]/channel
Give the list of available frequencies in the device and the number of defined channels. Please note that usually the driver returns the total
number of channels and only the frequencies available in the present locale, so there is no one-to-one mapping between frequencies displayed
and channel numbers.

rate/bit[rate]
List the bit-rates supported by the device.

keys/enc[ryption]
List the encryption key sizes supported and list all the encryption keys set in the device.
Notice the bracket of options in the above quote to indicate the usable option.
Hope this helps.
Have fun & enjoy!

Hey guys thanks for the quick responses. I tried iwlist (wlan0, eth0, and wlo1) scanning, I get Interface doesn't support scanning. I also tried the iwconfig (wlo1) which I believe is the interface I'm using
The message is:
IEEE 802.11bgn ESSIDff/any
Mode:Managed Access Point:Not-Associated Tx-Power=16 dBm
Retry Long limit:7 RTS thrff Fragment thrff
Power Managementff[/COLOR]

Again, thanks
