NetworkManager cannot see a network

[ekuleana]

First of all, let me admit that I'm new to this. I would appreciate some guidance in how to solve this problem.

Fedora 17 seemed to work out of the box for my Thinkpad x220. I had no problems connecting to wifi networks via the Intel 6205 on the laptop. When I added another wifi router to the network "HSLauSys", that seemed to work fine too. Then, suddenly, NetworkManager and nmcli can not see the new network. iwlist scan also does not show it. However, if I use kismet, I can see the new network SSID. Windows 8 (my laptop is set up as a dual boot system) finds the new router with no problems. And all this time, the other wifi networks can be seen by NetworkManager et al, as normal. I noticed this in the /var/log/messages:

Does this mean that something is happening to avahi?

I seem to recall asking NetworkManager to forget HSLauSys, figuring that I can add it later. Could that have broken something?

Can anyone guide me to a solution? Any suggestions to help me figure out what tree to bark at?

maybe you can see more info if you use iwscan from a command line.

[ekuleana]

By iwscan, I assume you mean iwlist as in:

iwlist wlan0 scanning

That command gives a list of networks, but does not list the network I am trying to find. Thanks for the suggestion.

The missing network isn't a 5ghz network by any chance? I just recently got a dual-band wifi router but haven't used the 5ghz wifi with Fedora yet. Maybe there's something in the wifi drivers that need adjusting. Just a wild guess.

Do you get any output by:

su
ifconfig wlan0 up
iw wlan0 scan | grep SSID

[ekuleana]

Doug, not a 5ghz network.

Sea, output from your commands:

[root-~] ifconfig wlan0 up
[root-~] iw wlan0 scan | grep SSID
SSID: HSLauInternet
SSID: HSLauNet 136
[root-~]

The network I am looking for (and can see using Windows) is called HSLauSys.

I had to solve this by changing the SSID of the wireless network. NetworkManager could see the newly named network and worked normally.
