Weird thing with home wireless network

[lighthouse]

Dear all,

I've been using nicely home wireless network with ZyXel modem.

Now my laptop just can't find our home wireless network while other people can use it very well.

The weird thing is because I can see other locked wireless networks.

The only solution is to connect to the model by cable but house owners don't like me sitting all the time in their room

Could you please help me?

Using Fedora 14 with latest yum update.

I have all kmod and akmod wireless drivers installed. I was able to use wireless few weeks before, but now something completely wrong is going on. And the problem happened even considering the fact that I did not make yum update when it occurred. Now I did, but no change.

So are you saying that you used this network, but now you can't even see it in NetworkManager?
What changed after last time you could see home network? Did you install any update or changed configuration? Anything?
Could it be that you homeowners changed the frequency of router from 2.4 to 5.0 GHz and your laptop works only for 2.4?

100% true, the good thing that I see other networks - this means my wireless card is working and the sign on the laptop is lightning with white colour as it should.

What changed after last time you could see home network? Did you install any update or changed configuration? Anything?

Nothing changed, I only connected to through wired and did yum update, but the problem appeared before that.
No, I did not change anything, I was a complete user of my laptop.

I have just modified my previous post. Not sure if you noticed it.
So:
Could it be that you homeowners changed the frequency of router from 2.4 to 5.0 GHz and your laptop works only for 2.4?

[lighthouse]

I don't think so. Anyway I can visit http://192.168.1.1 and configure modem as I want. It is set inside now: Auto Channel Selection.

[drewkenjo]

I believe you are talking about different thing. There are 11 channels in the band between 2.4GHz and 2.5GHz. But there is also another band 5.0GHz. Not all laptops and routers can use this another band. You need to look over all menus in router. May be someone changed this band. You also can read router documentation to check if it supports 5GHz. Can you give your router model?

[lighthouse]

Yes, my modem is ZyXel NBG-417N . As I see in configuration inside by talking to its interface through 192.168.1.1
It can offer only 2-2.5 range of Mhz, no 5.

[drewkenjo]

Well, then I don't know) Can you scan wireless network not from NetworkManager but using "iwlist wlan0 scan"? Then redirect output to text file and see if you can find your network there. You may need to change wlan0 for your interface.

Dear,

I changed frequency from auto to 2.* and it works. Have no idea why

Let's see if house owners will be able to searf the web

Thank you, your suggestion about changing the chanell had helped!

[drewkenjo]

Glad I could help.

The wireless routers from 2 years ago that said dual band were often only capable of running on one band or the other but not both. Modern routers say simultaneous dual band and are much better (you can set up a different ssid on each band)
