English Network/Internet

hello,

i am a newbie to opensuse so please guide my steps :slight_smile:
i have installed a wireless usb adapter, netis wf2123, with realtek 8192cu chipset.
when i want to connect to a wireless network using KNetworkManager i see all of my neighbors wireless networks but not mine. and yes my network is visible (i can see it and connect to it from my phone and laptop).
i have also new hotspot from my laptop and this is not showing either.

please help.
thank you

Perhaps it has to do with the location of your computer.

Maybe the signal is blocked by something, or there is some kind of signal interference between your router and your computer.

Try temporarily moving your computer to another area and see if you can now see the signal, or move your wireless router to another area, perhaps closer to your computer.

hi,

the computer was near the laptop and the laptop has 95-100% signal. also the other computer that i have tried to use with the same wireless usb adapter is near this one so the interference is out of the question.

thanks.

I’ve occasionally found that the KDE plasma applet doesn’t refresh itself as dynamically as I’d like, but if I run a scan manually (with appropriate wireless device name)

/usr/sbin/iwlist wlan0 scanning

the detected networks are then reflected in the applet list. (Perhaps that will work for you too.)

I have also found, if using Network Manager, click on the Network icon in the Panel/Tray, uncheck Enable wireless, then recheck. The list will refresh and your router may show up.

i have tried what you have said. i have also put the usb adapter in all the other usb ports and it refreshes the networks but mine isn’t shown.
i have also used ifup and scanned several times. The result was the same.

thank you.

Report back with

/sbin/ifconfig

so that we can see the name of the wireless device, then using the name of that device do '/usr/sbin/iwlist scanning eg

/usr/sbin/iwlist wlan0 scanning

and post the output from the scan. Please enclose the output within

...[/CO..] tags by using the '#' icon in the forum editor.

i have figured out the problem.
the router was setup to use channel 13 and apparently opensuse does not know this channel (on win/ios/android it works).
so i have changed to channel 1 and it works like a charm.

thanks for your help.
