[SOLVED] Wireless connection jumps out with hidden network essid

I'm trying to setup and configure my wireless interface, and have managed to connect to the internet, but the connection seems to "jump out" after a couple of seconds and stays unstable. I.e. I can reload websites a couple of times, until it snaps back for a moment, then jumps out again.

Im using the iwlwifi-5000-ucode firmware package with my Intel PRO/Wireless AGN 5100 card, and I've configured the connection manually with wpa_supplicant, using the wext driver.

This is the output of 'iwconfig wlan0':

wlan0     IEEE 802.11abgn  ESSID:"trojanet"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:90:D0:FC:F1:09   
          Bit Rate=11 Mb/s   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=66/70  Signal level=-44 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

and 'ifconfig wlan0':

wlan0     Link encap:Ethernet  HWaddr 00:16:EA:E2:06:D0  
          inet6 addr: fe80::216:eaff:fee2:6d0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2234 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4919 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:619126 (604.6 Kb)  TX bytes:783929 (765.5 Kb)

Is this maybe an issue with the driver or firmware? Appreciate any help on this as I am very new to Arch Linux!

Re: [SOLVED] Wireless connection jumps out with hidden network essid

It might be possible your missing some microcodes that would help stabilize your connection.. I have the Intel Wifi 1000 card and I neeeded ucodes other than the one specified for my card in order to even get it to work.. figured that out by using dmesg whenver I toggled my wifi on and off using my laptops wifi switch.

Re: [SOLVED] Wireless connection jumps out with hidden network essid

My problem was a security setting in my wireless home network. I had set my router to not 'broadcast network name', which basicly hides the network name from neighbours. Now my connection is stable, and working as it should.

Before I changed the setting, when i ran 'iwlist iwlan0 scan', I noticed my network name was displayed hidden like this:

ESSID:""

I think maybe the problem was that I tried to associate my interface with the essid name 'trojanet'. Also, I noticed some difference in the 'ifconfig wlan0' output after changing the setting:

wlan0     Link encap:Ethernet  HWaddr 00:16:EA:E2:06:D0  
          inet addr:10.0.0.4  Bcast:10.0.0.255  Mask:255.255.255.0
          inet6 addr: fe80::216:eaff:fee2:6d0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1935 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1738 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1086030 (1.0 Mb)  TX bytes:223412 (218.1 Kb)

Compared to the first output, it seems I've been assigned an ip adress.

Thanks for helping
