Problems with DNS caching [SOLVED]
« on: April 26, 2012, 12:13:03 PM »
Hi friends,

I have problems with the wifi connection in my laptop, sometimes disconnect.
This is not problem of PCLOS, maybe a neighbor with a radio emission at 2,4Ghz (a baby one...), or too much connections in the area... I don't know well :(

Thinking that maybe could help at the problem I was trying to do the DNS caching, but the wifi I is not working.

I followed the tutorial http://pclinuxoshelp.com/index.php/DNS_caching step by step, and revised many times the configuration but the wifi doesn't work and get a error when try to restart the wlan0 connection: error for wireless request "Set Encode" (8B2A)

I had fear and uninstalled and reconfigured everything... Now I have Internet, but sometimes disconnect....

Why I get this error?

Any advice?


Thanks from Spain.

Have you tried using a different WIFI channel on the router?

That would be the first thing to try .......  pick a channel not close to the existing one ..

If your neighbor has the same channel it would not make yours disconnect, it might be slower speed wish I checked my wireless system and changed my channel. This is at times the driver used for a wireless adopter. when I used PClinuxos in the past a few drivers for my wireless back than did the same thing. I never fixed it.

The card in your laptop is most likely a Broadcom they always give Linux trouble.

Yes Just18, I did, I tried many channels and the problem persist. Also a technician from the ADSL company went at home, changed my router and said me that he had not solution for this problem, and could be a neighbor...

The problem is the same with other distros, sometimes I run Crunchbang...  - but PCLOS LXDE is my main distro :) -

Aleph,
           did the technician try a different laptop to connect to your router?  or have you tried different Laptops?

Does it happen if you use your laptop when closer to the router?

If something is blocking your signal sometimes, is it possible to reposition the router so it is closer to where you normally use your PC?

No, it happens in any place.

It is closer to my ESI nEar 08 Active Studio Monitor. But normally they are off.

Can you - temporarily - move the router about 1 metre or more so it is clear of other devices?

Then try it and see if it still drops out ....

Try changing the channel that you router is set to. By default most router are set to channel 6  Try changing it to channel 2 or 11

Sorry changing channels did not work.  It is possible if you live in an urban area that the entire spectrum is just too congested. 

If your wireless router allows it, try setting the power level below 100% (to 75 or 50), and change the beacon internal to a value above 100ms.  See if that helps.

:D  I was next going to suggest checking the power output (if possible) of the router .....  but as an aside could you explain why you suggest reducing the power output? It appears counter intuitive - if some other signal is interfering. Thanks.

There is not too much space in my Studio... :( but this morning I moved the router below my table, I'm going to watch.

Is the router connected to the internet via an ADSL telephone line or using a USB stick with SIM card?

If a USB stick is being used, then the problem might be the connection to the service provider, and not a problem with router or PC.

What may help in that case is to use an USB extension cable to locate the USB receiver to a spot which gives a better reception.

That's good ......  it takes another possibility out of the mix  ;)

It will be interesting to hear if repositioning the router has any effect.

To move the router doesn't work    :'(

I lost the connection again, looks connected but I can't navigate, after turn off-on the router I can navigate again.
