Hey Guys,

Maybe you can give me some hints on my very very strange wifi-problem.

Since a few days i’m no longer able to connect to my mikrotik-wifi with my dell notebook. All other devices we have in our apartment works well (iPhone, iPad …)

I always get some very strange error messages in logging when i try to connect with my notebook like this:

So i don’t think that my wireless card in my notebook does have some kind of error because the wifi-connection works on every other place (working company, cafes, mc donalds …)

in an other post i found at google there was an hint to reduce the tx-power (maybe to near to the ap - my router is under my working table so the notebook is directly above - maybe 30-40cm distant) but that also does not help anything.

as an additional information: my notebook is equipped with an intel centrino advanced-n 6205 chipset.

So actually i’m at one’s wits’ end so maybe you have any hints or in the best case some solutions for me :wink:

kind Regards
Florian

when you see in the registration table when you connect. as it seems you are connected for some time. Check signal levels.

Hey,

First: Thanks for reply.

I’m not shure if i understood this correctly. You mean to check signal levels exactly at this moment when my notebook is connected?

Kind Regards

when the notebook is connected i see following signal strengh in screenshot (attachment).

Hey Guys,

So upgrade to 6.5 solved the problem without changing anything at the config.

Kind regards
