Q: Macbook wifi problems, connection dropped every 5-10 minutes...

I have a problem with my wifi connection: it is down in every 5-10 minutes, when i'm browsing the internet. I have a Macbook late 2011 with Yosemite. I don't know, when all this started, because i installed Yosemite and bought a new router at the same time (2014 november). When I installed my new router (Airport Extreme 5th), i turned off the wifi on the ISP's router, and extended the new network with my old Airport Express on the upper floor in my house.

 

The problem is interesting, because when i stream some music or online radio, the stream won't stop, i can hear the music, but safari can't load websites (the blue "loading indicator line" stops at around 10-20%).

 

I have tons of lines in the console app, but can't understand them, i am not an expert in this field

 

Do you have any idea, what can be wrong with my wifi network and/or macbook?

 

Here is some lines from console, this afternoon:

    Hi tzombor,

     

    I apologize, I'm a bit unclear on your exact configuration, but if you are streaming music to your Airport Express, you are currently connected to the Express's signal, the Express is extending the Extreme's network (which is connected to the modem), and the wifi issues you are having are affecting your internet connection but not your music streaming, the issue may be between your Express and your Extreme, not between your computer and the WiFi network. You may want try narrowing this down by temporarily unplugging your Express and connecting to your Extreme's Wifi signal, then seeing if the issue persists. You may also find the information and steps outlined in the following article helpful:

    Sorry brenden dv, but you guys need to stop referring folks to outdated Apple Support articles. The one you reference still points to methods that are using the older v5.x AirPort Utility that will NOT run on the OP's computer. Please get these articles up to date to work with v6.x. Thx!

    Sorry, i can't explain myself perfectly in english, it is my third language

    I used a wrong word, i am not streaming the music to airport express, just listening live radio on my macbook (spotify or local radio from safari directly), and it is not affected by this behavior. So if my wifi drops, the "established connection to radio service" still works. But to load any webpage, i have to turn off and on my wifi (and at this point the radio stops).

     

    I have many console events like this:

    My setup is cable modem (from ISP) (- ethernet -) airport extreme 5th gen (- wireless -) airport express

     

    Yesterday i changed the default DNS servers in system preferences > network > wifi > advanced > dns to google servers (8.8.8.8 and 8.8.4.4), now it is maybe better, but i have to examine it further....

     

    I will try your suggestion, and connect to airport extreme, disabling the express.

     

    Thanks a lot!

    fix a DNS on your router, fix the google DNS 8.8.8.8 and 8.8.4.4, see too your security configuration, must be WPA2-PSK / AES, try to put your SSID without spaces, or special caracteres, also put your canal of operation on 6 (fixed)

    Apple replaced mDNSResponder with discoveryd, which among other things, attempts to resolve DNS on the local network. The numerous discoveryd error messages that you are seeing are currently an unresolved issue with this new service in Yosemite.

    Thank you for the suggestions! My security configuration is WPA2 - Personal, i changed the SSID (now without space), and set the channel to fix.

     

    But how can i fix DNS on my router? Should i use airport utility, and fill in the lines on the internet tab?

    Now there is a lightgray dns from my ISP (84.2.46.1), but on my mac > system preferences > network > wifi > advanced > dns tab i changed this to google DNS (8.8.8.8 and 8.8.4.4). Should i fix the same DNS both on my mac and in the airport utility?

     

    Another interesting thing, that i noticed today: when i am using airport utility, and the software is in foreground, i can see the "green dots" before my airport extreme and airport express, but sometimes they change to orange triangle (showing that something is wrong) for a second, than everything is back to normal again (green lights). At this moment 2 new lines show up in console app:
