Hey I have a new Asus Zenbook with Intel 7265 wifi card and constantly in couple of minutes internet connection is getting very slow/not working at all. I have newest driver from Intel site lwifi. Does someone know what is not right? Here is message from dmesg:

I own and use successfully two Intel wireless devices. I have honed a few techniques in several years and thousands of forum posts.
First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.
Next, I recommend that your regulatory domain be set explicitly. Check yours:
If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:
Of course, substitute your country code if not Iceland. Set it permanently:
Use nano or kate or leafpad if you don't have the text editor gedit.
Change the last line to read:
Proofread carefully, save and close the text editor.
Next, I'd set IPv6 to Ignore in Network Manager: http://docs.fedoraproject.org/en-US/...pv6-ignore.png This example is for ethernet, but you want wireless.
Finally, I suggest that you update the firmware.
Reboot and tell us how it's working.
