Always thought that it is the domain name resolution problem, but also do not feel like. Today in Baidu search "ubuntu16.04 Domain name resolution slow" when inadvertently saw the
http://blog.csdn.net/ferrarifomaul/article/details/51544634 this blog link, the topic is "Ubuntu 16.04 LTS Connection Wireless Internet slow solution", just in line with my computer symptoms.
Original:
Installed Ubuntu 16.04 LTS after connecting wireless internet, found surprisingly slow. Online search for pro-test effective methods are:
1. Running at Terminal: sudo gedit/etc/modprobe.d/iwlwifi.conf
2, in the opening of this configuration file in the white space to add: Options Iwlwifi 11n_disable=1
3. Save the file and restart it. (I have succeeded)
I tried it in his way and it worked, but I was not sure how to solve it.


Then searched the next "wireless network card 11n", find the following instructions:

802.11 is the standard of wireless network connection, which is what we usually call WiFi.


Easy to use, as long as the network card plug into the computer, install the corresponding version of the driver, you can search the wireless network, connection use.



2.802.11B refers to the 11M rate standard, 802.11g refers to the 54M rate standard, 802.11n refers to the 150M rate standard.


The 802.11n transmission speed estimate will reach 540mbit/s (which requires a higher rate of transmission at the physical layer), the new standard should be 50 times times faster than 802.11b, and about 10 times times faster than 802.11g.


802.11N will also be more distant than the current wireless network, different from the model BG can only support 54M of bandwidth, the BGN can support 150M or 300M bandwidth, are backwards compatible!

802.11N is a newer network card, the highest rate seems to support 128m/seconds, but now the average wireless router up to 54m/seconds, in fact, is not used, and our telecommunications broadband generally only 3M ....


So I guess our router does not support the 11n standard, and the system always use the standard of 11n to find it to connect, not successful to try another standard, on this wasted time. Options Iwlwifi 11n_disable=1 This will disable the 11n will not have to try, once and the router on the letter.
