Ubuntu Ubuntu 16.04 lts Connection Wireless internet fried chicken slow problem!!!

With VMware installed Ubuntu 16.04 LTS after connecting wireless internet, found surprisingly slow.

Decisive feeling there is a problem, immediately look for Niang, indeed there is a problem!!!

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, add an empty space: Options Iwlwifi 11n_disable=1
3. Save the file and restart it. (I have succeeded)

Later searched the "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.
