802.11ac has made great strides in improving Wi-Fi performance by using a wider channel, a more efficient modulation mode (by transmitting data in RF waves), and multi-user connections (so-called multi-user MIMO. In fact, this kind of progress will come in a wave in the future.
However, the new 2nd wave chip is different from the 1st wave device (please read the hardware upgrade)
Remember that not all 802.11ac access points are the same. Many access points using the
Recently, the DNS redirection problem was involved when I modified the software for the customer. So I studied the DNS of the DSL ROUTER in the broadcom solution and implemented DNS processing in opensuSE.I. Introduction1. The broadcom scheme dsl router implements DNS proxy through DNSmasq. DNSmasq is a lightweight and easy-to-use DNS service tool. It can be used for IP address translation during Intranet a

1, first determine the Broadcom type network card:
/sbin/lspci | grep Broadcom
2. Need to get the network card driver down, and then compile their own, so you must first Ann this thing:
Yum Install kernel-headers kernel-devel gcc
3. View the number of system bits (if you know you can skip this step):
Getconf Long_bit
