ASUS PCE-AC55BT: Yes, It's Supported on CentOS 7 Linux

My Search for a PCI-E 802.11ac Adapter for Linux

I recently relocated (and rebuilt) an older CentOS 7 Minimal machine that I sometimes use to hack things together.  As the area that I moved the computer to did not have an Ethernet drop, I needed to get an inexpensive wireless adapter. 

If you are looking for a PCI-E (internal) 802.11ac adapter for use under CentOS 7.x the ASUS PCE-AC55BT is a good choice.  And based on my results, it's probably also a good choice for other Linux operating systems like Ubuntu.  I bought the adapter ($30 on Amazon) without knowing if it would actually be supported under Linux--there were conflicting comments at Amazon and in Google searches.  So, I took a chance.




The machine I am using has an Intel B85 chipset and full-size PCIE slots.  Some people are not aware that it is possible to put a small form factor PCI-e into a full-sized socket (you can).  I seated the card, and booted the machine.

It's an Intel Dual Band Wireless AC 8260


I was delighted to find that it is actually an Intel chipset (iwlwifi) which is supported on CentOS.  The installer just identified it, asked me to choose the network, and lastly enter the network key.  And for me this meant it was not necessary to do the install with the Ethernet connected (I installed from a bootable USB containing the minimal iso).

The speeds seem very good, and the range is much better than the popular TP-Link TL-WN722N 802.11n High gain USB Dongle that a pentester friend lent me to try.  Pentesters like the TP-Link  because the adapter will go into monitor mode, it has the rock solid Athereos chipset (Atheros AR9002U), and it has a detachable antenna.  The TP-LINK adapter is widely supported by most Linux distributions and works well under Kali.

How to Kill Japanese Stilt Grass [SOLVED]

A Plan for Japanese Stilt Grass Last year we put in a new lawn and to keep the costs reasonable we used seed instead of sod. We did this knowing that in the spring the weeds would return and we would need a method to deal with them.  So, we hired a very prominent and expensive grounds maintenance company to solve the problem.  We selected this vendor because we believed they had expertise where other firms did not.  In the end it turns out you don't always get what you pay for as they have only one maintenance program, regardless of the local conditions in your lawn.  Sadly their program did nothing for the Japanese srtilt grass.  In the end, our new beautiful lawn was again taken over by this invasive weed in the late spring and summer months leaving the problem to me (the computer guy) to solve. Japanese Stilt Grass, What is it?  According to the National Park Service , "Japanese Stiltgrass [Microstegium Vimineum] was introduced into the Uni...
