Configuring PPPoE Server on TP-LINK Router     Step 1 :   Access the router’s management webpage, go to  Services->PPPoE Server .     Step 2 :  Enable  PPPoE Server , enter”8.8.8.8” for DNS Server in this example. Step 3 :  Look for  Authentication , here we selected  Local . Step 4 :  Look for  Auth Protocol , there are PAP, CHAP, MS-CHAP, MS-CHAP v2, we picked them all in this example. Step 5 :  Click on  Save . NOTE  ：  If Dial-up Access Only is enabled, only the dial-in users can access the Internet; If PPPoE User Isolation is enabled, the dial-in users will be unable to communicate with each other. Step 6 :  Go to  IP Address Pool , enter  “test”  for Pool Name and  ”172.31.10.10-172.31.10.20”  IP Address Range, and then click on  Add. NOTE:  IP Address pool must be different range from LAN IP address range  . Step 7 :...

Definition : The Access Point is connected to another device via Ethernet cord and acts as an adapter to send/receive the wireless signal from your wireless network.   Step 1 Connect your computer to TL-WA501G/TL-WA601G, and then log into the Webbased Utility by entering the IP address  192.168.1.1  into Web Browser.   If you cannot log into the Web-based Utility, please click  here  and follow the instruction for a try.   Step 2 Change the LAN IP address of the access point (TL-WA501G/TL-WA601G) to avoid IP conflict if necessary. Please refer to  FAQ_173  for some detailed information. After changing the IP address of your access point, you need to re-log into it by using the new IP address.   Step 3 Configure the wireless mode to Client and connect to the wireless network. 1. Click  Wireless  ->  Wireless Mode  on the left, select Client. Note : If the wireless router or Ac...

TL-WA501G and TL-WA601G can be configured as a repeater. The repeater extends the range of the wireless network by relaying the wireless signal of the remote Access Point or Wireless Router. NOTE:  In the following sections, TL-WA501G/TL-WA601G is represented as “ REPEATER ”, and the wireless device to be repeated is represented as “ main AP ”. To configure the access point as a wireless repeater, please connect your computer to the REPEATER’s LAN port via an Ethernet cable (wireless connection isn’t recommended to use for configuration). Then you need to perform five procedures: Assign a static IP address for your computer. Change the REPEATER’s IP address to fit your main AP’s network. Change your computer’s IP address to fit your main AP’s network. Configure repeater mode on the REPEATER. Wireless Security settings. NOTE:  Procedure  2  and  3  are required because we need make sure that both the computer and the REPEATER are in t...

Java Home Directory Fail Issue on Ubuntu – RESOLVED For those of you who’re building your Ubuntu from scratch or even if you did like me and install UniFi on an AirVision NVR, , you might or might not get this after installing UniFi Controller *Setting Java Home….fail If that do happen, this might be because since the new Ubuntu, the name of the Java homedir changed according to the CPU architecture used and UniFi is using a hard-coded variable for the Java path in its startup script for some reason. You should change the homedir by editing the init script. (We won’t get into much detail about what is init) 1. Open the init script sudo nano /etc/init.d/unifi 2. Scroll down with your arrow key, look for a variable called JAVA_HOME=/usr/lib/jvm/java-6-openjdk 3. Add your instance architecture type after that string. For example, I’m using amd64bit in my instance, the string should become JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64 DO NOT touch anything else. 4. After the ...

I have always been a big fan of the  Ubiquiti  AirVision-2 software and especially the  AirVision-C NVR .  I have an installation at my office, my home and my cabin in Colorado.   Many of you have seen the images and video I have captured of the huge Elk that hang out at our cabin in Estes Park.  Today, I went to check on our home in Texas and I was greeted by this: “Unsupported Firmware” simply means the version of firmware running on the cameras is no longer compatible with AirVision.  In my case this happened automatically because I had the settings configured to automatically check for firmware updates and install them. When Ubiquiti introduced the UniFi cameras, they also released UniFi Video, not compatible with airVision firmwares.  Apparently, there is no mechanism in place to prevent the upgrade to the UniFi Video software so the cameras upgraded and thereby broke my airVision installation.  Of course, I have the auto-upgra...

There’s a million ways to do this on the wiki and the web but none of them fit my particular application.  Let me explain: 1.  The weak point in my network was an AirFiber 24 upstream from the tower I am connected to wirelessly.  This is the link that goes down in heavy rain causing an outage at our office to PROVIDER1.  We have a backup connection through a second provider that is slower but being 5GHz doesn’t drop in the rain, PROVIDER2. The network is like this: [MikroTik CCR1036-12G-4S] —[RBSXT]—[RBOmniTikU-5HnD[—[AF24]—[PROVIDER1] —[RBSXT]—[PROVIDER2] 2. Simple floating static routes with check gateway doesn’t help because on PROVIDER1 we never drop our 5GHz connection to the tower, it’s the upstream link that fails. 3. I tried recursive routes and it works but the failover was still lacking and seemed sporadic at best. 4. When failover did occur, the VOIP PBX would hold the connection open through the dead provider and some phones in the off...
