Installing Ubiquiti Unifi Security Gateway

I just received my new Ubiquiti Unifi Security Gateway and here are the steps that I used to go about installing it.

Update the USG

1. Downloaded the latest firmware onto my laptop https://www.ui.com/download/unifi-switching-routing/usg
2. Plugged the USG into power and waited for it to finish booting
3. Performed a Factory Reset to ensure no hiccups
4. Attached a Laptop to LAN1 (also disabled laptop wifi)
5. Copied firmware over to USG (if on windows you can use WinSCP)
• scp UGW3.v4.4.50.5272448.tar ubnt@192.168.1.1:UGW3.v4.4.50.5272448.tar
• password: ubnt
6. SSH into the USG and run the update
• ssh ubnt@192.168.1.1
• password: ubnt
• sudo syswrapper.sh upgrade UGW3.v4.4.50.5272448.tar
• The system will the print some output and then reboot

Configure the USG

Warning 1: Despite the USG having 2 LAN ports, 1 is disabled out of the box, so you will not be able to have both a laptop and a Unifi controller plugged in at the same time without a switch or hub.

Warning 2: It seems that any change no matter how small seems to trigger a USG reboot. So you will want to have it completely configured before inserting it into your network.

Results

This allowed me to repurpose the ASUS router as a WiFi bridge to replace the Linksys E2000 which upgraded me from N300 to AC1300, which gave me a real world doubling of speed ~5MB/s to ~10MB/s.

Convert Cisco Linksys E2000 into a Wireless Bridge using dd-wrt

My recent purchase of a refurbished Asus AC66R wireless router has left my previous router, a Cisco Linksys E2000, free to become a wireless bridge to upgrade my ps3 from 2.4GHz G to 5GHz N. Here are the steps that I followed to do it.

Disclaimer: All activity you do is at your own risk. I am not liable for any damage you do to your equipment.

1. First setup my new router and ensured that the encryption used was WPA2 Personal-AES on both spectrums
2. Downloaded dd-wrt.v24-21061_NEWD-2_K2.6_mini-e2000.bin from the dd-wrt page: http://www.dd-wrt.com/site/support/router-database (search E2000)
3. Followed the flashing instructions on the wiki: http://www.dd-wrt.com/wiki/index.php/Linksys_E2000
1. Disconnected all ethernet cables and wireless clients
2. Did a 30/30/30 reset using a pen
3. Connected my laptop using an ethernet cable (also turned wireless off on my laptop)
4. Log into Linksys Web Interface Firmware Upgrade page at 192.168.1.1 using the default password (admin), went the Administration tab and then the Upgrade sub-tab
5. Wait 10 minutes until WLAN (wireless) light turns on.
6. Power cycle by unplugging E2000 for 30 secs.
7. Plug E2000 back in and wait about 5 minutes until it finishes booting.
8. Do a 30/30/30 reset on router.
9. Wait 3 minutes and log into web interface using the default user/pass (root/admin)
10. The router then made me change the password
11. You are done. There is no NEED to flash any other build.
4. I then configured the E2000 to be a wireless bridge using this wiki: http://www.dd-wrt.com/wiki/index.php/Wireless_Bridge
1. My new and old router both use the ip 192.168.1.1, so if you use a different subnet be sure to modify accordingly
2. Changed the E2000 to a static ip
• Setup Tab -> Basic Setup sub-tab -> Network Setup heading
• Local IP Address: 192.168.1.2
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.1.1
• Local DNS: 192.168.1.1
3. I also disabled the WAN port at this point
4. Hard-coded a static ip onto my laptop wired connection
1. Control Panel -> Network and Sharing Center
2. Left side -> Manage Adapter Settings
3. Right Click on your wired connection -> Properties
4. Highlight TCP/IPv4 -> Click on Properties Button
5. Use the following IP Address:
• ip: 192.168.1.100 (or a similar unused one on your network)
• subnet: 255.255.255.0
• gateway: 192.168.1.1
5. Disable the DHCP server on the E2000
6. Change the E2000 into wireless bridge mode
1. Wireless Tab -> Basic Settings Sub-Tab
• Wireless Mode: Client Bridge
• Wireless Network Mode: N-Only (5Ghz)
• Channel Width: Auto
• Wireless Network Name (SSID): type in your 5GHz network SSID
2. Wireless Tab -> Wireless Security Sub-Tab
1. Security Mode: WPA2 Personal
2. Encryption: AES
3. Password/Passkey: type in your network password

After all this I was able to successfully connect to the internet and the rest of my network. It also maxed out my 100Mbps laptop ethernet port.
