1 Ruckus Wireless access point set up from an Audio Everywhere streaming perspec;ve Lance Glasser 6 June 2015

2 Overview Ruckus access points are a very good choice for Audio Everywhere systems. Over the next few pages we go over the set up material that has worked best for us. Audio Everywhere is an authorized Ruckus reseller. We tend to use the Ruckus AP s (access points) in stand alone mode rather than with their zone director hardware. When talking directly with Ruckus, you can tell them that the applica;on is like one way VoIP.

3 DON T Don t Use TKIP encryp;on (severe limit on number of phones) Don t use Mesh networking (handles fewer phones with more latency). If you have to bridge to someone else s WAN, use an external device like a WAN over Wi- Fi system from Cradlepoint or Pepwave Don t Try to do a so[ware upgrade of the AP remotely. Instead download the file and do it locally.

4 Models R300, the entry level system we use most o[en. Can handle clients (i.e., smart phones) R600, a high- end robust system that can handle clients, or more. 500 clients might be possible. R700, R710, etc., top of the line.

5 Set- up There are two levels at which one can a`ack the setup. The first is using the simple GUI screens that one sees with the login just discussed. The second level is to remotely log into the AP using ssh and use the Ruckus Command Line Interface (CLI). This is deep and dangerous stuff and you should only venture there if you are a skilled IT professional.

6 Simple setup Turn on the 2.4 and 5 GHz radios and set the SSIDs (could be the same) Set the encryp;on method to DISABLED to get the highest number of clients served as possible Set the 5 GHz bandwidth to 20 MHz See the next screens for examples Don t forget to UPDATE SETTINGS

9 5 GHz channel width

10 5 GHz radio

12 Sefng up the AP If it is not the first ;me someone set up this AP you may need to reset the AP with a paper clip. See the Ruckus instruc;ons. The default IP address is Set up a stand- alone computer with a fixed IP address, e.g., IP , mask , router Open your browser on the notebook computer and type h2ps:// Log in User: super Password: sp-admin

13 AP setup challenges Depending on what browser you are using, it will check the cer;ficates on the Ruckus AP. If you are edi;ng more than one AP with the same laptop, you may find that the laptop refuses to connect to the second AP because it no;ces that the cer;ficate has changed for the same IP address. Safari is par;cularly problema;c here. Use Firefox on the Mac instead. You will have to tell Firefox that you know what you are doing and that it should connect.

14 Deep setup using ssh and the Command Line Interface Open a terminal on your connected laptop and ssh super@ login: super password: sp- admin rkscli: set band- steering wlan0 5 rkscli: set bss- minrate wlan rkscli: set channelfly wlan0 mtbc 420 Where rkscli is the prompt and wlan0 is the device name. See next page for that these incanta;ons mean Ruckus has a command line interface (CLI) guide they can send you

15 Meaning of Command Line Interface code Band steering This encourages 5 GHz capable phones to use the 5 GHz band, which is generally less crowded but not as good at going through walls. [this command is not on the R600] bss min- rate Sets the minimum data rate in kbps at which an AP will associate with a client. Don t want this to be too low for good quality streaming. Set to 12 Mbps. Channel Fly Channel Fly is the AP feature where they switch channel frequencies in search of a be`er signal/noise ra;o. But switching too o[en is difficult for Android phones, which may not follow the hops, and can also be some;mes heard in the audio. This number tells how many minutes to which to limit the switching ;me. Set minimum to about 7 hours. Alterna;vely you can let Channel Fly do its work for a while and then turn it off.

16 Gefng around host checking If you want to ssh into different APs from the same laptop, you may have to set the laptop configura;on file to not do strict host checking. This is very dangerous. Or you can add each new Ruckus to the knownhosts list. For the first, edit (or create) the file and add the line and save. And be careful! ~/.ssh/config StrictHostKeyChecking no

17 Ruckus AP Standalone Configura;on for isolated subnets

18 A Separate Router is Usually Best Ruckus APs - NOT routers by default BUT can be routers + DHCP servers in standalone mode

19 Ruckus APs are bridges You need to be familiar with basic IP networking A bridge (or a switch) operates at network layer 2 Ruckus APs are bridges by default Everything connected to a bridge/switch must be on the same IP subnet to communicate IP (Internet Protocol) operates at network Layer 3 Routers route traffic between subnets The Internet will be on the uplink or WAN side The Venue network will be on the downlink or LAN side Routers may offer NAT (Network Address transla;on) NAT hides the LAN IP addresses behind the router WAN IP

20 Venue Router behavior (typical) Routers have mul;ple IP addresses The venue router will get an IP address by DHCP from the ISP on its WAN (uplink) port The venue router will have a different IP address on the venue network The venue router will hand out DHCP addresses to the venue devices on LAN port(s) The venue router will NAT internal addresses on the Internet Internet traffic would only see the WAN/external IP; the router will keep track of which internal IP(s) gets reply traffic

21 Ruckus AP in standalone mode No Zone Director on the network Or ZD can be configured to NOT automa;cally accept all APs AP in factory default state Fresh out of box or factory reset Default AP sefngs are IP address: Username: super Password: sp- admin NB all this is on the underside label DO NOT plug the AP into the uplink before configuring it or it will get a different address from the ISP DHCP server

22 Standalone AP o Configuration o Menu items show AP is in standalone mode

23 Configura;on - > Internet R300 has one port. Will need to convert to LAN o You should not have to change anything here o Wired ports are WAN ports o 7372 and 7982 both have two ports o Both ports default as WAN ports o One can be converted to a LAN port (And probably should be; see following slides) Once fully configured, you could check the ISP assigned address here, by clicking static IP and then returning to DHCP

24 Configura;on - > Local Subnets o Click on Local Subnet o Choose Enabled o Example Settings: o Local IP: (router s internal IP) o Subnet mask: o DHCP: enabled o Starting address: o Maximum users: 250 o Access VLAN: 10

25 Rou;ng port assignments There are now two subnets on the AP WAN/Internet address to be assigned by DHCP LAN/local - addresses configured by you Local Subnet 1 In our example, DHCP server enabled on that subnet Now the subnets must be assigned to ports The default sefng is EVERY port is on the Internet subnet (bridge mode) WLANs (SSIDs) are logical ports In other words, we have to tell the ports which side of the router they are on in or out? WAN or LAN?

26 Configura;on - > Ethernet ports o One port can be a LAN port: o change packet forward to Local Subnet NAT and Route to WAN o For Local Subnet change to Local Subnet 1 o Do this last since it will change the IP address

27 Configura;on - > Ethernet ports, cont. Both the 7982 and the 7372, have two Ethernet ports One 10/100 One 10/100/1000 PoE The R300 has one Ethernet port You probably do not have a gigabit Internet link Choose the10/100 port to serve as the bridge to WAN or Internet link If you change the port you are plugged into, you will lose connec;on That s OK you will need to change IP to match local subnet 1 and reconnect You could get more elaborate about subnet assignments and use all 4 local subnets. Only do this if you understand what you are doing and have a good reason to do so

28 Configura;on - > WLAN ports o Configure WLANs as before, with additions o Packet Forward choose: o local Subnet NAT and Route To WAN o Local Subnet choose: o Local Subnet 1 o Repeat for all WLANs/ SSIDs

29 You now have a Ruckus router AP You have a LAN port for any wired devices If you have more than one, you will also need a switch Your SSIDs are on the LAN side of the router The AP will assign DHCP addresses on the LAN The AP will NAT all addresses on the Internet The LAN port goes to the Venue Server LG
