we installed 3 R600's unleashed in a community room that needs to support 400 users.
The backbone is all aps joined to there own 2500 series Aruba POE switch. Directly out a 100Mbit fibre connection.
Basically becomes unusable after 60 users connect, and were not even hitting it hard this is just browsing web pages.
Ruckus has had me reset them to factory 2 times and had a few calls but they seem to be spinning their wheels and we have never used these devices before.
We use R600 unleashed APs for dedicated wireless requirements during corporate events and have never seen a problem like this before. However saying this, I wouldn't recommend that you ran 400 users over just 3 APs. Although they are within scope, their throughput would be subject to a bottleneck experience.
I assume that they are all connected to the same VLAN and route traffic through a shared gateway? Are the APs connected at 1Gbps from the switch? Have you added a second LAG link per AP? Is there any rate limiting from the switches or APs?
What are your channels set to?
Do you have any QoS in place i.e rate limiting in place?
"The backbone is all aps joined to there own 2500 series Aruba POE switch. Directly out a 100Mbit fibre connection." : So you have 3 PoE switches and each AP is connected to a different switch? How are those switches connecting to your core router? Are you daisy chaining them?
3 aps all plugged directly into 1 Aruba 2500 series POE with no QOS running. This switch is only for this wireless setup nothing else is plugged into it.
The switch uses a secondary interface on my sonicwall router (NSA 250 M) to get out to the internet while staying completely separate from my corporate network.
the corporate network is a municipal office and hockey rink with 20-60 users during business hours.
the channels look to be random on each radio not sure where that is set on these but they are all different.
In your Unleashed dashboard go to Access Points>Select AP1>Edit>Radio B/G/N (2.4G)>Override Channel: 1 / Radio A/N/AC (5G)>Override Channel: 157. Ok/Save.
AP2, follow the same procedure but for 2.4G choose channel 6 and for 5G choose channel 161.
AP3, follow the same procedure but for 2.4G choose channel 11 and for 5G choose channel 165.
Since you have no QoS in place and most of your users are doing simple web browsing, I would rate limit them to 1Mbps up/down. You can do this at the router level or WLAN level, and since we are on the topic of Unleashed: WLAN>Advanced Options>Access Control>Rate Limit>Uplink: 1Mbps Downlink: 1Mbps.
Each AP is on its own VLAN correct? What is the subnet size? When the network becomes unusable, are clients spread out across the 3 AP's or is one being overloaded?
I'll set the channels as suggested
interestingly enough support told me you cant limit client speed with unleashed you need a controller for that. so thank you!
1 vlan for the whole wireless network all and the default vlan since its segregated physically from the rest of the network i seen no need for VLANS
I may also recommend turning load balancing on, which will help spread clients between your access points: Go to Wi-Fi Networks > Edit > Show advanced options > Radio Control, and select the check box next to Load Balancing. Experiment with this option enabled and adjust accordingly.
I will definetly experiment with these options
Simple WPA2/PSK may offer best performance over a Guest Access/HotSpot or 802.1x network, when roaming
is involved. No benefit for R600 two Eth port to same switch (Link Aggregation), only 802.11ac Wave2 APs (R710,
But can you see how much of your 100mb WAN pipe is in use? It may be the bottleneck for Internet browsing, as
I understand the issue still persists. Since we are not able to troubleshoot the issue when the issue occurs live, kindly execute the below commands from the Master APs CLI. The below commands will encourage the clients to join with a higher data rate to the WiFi.
ruckus(config)# wlan <WLAN Name>
ruckus(Config-wlan)# no qos directed-multicast ruckus(Config-wlan)# qos directed-threshold 0 ruckus(Config-wlan)# end
Please keep me posted on when the next event is scheduled. It is important for us to see the issue live in order to identify what is causing the issue. From the screenshots taken at the time of the event shows that all the clients were connected with good speeds to the WLAN.
