hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action. Okay, this time your dad is going to write a tutorial WLAN Optimization with Ruijie Cloud. This lesson primarily covered the basic theory of wireless network optimization and how to use the one-click optimization feature on the Cloud Pro platform.
Since the wireless network relies on high-frequency radio waves for data transmission, factors such as transmission distance, channel planning, and interference can significantly impact the quality of the wireless signal and may even cause network failures. Typical issues in wireless networks include:
*Weak signal: Blind spots, AP offline, Connect to APs slowly, cannot Connect to AP *Internet access jitter: Broadcast message flooding, AP interferes strongly with each other, AP performance insufficient *Poor roaming experience: remote association(frequently connecting to distant APs), Roaming viscosity (fail to switch to a strong signal)
In WLANs, the surrounding environment affects the running of APs. When the channels of two neighboring APs overlap, the signals of an AP will be interfered with if the power of another AP is too high. To ensure user experience, conduct channel optimization to reduce air interface interference. The Power parameter controls the power for transmitting data frames and is used to optimize the transmission rate and control the interference scope. While maintaining the original throughput, decrease the local power to reduce interference on neighboring APs.
Wi-Fi Optimization is an intelligent and automatic RF optimization scheme tailored for complicated scenarios with multiple APs.
After Wi-Fi Optimization collects spatial information, including SSID, channel, signal strength and client status, it analyses information through the intelligent algorithm to provide the optimal network solution (channel and power planning for each AP), and automatically adjusts the configuration of APs in the network.
*Wi-Fi Optimization function entry: Project > AI Networking > AI Optimization *The user does not need any additional configuration except click Optimize Now *APs that require network optimization need to be online in the Cloud
*Select Optimization Mode: *Deep optimization : During optimization, external interference sources are identified and analyzed to compute the optimal configuration. It surpasses quick optimization in effectiveness but takes more time.
After completing the AI WIO process, Cloud Pro will generate a detailed report that allows you to view the comparison of network status before and after optimization.
If you find the AI WIO is not suitable, you can still adjust the radio planning manually.
Hahaha alright, that’s a wrap for today’s article—my coffee’s gone, so that’s my cue to stop typing.
Let’s end this with a Bismillah at the start and an Alhamdulillah at the finish. Catch you next time, tech gembelers!.

hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action. Alright, it’s been a while since I last wrote an article. So let’s get straight to it. In this article, I’ll share a solution for those of you who use multiple access points especially the Ruijie RAP series who want to improve and stabilize the performance of your Wi-Fi users. By taking advantage of load balancing features, whether it’s client load balancing or traffic load balancing, you can ensure a smoother and more stable network experience for everyone. AP load balancing balances traffic and connected STAs among APs. This prevents heavy traffic on an AP or excessive connections to an AP.
Signal overlapping occurs between APs on a wireless network. By default, STAs in a signal overlapping area randomly select APs to create connections. As a result, a single AP may be connected to a large number of STAs or bear heavy traffic, affecting user experience. You can configure AP load balancing to balance the number of STAs and traffic among APs in the same load balancing group. This prevents overload on a single AP.
Key advantage: STAs are load balanced, relieving the load of excessive connections to some APs.
Project > Device Config > Wireless > Load Balancing to configure Load Balancing (client and traffic load balancing) ^_^
Click add Load Balancing Group
Client Load Balancing
- Group name: Indicates the name of a load balancing group. You can name the group by area. - Type: Select Client Load Balancing. - Rule: When an AP is associated with more than 10 clients, and the difference in the number of clients associated with different APs reaches 5, load balancing is triggered. - Add APs in the target area to the load balancing.
Traffic Load Balancing
- Group name: Indicates the name of a load balancing group. You can name the group by area. - Type: Select Traffic Load Balancing. - Rule: Load balancing is triggered when the traffic of an AP reaches 300 x 100 kbps, and the difference in traffic between it and another AP with the least traffic exceeds 20 x 100 kbps. If a client is rejected by an AP more than 3 times, the next association attempt will be permitted. - Add APs in the target area to the load balancing group. - This function is supported only on RAP series products. One AP can join only one load balancing group.

hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action. Okay, this tutorial article is very useful as a basic guide to handling common network issues that occur when your provider covers an apartment area where there is more than one broadband internet service provider. The most basic network problem usually happens during activation, when a provider’s technician plugs in all the available LAN cables inside the customer’s unit. Meanwhile, one of those LAN cables is still connected on the panel side to an active switch port. As a result, the switch in the panel indirectly receives broadcast traffic from the newly installed device of another provider. Ideally, when a customer is no longer subscribed, the corresponding switch port in the panel should be shut down. However, if this situation has already occurred, let’s continue using the most basic troubleshooting approach so we can build a clear logical process in resolving the network issue.
The customer in Unit XXX, West Wing, is no longer subscribed. However, the UTP cable going to the panel has not been dismantled. This is to make it easier in case the customer decides to subscribe again in the future, so there will be no need to pull a new UTP cable from the panel to the customer’s unit (which also helps reduce installation costs charged by the apartment management).
** before we continue, I would like to remind you that this is one of the most basic methods, but it is not efficient. I am writing this method solely for the purpose of building a smoother analytical process such as performing MAC tracing, executing switch commands, and manually handling broadcast traffic within the network.
First, the user may complain that the internet package they subscribed to does not match the expected performance. After checking via Speedtest and WhatsMyIP, it is detected that the device is obtaining a DHCP IP address from a different broadband provider, not from the ISP the user subscribed to just like a typical retail customer who would immediately file a hard complaint with customer service. Then a technician is dispatched to visit the unit. Here are several steps you can take:
1 Check the Gateway When the technician is on site, connect a laptop or smartphone to the customer’s unit network, either via Wi-Fi or LAN cable. Once connected, immediately open the IP gateway address in a browser to access the login page of the provider’s device that is broadcasting the signal. If you are able to log in to the device (most broadband ISP default usernames and passwords can usually be found on Google), check the MAC address of that device. In this case, the customer subscribes to broadband internet from an ISP called Nue. However, when the technician checks on site, the customer is receiving a DHCP broadband IP address from a different provider.
Once the MAC address has been identified, you can proceed to shut down the corresponding port or blacklist the MAC address at Layer 2 within your network infrastructure.
2 arp -a If you are unable to access the gateway of the device that is broadcasting, open Command Prompt (CMD) on the technician’s laptop at the site. Type arp -a to view the MAC addresses of devices on the connected network. Once the list of MAC addresses appears, copy and identify the MAC address by checking it on https://macvendors.com/ If it is identified as a device brand that is not part of your infrastructure, immediately trace it and shut down the corresponding port. However, keep in mind that the arp -a command only displays devices on the network that have previously communicated with your laptop.
3 Trace the Full Layer 2 Network Infrastructure If all previous methods fail, we move to the most fundamental approach. The technician should perform a direct bypass test to the Layer 2 switch in the panel (the ISP internet source), connecting the switch directly to the laptop. Then, the Layer 2 team will run the `show mac` command and check whether any switch port is carrying more than two MAC addresses on a single port. If such a port is found, proceed to shut it down. Meanwhile, the field technician should verify whether the laptop is still obtaining a DHCP IP address from a different provider. This method focuses on identifying MAC addresses and shutting down ports one by one to ensure that there is no more than one broadcast source and that the unwanted broadcast is completely eliminated from the network.
4 Default Native VLAN 1 This step is an initial mitigation to prevent looping and unwanted broadcast traffic. Let’s go into the explanation. Using Native VLAN 1 in a network that employs VLANs can create potential looping and broadcast issues if not managed properly. The Native VLAN is an untagged VLAN used to carry untagged traffic. On many networking devices, VLAN 1 is set as the default Native VLAN.
Looping and broadcast issues can occur in the following situations:
- Native VLAN Mismatch: If there is a configuration mismatch between connected devices ex; one device has Native VLAN 1 while the other uses a different Native VLAN—the untagged traffic may be misinterpreted, potentially causing loops. - Double Tagging (Q-in-Q): If a device sends a tagged packet (with a VLAN ID) to a port configured with Native VLAN 1 and adds VLAN 1 tagging again before sending it out, double tagging occurs. This can create network issues and loops on other devices. - Unintentional Inclusion in Trunk Links: VLAN 1 can sometimes be accidentally included in trunk links (paths that carry multiple VLANs across the network). If Native VLAN 1 traffic enters a trunk and is misinterpreted by the receiving device, it can cause looping.
To avoid these problems, careful VLAN configuration is essential. Best practices to prevent looping caused by Native VLAN 1 include:
- Change the Native VLAN: Change the Native VLAN from the default value (1) to a VLAN ID that is not used by other VLANs, reducing the risk of loops. - Separate Data and Management Traffic: Use different VLANs for user data and management traffic. Avoid using VLAN 1 for user data. - Monitoring and Understanding: Monitor VLAN configurations on all network devices and understand how VLANs and Native VLANs operate to identify and fix potential issues before loops occur.
Therefore, to prevent looping and broadcast, the Native VLAN must be redefined and changed from the default VLAN 1. In this setup, I use Native VLAN 800, and on the opposite side, Native VLAN 975 is configured. Only the required VLANs are allowed. When properly configured, VLAN 1 traffic will no longer pass through, making this method effective in preventing network loops and broadcast. The MAC addresses carried by VLAN 1 need to be analyzed.
Based on this case study of basic network issues with an ISP covering an apartment area, this is one of the recurring problems. Understand the concepts of handling both Layer 1 and Layer 2 network issues. Hahaha alright, that’s a wrap for today’s article—my coffee’s gone, so that’s my cue to stop typing.

hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action. Because I just came down from the mountain and we’re about to enter the month of Ramadan. today I’m going to invite you all to briefly review and level up our skills, from GPON FTTH to GPON FTTR.
FTTR (Fiber To The Room) is an advanced fiber optic networking technology that extends optical cables directly into every room, rather than stopping at the home as with FTTH. This technology delivers stable gigabit internet speeds, low latency, and seamless Wi-Fi coverage throughout every corner of the house making it ideal for 4K streaming, gaming, and smart home applications. Key Advantages and Features of FTTR: 1 Stable & High-Speed Connection: Uses ultra-thin, transparent fiber optic cables (millimeter-sized) installed in every room, delivering more stable speeds compared to conventional Wi-Fi. 2 Wide Coverage: Eliminates weak or “dead” Wi-Fi zones caused by concrete walls or multi-story and large home layouts. 3 Main Components: Consists of a Master Unit (acting as a central hub/mini OLT) and Slave Units (Wi-Fi 6/7 access points) installed in each room. 4 Aesthetic Installation: The fiber optic cables used are extremely thin and flexible, ensuring they do not disrupt interior aesthetics.
Here, I am using GPON ONT devices from ZTE, specifically the ZXHN G8605 (ONT Master) and ZXHN G1611 (ONT Slave). Next, here is a simple topology for testing Wi-Fi roaming on this FTTR ONT setup.
1 Go to IP ONT and Login ONT Master with superadmin account: admin | Web@0063
2 Create dial-up accounts using either IPOE or PPPoE (here, I am using the PPPoE method). Go to Internet > WAN > WAN Connection, then fill in the settings according to the DHCP/internet configuration you have prepared.
After that, make sure the WAN status shows Connected.
Internet > Status > WAN
3 Switching Mode In this method, the OPTICAL port on the ONT Master will be assigned to forward the fiber cable connection to the ONT Slave in each room (via a fiber optic splitter/roset). The uplink of the ONT Master will then be switched to a LAN port.
Go to Management & Diagnosis > Uplink Mode Switch > Uplink Mode: LAN > Uplink Port: LAN 1.
4 Routing Next, we need to direct the WAN Connection routing to the WAN profile that we previously created. Go to Local Network > Routing > IPv4.
5 Speed and Roaming Testing If the fiber cable connection between the ONT Master and the ONT Slave is functioning properly, the Wi-Fi settings will automatically synchronize from the ONT Master. To test roaming, walk from the ONT Master area to the room where the ONT Slave is installed. Check whether the signal drops during the transition or if the connection remains stable and seamless.
Click the Home menu. In the WLAN Device section, you will see the devices connected to the ONT Master’s signal, while in the LAN Device section, you will see the devices connected to the ONT Slave’s signal. sample: device client (infinix) roaming done.
hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action. Okeii, I’m sharing this tutorial now because tomorrow my friends and I will start another mountain hiking trip. After such a long time of only stepping on the bathroom scale, we’re finally climbing a mountain again. Don’t miss us too much, guys. Please pray that we return home safely. Alright, this tutorial is simple and made to help beginners like me. This method applies to all Ruijie access point models that are connected to the cloud.
Alright, first let’s look at this case. On the monitoring page, the access point shows the channel usage status as overload and busy. RF Channel 1 is a 2.4 GHz frequency channel. Most likely, the location is experiencing interference from other Wi-Fi access points, mobile phone hotspots, or even radio transmitters operating in the area.
1 As a first step, it is best to scan the frequency/channels at the location using applications such as: inSSIDer, WiFi Explorer, NetSpot, WiFi Analyzer, WiFiman, or Vistumbler, to identify nearby Wi-Fi signals and the channels being used.
2 Click on the access point you want to tune, then go to the configuration menu to adjust the channel to one that is more idle or has less interference in that area.
3 Select a channel with minimal or no interference. Once selected, Adjust the channel power as well > click Save.
you can see that after tuning the access point’s channel and frequency, the monitoring shows it has improved. Next, feel free to test it yourselves start by moving around and testing the Wi-Fi connection.
