Hello,
I’m quite new to Mikrotik devices and am encountering high latency with WiFi connections on the hAP ax2 and was wondering if anyone can offer some insights about what might be the problem.
The goal is to use the hAP ax2 in combination with a hAP ax3 (as router) to extend WiFi coverage in a small apartment. To troubleshoot the issues with the hAP ax2, I have tried to simplify the setup and tried to look at the issue in isolation.
The (test) setup and observations are as follows:
- The hAP ax2 is updated to the latest non-beta software (RouterOS 7.15.3) including firmware, and I’ve performed a configuration reset.
- The hAP ax2 is directly connected to a PC via ether2 (for WinBox connectivity only), cable length 1.5m; no other wired connections, no internet configured. Ping from PC to hAP ax2 is about 0.28ms.
- Only the 5GHz radio is enabled, and I’ve chosen a less occupied channel (120) based on a frequency scan. In addition, channel width is set to max 40 MHz. Generally, the channel selection and width did not seem to have much of an impact for this particular problem. Most WiFi-related settings are at their default values.
- Two mobile devices (an iPhone SE and a Samsung S22) are connected as clients, distance from hAP ax2 about 50cm, line of sight. The devices were not sleeping during the test.
- When I ping from the hAP ax2 to either device, I observe overall bad latency and intermittent spikes.
Please see hAP ax2 configuration export and possibly relevant attachments below.
