There are no issues with internal network, but the wireless latency is very high (average wireless latency of 300–500ms).
When connected via AP and sending pings from a laptop to the gateway, the response time occasionally spikes significantly (upto 100ms). When connected via a wired connection and sending pings to the gateway, there are no issues at all (all 1ms).
When the response time spikes, the wireless connection to the POS server DB becomes unstable, causing inconvenience for users connected wireless. Since the problem only occurs on wireless and not on wired connections, it seems that interference is the most significant factor.
I have already adjusted TX power and enabled band steering, but the same symptoms persist.
Are there any additional measures I can take?
