Wi-Fi is slow everywhere, especially at busy times
In an office building with neighbors, dozens of APs share the same handful of 2.4 GHz channels. They all interfere and throughput collapses.
Try this first
- 1Open a free Wi-Fi analyzer on your phone ("WiFiman" or similar). Look at how crowded channels 1, 6, and 11 are.
- 2Is your AP on a channel other than 1, 6, or 11 on 2.4 GHz? That is always wrong, regardless of how busy it is.
- 3On 5 GHz: enable auto-channel in your controller, or manually pick a channel your analyzer shows as empty.
- 4Where possible, push devices to 5 GHz by lowering the 2.4 radio power or offering some SSIDs on 5 GHz only.
When to bring us in
In genuinely crowded buildings only a physical survey helps: lower transmit power, smaller cells, more APs at less power. We do it in half a day.

- One room or corner has no or bad Wi-FiNot always "add another AP"; often one is poorly positioned, or there is a metal wall in the way.
- Internet is suddenly slow for everyoneThree suspects: your provider, a colleague soaking the line, or a backup or update kicking in unexpectedly.
