Wifi crashes

Question

WiFi

Good afternoon. The problem is this. The office has a Wi-Fi router. From time to time, Wi-Fi began to fall off, i.e. stupidly disappears from the list of wireless networks. Only reboot helped. They did a reset - 0 sense. They took a completely new one. Set up, worked for a day and began to fall off again once a day. Moreover, according to the indicators, everything is normal, everything works on the cable, but there is no wireless. Reboot - everything works. What could be? Well, the new router cannot suffer the same disease. Routers even from different manufacturers

Answer 1

Some equipment (particularly Android smartphones) look for networks up to channel 12, and if the router automatically takes channel 15, they don’t see it, try manually setting channel 7-8. In general, list what kind of equipment you have for distribution and reception, maybe something else will come up.

Answer 2

I also agree that competition can be the culprit.
Try looking at Wifi with a scanner like the free inSSIDer . Find less loaded channels based not on the number of networks per channel, but on the power in relation to you. Those. choose either an empty channel, or with the weakest networks. Surely the router is configured to automatically change the channel, try setting it to specific channels.

Answer 3

www.nirsoft.net/utils/wireless_network_view.html - run for a few days,
select the freest channel, explicitly specify in the router settings.
The router is better dual-channel, with external antennas.

Answer 4

Check the quality of the power supply of the router, at low / high voltage there are glitches that also occur due to the quality of the power supply.

Answer 5

Do you have a microwave next to the router for an hour? )
