2.4Ghz devices periodically dropping off router

[Rowan_clarke]

Since joining TT all of my 2.4Ghz devices have been periodically dropping off wifi and then reconnecting a few minutes later.  This is apparent and logged as I have a Nest doorbell they only works on 2.4Ghz and is only 1m away from the router. Each time the doorbell disconnects I get sent an email notification, of which I have lots now. I have tried changing the wifi channel, first seeing which were free using a wifi analyser.  But this hasnt helped. I suspect I have a faulty router as this never happened with my old Sky router. Is anyone else experiencing the same problems?

Slow speed, intermittent dropouts, breaks in the signal, or no signal on some or all devices, might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a by-product of the popularity of Wi-fi.

Generally speaking, the 2.4GHz band suffers much more from interference than the 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

To enable me to help you, please can you specify the make/model of TalkTalk router that you are using?
