There are a variety of causes for Wi-Fi problems, the rarest of which is a defective router.
Disconnections can occur when switching frequencies, for example, when devices switch between the 2.4 GHz range and the 5 GHz range. This can be avoided by giving both ranges different names. Particularly in the 2.4 GHz, heavy frequency usage can lead to devices having a Wi-Fi connection, but no data can be transmitted over it. In this case, choose a different, unused channel. In the 5 GHz range, there are other users such as radar, so the end devices must support DFS and TPC. Devices that do not support DFS cannot use the correspondingly marked channels. When DFS changes channels, there is a brief interruption in the Wi-Fi connection. Select another channel if necessary.
Thank you @blablup , I have tried disable 5Ghz completely and used only 2.4Ghz however that did not help. I have also tried to manually choose between channels with help of Wifi Analyzer app that also doesn't seems to fix the problem. How do I rule out a faulty router ? Does O2 replace old router as I am renting the routing with my contract , any thoughts on getting a higher end router may be Fritzbox ?
Thank you @blablup , I have tried disable 5Ghz completely and used only 2.4Ghz however that did not help.
This is expected because 2.4 GHz is much more used. When choosing a channel it is import that you choose one any other is using.
A sign of a faulty router is that disconnects are happening constantly with all devices. If the router from o2 is demonstrably defective, it will be replaced by an identical, possibly used device. So you have no advantage by the exchange.
What is always worth a try: Turn off the router once for 5 minutes.
Hello @RAK1 and welcome to our o2 community :-)
If you are using a wifi connection there are many possible reasons that can interfere with the stability and dara rate of the transmission.
As @blablup already stated it may help in some cases to give the wifi networks with 5GHz and 2.4GHz different names so that some devices are prevented from changing the frequencies.
In some cases also the environment may have a negativ influence on the range of the wifi network. In such cases wifi repeaters may offer a solution.
If there are many different devices that are used for example in a smart home network there are also router that offer more functions regarding this.

Hallo zusammen...I have also problem with my router...every day exactly at the same hour (02.45) my router restart alone...what can I do to stop this?it's very annoying especially when I am working at my laptop....I tried all the usual things...hard reset blah blah blah....
Hi @Kavalero13
Welcome to our o2 Community.
Just to be clear, does your router really restarts every day on the same time,
or is it just a reconnect, which would be a complety normal procedere every 24 hours
