Hello, I have an O2  HomeBox router at home, Recently I  notice there has been frequent disconnections with Wifi devices connected, I also tried to disable 5Ghz band however with that I get a No-Internet message on some devices however at the same time there is No problem with other devices connected. I suspect there is problem with the WiFi router as it is not consistent across devices. I tried to reset router and all steps which is recommended by the O2 service app but do not seem to fix the issue. I am using 02 router which is on rent with my contract. Looking for suggestions and support.

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.

Regards,

Lars

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 

Best Regards Matze
