    For last 15 Days and I'm frustrated with the Wi-Fi on my phone. I I'm using Oneplus series phone for last 6 year but have never faced such issues.

    I have been facing this repeated disconnection on my wifi since the last os update esp last few days. I have tried everything like clearing Wi-Fi cache, wiping cache from volume+power button, factory resetting but of no use.

    I'm really frustrated as without Wi-Fi no use of having smartphone.
    Please help me quickly.

    The update did not fix this. I will have to buy a new phone since this is unbearable. Can anyone recommend a brand that doesn't break their customers phones?

    Just roll back to the previous version stable update. I'm planning to do that if I don't receive an update in a month

    I have been in constant communication with oneplus support and they have not been willing to assist me in reverting to Ox10. Is there a guide somewhere on how to proceed? Have you done complete reset yet? I fail to see how this would help but will try today.

    OnePlus guys will never tell you how to revert back to the previous version. Just search it on XDA. You will find a way.

    Thanks for raising this issue. Having the same problem with my OP7 (GM1901) after updating it Android 11. Phone was working fine before the update. Tried resetting everything except the factory reset which I really don't want to do. I am frustrated since there is no real solution offered by oneplus team. Created another thread just to draw their attention

    U might be using jio fiber I guess and if not then two wifi connection at the same place might exist. The workable option for now is to forget one connection. I have a Jio fiber connection and wifi disconnection was happening very frequently. I forgot one of the network and just connected to one now. Working fine as of now.

    I don't know how it could be related to Jio fiber. By the way I'm using Airtel fiber and the issue has nothing to do with ISP. it's purely oxygen issue and I will be surprised if @OnePlus can fix this soon.

    I'm pretty sure the phone isn't the problem. By default, the router has a limit on the number of IP addresses allocated and the reservation time for the device. For example, a router has a limit on the address pool of 50, and the reservation time for a device is 6 hours, which means that when 50 IP addresses have already been issued, 51 devices will not receive an IP until it becomes free. And now smartphones use a new mac address every time they connect, so the router tries to give them a new ip. What happens, you connected to the network 1 time, got an ip and a mac for 6 hours, went for a smoke, left the wifi zone, came back and connected again, but got a new ip and mac, and the old one hangs in the router for 6 hours, this is how the entire pool of IP addresses issued by the router is clogged. To fix this, you need to expand the number of issued IPs to 200-300 in the router settings and set the registration time to about 1 hour so that they do not get stuck.
    I did all this at my work, as I began to notice that many computers and phones could not connect to the network. I saw my phone with five different ip and mac addresses, and the same number of registrations of one person's iPhones were hanging somewhere.

    Are you talking about Oxygen That is what I'm on, and I can't see any improvement. Wifi goes up and down like a yoyo. I run Wifi Analyzer app in the background and it tells me that my connection to the router is fine without any dips. Still the phone decides to disconnect and reconnect continuously, often to a network with poorer signal. Downtime is 3-10 seconds every time.

    Yes, the issue is still not resolved. I checked it, but I've found a way to downgrade to the previous version of Android so if I get frustrated with this I'll downgrade maybe

    Hello all!
    After upgrading to Android 11 (11.0.2) I am not able to connect to my WiFi's 5ghz band rather my phone isn't even detecting the 5ghz band even if I am standing in front of the router. On the previous build (10.3.8) this never happened.
    The problem is 2.4ghz band provides very less download speeds, is there any solution ?

    I tried manually entering 5ghz SSID, resetting wifi, bluetooth, network settings also wiping device's cache memory
    But still no luck
    Please help me out , also is anyone facing the same problem ?
