S9+ Wifi problem (Wired) Help me.

[Vishnu_Pv]

Hello Guys, 

I have very very wired problem with my home wifi. Im using Asianet Fiber Optics connection and Im using Optilink Dual band wifi router. After upgraded to One UI (9.0 Pie), my s9+ works fine on this wifi for some time. After that, wifi will not work on my phone. To make it work again, I need to turn off wifi and turn it on. Then again it will work for few minutes, then again the same problem will come. Other phones in my home dont have any issues. Also other service provider wifi doesn't have any issue on my phone. So the problem is, Asianet wifi with One UI. When my phone was on Oreo (8.0), there were no problem. I dont know how to fix it. When the problem occur, the downloading arrow of the wifi icon is disabled. Only uploading icon visible. Then I have to turn off and turn it on again to make it work. Any one have this issue?

Any one having the Asianet fiber optics connection and running one ui on your phone?

this happens when your router can't support multiple devices connected equally with fhe bandwidth..you've got two options..either increase your bandwidth so all the devices can get shared or upgrade your wifi equipment(but issue can remain still coz usually the optical modem/router is trash which is given by the company).

Ok bro. Let me change the router once and let's see

noo..first do some troubleshooting..disconnect all other devices connected to that wifi and check if your phone loses connection..then start by adding 1 device and check how many devices can run simultaneously..
