I updated the system update 3 days ago and since then I have had issues staying connected to WiFi. I'm constantly getting an exclamation mark next to the WiFi icon and it dips or lags every few minutes  The same happened to my partner's s7 when he updated the day after. Did a quick Google search and this has been a common theme for months. Anyone else having this problem?

I am also having this same issue with Wifi after the update to Oreo. Tried clearing the cache and forgetting the network and still the same. Did you manage to find a fix? 

 

 


No I didn't unfortunately 😔 Samsung don't seem to be acknowledging it either so it looks like it's here to stay. What phone do you have?

I don't want to jinx it but my partner and I both wiped cache partition on our s7s and they seem to be much better. It's worth a try.

For me there was no other way than to reset my S7 edge back to factory settings. Now I have access to my WiFi again and my phone says it's up to date.

I tried a cache wipe and the Wifi is still laggy. If I turn the wifi off and back on again it seems to be fine again for a while.

@Akort were you able to connect to your wifi at all before the factory default? The issue I am having is not that it won't connect to my wifi but rather when it does connect the connection is not very stable and I get a lot of lag when browsing websites and facebook etc. If I turn my wifi off then back on again then it will be fine for a while.

Also if I try pinging my phone from my PC I'm getting high latency and packet loss. This is while the phone is within 1 meter of my virgin media Super Hub 2.

Well, it says the last update is from April 2018, which seems to fit the updates that have rolled out in my country. The weird thing, it IS in Oreo now. (not really that knowledgeable about these things, so maybe I said something dumb there)
However, it needed to verify the reset by connecting to my Google account via a WiFi connection. As soon as I entered my password, it picked it up. So yes, resetting to factory settings helps if all else fails.

No, I was not able to connect to my WiFi at all. I have told it to forget the connection a couple of times, cleared the cache and such, but nothing would work. It would just try to connect for 10 seconds, then say there is a verification error for a while, after which it would just try to reconnect. The only internet I had came from my mobile data package.
