Hi, similar but not the same has been asked before. Out of the blue (so to speak) my Galaxy S8+ won't connect properly to wifi (it connects but has not internet connection). I have tried the obvious ones including restart, forgetting wifi network. All other devices (my wife's iPhone, iPad, laptop and smart TV) connect, so there is something going on between the router and the phone?

My local phone shop suggested that my router (Vodafone) may have decided that the phone is a 'treat' and the firewall blocks it. It appears in the admin site of the router when connected to the network but I cannot work out whether, and if so where, the "this is a threat/virus" would come up in the router website. 

any other suggestions? 

thanks in advance,

 

Martin

Update - I rang my broadband provider and they updated my router software remotely, not forgetting to mention that, as a loyal customer I qualify for bla bla bla ... Anyway, all good now, phones connecting now and remain stable. Thanks for your advice, folks.

Can it connect using cellular connection? If it connects to the router and it's pulling a valid ip address (not one starting with 169), then the issue isn't your router. Check your NAT setting, that should mask internal addresses and allow connection outside. However, the firmware and drivers on S8 series have been exploited because the phone is still being used but mine still connects to network.

Hi, I am afraid that some of the words/concepts in your response are beyond my understanding of phones/internet. However, to answer some: yes, the phone connects to 4G without a problem. The IP address shown begins with 192. NAT setting??? I have also just noticed that it suddenly connects to wifi, but can only assume that there is now a temporary problem. Maybe it's time for a new phone ... :-(.

192 means the connection from phone to router is good. Getting a newer phone is also an excellent idea as the S8+ hasn't been supported in terms of security updates in a long time. Mine is only used for offline games.
