I,m with TalkTalk as my ISP and just lately I have found that Checking for Updates..it comes back with Network Error.
My last Update was on the 23rd September.
It just buffers for about 5 mins then gives me Network error.
The Wifi is working.....when I change to Mobile Data there is no problem.
Have reported this to TT as it looks like their problem.
I'm in the UK on B.t and I have a similar experience @Gerrymac
If i check for software updates using my Home Broadband Wifi on my Note 10+ 5G it just hangs for quite a while, and I then get a couldn't connect to server pop up message.
If I switch to Network Data then that's all good.
I'm not sure wether this is a wifi connection bug or not.
Perhaps send a bug report to Samsung via the Samsung Members App / Samsung + .
My advice comes from being a UK Samsung Phone Owner.
I have no affiliation with Samsung.
