Yes, I have an issue too. I never downloaded the software for IOS 14.1 and last night I had no wifi at all. I still don't have it and have done everything to fix it. Nothing as mentioned works. I am at a loss and I'm wasting valuable data rates now as well thanks to this unwelcomed update without mention of it to your customers APPLE. This is more than disappointing! I also have bad battery drain to go along with this. I never update unless I wait and read the reviews and this time I wasn't even asked. I have done all hardware fixes as mentioned to router and reset my iPhone only to find it still doesn't work. PLEASE FIX THIS IMMEDIATELY and make sure that your software works properly BEFORE putting everyone listed here and owning an iPhone in a predicament for which we cannot get out of. This is not how you take care of your loyal customers. How would you like us to turn the tables on you? Poor customer service!!! Do what needs to be done and get this fixed fast! We have lives and businesses to attend to.

I updated to IOS 14.2 today thinking it would help the Wifi issue, but nothing has changed it. Apple, please FIX THIS! Now anything attached to my router will no longer work. When will you have a fix for this?????? Soon I hope!
