I switched from an Iphone to android. The wifi is horrible. Its slow and instagram and twitter and youtube will automatically load videos in extremely low quality now. Not only that i cant even download updates as it says network issues. And its not cause of one phone because i went through this with the LG G6 and now the v30. Ive disabled IPV6 to try to fix it but nothing. It should be noted i use a wifi extender in my room called the actiontec WCB3000N but even on school wifi which yes isnt the best but worked good enough on my iphone is horrible on both of my androids ive owned. Any help?
