Updated my 6s and now my WiFi speeds are at a crawl mostly under 25mbs in the same room as a laptop getting 75mbs download speeds.
I’ve done a Forced Restart
Toggled WiFi on/off
Forgotten WiFi networks
Reset WiFi networks
Turned off Location Services
Etc etc etc
The only thing I have done is reset the entire phone 📱
Anyone else reporting these issues?
I have found two fixes for the slow WiFi issue of iOS 11:
1: switch to a 5Ghz WiFi network instead of 2.4Ghz
2: if you don’t have a 5Ghz option, then turn Bluetooth off.
Both of these put my 6s’ WiFi download speed back to where it should be. The speed was cut in half by iOS 11 and it took me days to figure out the root cause and to identify these two fixes.
Hopefully Apple will fix this issue soon. Good luck.
Worked for me! Been suffering for weeks thinking it was my WiFi!
Since apparently I can't delete my post above. I'm going to just blame my internet provider at this point. Just disregard everything I said up here ^^^
Didn’t work for me.
I tried turning off beamforming on my NetGear R7000 Nighthawk router but it made no difference on my iPhone 6 and brand new iPad Pro (both running iOS 11.2.2).
This absolutely worked for my phone and my wife’s. Good work Chaz!
Me? What did i do?
In sound options you can reenable the buttons...
I too I too have similar issues , just that it’s with my iPad
my android phone sitting practically next to the iPad clocks amazing download speed on same wifi.
Same here. Just ran test using Speedtest on my iPhone 6S and Samsung SM J327V.
iphone download 12 Mps, Samsung 60 mps. Crazy!!!
Glad it worked for you. I could try it with my home router but cant make changes with my office router.
So it’s still an unresolved issue for me.
Hi Leddra2k
Could you please tell me how you roll back to a previous IOS. As since I’ve updated my iPhone 6s to IOS 11.3 my WiFi as been rubbish.
Thanks Craigy72
It's not a bug. Apple clearly does this on purpose where they mess with your wifi connection. It's like that battery scandal thing all over again. Waiting for the class action.
ios 11 slow wifi speeds
