Various iPhone models may exhibit extremely slow data throughput when connected to Wi-Fi networks. This can result in sluggish loading of web pages, YouTube content and more.
Fix
This problem can often be solved by simply changing DNS servers. On your iPhone, while connected to a Wi-Fi network, follow these steps:
- Go to Settings > Wi-Fi
- Tap the blue arrow next to the currently connected Wi-Fi network
- Tap DNS, then delete the current entries and enter the following: 208.67.222.222, 208.67.220.220 (or you can try Google’s public DNS servers: 8.8.8.8, 8.8.4.4)
- Tap return

Hello appletoolbox,
Because of your solution (dns entries), my wifi speed is up to speed, and equally fast as my 3GS, so thank you very much!!!
What if your suggested dns entries stop working, are there any other ones that I can try? (is there perhaps a website with a whole list)
At other wifi spots the dns entries did not appear to work, do you have any idea why that could be, and how it could be solved?
Again thank you so much for all the help.
Best regards,
Rudy

sounds like you disconnected the wifi and didn’t re-connect it correctly.

Been having slow wifi problems for 7 months. Tried the first entry and from my quick check my browser is working a lot faster then before. Thank you, hopefully it keeps up!

Worked great! For those of you wondering about how it works (or wary of changing your DNS settings to an IP listed on a random website – which is a very dangerous thing) you can read more about the project that provides the DNS servers here: http://www.opendns.com/business-solutions/premium-dns/benefits/
Just in case the comment system deletes the URL just Google OpenDNS. Hope that enlightens some of you.
