Internet Sharing Painfully Slow

[eco]

I have used Internet Sharing from my iPhone to both my iPad Mini and my Macbook Air for several months with great success. However, it is now painfully slow using both Bluetooth and WiFi sharing.

I get around 40 MBit/s on the phone, and less than 1 MBit/s on a connected device. This holds true for both my Mac and my iPhone (6). Connecting the phone to the computer with a cable though, everything runs smooth (no speed loss).

I have tried the usual things, such as
- Disconnect and reconnect all Bluetooth devices on both iPhone and iPad.
- Turn on/off Bluetooth
- Reset network settings

I still haven't tried full resets of any device. I have however also tried two other iPhones (6S and 5S) connected to the iPad. Both showed similar crappy speeds when connected. I also used Internet Sharing via WiFi to a Windows computer, and that worked fine.

Any thoughts? In desperate need of help...

Just chatted with online support. Reset network settings and works perfectly fine now. It's under Settings>General>Reset>Network Settings. Try that before heading to Genius Bar tomorrow.

Thanks justinvirk. I have reset network settings on both devices (iPhone and iPad), with no success.

Any other suggestions?

iOS 9 features a new Wi-Fi Assist option that basically switches to your Cellular connection automatically whenever it detects problematic WiFi connection. Toggle this option to on and then off from Settings > Cellular > Wi-Fi Assist to see if this fixes the problem. Your mileage may vary with this.

Use OpenDNS or Google DNS

In certain situation when your Internet is too slow, changing your ISP fetched DNS server to an OpenDNS or Google DNS can fix that issue, just like on a computer. To do this, simply tap the ‘i’ button next to your connected WiFi network, and tap the number appearing next to DNS. Here, you can enter a Primary DNS and Secondary DNS, both separated by a comma. Once entered, simply exit settings and take Safari for a spin.

Google DNS: 8.8.8.8, 8.8.4.4
OpenDNS: 208.67.222.123, 208.67.220.123
