I was just running a few speed test from my iPhone connected to my TMHI (G5AR) and noticed terrible speeds. About 220 down and 7 up. ( I ran multiple tests to different speed test providers and all were terrible).
So I figured to try a reboot with HINT Control, but kept getting the message it couldn’t connect to my gateway, even though I was connected.
That let me down a few rabbit holes, when I remembered having this issue before and all those times, performance was terrible.
Going into my phones WiFi settings I saw my gateway being blank and no IPv4 IP addresses. That made me want to try using IPv4 only, but how? No way to disable IPv6 on IOS.
I then found an online discussion that said going into your WiFi network settings on the iPhone, then go to DNS, set it to manual and remove the IPv6 addresses.
This worked … I got an IPv4 IP address.
I reran my speed tests and now getting 600+ down and 40+ up.
TL;DR, it seems that with a IPv6 only connection my network speeds for both up and down are so much slower than when using IPv4. And yes, I can’t say I fully understand IPv6.
