How can I disable IPv6 on NEXP1GO / EM7535?

[tetranz]

I have a NEXP1GO / WG3536-P router with a EM7535 modem. Running the latest WiFix firmware.

It's been working very well. I've been trying different plans. I did a month on Net10 then a month on Page Plus and this morning I went to the AT&T tablet plan. I run WireGuard via Windscribe which works great.

I noticed that I'm hitting the stream saver when I test at fast.com. That itself is not a problem. I can disable the stream saver on my account and I don't stream much anyway but it puzzled me how this is happening. Then I figured out that I'm connecting to fast.com / Netflix with IPv6 which is not going through WireGuard. Windscribe doesn't support IPv6.

My WAN is getting both IPv4 and IPv6 addresses. I have WAN1 "Protocol: DHCP client" with a 10.* address and also a WAN1_6 "Protocol: Virtual dynamic interface (DHCPv6 client)" interface that appears with an IPv6 address when the connection is established. Restart and Stop buttons on WAN1_6 are grayed out and it has no settings in "Edit".

How do I stop is connecting with IPv6?

Hello,

My preferred way to get rid of IPv6 without changes in interfaces / start up connection scripts:

Thanks. That worked. I just made a backup and edited my existing file. Streaming is fast now regardless of stream saver.

Great. I think this is actually a bug in ROOter/OpenWRT because when one creates a connection profile in the ROOter/OpenWRT GUI he can specify the required protocol. The problem is that later the system overwrites this setting and automatically uses IPv4V6 instead.

I was looking for it but I don't see anything related to IP addresses in the connection profile.

Its the drop down under the APN setting, but only in the latest firmware. If you are using the NEXP1GO firmware, you have it.

Thanks, I don't know how I missed that but ... I think I agree with 56387f above. I put my script back to original and changed that setting to IPv4 but it still connects with IPv6. I hardcoded the script again and it's back to IPv4 only with that setting at Default.
