4G browsing session on X750

I’m using a 4G card with my x750. The wan works, and my mail client works fine, however web browsing (with different browsers) doesn’t. Maybe it’s a DNS issue? Any advice? Thanks.

Do you have any DNS Settings?

I think I fixed it by changing the APN. But now, even with the right APN the speed is very low considering it’s a 4G SIM (also recognised as 4G by the x750)

Different apns have an effect on the rate. Can you detect any other apns in your drop-down list?
Alternatively, you can ask your carrier about APN Settings
