Hi Vaughan, I dont have a setup that I can send a config for handy. But i think i was using 1500. The modem was directly connected to the router. The apn and all 4G services and nat are controlled in the stick nkt the mikrotik as they are a router and basically present an ethernet connection over the usb port.

Hello Andrew,
Can you advise what MTU you’re using?
I am using, the default 1500.
Also can I confirm that
1. You’re not using a powered USB hub, you have your E8372 connected to your Mikrotik directly?
2. Have you been able to set the APN for your 4G ISP within the Mikrotik?
Thanks
Vaughan

That sounds like a mtu or mss issue.
I have used these devices very successfully with mikrotik. Including on a 10m usb extension cable with built in amplifier.

Hello,
I've been testing an E8372 USB 4G dongle with an RB951Ui-2HnD router
According to https://wiki.mikrotik.com/wiki/Manual:Peripherals the E8372 works
My experience has been that it "works" to some degree.
Connecting to some Web sites (e.g. www.smh.com.au ) works consistently, yet connecting to other Web sites (e.g. any speedtest site does not work at all).
In contrast, when the dongle is connected to a USB3 port on a Windows PC, the performance of the dongle is perfect. Also accessing the Web portal of the dongle seems quicker when the dongle is attached to the Windows computer versus the Mikrotik.
I'm pursuing a couple of avenues regarding troubleshooting
- The Mikrotik has a standard USB2 port and this may not be supplying the required power for the dongle
o I have ordered a USB2 hub with an external power adapter which will supply the power requirements of the E8372 (5V and 750mA). So will test this soon.
- I've not been able to configure the APN for the 4G service provider in the LTE properties. There is no error, but the APN is not saved. I am able to save the APN in the 4G dongle's own firmware/web portal, but I'm not sure whether this is used when the traffic is traversing the LTE link of the Mikrotik
So the questions that I have are:
1. Is anyone else using an E8372 with a Mikrotik?
a. If so, what is your config?
b. Are you using a powered hub
c. Did you need to save the APN in the LTE properties?
2. Is anyone using some other 4G USB hub with a Mikrotik?
Thank you
Regards,
Vaughan

I have seen this issue before many times, I set my MTU down to 1300 and it just works. Otherwise, it was always a little flakey depending on the phase of the moon / how windy it was / if the sun was over the yardarm, and was killing VPN traffic. An MTU of 1300 wasn't worked out by trial and error, as I couldn't be bothered as it kept changing. It is an arbitrary number that just worked :) On 29 March 2018 at 09:10, Andrew Gilbett <andrew@gilbett.net> wrote:

Hello Stephen, I just tried using an MTU of 1300, and unfortunately for me no sites load at all with this MTU. However I appreciate the feedback. I will investigate further. By the way, the powered USB hub has arrived, and unfortunately it is not the answer either Regards, Vaughan From: Stephen Schwetz [mailto:stephen@schwetz.id.au] Sent: Thursday, 29 March 2018 12:19 To: MikroTik Australia Public List Cc: vw@zeb.com.au Subject: Re: [MT-AU Public] Huawei E8372 I have seen this issue before many times, I set my MTU down to 1300 and it just works.

I would not adjust the MTU instead you need to use mss-clamping. Mike
