FYI, Criticisms:
- I’d retitle this post as 'HOW-TO: Mango (GL-MT300N-V2): Setting up a Huawei e3372h-607 USB LTE/4G Modem".
- Please post what firmware & release version your Mango is running.
- GL GUI → System → Upgrade
- This forum support the Markdown language.
- Numerically ordered lists, bullet points, code formatting, arrows, etc., can greatly improve readability (eg: -> == → ).
- Markdown is/is getting to be pretty common on forums/web apps (insert jingle here).
- Thanks for posting; this will be valuable to point others towards as I’ve seen more than one post about this modem.
- Make a backup of your now custom setup.
