I have converted Lenovo IdeaCentre 510S-0I8SH into a router and currently running a tethered android phone to give it LTE connectivity. However, it is not entirely stable and having a always connected battery does not sound like a good idea.
So I am considering a couple of options:
- mPCI and old access point.
Lenovo unit has an M.2 Wifi module that I can replace with LTE module and cute little antena on the back: https://d2j6dbq0eux0bg.cloudfront.net/images/22287660/3169266588.jpg I thought of replacing it However I figured out I would need a SIM adapter and the card ~70 USB + shipping. Are there cheaper options?
- LTE USB dongle.
I saw some used cheap (Huawei e3372 10 EUR) dongles... heard they work ok but are power hungry. I have a USB power splitter that should double power supplied to it. Would it be enough power to be stale?
- LTE router.
I found some cheap used LTE routers (Huawei B315s-22 25 EUR) I would prefer to have fewer devices and less space taken up by the setup so I would prefer the dongle but is this a more stable solution?
What is the most stable solution?
