Hello, I've been doing a load of research trying to figure out the best hardware to get for my needs. I'm looking for a LTE modem setup to use for a desktop computer (Win 10) in a converted van. I will be utilizing Visible and possibly AT&T service. The EM7565 seems to be the best modem option to allow the most flexibility of carrier support based on the bands provided. I however am torn on whether I should get a usb enclosure or a WE826-T2 router for the modem. I do not need wi-fi, as the only device I care to have connected is my desktop, so it seems wasteful to grab the WE826-T2 but I'm not sure if I will have limitations (such as control of TTL and other parameters to have the data metered as mobile and not hotspot data). If it is possible to get a usb enclosure for the EM7565 and keep the ability to change parameters, what would you recommend? Since this is in a metal van, is it possible/advisable to get antennas with an extension/long leads so I can place them near a window or on top of the roof? I apologize in advance if I'm off the mark completely, new to wireless hardware.
Thanks!
An external usb enclosure for the modem works great if connected to an OpenWRT router, but not so much when connected to a pc. Here's why:
You will have to supply external power to the box (draws quite a bit of amps).
You will have to run some kind of modem control software on the pc in order to connect to the mobile network.
You cannot share the pc's internet connection, because the TTL settings do not propagate beyond the pc.
To set the TTL, you need to send the commands below.
In a Windows CMD prompt (WinKey + R, enter CMD), copy and paste these two commands one by one:
netsh int ipv4 set global defaultcurhoplimit=65 store=persistent
netsh int ipv6 set global defaultcurhoplimit=65 store=persistent
Using a WE826 as a modem interface has several advantages over using an external USB enclosure.
Here's why:
It plugs into the ethernet port without tying up a USB port (also no extra power draw on the USB bus).
Makes it easy to set the TTL/VPN/firewall.
Allows you to turn on WiFi in case you need it later on.
Allows easy file/printer sharing through its usb port/sdcard slot.
Connects automatically to the mobile network upon powering on the router (you'll thank me later;)
Costs around the same as a good USB enclosure.
So, pick your poison wisely!
