Thinking this through a couple of options come to mind. 

(1) Get a 4G router as opposed to a dongle, assuming your Firebrick has an available Ethernet interface.  There are routers around that can be put into bridge mode, and in that mode they offer the WAN IP address via DHCP to the router.  That way your Firebrick has direct control of the external IP.

(2) Stick with the dongle. NAT and everything, but use AA L2TP from the Firebrick to get a proper routable IP address, and IPv6.   Then you can choose any 4G service based on price, service availability etc.

I just tried speedtest2.aa.net.uk a few times with my iPad with 4G in the bedroom window upstairs in my bedroom, I got ~7.4 downstream / ~7.0 Mbps upstream on AA Three.

Nice, imagine what you'd get with a decent external antenna.

. . . imagine what you'd get with a decent external antenna.

Knowing the location of the "Weaving Shed", any external metalwork is liable to be a "magnet" for lightening strikes. 

[Ronski]

Yes that could well be a problem.

There is a guy on TBB forums who's in Scotland who has an external antenna, although I don't know where in Scotland. He currently has a thread asking about lightening protection as he wants to mount it on a 2 to 3 meter pole.

Surely a suitable lightning strike system offering very low resistance to earth is the way to.

Hi

I am not an electrician but I would have thought if you had a metal rod longer in length to that of arial and was grounded that lightening strikes should use that due to been highest point

Sorry if it is too simplistic

Many thanks

IIRC from other postings, South Ayrshire.  I'm sure I saw Coylton mentioned once which is a few miles inland from Ayr.

The antenna is positioned at right-angles to the plane of the window, sucker cup attachment on the glass, so that means the main axis of the antenna is pointing directly away from the line of sight. Did a speed test; horrible results = 1.2 Mbps downstream / 0.2 Mbps upstream with https://speedtest2.aa.net.uk.

So a nightmare; either the antenna is horrible or the positioning is indeed a disaster.

I need to retest with the antenna axis vertical, I think.

Any thoughts ?

When I was messing around with the Huawei router I found it very very sensitive to exact antenna orientation.  Based my experience then, you really want a live read out of RSRP while trying different locations or orientation.  Is this still with your 3G dongle, if so then of course it'll be a 3G parameter to be monitored.

It is with the 3G dongle
