Starlink Mini as a failover

I live pretty rural and starlink has been worth the price over the last few years. When you compare it to dialup or hughesnet or viasat, it just works.

I have a GL.iNet travel router. When I am not travel, it connects to the router's second WAN port. If my main internet goes down, it takes me 30 seconds to tether my phone and failover manually. My carrier detects and throttles hotspot traffic by measuring packets TTL, so I tweaks the router's iptables to dodge that. Typically I get over 400 Mbps.

From time to time I get the itch to improve my home network uptime, and I have to keep reminding myself that the current setup is fine.

I also do this. Xfinity went out for a few hours earlier this month and Unifi failed over almost instantly, and within minutes we had high speed internet once I upgraded us. The standby mode would have been plenty for basic web browsing, too.

$5/mo for pretty guaranteed connectivity, plus being able to take it around with me on travels is pretty awesome.

A mobile failover would be cheaper and would give you better connectivity in heavy rain.

A 4G dongle can be purchased for $15, rather than $200 for a Starlink Mini. Then, let's say your main internet source fails and you need to actually use the backup plan beyond the standby amount of 0.5 Mbps. That will cost you a minimum of $50 for Starlink, versus roughly $25 for a month of unlimited cell service. As for standby costs, you can find phone plans for $5 per month tat give a small amount of fast data, as opposed to Starlink's unlimited amount of slow data.

But of course this only works for areas that actually have cell service.

Using a 4g/5g router is much easier and probably cheaper/power efficient.

Depending on your area you don't even need an external one. A simple 4g dongle would do.

I really REALLY want this, but I just can't give money to Musk.

I prefer having a 2nd wired connection as my backup. The satellite connection has some clear benefits, but it's still going to outer space. A DOCSIS failover won't suffer from rain fade or a something landing on the antenna.

If I've got a situation so bad it takes out both of my connections I've probably got bigger things to deal with than internet access.

The buried fiber getting cut by is really the only thing that kills the connection. Fiber can go for a long time without power from the local grid infrastructure. My cable provider has a mostly orthogonal failure mode (goes down like clockwork with the grid).

TIL standby mode. Is that enough to operate a remote webcam? Not real time video feed but say uploading a photo every 1 minute or so

Man, that 500kbit/s is quite generous for that price, can easily be used to access CCTV cameras in remote areas. I currently use LTE for that and it's 10 eur for 15GB data cap per month for that use case

I can't give money to Musk. I just can't. OP doesn't live in the US, so maybe they don't feel this quite as acutely, but it's difficult to name someone who has done quite so much long-term damage to the US in such a short time.

Every so often I do the numbers on a backup Internet connection and decide that it's not worth it, but understand that it is useful for peace of mind reasons. My Internet is just too reliable. When I'm out of contract with my current provider I'll need to reconsider this as the supplier I'm likely to move to has no obvious/simple/integrated backup option.

tl;dr FTTP. A single outage event in 16 months, lasted 40 minutes, whilst asleep.

I'm in the UK and have FTTP through BT. Way back when I also purchased the 4G backup option (Hybrid Connect) that comes with this service. That's an extra £7.50/mo when taken as part of the usual 24-month contract. It's simple to setup and doesn't require any specific maintenance.

Looking back at the logs it's clear (from an actual usage perspective) it's not been worth the £7.50/mo I've been paying for it, but I'll admit it helped give me peace of mind when I was on-call for work so it is easy to justify.

The BT supplied router (which is required if you want to use their 4G backup hardware) keeps a log of "Resilience events".

In the 16 months I've had FTTP it has had exactly one "resilience event". A 40m11s outage that started at 00:20:05 on 28/11/2025. I was unaware of this outage as I was asleep.

It was really useful when I moved house though. I was in the middle of a 24-month contract with BT at my old address so I ported my contract to my new address. This meant they had to come round and install FTTP at the new property, which they couldn't do for a couple of weeks, so I was without home Internet for these two weeks.

Luckily the 4G "Hybrid Connect" backup device wasn't geo-locked (or if it was maybe BT overlooked it given there was an outstanding "Moving house" order on the account) and so it worked perfectly for the ~2 weeks between moving in and FTTP being installed. If this hadn't worked then a temporary 4G router would have worked just as well.

I had a bunch of "resilience events" for this period (it wasn't one continuous event as I was moving/restarting the broadband router for various reasons). During those 13 days the logs show 163GB download and 25GB upload. That's an average of ~150KBps (note the capital B there, in bits-per-second it is ~1.1Mbps) download.

In the 26 months prior to moving (where I was on ~75Mbps FTTC with BT) I had 3 "resilience events". 17m36s, 47m7s, 31m22s. All between midnight and 4am where I wouldn't have noticed, these were also within 1 month of each other, the other 25 months had no problems at all. None.

When my current contract comes to an end I'll move to a different supplier (probably Community Fibre as I can get symmetric 5Gbps for less than I'm paying BT for 1Gbps/120Mbps) and then not worry about a backup. If it is less reliable then I'll look for a solution then.

My current backup is simply to hotspot on my mobile with 5G (good signal here). Doesn't help the others in the house but they can fend for themselves. Neighbours have different suppliers or technologies (DOCSIS vs FTTP) so swapping wifi details would also be an option.

As others have pointed out, a local power-cut that takes out of the FTTP cabinet could easily take out the local 4G/5G masts making a 4G backup solution useless. If this happens I can just take my laptop to a nearby cafe or the co-working space I use. That kind of outage is very rare though round here.

Then again with the sums involved (under £10/month extra) it may just be easier (for peace of mind again) to just plump for something that doesn't really make amazing financial sense as it's just the cost of a pint or two a month.
