New Gear: Ubiquiti Unifi 5G Backup

Ubquiti Unifi 5G BackupApologies for the lengthy preamble. Back in 2001 when we moved into this house we started with Comcast cable modem internet access that delivered 5/1 mbps. We were committed to Comcast for cable TV since we were a Tivo household. Tivo DVRs leveraged cable and the Cable Card decryption scheme.

It also happens that Comcast’s internet access was not very reliable. That caused me to get a DSL service installed as a backup. The DSL service provided by Sprint was modest. We are some 11,400 feet from the nearest central office, which meant that 1.5 Mbps / 768 kbps was the best we could achieve.

Over a number of years, Comcast’s cable modem service got both faster and (somewhat) more reliable. Still, I retained the relatively pokey DSL service as a backup. After Hurricane Ike in 2008 I felt vindicated in that choice. Throughout and after that terrible storm we had sustained phone and internet access via that DSL service. In contrast, Comcast was out for a month.

There came a time when I realized that I had not used the DSL in over a year. And 4G wireless broadband had become available, so I could tether to a phone in a pinch. That combination supported ending the DSL service, which suffered declining cost/performance.

All that is back-story. In all that time, we never had a “dual-WAN” arrangement. Failover between the ISPs was manual. Typically, repatch the WAN port of the router to the desired modem, then load a different WAN configuration. Not difficult. But manual.

Well, no longer! Last week I took delivery of the new Ubiquiti Unifi 5G Backup device. Newly introduced for just $99 this wee magic wand promises an affordable, automatic backup to a 5G wireless service. It’s not locked to any carrier. At the outset it works with AT&T, T-Mobile, and presumably their MVNOs.

T-Mobile 5G: An Experiment with Fixed Wireless Internet Access

t-mobile-gateway-v4-frontIn the next few weeks we’ll crest the first anniversary of Hurricane Beryl, which had quite an impact hereabouts. In the storm we lost power for a less than two days. However, our Comcast/Xfinity internet access was out for a week. As someone who works full-time from a home office, that was a problem for me. As a contract IT worker, no internet access means no money. No buénno.

My laptop, a Lenovo X1 Carbon Gen7 from 2019, has the optional 4G mobile data access module. It’s part of our Mint Mobile family plan. So, at some level I can be online with just the laptop. That provides a minimal level of productivity.

Similarly, I can tether my desktop and perhaps one or two small devices to my mobile phone. That’s ok for an afternoon, but not a good solution for a week or more.

The 4G speed test on the laptop screen reflects 4G LTE access, not 5G. Also, Mint Mobile data rates are often lower than T-Mobile’s own clients. Even though T-Mobile now owns Mint, the MVNO customers are given lower priority on the network.

Then it occurred to me that all the mobile carriers had been promoting fixed wireless service in the neighborhood. In post-Beryl Houston, power was out at our home, but not too far away there was a T-Mobile store that was open for business as usual. They had a 5G fixed wireless devices for $0 with $60/month and no contract term. It seemed like potentially a good solution. At least, there was little to risk in trying it on for size.

T-Mobile: Breaking-up is very hard to do!

We have used T-Mobile for our mobile phones since 2005. Over the course of 2021 I grew frustrated With T-Mobile. They had become too costly. There were no deals for existing customers. As our monthly mobile bill approached $200 I felt there must be a better way.

In December I decided to make a change. In truth, I’d made this determination in the early summer, but had to wait until the end of the 24 month promo deal associated with our current pair of Pixel 4 phones. That agreement ended on December 13th.

December 18, 2022

Free of the encumbrance of the purchase arrangement, I ported our two active numbers to Mint Mobile on December 18th.

Mint vs TMobile

Mint Mobile is a MVNO that offers well-priced prepaid service on T-Mobile’s network. So, I was confident that the experience of the service would be unchanged. We’d just cut our monthly cost.

I took advantage of a holiday promo, paying $240 for 6 months of 3 lines, where each line had unlimited voice & text, with 15 GB of data. 15GB is more than we actually need, but the price was good and I didn’t want to feel constrained.

The third SIM was for my Lenovo X1 Carbon laptop, which has a built-in LTE radio. For the past couple of years the laptop serves as a backup to our Comcast Business Class service. Mint doesn’t actually offer data-only (aka tablet) SIMs. I just got an extra voice line and put the SIM in my laptop.

The cost of the 6 month term was very appealing given that we had been paying T-Mobile $185 every month!

In just a few days I received the SIM kits. The porting process went smoothly, taking about 30 minutes for each of our phones. The SIM card for the laptop was a new number. It just seemed to work. There were no issues at all with the transition to Mint Mobile.

Offline Today

From 3am this morning our home network has been offline. This was expected. Comcast, our primary access provider, was quite good about notifying us of a planned fiber upgrade. The process has been taking areas of the neighborhood offline briefly…
