How to Lock Your Spark to Specific Network Bands

Katalyst Spark — Setup Guide

Band locking lets you tell your Spark which cellular bands to use. By limiting the device to the strongest bands available in your area, you can improve connection speed, stability, and overall signal quality.


What Is a Band?

Cellular networks broadcast on multiple radio frequencies called bands (also called channels). Different bands offer different tradeoffs between speed and range. Your Spark automatically chooses among all available bands, but if a weaker band keeps being selected, your speeds and reliability can suffer.

Band locking lets you block the weaker bands so your Spark focuses on only the ones that perform best at your location.


Before You Start

You will need to be logged in to your admin panel at 192.168.8.1. If you haven't done this before, see Guide 3 — How to Access Your Admin Panel. You'll also want to know which bands are available in your area — see the Finding Bands in Your Area section at the end of this guide.


💡  Note: Pristine Internet plans utilize the major cellular networks — T-Mobile, AT&T, and Verizon. Refer to the band tables below to identify which bands correspond to your plan. If you are unsure which network your plan uses, please call us and we can let you know.


Step-by-Step Instructions

1

Log in and go to the Internet dashboard.

Connect to your Spark Wi-Fi, open a browser, go to 192.168.8.1, and log in with Username: root and your password (last 8 digits of your Serial Number).

2

Click "Manual Setup" next to the red Disconnect button.

On the Internet dashboard, you'll see a red Disconnect button. Next to it is a Manual Setup button — click that.

The Internet dashboard — your starting point. Click Manual Setup next to the red Disconnect button.

The Cellular Settings page — Manual Setup opens your connection and APN settings.


💡  While you're here — check your APN: The Manual Setup screen also shows your APN (Access Point Name) field. This is the setting that authorizes your device to access the network — think of it as the network's password. Before proceeding to band settings, make sure the APN field is not blank. If it is empty or incorrect, contact Pristine Internet support and we will provide the correct APN for your plan.


3

Scroll to the bottom and click "Advanced."

On the next screen, scroll down to the bottom and click the Advanced button to expand the band locking options.

4

Turn on Band Masking.

Find the Band Masking toggle and turn it on. This enables the band selection controls below it.

5

Choose your mode — Block or Open.

Block mode: any bands you select will be blocked — the Spark will not use them. All other bands remain active. This is the recommended setting. Open mode: any bands you select will be open — the Spark will use only those bands, and all others will be blocked. You can also click Select All in either mode to apply that mode to every band at once.

6

Select your LTE Bands.

Using the band table below, identify which bands correspond to your network. In Block mode, select any LTE bands that are weak or unavailable in your area — those will be blocked and your Spark will only use the remaining bands. In Open mode, select only the bands you want to use.

7

Set your 5G NSA Bands.

If you have good 5G coverage: leave all 5G NSA bands unchecked (in Block mode) so the Spark can use them freely. If your 5G coverage is poor: click Select All in Block mode to block all 5G NSA bands — this forces the Spark to stay on LTE, which is often more stable in areas with weak 5G.

8

Set your 5G SA Bands.

Follow the same logic as step 7: leave unchecked if you have good 5G coverage or click Select All in Block mode to block all 5G SA bands and keep the connection on LTE.

9

Click "Apply."

Click the Apply button to save your settings. Your Spark will reconnect using the updated band configuration.

The band selection screen — choose Block or Open mode, then select individual bands or use Select All.


Common LTE Bands by Network

Use this table to identify which LTE bands correspond to your network. Use cellmapper.net to confirm which specific bands are active on towers near you.


Network

Common LTE Bands

T-Mobile

2, 4, 5, 12, 25, 41, 66, 71

AT&T

2, 4, 5, 12, 14, 17, 30, 66

Verizon

2, 4, 5, 13, 48, 66


Common 5G Bands by Network

Refer to this table when evaluating your 5G coverage and deciding whether to block 5G NSA and SA bands.


Band

Frequency

Type

Primary Networks

n71

600 MHz

Low

T-Mobile, US Cellular

n5

850 MHz

Low

AT&T, Verizon, US Cellular

n2

1900 MHz

Mid / Low

AT&T, Verizon, T-Mobile

n66

1700 / 2100 MHz

Mid

Verizon, AT&T

n41

2.5 GHz

Mid

T-Mobile (Sprint legacy)

n77

3.7 GHz (C-Band)

Mid

Verizon, AT&T


Low band 5G (n71, n5) offers the widest coverage. Mid-band (n41, n77) offers the best balance of speed and range.


Checking Your Signal Quality

After applying band settings, wait a few minutes and then check your signal quality to confirm the results.

Go to: Admin panel → More (or Statistics) → Historical Signal Record

Higher (less negative) values are always better. Check your readings against the tables below:


RSRP  — Reference Signal Received Power (Signal Strength)

Excellent

–65 dBm to –80 dBm

Good

–80 dBm to –90 dBm

Fair / Average

–90 dBm to –100 dBm

Poor

Below –110 dBm


RSRQ  — Reference Signal Received Quality (Signal Quality)

Excellent

–3 dB to –10 dB

Good

–10 dB to –15 dB

Fair / Average

–15 dB to –20 dB

Poor

Below –20 dB


SINR  — Signal to Interference & Noise Ratio (Signal Clarity)

Excellent

20 dB and above

Good

13 dB to 20 dB

Fair / Average

0 dB to 13 dB

Poor

Below 0 dB

Historical Signal Record — check your RSRP, RSRQ, and SINR readings against the tables above.


Aim for Good to Excellent across all three metrics. A few things to keep in mind:

•  It is possible to have a strong RSRP (good signal strength) but a poor RSRQ due to interference or network congestion. Band locking can help by moving the device away from congested bands.

•  A solid everyday connection typically sits around RSRP –95 dBm and RSRQ –12 dB.

•  If RSRQ is consistently below –15 dB, this usually points to interference or network congestion rather than weak signal — adjusting your band selection is the best first step.

•  Keep in mind: even if your RSRQ reads as Poor, your connection may still be performing well. Before making any changes, run a speed test to confirm your actual speeds. If your speeds are acceptable, the signal metrics alone may not require any action.


💡  Tip: In some areas, blocking weak 5G bands and staying on strong LTE bands will give you better and more consistent speeds. Experiment to find what works best at your location.


Finding Bands in Your Area

To find out which cellular bands are active near you, visit cellmapper.net. This site shows real-time cell tower data including network, band, and signal strength by location.

Search for your address and look for towers from your network. The bands listed on those towers are the ones available near you — use that information when deciding which LTE bands to block or open in step 6 above.
