The Netgear Orbi 4GX LBK1220 router and MESH satellite can deliver either NBN fixed or Telstra 4GX mobile data to a small home or apartment at Wi-Fi AC1200 speeds or via 1GBps Ethernet. Or it can act as a fall-back to 4GX if NBN is down.
Our test home is in a Telstra 3-bar reception area, and the trial Telstra SIM had expired by the time we could test it. Fear not, although you can only buy it from Telstra, it works equally well on Telstra MVNOs like Boost or Woolworths with access to band 28 (700MHz).
These tests are on NBN 100Mbps from Aussie Broadband and Boost mobile data (most Telstra MVNOs have capped data download speeds at 100Mbps so it may be capable of slightly higher speeds).
Let’s move on to the tests for the Netgear Orbi 4GX LBK1220
Test #1 – 4GX Reception performance
Let’s start with Telstra 4GX speed claims. Telstra state (the capitals are its)
THE TELSTRA MOBILE NETWORK OFFERS 4GX IN ALL CAPITAL CBDS AND SELECTED SUBURBAN AND REGIONAL AREAS AND IS PROGRESSIVELY ROLLING OUT TO MORE PLACES. IN OTHER COVERAGE AREAS AROUND AUSTRALIA, YOU’LL AUTOMATICALLY SWITCH TO OUR FASTEST AVAILABLE 4G OR 3G. CHECK COVERAGE HERE.
In 4GX areas, typical download speeds are
2-75Mbps for 4GX category 4 devices
2-100Mbps for 4GX category 6 devices
5-150Mbps for 4GX category 9 devices
2-50Mbps for 4G areas
Using a Boost sim and a Samsung Galaxy S20 Ultra 5G (and sitting beside a 4GX tower) gives a maximum of 100Mbps download (capped) and 20Mbps upload. The reality is that even if you have the best 4GX reception Orbi cannot achieve much more than that.
The Orbi app has a connection status tab that shows mobile broadband signal strength (Reference Signal Received Power or RSRP). In our case, RSRP is between -97dBm and -115dBm – almostuseless for mobile data.
The moral is to check that you have adequate Telstra 4GX (band 28) reception before considering the Orbi (or any other 4GX modem) instead of a fixed NBN router. Ideally, the RSRP should be between -30 and -80dBm (lower is better).
You can download Network Cell Info Lite for Android from Google Play to check. See the screenshot below.
If you have lousy Telstra reception (as we do), the best you can expect is probably 10Mbps download, and 10Mbps upload with ping times from 40ms. This is enough to do email, browsing, audio streaming. But don’t expect to share that with too many devices on the Orbi Home Network.
Test #3 – how it performs in a 280m2 area.
All manufacturers make theoretical claims about coverage, so we try to convert the theory to reality.
The reality is that coverage is about 2 x 13-metre circles overlapping by 3m each – about 20-metres x 10 metres in total.
That equates with the approximate 10-metre diameter circular Wi-Fi 5Ghz transmission range that the Orbi uses for MESH backhaul. The ideal placement is about 5-7 metres apart inside the 5Ghz overlap with the router and Satellite servicing different home areas.
We set up the router first (no satellite)
Distance from router (meters)
Signal strength %/-dBm
866 – excellent
390 – good
260 – good
45 – unusable
Then the Satellite at 7m from the router (line-of-sight)
Distance from Satellite (meters)
Signal strength %/-dBm
430 – about maximum*
360 – good
260 – good
200 – good
What this means
The router has an overall transmission distance of a 10m diameter circle. By itself, it is a competent AC1200 dual-band (2.4GHz 400 and 5Ghz 866Mbps) router. Its antennas are not as sensitive as the traditional Orbi tri-band Wi-Fi AC and AX MESH systems.
* Once set-up the Satellite uses 5GHz backhaul to the router. In this case, it leaves about 430Mbps data transfer speed. This is the same as any dual-band MESH.
Regrettably, there is no satellite Ethernet backhaul.
Test #3 Mobile data costs
For ease of comparison, most NBN providers offer 12Mpbs ($60), 50 ($80) and 100 ($100) monthly plans with unlimited data and no-lock in. Your minimum commitment is $60-100 per month (or $720-1200 per annum) for all the data you can eat. Routers range from $150 for an AC1600 dual-band to $699 for the fastest ASUS AX11000 tri-band.
Mobile broadband costs are somewhere between $.38 and $3 per by the GB. Depending on the Telco or MVNO unused data may be lost; rolled over to the next month and expires in that month (*); or in some cases data banked, e.g., Woolworths has 200GB data bank rollover for 28-day pre-paid.
Just be careful that any Telstra MVNO you choose has 4GX LTE band 28 and remember only Telstra has uncapped speeds that may get you a few more Mbps.
All prices below exclude any time-specific marketing promotions.
Telstra has a pre-paid mobile data-only plan (bunded with this device) that costs
Included data (GB)
Price per GB
Note that the price per GB assumes that you use all the data each month – most don’t, and you are paying a far higher average GB rate, even with a 30-day rollover and expiry. Our advice is to go for the lowest data plan and upgrade if you find you need more.
Boost has pre-paid plans too
Included data (GB)
Price per GB
So, if you are a heavy user, then NBN is your best alternative. Note that Orbi supports WAN (Ethernet) connections to an NBN Gateway.
$399 from Telstra ($33.25/12mths or $16.62/24-months) plus a data plan from Telstra.

Buy the Netgear Orbi 4GX LBK1220 for 4G fall back.
Netgear/Orbi is good quality from a good company. This is an entry-level dual-band MESH system suitable for a small apartment where you can get the router and Satellite working in 5-7metre line-of-sight, and you can get decent 4GX speeds. It probably can support 10-20 devices.
Its unique selling proposition is 4GX fall back from NBN or for itinerant renters. As we have shown, data speeds depend solely on 4GX reception signal strength. And mobile data is not cheap, highly variable and often wasted.
We find it hard to recommend it as a standalone AC1200 dual-band MESH router as there are many faster tri-band MESH routers for not much more.
And one final caveat. Telstra obviously wants you to buy it on a 12–24-month plan where you commit to $399 for the router and $15-75 a month for data. That is a significant and fixed-term commitment, especially as there are lower cost outright purchases 4GX Modem/routers and third-party mobile data providers with no lock-in plans.
