How to update firmware on UHF-R or Axient (AXT) hardware
Likely cause: These are discontinued lines with no auto-update; WWB6's Firmware Update Manager is the supported path and mixed firmware between networked components causes discovery/control failures.

Intermittent audio dropouts on a UHF-R (UR4S/UR4D) channel
Likely cause: Most UHF-R dropouts are RF coordination or antenna problems, not a faulty radio.

Multiple UHF-R/Axient systems interfere with each other when run together
Likely cause: UHF-R offers up to 2,400 selectable frequencies but only a compatible subset is intermod-free together; WWB6/AXT600 calculates a mutually compatible set.

Ordered wrong band / transmitter and receiver will not tune to each other
Likely cause: These systems are analog and band-locked to a hardware RF block; a TX and RX in different band letters physically cannot land on a common frequency, so no scan or sync will pair them.

Receivers do not appear in Wireless Workbench 6 (WWB6)
Likely cause: UHF-R network discovery is layer-2/subnet dependent — WWB6 only finds receivers on the same subnet as the computer.
- Step-by-step fixGet the fix →
Transmitter and receiver won't link / new frequency deployed on receiver but TX still on old freq
Likely cause: The UHF-R/Axient IR port transmits group, channel and TX parameters to the transmitter; a completed IR sync guarantees the TX and RX are on the identical frequency, which is the only reliable way to pair after re-deploying a frequency.

Using UHF-R transmitters with an Axient AXT400 receiver (mixed fleet)
Likely cause: Shure designed Axient to protect the UHF-R investment, so AXT400 tunes the same UHF band and accepts UHF-R radios; the advanced Axient features simply degrade gracefully to standard operation with a legacy transmitter.

What ShowLink and Frequency Diversity do on Axient (AXT) and how to enable them
Likely cause: These are the defining Axient-analog features: ShowLink gives remote TX control the UHF-R line lacks, and Frequency Diversity provides true RF redundancy (two independent frequencies) so a hit on one frequency does not drop the audio.
