Please take the following steps to troubleshoot any wireless links that have sub-optimal performance:
1. Check to see if the devices are running the latest firmware. The latest firmware can be found
2. Check to see if the devices are within the coverage areas of each other and have line of sight to each other.
3. Check to see if the link parameters in use are capable to create a link as estimated by the
(https://tachyon-networks.com/calc.html)
4. If the devices are connected but the connection quality is poor, it could be due to a destructive reflection on the
path. To solve this, try moving your TNA-30x station up or down, or left/right in small increments. Up/down
movements are generally more helpful in these cases assuming the reflection is from the ground plane (e.g. the
ground, nearby rooftops in the path, etc.). Changing the channel may also resolve this issue since different
frequencies will have different channel characteristics.
The TNA-30x (as well as most other PTMP devices operating in the 60GHz band) use a single carrier PHY for
transmitting data. Single carrier PHYs are more susceptible to destructive reflections than some other methods such
as OFDM.
I'm still having trouble with my link, what do I do next?
Please collect the troubleshooting files for both sides of the link you're trying to make, and send them to us at
, along with any other relevant info you might have about your install such as:
1. Link distance
2. Your rain region and
expected RSSI of the link, based on results from the link calculator
3. Wireless speed test results (assuming a link can be made)
4. How you are powering the devices
5. What other accessories (cameras, other radios, etc) are connected to the device, and how they're powered.
6. Relevant environmental details, such as how far off the ground the AP and STA(s) are installed, if there are any
metal structures nearby, large bodies of water, etc.
You can find the link to download a device's troubleshooting file from the menu located under the gear/settings icon in
the web UI, in the upper right corner (see below screenshot under the "Updating firmware" section).
Quick Setup FAQs
Why does the MCS rates of my link seem lower than it should be given a solid RSSI?
You will need to run traffic over your link in order the data rates to modulate to the higher values.
Why doesn't the speedtest cause a spike in traffic on the throughput graph?
The speedtest only sends a very quick burst of packets, so won't have that much of an impact on the overall throughput
graph results.
