The server may be currently offline, or there may be a connection issue between your openSPOT3 and the
server. You can try using another server, or enable the
Override DHCP DNS servers setting.
Also check if the server password is set correctly (in case there's a server password), and that your connector
settings are valid (example: if there's a callsign setting, make sure your callsign is valid, if there's a DMR/CCS7 or
NXDN® ID setting, make sure your ID is valid for your callsign).
If you want to connect to the BrandMeister network, and the openSPOT3 won't connect to any BrandMeister
server, then make sure you use the hotspot security password you've set on your
BrandMeister SelfCare page. If
hotspot security is turned off on your BrandMeister SelfCare page, then you have to use the default server
password, which is passw0rd. The UK server uses the default password passw1rd.
There are dropouts in incoming calls, voice is stuttering
Make sure you use a server nearest to your location to avoid network dropouts and high latency. Please keep in
mind, that packet loss and high latency can occur in VoIP (Voice over IP) streams even if you have a really high
quality network connection.
Check the dejitter queue graph on the Status page for invalid seqnum errors. These indicate that the openSPOT3
does not receive all network packets so there are missing parts from the incoming call's stream.
If there are no invalid seqnum errors, but the dejitter queue graph shows that the queue gets empty during a call,
then you can try increasing the dejitter queue length at the
Network settings section.
Try to set another Wi-Fi channel in your Wi-Fi network (see the next troubleshooting entry for more info). The
currently used one may be overcrowded, which you may not notice during web browsing, as the web uses a
protocol which resend missing data frames, but this can't be done in real time VoIP streams so the packet loss
issue becomes instantly noticable.
Wi-Fi disconnects (blue status LED) or internet connection errors (red/blue
status LED)
Try to set another Wi-Fi channel in your Wi-Fi network. The currently used one may be overcrowded. It is
advisable to use Wi-Fi
channels 1, 6 or 11 . Do not use the others as they only cause more interference. Also try
placing the openSPOT3 closer to your Wi-Fi router / access point.
Color code mismatch warnings on the web interface
Make sure the color code programmed for your radio's current channel is matching the openSPOT3's color code . If
they match, then probably there's an offset between the radio's TX frequency and the openSPOT3's RX
frequency. Please try to use
AutoCal , or manually enter different frequencies in +-100 Hz steps at the RX offset
on the Modem page.
The device does not upgrade the firmware
Note that you have to plug the openSPOT3 into a USB power supply, otherwise the bootloader can't start and the
firmware will not be upgraded. This also applies to overnight automatic firmware upgrades.
The device can't check firmware upgrades, it shows retrying
Make sure the NTP, HTTP and HTTPS outgoing traffic is not disabled in your router's firewall. You can also try
turning the
Use DHCP server if available option off.
Upgrade downloads are slow
