Hello,
Im running a 2DX using 12.1 alpha.
It is very stable and will run for days with a direct connection to the PC.
If i try running it through my router which is mikrotik hAC 2 the software loses connection after some time.
Same results for wired ethernet or wifi on same router.
Does anyone run stable through a mikrotik router?
Do you have a suggestion for a different router or possibly a settings change in the router configuration?

Thank you,
Mike

Hello
The router indeed is the issue, possible solutions are there – github.com/ExpertSDR3/ExpertSDR3-BUG-TRACKER/discussions/118
The most reliable connection is the direct connection between TRX and PC, or it should be a trusted router.

Thank you for the reply.
I did change the router to Asus GS-AX3000 and now the connection is flawless.
Still, better latency with the direct connection to PC though.
Overall I am very happy with the performance of the 2DX.

Hello Ron.
There are hundreds of routers, and we cannot check all of them, thus such a list doesn't exist.

HIGHLY ADVISE NOT GETTING A DAMN SWITCH or ROUTER THAT IS A GREEN POWER MODEL>>> Also get a 1GB switch / Router, it will step down to the 100Meg that the EE rigs use and automatically connect up to the 1GB other items use. Treat your network , Radios and other items like there in a Business environment network configuration- and you'll be better off.

If you do have a Green switch / Router and it is a MANGED switch TURN off the Green/ Power saver option, Managed switches are great, but probably overkill for most users when it comes to configuration of them, if managed give priority to your RADIO and Computer

I also look for switches and routers which have INTERNAL POWER connections- the type where the AC plug is directly on the unit itself instead of using a wall wart- you'd be surprised at times the noise these cheap wall warts produce and now you're injecting that crap on your network with a radio connection it' can act like one big antenna!

If its a Business class series router/switch your chances are very good that performs issues will be minimal
If its a basic home user/consumer grade router/switch then your chances of having problems has GONE UP!

Thanks

Sure John
I'm talking about the switches that do not use a wall-wart, AC to DC external power adapter . Instead power from AC mains is plugged directly into the unit.
