Hints and Tips for Network Connected Software Defined Radios
1) Use the fastest speed possible between your router / switch and SDR connection ideally 1 Gb. And a hard-wired connection is the best choice. Wi-Fi and the use of repeaters add latency and increase chances of a less stable environment.
2) Replace any “Green power saving” Router or Switch or disable all power saving options if available in setup on router or if using a managed switch. (Power saving is going to bite you) usually when you really want to work that rare DX! (these reduce power saving or Green switches and routers tend to at times drop connections when they go into their reduced power state sleep mode, you want a stable connection that is always available when you need it.
3) If your router supports it setup Qos or Bandwidth throttling, you want to make sure your SDR and controlling computer receive the highest amount of your bandwidth, there are many ways to setup Qos or bandwidth throttling, and it varies by manufacture and at times models of routers. Look at your user manual or online with your manufacture to see if Qos is available. By setting up a Qos plan you can limit the amount of bandwidth other devices are using giving them either a set state or percentage of bandwidth, and set your SDR and Computer to receive the greatest amount available, so devices like your kids streaming movies or gaming receives less than your SDR and rig controlling computer when you’re operating.

4) Keep your routers firmware updated, many routers offer the ability to update their firmware, which can close security loop holes and bring new options and stability to your router, check your manufactures website to see if a newer firmware option is available (backup your current configuration as a precaution before applying the new firmware).
5) If your router is using DHCP Then assign a “static DHCP” either by IP address or MAC address. This will ensure your SDR and Computer always get the same IP address from your DHCP enabled router and can reduce oddities and loss of connections, Especially when using other programs that are looking for your Rig at a specific network address.

6) If you make changes to your network router/switch reboot you SDR and Computer network changes can cause your SDR and controlling computer to hang at times particularly if they involve changes in DHCP, IP address assignments, Gateways, Subnets or even DNS servers.
7) With remote operations you may find that if you assign a faster DNS to your router you may get better connectivity, there are many optional DNS servers which can be added. One that I like and have found works well not only for better connections but also security is the IBM QUAD 9 DNS. Always add the faster of the DNS servers you use first.

8) Check your routers suggested bandwidth or supported devices connection limits, routers have processors some are better than others at sustaining good connections with many devices while cheap ones may struggle keeping 3 or devices connected and sharing data properly. A House full of devices, Smartphones, computers, tablets, smart TV, Smart devices like thermostats etc. and now adding your SDR may have topped out the processors ability to properly work. Your using a higher end transceiver with remote capabilities why limit this with a crappy cheap router or WIFI device.
9) Antivirus programs- Many Antivirus programs can cause issues with connection of your SDR, some may even attempt to block or firewall SDR applications, Check your A?V and see if it has blocked or attempting to Block any connections or ports that are need for communication between your SDR and your computer, Add exceptions if necessary. An Antivirus product I have been using and recommend is Emsisoft Antivirus Antimalware - PM me if you want more info or a trial of this product as my company is a registered reseller.
10) The Firewall- Check your operating systems firewall, at times you certain applications can be blocked or firewalled resulting in connection issues with your SDR, again add exception rules if that is the case.
If your still having issues leave a comment or message , many of us have been thru oddities before and can certainly make suggestions or provide a hand.
