Although you mentioned you were in a strong signal zone (did you mean strong adjacent interfering signals?). Keep in mind most data that the radio sends/receives are UDP, and UDP packets are connectionless. In other words, if the packet doesnt make it to your computer for whatever reason, the software doesn't care and it doesn't try to resend it. That's one of the trade-offs for speed. UDP packets are faster because your computer doesn't have to establish a new connection and send an acknowledgement packet (ACK packet) for every UDP packet it receives.
Hi Robbie, 12ft away from the router. Once your on WiFi its hard to go back to a piece of wire I can tell you. Great to have your expertise here too with low down on UDP & ACK explanation. I will keep trying in different locations and lets face it WiFi is everywhere around us like soup ! ..... So what is really happening in the Ghz world is beyond me. Although PC & Router are dual band.
Yeah the FlexRadio guys will definitely have a much better answer than me, they know their product better than I do (I'm just a end-user like you are).
Although I can through this bit of knowledge out there as well. Your dual-band router will only use one band at a time to your computer, and it will also step down the connection speed if the connection quality degrades. I know how to find the connection speed on a Mac, but don't recall where to get the *true* connection speed information on a Windows box. So if it seems like sometimes it works better than other times, that could be what is happening (but this is just a guess). Any type of ambient interference (led/flourescent lights, wired smoke alarms, etc) can cause the speed to step down. Same things that can cause intereference with ham reception.
And of course, it isn't just speed (I don't think the 6000 needs very much bandwidth), but it sends a continuous stream of data, so any momentary interruptions could cause an impact. This sorta goes back to the buffering topic (kinda).
That's fine information Robbie, all good think tank stuff..... So lets wait and see what's cookin ! To date I left the subject on the backburner in respect of the quantum tasks ahead and awesome progress by the whole Flex team. My fetish for playing with the absolute cutting edge can wait for the roadmap to become rolled out. No point screaming about the roads when they ain't been built yet....
Increasing you UDP buffers will probably not make a lot of difference in the performance. The default size of the UDP buffer is probably large enough to handle the data throughput for your wi-fi connection.
You did not indicate what speed your wi-fi router is running at, but looks like you have is fairly "loaded up" from a SmartSDR perspective since you are running CAT, DAX and a full compliment of pan adapters.
So if your wireless is running at a low speed, like 12 mbps (which is really 6 mbps maximum theoretical throughput - remember wi-fi is half duplex), you are over subscribed and packets will be dropped. No amount of buffering will fix this problem.
So the first thing you have to do is determine your actual connect speed
Also even if you are in a strong signal zone, multi-pathing and reflections can also degrade throughput performance.
The bottom line is that wi-fi while convenient and in a lot of cases ubiquitous, it is not the preferred method for connecting the 6000 to the PC client.
Some of the solutions employed for the Internet today are just not viable -- for example with video, your client just buffers a substantial amount of traffic before starting the video. Yes we could do this, but how would you ever transmit if your receive audio was always 30 seconds in the past? The video solution on YouTube also understands that you are viewing finite content. For example, if you go to watch a 60-second video that will stream at 1Mbps and you can only get ~500kpbs rates off your connection, YouTube does the math and realizes that if it buffers for 30-seconds, it can start the video. You will have "caught up" by the end of the video, but it no longer matters. Listening to a radio is an "infinite content" problem because you are not likely to stop listening at any close point in the future.
The video solution on Netflix is totally different. Because their content is longer, they measure your stream rate and pick a certain bandwidth of video that will work (they have each show stored in a number of different streaming rates). If you fail to meet your delivery goals on the content, they just bump down to a lower streaming rate. Perhaps you've seen this if you use Netflix (I generally stop the video and restart, but I suspect I'm in the minority here). We can do things like this -- for example slow the panadapter update rate if there is network congestion. This is really the key part of the remote networking effort -- to make all this "just work" so you don't have to fool with a bunch of knobs to make everything work right.
All of this is why we've focused on minimizing all the traffic required for each stream/display we will send over the Internet. We're working the same details on waterfall now and again we've gone to great lengths to minimize the network traffic so that we will be properly positioned for full remote that works well.
Remoting over the Internet without a computer must be possible. I am the owner of an Icom 7800 and recently they upgraded their firmware which includes it built-in CODECS for both transmit and receive audio. Also the radio connects directly the Internet. It is the most fabulous remoting software I have yet to use. So I know this can be done and, hopefully, Flex will strive to make the 6000 series equally stand-alone for Internet remoting. I use the 6500 for remote panoramic display and the 7800 for the actual remoting.
try with the following steps,
1.)Reset the wireless router by using the power switch on it or by unplugging it and plugging it back in.
2.)Place the wireless router in an ideal location. The higher it is, the better, but don't put it near metal objects.
3.)Get as close as possible to the router with whatever device you're trying to connect.
4.)Keep the router and your connecting device away from other electronics. You should especially keep away from phones, fax machines and microwaves. etc.,
5.)Adjust the Wifi antenna if it has one.
6.)Change the router's channel, especially if other wireless routers are nearby.Following these steps would give you stable internet connection and also increased speed in connection. You can check your internet speed from http://www.scanmyspeed.com/ before and after following these steps.
Looking forward to the "network radio". I've got a 6 mbit upstream with my provider, so I can't wait!
