WiFi Requirements and Performance with Maestro
We've been receiving some questions about WiFi networks and Maestro so I want to explain some of the requirements for Maestro. Most of the applications you use over WiFi do not require low latency -- the exception would be a VoIP or video app like FaceTime. When you watch YouTube or Netflix, for example, you need the application to "keep up" with the speed of the video, but the application has been programmed to know that you as a consumer understand that buffering is a necessary part of watching the video. When you launch the video, the application buffers at as fast a rate as it can, measures that rate and then starts the video only when it is assured that it can keep up through the end of the program. This results in a brief start-up period while the buffering occurs.
For Maestro, we assume that there is a high likelihood that you will actually want to communicate with the folks on the other end of the path. They're not going to be tolerant of a 10-second buffering period nor are you. How weird would it to be to call CQ and then hear someone respond 5-seconds into your conversation with another ham? Because of this, we buffer very little and expect that the WiFi router will be able to provide good streaming service. In other words a steady stream of packets with low loss and data that is not bursty.
We've tried a number of routers and have found that some work much better than others. The ones we've had the best success with are the newer 5GHz AC3100/AC3200 etc routers. We've also had good luck with the AC1900 routers. When at hamfests, we've had issues with all of the other vendors and convention centers on 2.4GHz so we often stay away from that band. Unless you run VoIP, FaceTime, etc. over your WiFi router, you probably have little visibility into whether it offers good coverage or not. What seems like a slow site or slow Internet could be your WiFi losing a large number of packets and having to resend them. So with all this in mind, here are some recommendations:

What seems like a slow site or slow Internet could be your WiFi losing a large number of packets and having to resend them. So with all this in mind, here are some recommendations:
If you experience WiFi issues:
- Check the performance of your router or look up a review to see how it should typically perform. Routers that advertise they are for "gaming" are best suited to a low latency environment since this is a requirement of gaming
- Check your Wifi channels to ensure they are not shared with another router. Often times everyone in a neighborhood will end up on a default channel on 2.4GHz like channel 6. Scan the neighborhood and be sure you are not on a channel with others if possible.
- Switch to using 5GHz if your area is crowded on 2.4GHz.
- Check your settings in the router to ensure they are setup for "gaming" or other low latency applications. This can include disabling features like packet coalescing that hold packets to be sent only after larger quantities of data are received at the router. On the newer routers we've had good luck taking all the defaults.
- Check forums on your router to see if there are specific settings that could help with any issues you encounter
- Check reviews for the routers from reputable sources to verify if the router performs well. Some companies rush to get their router to market first and have performance issues on specific bands/etc. Often the reviews report these problems
- If possible, use a router that has both 5GHz and 2.4GHz so that you can use whichever is less congested in your area
- If you use both 5G and 2.4G, name the SSIDs differently in the router so that you can be aware of which you are connecting to. For example, name one "MYROUTER" and the other "MYROUTER_5G"
- Read the manual looking at all the options to ensure that you have the lowest latency settings enabled.

My Maestro is due here this afternoon sometime. Thanks!
Now, onto my points. I'm hoping for a smooth transition to Maestro as I've been using an 8" Lenovo Windows tablet running SSDR for several months and have generally found what works and what doesn't. I'm hoping that experience will prove to be useful guidance for setting up my Maestro.
One clear vulnerability I've seen using 2.4 GHz. WI-Fi is interference with Bluetooth which uses the same frequencies. It seems this will be particularly troublesome if a Bluetooth headset is used with Maestro at the same time it's using 2.4GHz WI-Fi.
Another item, I've had great luck using the tablet & SSDR over WI-Fi at a couple of McDonald's restaurants using SoftEther as the VPN server at home and the stock, Windows L2TP/IPSec PSK function in the tablet.
In another thread it was asked if there would be provision in Maestro for responding to the splash screen that McDonald's presents before providing access to WI-Fi. I've never seen the answer to this.
I also use cellular hotspot tethering using my cell phone over Cricket Wireless, which is now an AT&T subsidiary and uses the AT&T cellular network. This doesn't work very well as, I think, the data is routed in such a way so that they can measure my usage. The resulting ping times rise to over 100 MSec. In this environment the RX audio is heard but the spectrum and waterfall information never show in the display. I only see the background.
Using a Straight Talk cellular hotspot, their model specifically selected to run on Verizon's network, the ping times fall to around 65Msec. and things work out a lot better with full audio & display. The Straight Talk model that runs on AT&T suffered the same fate as my cell phone.
I hope these tidbits are useful to others.

Are there some brand/model numbers we can buy that you know works well?

These are not cheap that he mentions, but hot in performance.

My router is a Peplink Balance 20. I've become so comfortable with its setup screens & the way it works, I'm reluctant to take it out in favor of the Asus or the Arris routing functions.
UPS just arrived with my Maestro. BYE!

My experience with wifi routers (going back as long as there were consumer wifi routers) tells me they are some of the most perishable of equipment. I am not sure I have ever had one last more than 3 years and almost all didn't survive 2 years. It could be purely a matter of lightning/static fields/whatever but they die more often than any other device in my network.
How can you justify 300 USD and higher investments in these? Is there performance, vis-a-vis the 110 buck D-Link router mentioned above really worth a 3+x investment?

On another note, Flex 6300 upstairs, maestro in living room. It took five minutes to install the legs & another five to start it up. So far it's perfection on 5GHz Wi-Fi.
Are you guys telling me that the wifi requirements for the Maestro are going to be greater than my Laptop?

But remember the old saying "I don't want to know how the clock works, I just want to know what time it is?" I suspect many of us just want to know WHAT TO BUY (very specifically!) so we can go to our favorite seller, click on it, pay for it, and hook it up when it arrives. <GGG>.
You have a gold mine of research experience to share so why not give us your 3 favorite routers by specific model number? (And which ones to avoid by specific model number. )
I want to run my new Maestro when it arrives, not waste time replicating your tedious research. Be brave Steve! Go ahead tell us.
TNX. -Dave.
Please refer to Steve's post above:
I hesitate to recommend specific routers. For my own use, I go to PC Magazine and those type places and read their reviews to make up my mind. I recently had to buy one in a pinch at a local big-box retailer and I just looked up everything they had in the store online for reviews and saw that a couple they had were "no-nos" according to the reviews. I bought one that got 4.5 stars in a PC Mag review and it performed flawlessly.
C'mon, Tim. That why I wrote "I don't want to know how the clock works, I just want to know what time it is?"
What is so complicated about this? This is not a school assignment --- I don't want to know where to go for more information. Just make some recommendations with a simple caveat and move on...
I regularly use a laptop from my garage and various other places in the house to access my 6700 with no problems at all. I normally have 1-2 panadapters and 2-3 slices open at the same time and still no problems. For my eyesight the screen is just a tad too small for anything more than 2 panadapters. I use a LG wireless headset for communications while using the laptop. I've heard bluetooth can interfere with 2.4Ghz wifi, but I haven't seen that either. My house isn't very large so for the most part I'm usually not more than say 60-80 feet from my access point. The only time I have had trouble is when my wife gets on her tablet via wifi and starts playing some youtube video..... Since she doesn't get on very often, I usually let her win and have at it for a while.
As far as latency goes, I do experience it, but it isn't all that bad. It is especially noticeable when I'm on a net or talking with a group of friends. I have a tendency to double with others because I don't immediately hear someone transmitting due to the latency and I occasionally will talk over top of them.
From what I'm hearing though, my old Linksys routers may not work very well with the Maestro. I'm going to wait and see. I have several of these old routers and I can't tell you how happy I've been with them. The ones marked with V1 thru V3 have plenty of on-board memory, you can run full blown VPN thru them and with the Tomato firmware, you have a lot of control over the configuration parameters.
I recently set one up for use in my camper. I haven't tried it out yet but the idea was to put the Flex in the back and tucked out of the way. Then use the Maestro from anywhere I have wifi back to my Linksys router. I'm hoping to be able to sit out under the awning in the shade and play radio! We do a lot of dry camping so I've put solar panels on the roof and run everything off of 12v dc. No noise at all from anything. The low low noise floor while out boon docking is pretty amazing.
Got to go - 6 meters is open again today!
