Openspot 2 wifi radio issues

Post by nonseven » Sat Jan 12, 2019 11:10 pm

It seems like I might be having a problem with the wifi radio in my open spot 2.

First issue - my openspot 2 started developing an issue connecting or maintaining a connection to my wifi router (Apple AirPort Extreme) from a relatively short distance away (in another room, about 25 ft away). At first it seemed to work fine. So I moved the openspot 2 right next to my router - perhaps a foot away. That seemed to solve the issues for a bit. First time I saw the internet connection quality listed as "Ok." But now it's disconnecting from wifi sometimes. And the webpage interface (sharkrf link) intermittently disconnects, even though my computer network connection is excellent.

On the network tab of the web page interface, the "internet connection quality" goes from OK, to medium, to low, to unavailable and back to Ok, and so on.

My internet service seems fine with no problems, consistently showing results on a speed test of about 240mbps download speed, and 40mbps upload speed, and all my other wifi devices are not having any issues. My apple airport extreme shows the Openspot 2 having an excellent connection with a data transfer rate of 65mbps. No other signs of internet issues (I can stream 4K video, etc).

Question: Does the "Internet connection quality" shown on the web interface just measure the connection to the reflector currently connected to, or does it use some other criteria to measure the quality of the internet connection?

Internet connection quality is measured using a cloud server independent of the OS2's currently connected reflector/server. If the network latency is low, then the OS2 reports a good internet connection quality. Please note that even a high speed connection can have very bad latency. What you can try to do is to use Wi-Fi channels 1, 6 or 11 on your router and see if it helps. https://www.metageek.com/training/resou ... -6-11.html

Thank you for explaining how you measure the internet connection quality.
I'm consistently getting a latency (ping response ) of 17ms or less as tested from various devices. What concerns me more is the openspot 2 losing wifi connection while only being inches from the router. I'm not having this issue with other devices, including the OpenSpot 1 which I have reverted to.

Do you mean that the OS2 disconnects suddenly even if the network quality indicator on the Network page displays network quality OK and you don't touch the unit? What color is the LED when it disconnects? http://manuals.sharkrf.com/openspot2/en/led-states.html

The only time is disconnected and I caught it while looking at the internet connection quality, the quality had just dropped to low and then poor.

But then the OS2 announced it was no longer connected to wifi also. Confused me a bit - wouldn't the connection to my router be independent of the internet connection quality? At the same time, the web page interface was lost also.

My theory is that a wifi radio problem in the OS2 is the cause of both problems - bad internet connection via a failing wifi connection.

Low connection quality is caused by high latency which can be caused by low Wi-Fi signal. If you don't have issues with the audio stream then you can ignore low network quality.

Low Wi-Fi signal can be caused by interference on the currently used Wi-Fi channel (which is more prominent if the AP is not configured for channel 1, 6 or 11) and walls or high distance between the OS2's built-in antenna and the AP.

Please observe what LED state the OS2 displays when you experience a disconnect. What radio do you have? Have you tried the built-in local echo or the network echo? Do you have any issues with it?

I've got both a Kenwood TH-D74 and an Icom ID-51 +2, and use both with the OS2.

I'll do some more testing, and observe the LED status lights and the channel that the OS2 is connecting to on the wifi, when I have more issues.

Hey, have you found any resolution for your wifi issues? I just got my OS2 today and the one thing the seems to be an issue is the wifi radio or antenna. I have to be in the same room with my router and it works fine. I go just 30 feet away in another room and it just disconnects. Meanwhile i have other devices that show an excellent signal in the same room. Its really not that far away. If the wifi range is just limited, I’ll accept that, but I believe I may have a defective unit. Just wanted to know what is happening with your OS2. Im just looking for answers. If I have to send it back I will. The range just seems way too short for a 2.4Ghz radio.
