Is Pistar supported on the Raspberry Pi 4?

Apparently so ... viewtopic.php?f=23&t=1906 using Pi-Star v4.1 rc3 after an upgrade from rc2 which can be downloaded at https://pistar.uk/beta/Pi-Star_RPi_V4.1 ... l-2019.zip

I'm running a ZUMspot on a RPi 4B (with a fan, because the 4B runs hot). Requires Pi-Star 4.1.x, which is a release candidate and has some issues, so you have to be prepared for some not-so-smooth sailing sometimes. (In particular, I run into issues with it not connecting to my WiFi network on startup and sometimes have to power off and off multiple times before it will at last connect, and I'm not the only one running into that issue. I could use an ethernet cable, but this is a test hotspot, so I'm just waiting for future updates/upgrades to fix the issue.)

The same happens to me with PI3 A +
I have to turn on several times until it works
WIFI Especially with cold start.

Returning to 4.0.0 rc4 without problems.

Yep, I had the same issue on a couple RPi 3A+ hotspots running 4.1 and have returned to 4.0.0=RC4, with which I get more stable results.

EDIT: Probably worth mentioning that I'm running an RPi 4B 4GB board in my shop as my computer, which connects to the same wireless network every time I start it up with no problem whatsoever, so I don't think it's an issue with Raspbian Buster.

I wouldn't think that the RPi 4 non-compliant USB-C issue would have anything to do with the wireless chip or its power consumption, but several people have indicated spurious problems with a power supply less than 5.2V/2.5A.

As an aside, for the past month I've been testing Pi-Star v4.1rc3 on a Pi2B DVMega D-Star/YSF/DMR with an Edimax ew-7811un USB wifi, and it connects effortlessly when moving between home, mobile and (once-weekly) restaurant wifi. I like the Edimax because the blue led gives visible wifi status.

I don't like the RPi4 because too much of its power requirement is used to generate heat.

I'm using the official Raspberry Pi 3A power supply, so no issues there.

You know Toshen, I think you are 100% on to something. I had a heck of a time trying to get a RPi Zero W connected to my network. Normally I always just use a wired connection but the Zero W doesn't have one. Lately I've been using the wireless only so that I exactly replicate the user experience and timing delays of the majority of people.

What I've noticed is 4.1 doesn't connect to a 5 Ghz networks at all. I can get it to associate and authenticate with my router which pulls a DHCP assigned IP Address, but when I ping it from another computer on the network, only one ping will respond, and then after that its completely unresponsive. When I try to access anything from the RPi over the wifi nothing works at all.

I can get 4.1 to connect to 2.4 Ghz networks, just not 5 Ghz. Its really odd.

I have tested 3 different RPi 3B+'s and a RPi Zero W. I have downloaded the latest raspbian images for lite and full desktop and installed those on SD cards and those images connect to my 5 Ghz network with no changes other than editing /etc/wpa_supplicant/wpa_supplicant.conf and typing in the ssid and psk. So there seems to be something that is different with the pi-star image. I don't know if Andy removing or installing a particular package broke things or what but I think it needs to be tested and the source of the issue identified ASAP.

Do you think we should create a new thread just to report this 5 Ghz network bug so it gets the attention it deserves? Go ahead and create one if you think so and I'll add my testing procedures and results there.

I've been thinking about reporting this as an issue; however, I haven't yet figured out the pattern. The issue I experience is different from the one you're experience as I always use the 2.4 GHz option. Since I have now heard from several people that they're having WiFi-related issues, I thought again today about reporting the issue in a new thread, but when I just now fired up my ZUMspot + RPi 4B hotspot running 4.1.0-RC3, it connected on the first try (of course!). So I'm still not spotting the pattern.

All I know for sure is that I have encountered this issue on several hotspots. The other ones were using RPi 3A+ boards running 4.1.0-RC2 or 3. I've since downgraded all those other hotspots to 4.0.0-RC4, with which I have no WiFi problems, and I'm now waiting for development work on 4.1.x to start up again. Oh, and I also know that I don't have any WiFi issues with my RPi 4B that is running Buster.

So I'm still in a wait and see mode on this one.

Weird. What speed/mode/bandwidth is your 2.4 Ghz network? What brand/model router?

thats another thing that is throwing me for a loop. I've spent the last 3 hours comparing the outputs of wireless setup commands between pi-star and the raspberrypi.org image only to find them reporting exactly the same results.

I guess I need to compare packages between them and then look and see if the ones Andy removed or installed have anything to do with the wireless network.
