First, why are you using a wifi dongle, and not using the built in wifi?
RPi B+ doesn't have built-in WiFi.

I think its far more likely that he is actually running a 3 B+ and just left off that character in his post, I find it difficult to believe he's still messing with a RPi 1 B+, that is basically 5 years old at this point in time.

I mean, if you are running a RPi 1 there really isn't a valid reason to bother with the 4.0 or 4.1 beta unless you just want to play with it (a Rpi Zero W user reported that 4.1 and 4.0 is noticeably slower), but if you are running a 3 B+ it is mandatory.

Hopefully he'll clarify.

I am using a wifi dongle because the Pi b+ does not have built in wifi. As to why I am using a Pi B+ I have two Pi zero hot spots and have a B+ for which I have found a use for and which works perfectly well as speed is not essential with Pi-Star,.

While you are correct, speed and multiple cores make a huge difference.

Here are some times I gathered for how long it takes for a system service to start and complete.

Code: Select all

RPi Zero W
nextiondriver.service (6.454s)
mmdvmhost.service (5.695s)

RPi 3B+
nextiondriver.service (102ms)
mmdvmhost.service (724ms)
a RPi Zero W runs at 1000 Mhz, a RPi 1 runs at 700 Mhz stock. So you are 300 Mhz slower than a RPi Zero W, so your service times are even longer.

You should just go back to running pi-star 3.4.17 or spend 10 bucks and use a RPi Zero W, it just isn't worth it for how cheap these things are.
That link doesn't show a known issue, it shows one user that didn't configure wpa_supplicant.conf correctly.

I guess Toshen was right after all. XD Shaking my head.

When Andy released 4.0.0, he mentioned that it was designed to work on all RPi models: "I even tested it on the Original Pi A (256MB RAM), it even works on that." As far as I have seen, he never said anything different about 4.1, so I'm guessing that it should work on all RPi boards, too. It's true that older boards will be slower, especially when booting up or when applying changes (I even get impatient with the Zero W doing those tasks), but for routine use and as long as you're patient, it seems that the older boards should work.

The B+ is still being sold by retailers like Adafruit and Element14, and it's surprisingly expensive at $30, so I guess it's still considered a useful board.

To narrow down whether the issue is related to Buster, it would be interesting to test Pi-Star 4.1 with the B+ board plugged directly into the network via an ethernet cable, and also to test it with a different WiFi dongle.

But why would anyone spend 30 bucks on a RPi 1, when you can buy a 3 B+ or even a 4 B and get ~20x+ the performance, and a free built in dual band wifi. 8-)

It can't be related to buster cause he mentioned he noticed it on the 4.0 build, so thats why I recommended he just stick with 3.4.17. Maybe they deleted or changed the firmware for his wifi dongle. I know that was one of the things Andy had to add to 4.1 cause they moved a bunch of the firmware to a different package that wasn't included by default.

I dunno, he hasn't said what chip he's using for a wifi dongle.

I agree. But if I already had one (I don't), I'd probably want to see if I could get it to work.

Looking into Raspian Buster and using a wifi dongle it seems it is a known problem, may be a update will solve the problem.
I can't duplicate the problem here, John. Using an Edimax wifi dongle https://amazon.com/gp/product/B003MTTJOY/ on a

Code: Select all

$ cat /sys/firmware/devicetree/base/model
Raspberry Pi Model B Plus Rev 1.2
and Pi-Star:4.1.0-RC5 / Dashboard: 20190905, the wifi works flawlessly, switching easily between base, mobile and hangar SSIDs whenever needed.

An easy way to identify your wifi dongle is

Code: Select all

Just fer sh*ts n giggles I still have a original b model. I Use it with an old dvap when I need to shake the dust out of the dstar radios, Andy said it would work. jokingly I needed to check for myself. and it does, currently it's running rc4, I think. But it def.runing the new 4. With no issue. ImageImage
