What is the main difference between running say…3 dongles on a desktop vs 3 dongles and raspberry on each dongle?
Basically why raspberry when some people can achieve this with 2-3 dongles and get the proxy on a desktop and run JV. Instead of buying a raspberry for each one.
Just a little confused and I am using a VPS so don’t know if that applies the same.
If your router supports it yes! Again a decent router which support 3 dongles or more is in my country not a cheap solution, I don’t know about yours.
But again on rasperry you are able to create proxies and use on client phones too. This you can’t on routers.
But if you want a basic setup yes your suggestion is doable. Yet if you wanna scrape all costs you can get a usb hub, plug it to the wall and do your work.
The only benefit with rasperry is that it works like a tiny computer.
The USB hub is just a dummy in this case.
Be more concerned and invest just a slice more in some good LTE usb dongles, as these play a major rule. Buy Huawei if you can as I tend to have good experience with these.
This one for an example:
HUAWEI E3372h LTE
A bit pricey but stable! You may have kick as 4G provider, but with unstable hardware it’ll give you headache.
