Re: LAN or Wifi - nogo

Speed Test Pi3b+ vs Pi4b4 : LAN + USB HDD

I have an old 2.5 inch Seagate 320GB SATA hard drive. Since it is rated at 5V 0.451A I decided to test the Pi3B+ to see if it would boot without SD Card and without a powered hub but using a USB3 to SATA cable. I was researching SSD drives and they all seem to be rated for higher Amps. I downloaded ...

Re: When are people in the U.S. getting their Pi 4s?

I got lucky. On Tuesday I saw that Micro Center had the 1 GB and 2 GB in stock. I reserved a 2 GB on Tuesday and went to pick it up on Wednesday. While I was waiting for the clerk to get my order from the back room I noticed a box on the "return to stock" shelf. I asked about it and it turned out to...

Re: Headless set-up of Raspberry Pi 3 B+

Should I assume that I cannot access my Pi through cable? I did the SSH thing but I haven't tried seting it up through Wi-Fi. Only through cable. I had trouble with networking on the newest version of Raspbian. You may be having the same problem but it is hard to tell if you do not have a display. ...

Re: Setting static IP address on a Pi 4

Yes, Raspbian Buster Lite. dhcpcd returns sending commands to master dhcpcd process At least you did not get an error like I did. You might want to try this command line to see if this works. sudo dhcpcd -4 -S ip_address=192.168.11.210/24 \ -S routers=192.168.11.254 \ -S domain_name_servers=192.168...

Re: Setting static IP address on a Pi 4

Maybe I should follow the second solution here, which involves disabling the DHCP client on the Pi ? https://raspberrypi.stackexchange.com/questions/37920/how-do-i-set-up-networking-wifi-static-ip-address/74428#74428 Are you using Raspbian Buster?

Re: Is starting with a 3B+ a bad idea now that the 4b is out?

They are so cheap, get one of each.
I have two 3b's, one 3b+, and two zero w's.
My next one will be a 4GB Pi 4.
You could decide for now based on the type of HDMI cable and power supply you currently have.
But I predict that you will want a Pi 4 soon enough.

Re: Raspberry Pi 3 Model B V.2 doesn't have any channels

I had a network problem with Buster on my Pi3b+.
