Raspberry Pi 3B+ Network Speed

Time to see how fast Raspberry Pi 3B+ gets

The new board has been announced yesterday, and the courier dropped the new Raspberry Pi 3B+ about two hours ago. If you missed the livestream, I run some basic iperf3 tests to see how the new board stacks against the older model. I thought it would be a good idea to summarise the stream with some data. This is what you should expect from Raspberry Pi 3B+ Network Speed this time. If you want to read more about the other boards until the new test is ready – check this page.

Raspberry Pi 3B+ Network Speed

After initial troubleshooting (don’t use SD-cards from RPI3B as they won’t work) I managed to get the new board online (headless).  Remember to run:

sudo raspi-config

and set the WiFi locale, otherwise, you won’t be able to connect via 2.4GHz or 5GHz network.

I run two Raspberry Pi 3B+ Network Speed scenarios, making sure that both boards are subject to the same conditions.

Raspberry Pi 3B+ Network Speed (Ethernet)

Both boards are connected to the switch, and then to Linksys WRT1900ACS router, the iperf3 server is running on my Windows 10 machine. The entire network is wired to a 1Gbit standard. Only Raspberries could be the bottlenecks here.

As you can see The new Raspberry Pi 3B+ is 3 times more potent than its predecessor averaging 324Mbits/sec versus 94.5Mbits/s. I’m not very surprised as this is what we should expect from the announcement. I’m happy that this is the case.

Raspberry Pi 3B+ Network Speed (WiFi 2.4 GHz)

Since both boards are equipped with 2.4GHz networks, it was only logical to run the same test using WiFi. The boards are about 2m from the router, oriented in the same way. Here are the results:

I’m surprised to see such a big difference in the performance! Both boards are running the same 2.4GHz WiFi and the Raspberry Pi 3B+  averages 81.9Mbits/sec while the older sibling struggle to keep up at 34.6Mbits/sec.

Raspberry Pi 3B+ Network Speed (WiFi 5.0 GHz)

Since the Raspberry Pi 3B comes with 5G WiFi support – I wanted to see how much faster it could get. The results are little surprising:

Turns out the speeds are not improving anymore. Is this something that is going to be addressed via patch? Time will tell. I will test the latest Raspbian across all my boards and write a proper Raspberry Pi 3B+ Network Speed Test.

Conclusion

I was about to buy a Gigabit compatible board to run a VPN server, but it looks like don’t have to. The Raspberry Pi 3B+ is still in stock at the time of the writing so if you are in the UK, you might be able to grab yours! Follow me if you are interested in how the new board performs as a VPN server or a NAS drive!

How to use Raspberry PI as WOL (wake on lan) server

0
While you could wake up your PC from a mobile directly, having a dedicated server capable of doing so is the best solution. The reason is simple. You can hook up as many devices as you wish with a single endpoint. This is why Raspberry Pi is perfect for this.

Slow Internet Warning

From time to time my Internet grinds to a stop. Since Raspberry Pi 4 comes with a 1Gbps Ethernet, I decided to take advantage of it and create a reporting system in NodeRED that will monitor and report when the ISP is not keeping the contractual agreements. Works with Alexa, Google Home, Android and Windows 10.
