Macbook M1 Accessories

The M1 Macbook has only an audio jack and two USB C ports, so a dongle was a necessary expenditure. I ended up buying the model shown in Figure 1. It only cost about Rp300,000 or A$30, so certainly not expensive. It was bought online of course. In a store, it would have cost twice as much.

After clipping it in securely, it is working fine. I tested it out by inserting a memory card. However, I left it connected overnight and noticed a significant drop in the battery percentage. The problem is that the dongle lights up in blue when inserted which is useful in a way but it also drains the battery. I don't think there's any way to disable the light, so it's only to be inserted as needed. I have a USB 3 card reader with USB C connector so I can use that where memory cards are involved and it doesn't draw any power. For HDMI output however, I'll need the dongle.

So far I've downloaded VLC for playing movies, Calibre for my ebook library, Chess X for playing and analysing chess moves and SageMath for mathematical investigation. Most of the work I do is done within the Chrome browser.

MIcro SD Cards

Having bought a 128 GB micro SD card, I could not find an adaptor to insert it into, even though I knew I had some laying around somewhere. In the end, I ended five of them online (the smallest number that could be purchased). Unfortunately, the SD card reader on my laptop doesn't recognise the card and two old USB 2 card readers that I found where also of no use. I'll purchase a USB 3 card reader and hope that does the job.

The reason for my purchase is that I want to store my Calibre e-book library on a storage device other than my hard drive. When my laptop crashed after updating Linux Mint, I lost all the data on my hard drive and even though I had a backup on an external hard drive, it was sadly out of date. It was quite a tedious and slow job to back up the library which is why I procrastinated in doing it. 

The SD card, even with the adaptor, is more compact than a thumb drive and can sit less obtrusively in my USB hub that currently hosts a fan and a dongle for my mouse. There are two slots left. My laptop has two USB 3.0 ports, one hosts my TP-LINK WiFi dongle and the other hosts my USB hub. 

It would be nice to have everything working on my laptop but that it's nearly 11 years old now I can't complain. Currently my Elementary OS that I have installed doesn't recognise the internal WiFi card, the webcam or, seemingly, the SD card reader. Nonetheless, I'm happy with the current performance of the laptop.

WiFi and Elementary OS

Since installing Elementary OS on my 2013 MacBook Pro, I had been using a wired connection and only recently noticed that the operating system was not recognising the wireless card in my laptop. I tried a few suggested solutions online but nothing worked. However, I found an old USB WiFi dongle that simply worked.

I was curious to find out more about this venerable dongle so I asked Gemini:

What can you tell me about the year of manufacture and other details of the TP-LINK USB dongle with identification TL-WN322G+?

Identifying the exact year of manufacture for a specific TP-LINK TL-WN322G+ USB dongle might be challenging due to the lack of individual tracking on each unit. However, I can provide you with some general information about this model and suggest methods to determine its approximate age:

General Information:

• The TP-LINK TL-WN322G+ is a wireless USB adapter that supports 802.11g Wi-Fi connectivity with speeds up to 54 Mbps. 

• It was first introduced in 2008, making it a relatively older model compared to newer Wi-Fi standards like 802.11ac and 802.11ax. 

• It's a budget-friendly option for basic internet connectivity needs and is not ideal for demanding tasks requiring high bandwidth.

Given that our Internet router is pretty ancient that's hardly a problem. I asked the following question:

What WiFi standard came before 802.11ac and 802.11ax?

The WiFi standard that came before 802.11ac is 802.11n, also known as Wi-Fi 4. It was introduced in 2009 and offered significant improvements over its predecessor, 802.11g, in terms of:

• Speed: Increased maximum data transfer rates of up to 300 Mbps compared to 54 Mbps for 802.11g. 

• Range: Improved signal range and stability. 

• Multiple-Input, Multiple-Output (MIMO) technology: Introduced MIMO technology, which utilizes multiple antennas to transmit and receive data simultaneously, further enhancing speed and reliability. 

• 802.11ac, also known as Wi-Fi 5, came after 802.11n in 2013 and offered even faster speeds (up to 1.3 Gbps), wider channels, and improved beamforming technology for more efficient data transmission. Finally, 802.11ax, or Wi-Fi 6, arrived in 2019, bringing further advancements in speed, efficiency, and capacity to handle the ever-growing demands of modern wireless networks. 

So here I am with my 2013 MacBook Pro and my 2008 WiFi dongle connected to rather dated wireless router. I thought I'd find out more about this router:

What can you tell me about the HUAWEI EchoLife HG8245A wireless router?

The Huawei EchoLife HG8245A is an optical network terminal (ONT), also known as a fiber optic modem router,  designed for home and small office/home office (SOHO) users. It utilizes GPON technology to provide high-speed internet access through fiber optic cables.

Here are some key features of the Huawei EchoLife HG8245A:

• Supports GPON technology: Delivers fast and reliable internet connectivity through fiber optic cables. 

• Wi-Fi connectivity: Provides wireless networking capabilities with support for 802.11b/g/n standards, offering speeds of up to 300 Mbps. 

• Wired connectivity: Includes four Gigabit Ethernet LAN ports for connecting wired devices like computers, game consoles, and smart TVs. 

• Additional features: It also has one Phone (POTS) port for connecting a landline phone, and one USB 2.0 port for potential future uses.

Here's a table summarizing the specifications of Huawei EchoLife HG8245A:

Feature Specification

• Technology GPON 

• Wi-Fi Standard 802.11b/g/n 

• Wi-Fi Speed Up to 300 Mbps 

• Ethernet Ports 4 x Gigabit LAN 

• Phone (POTS) Ports 1 

• USB Ports 1 x USB 2.0

Overall, the Huawei EchoLife HG8245A is a suitable option for users who require a reliable and basic fiber optic internet connection for home or small office use. However, it's important to note that the Wi-Fi standard it supports (802.11n) is an older standard with limited speeds compared to newer options like Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax).

If you prioritize high-speed Wi-Fi for activities like online gaming, streaming high-definition videos, or transferring large files, you might want to consider a router that supports newer Wi-Fi standards.

I tried to find out the year of manufacture of this modem:

What year was this wireless router from HUAWEI released?

Unfortunately, I couldn't find a definitive answer about the exact year the Huawei EchoLife HG8245A was first released.

While I looked through various resources including product pages, press releases, and technology news archives, the specific launch date wasn't readily available.

However, based on the information gathered:

The router supports the 802.11n Wi-Fi standard, which was introduced in 2009. This suggests the HG8245A was likely released after 2009, but an exact year is difficult to pinpoint.

It's also helpful to consider the release dates of similar models from Huawei. For instance, the Huawei EchoLife HG8120, a predecessor model, was released in 2008. This might suggest the HG8245A came out sometime after 2008.

Therefore, while I cannot confirm the exact year, it's safe to assume the Huawei EchoLife HG8245A was released sometime after 2009, likely in the early 2010s.

Installation of Linux Mint 20.3

You can't say that there's no technological excitement in my life. I finally had to abandon the use of Ubuntu on my 2013 MacBook Pro. The keyboard, trackpad and mouse freezes were becoming too frequent and numerous reboots were required to activate these devices. Finally no amount of rebooting could activate them and so I turned to Linux Mint.

The installation went smoothly enough but the boot up process was, and continues to be, interrupted by a series of error messages. That is a minor irritation but far worse was to come. I discovered that the OS didn't recognise the WiFi adapter in the laptop. So, for the moment, no WiFi but thankfully I have an Ethernet connection. I had an old TP-LINK WiFi dongle that must be at least a decade old and I tried that out but no luck. Perhaps a can buy a more up-to-date dongle that works. This is a matter for deeper investigation but for the moment, as long as the keyboard, mouse and trackpad don't freeze up on me, I'll be happy.

 

 

My initial attempt to install the Chrome browser failed but then I was reminded that flatpak is built into Linux Mint and, by using that, the installation of the Chrome browser and also Calibre was straight forward. So far, after a couple of days of using Linux Mint, I've had no problems and I hope things stay that way.

I've put out a request for help on the Linux Mint Forums and hopefully help will be forthcoming. So far 20 views but no comments. However, it's been up less than an hour. 

I'll add an addendum if help arrives.

ADDENDUM

... and help did arrive! A user called sleeper12 offered two suggestions. The first was:

inxi -Fxxxrz && rfkill list && iwconfig && mokutil --sb-state 

This had no effect but the second suggestion did the trick:

sudo modprobe -r wl && sudo modprobe wl && sudo systemctl restart network-manager.service 

This is great news and my laptop is now fully functional, apart from the webcam that I assume is still not working. I should ask for help with that on the forums as well.
