The Huawei E3372 is quite a popular LTE stick: it’s widely available (in retail stores, on eBay and also in branded variations, eg. “Telekom Speedstick V”, “Megafon M150-2”) and rather affordable (currently starting at €60 in Germany). It features a LTE Cat 4 modem supporting up to 150 MBit/s download and up to 50 MBit/s… Continue reading Flashing a Huawei E3372h 4G LTE stick from Hilink to Stick mode
Here’s a small update to my post from last year on Dell Wireless 5809e support in Linux – a followup.
The Raspberry Pi Zero captivates with its small dimensions. This comes at a cost, however, with only one micro USB port available for peripherals of any kind. In this scenario you’ll probably think twice about what you connect to that port. “A USB hub” may sound like a natural choice but if you’re like me,… Continue reading Using your Raspberry Pi Zero’s USB wifi adapter as both Wifi client and access point
When looking for Wifi adapters, there are reasons why you would not just go ahead and buy whatever your favorite $DEALER has in stock. If you have some experience with Wifi adapters and drivers, especially under Linux, you’ll know that in general Atheros chips are what you want. They have a long tradition of both… Continue reading Market overview of USB Wifi adapters based on Atheros chipsets
In my earlier post on Complete rotation support for the Adafruit PiTFT 2.8″ capacitive touchscreen display I described that support for the touchscreen has landed in the mainline kernel in form of the ft6236 driver. I also described that my test program would work correctly now.
In my previous post, I introduced the PiTFT 2.8″ capacitive touchscreen display and showed some test code. If you played around with that, you might have noticed that with the default /boot/config.txt setting of rotate=90 the display is a landscape mode.
“We live in an age when unnecessary things are our only necessities” (Oscar Wilde, “The Picture of Dorian Gray”) Like many others, I bought another Raspberry Pi 2 to play around with, together with an Adafruit 2.8″ PiTFT capacitive touchscreen (note that Adafruit has various variants of displays that differ only in details such as… Continue reading Getting started with the Raspberry Pi 2 and a Adafruit PiTFT 2.8″ capacitive touchscreen display
On my Dell Latitude E7450 notebook I regularly update to current versions of the Linux kernel. Along with such a Kernel update my notebook’s SD card reader could no longer be initialized properly:
Here’s a followup on my previous post Dell Wireless 5809e support in openSUSE 13.2.
On recent SUSE-based distributions such as openSUSE Tumbleweed (and potentially also 13.2), executing iw reg get to check your WiFi device’s regulatory setup will likely get you an output such as this: global country 00: DFS-UNSET (2402 – 2472 @ 40), (N/A, 20), (N/A) (2457 – 2482 @ 40), (N/A, 20), (N/A), NO-IR (2474 -… Continue reading Fixing wireless regulatory support (crda, wireless-regdb) on openSUSE Tumbleweed
