There is a greater potential for USB devices to cause interference with USB 3 on the 2.4 GHz band. If you are experiencing performance issues with wireless devices we recommend inserting a USB hub or USB extension cable to put some distance between your USB devices and the computer or otherwise disconnecting USB devices to see if the situations improves. While we have USB extension cables and USB hubs these items are not listed as stand alone products in our catalog. Feel free to contact us about purchasing these items.
If you would contact us about a networking issue with a wifi card please provide the output from the following commands (if you don't know how to open a terminal and run commands from a terminal let us know.. we can walk you through it if you can provide us with the name of the distribution and version your using):
If you're connecting a USB wifi adapter plug the card in and then immediately run the following commands:
lsusb
dmesg | tail -n 35
iwconfig
ifconfig -a (on newer systems like Debian 9 use "ip link show" instead)
ls /lib/firmware
uname -a
cat /etc/*-release
rfkill list (on newer systems you may need to install rfkill first via "sudo apt-get install rfkill")
If your wifi card shows up with iwconfig run:
sudo ifconfig [wlan0] up
Note: Replace above command with "sudo ip link set [wlan0] up" on Debian 9 and other systems with ip rather than ifconfig. See ifconfig vs ip comparison for details.
sudo iwlist [wlan0] scanning
* Replace wlan0 with whatever wifi card it is your testing (hint: look at the iwconfig output)
If your connecting a PCI wifi card then run the following commands and attach the output of the dmesg.txt file that is created and email support at thinkpenguin com:
lspci
dmesg > /tmp/dmesg.txt
iwconfig
ifconfig -a (on newer systems like Debian 9 use "ip link show" instead)
uname -a
cat /etc/*-release
rfkill list (on newer systems you may need to install rfkill first via "sudo apt-get install rfkill")
If your wifi card shows up with iwconfig run:
sudo ifconfig [wlan0] up
Note: Replace above command with "sudo ip link set [wlan0] up" on Debian 9 and other systems with ip rather than ifconfig. See ifconfig vs ip comparison for details.
sudo iwlist [wlan0] scanning
* Replace wlan0 with whatever wifi card it is your testing (hint: look at the iwconfig output)
Then email support or support at thinkpenguin com.

General Network Troubleshooting Procedures
If you are connecting an external USB wireless adapter and having trouble with an internal wireless card here is how to disable the internal card without removing it (applies to Ubuntu and similar distributions)
First get the bus ID of the internal PCI wireless card that you would like to disable by running the following command:
realpath /sys/class/ieee80211/phy0 | cut -f 6 -d '/'
Then create a rules file with the nano text editor containing the disabling code:
sudo nano /etc/udev/rules.d/81-wireless-pci.rules
The below code is what needs to be copied into the rules file. In both places below replace "0000:03:00.0" (bus ID) with whatever the output of the realpath command above was.
ACTION=="add", KERNEL=="0000:03:00.0", SUBSYSTEM=="pci", RUN+="/bin/sh -c 'echo 1 > /sys/bus/pci/devices/0000:03:00.0/remove'"

Did you purchase a router with a 'non-functional' configuration? See our simpler reset instructions here.
To reset TPE-R1100 Mini VPN Wireless Router (if you forget the password): Connect power to Mini VPN Router, wait for lights to blink, then hold reset button down for 10 seconds. This should reset the device and no password / VPN configuration will exist on reboot. After performing a reset any PenguinVPN configuration you had will be lost. To setup PenguinVPN service again follow the instructions below:
Switching Between Booting From the NAND and NOR libreCMC images on TPE-R1200 routers: 1. Open a terminal and run "ssh root@192.168.3.1" 2. Enter the command "fw_setenv bootcount 3" to boot from NOR or "fw_setenv bootcount 0" to boot from NAND 3. Run command "fw_printenv" to see the status

Did your USB wifi adapter stop working after applying security updates? For the TPE-N150USB & TPE-N150USBL wifi adapters there was a kernel regression in 5.4.47 (also affects 5.7.3+, including 5.7.6) that should be reverted shortly, but until then here is a temporary resolution:
This issue is known to impact Arch & probably other rolling releases as well as Fedora 32 & Tails 4.9 at the moment (July 28th of 2020). Sadly there is no simple work around for Tails, but the issue has been reported to Tails & upstream. The temporary solution to work around the issue on Fedora until the distribution releases an updated kernel fixing the problem is as follows:
1. Run the command below to find out what kernels you've got to choose from:
ls /boot/vmlinuz*
You'll see output something like this:
/boot/vmlinuz-5.6.6-300.fc32.x86_64 /boot/vmlinuz-5.7.7-200.fc32.x86_64
The older one will be the kernel version that works with your wifi adapter.
2. Then run the command below, but replace /boot/vmlinuz-5.6.6-300.fc32.x86_64 with the older version of your kernel as seen from running the command in step 1:
sudo grubby --set-default /boot/vmlinuz-5.6.6-300.fc32.x86_64
3. Unplug the USB wifi adapter and reboot... plug it back in after you boot the system back up and you should now be able to connect again
