My pi is running in my shed, quite a distance away from my house. It's working but I thought I would try and improve its wifi signal by purchasing a high-gain wireless adapter. I'm having a nightmare trying to install it though.
The output of usb-devices
is the following:
T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=480 MxCh= 0
D: Ver= 2.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=2357 ProdID=0120 Rev=02.00
S: Manufacturer=Realtek
S: Product=802.11ac WLAN Adapter
S: SerialNumber=00e04c000001
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=500mA
I: If#=0x0 Alt= 0 #EPs= 6 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
So it's appeared to have found the device and can identify it, but it's not appearing in ifconfig
. I just get eth0
, lo
and wlan0
.

There are two things I am having trouble with:
- Getting the adapter to appear as
wlan1
- Once it appears telling the pi to use
wlan1
over the defaultwlan0
I'm running Raspbian 10 (buster).
Things I've tried
- Spent a long time trying to compile the driver, but since
usb-devices
shows its there I shouldn't have to do that should i? - Tried editing the
/etc/network/interfaces
to whats outlined here USB WiFi adapter being detected but no connection - didn't work.
ip -br link
. Do you find wlan1, maybe DOWN? – Ingo Aug 20 '20 at 08:37usb-devices
you only see the raw usb device that can be supported by a driver, so you have to load the correct driver. Look atjournalctl -b
if you find something about firmware or driver or realtek. – Ingo Aug 20 '20 at 11:02journalctl -b
