I have an old rapsberry Pi B+
Your current kernel revision = 3.12.35+
Your current kernel build = #730
upgrading the kernel would be my recommendation.
As safety net using a cloned SDcard, so going back to the original version in case of unsurmountable issues is easily achieved

MrEngman,

I'm looking through the HUGE post and it's the only close to one driver that I "think" I need. Any assistance is appreciated. Here's my issue.

I have a (Netgear brand) RTL8188EUS 802.11n Wireless Network Adapter that i am using in conjunction with other adapters to learn more about channel bonding.

Oddly enough it worked with my older Raspian 8 OS then I did a clean install of Raspian 9 (Dec 4, 2021) and now it will not work BUT...I see it :?

I have a TXT of my lsusb -v output (not allowed to attach it so it's below) and I can see the interface in there. I "think" I need to load the driver for it but don't know why I would have to do that for a newer OS and not sure where to begin.

I have tried just about all the other easy things that I the Google could show me like 'sudo ifup' & 'ifdown' and many others but still NOTTA! :cry:

Here is the output from "ifconfig":

Re: (UPDATE) Drivers for TL-WN725N V2 - 3.6.11+ -> 4.xx.xx+

Hi @MrEngMan,

A quick question if i may re an issue with an Alfa AWUS036ACS USB WiFi Adapter not seemingly working properly.

I have used your script to install the drivers needed which as everyone is saying worked great, so kudos for that. The driver installed for the adapter is the 8812au one.

The problem i have is i need the adapter to work in monitor mode which looking at specs and other forum posts the Alfa card does support. The Alfa card runs chipset - Realtek RTL8811AU

I have an older adapter i use on the same build which is an Alfa AWUS036NEH, this is only 2.4 Ghz hence the swap to the new Alfa 36ACS as this also supports 5 Ghz.

I'm using a RPI 4 2Gb board, my kernel version is 4.19.75, Rasbian V10 / Buster, my USB WiFi adapter is wlan0. The onboard WiFi interface is disabled.

I have a pre built system that uses TCPDump to capture WiFi frames which works great with the Alfa 36NEH. When i boot up with the old adapter inserted, the system loads the interface in monitor mode by default and i get lots of frames captured.

When i plug in the new Alfa card ( 36ACS ) it is still detected as wlan0 ( post install of your script ) but i have to manually down the interface and change its mode to monitor This is no problem as i'll automate that later on.

The issue i have is although everything says its monitor mode its not capturing any packets.

The output of ifconfig is -

Code: Select all

wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        unspec 00-C0-CA-AC-44-73-30-30-00-00-00-00-00-00-00-00  txqueuelen 1000  (UNSPEC)

        RX errors 0  dropped 704  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 3 overruns 0  carrier 0  collisions 0
The output of iw dev is -

Code: Select all

phy#2
        Interface wlan0
                ifindex 5
                wdev 0x200000001
                addr 00:c0:ca:ac:44:73
                type monitor
                channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz
                txpower 18.00 dBm
normally when i run the system with the old Alfa card, ( 36NEH ) installed the RX packets increase every time i run the command, with the new Alfa card i dont get any packets received at all.

Not sure what else to try, any suggestions ?

Thanks

** Quick update, upgraded to kernel 5.4.79 and still have the same issue.
