Hello, I have a tp-link tl-wn722n and I'd like to add it to my netgear WNDR3700's usb to act as a wireless client (WWAN). Right now the neatgear's 2.4ghz is acting as a client and the 5ghz as the actual wifi network. I want to substitute the wifi with the usb wifi adapter, but I don't know how.
Can anybody point me to the right direction?
Thanks!
You should be able to just install the driver and reboot.
https://wikidevi.com/wiki/TP-LINK_TL-WN722N_v1.x
https://wikidevi.com/wiki/TP-LINK_TL-WN722N_v2
https://wikidevi.com/wiki/TP-LINK_TL-WN722N_v3
also do
cp /etc/config/wireless /etc/config/wireless.original
rm -f /etc/config/wireless
wifi config
wifi
reboot
and enable the new radio1 in web interface
ver 1.x after loading driver still could not use it as a mesh
Could not find driver for ver 2.x of the adapter
Thanks both, I have the v2 version 
anyway there is a linux driver
https://www.tp-link.com/us/download/TL-WN722N_V2.html#Driver
anything I can do?
Operating System: Linux Kernel 2.6.18~3.19.3
Version 18.06.1 uses 4.9 and 4.14...it would likely need patching.
Is this something I could do? With some help of course... If this is the case, can you pont me out where to start or some tutorial/documentation to read?
Or does tp-link has to provide the updated driver? Meaning I should use the usb stick somewhere else (
or 
)
Have you tried kmod-rtl8192cu?
It should also support RTL8188, maybe it needs to be patched to include the TP-Link VID/PID of your adapter.
sorry can't help I've got version 1
In theory, the rtl8188eu should be supported by kmod-rtl8xxxu, maybe your usb card is supported by this driver
thanks @s_2 & @Mynzer I'll try it!
How can I install and enable the packages you suggested? via opkg?
If you're using LuCI, go to System -> Software, Update package lists and search for kmod-rtl8192cu.
Using the shell it would be:
opkg update
opkg install kmod-rtl8192cu
OK installed, dmesg shows

Next step should I followd @markbirss advices, but no new interface is shown (already had radio0 and radio1: 2,4 and 5 Ghz of same interface)

Where should I go next?
ok, seems your driver not match usb device?
as it should have added a radio with option path on USB:///:///
do this
opkg update && opkg install usbutils
lsusb -t
lsusb
want to see what usb wifi you actually have
lsusb -t

As I posted before there is no Openwrt driver that supports this USB adapter.
:(((((
thankyou anyway for your time and support
Curiously there is a package rtl-8188-eu-firmware available, containing the binary blob to operate the device.
But the driver itself has apparently not yet made it to the master branch:
There is someone that got working the TL-WN722N V2 on Fedora using rtl8xxxu driver, in theory should work on OpenWrt too
To install kmod-rtl8xxxu, first uninstall kmod-rtl8192cu, on shell use
opkg remove kmod-rtl8192cu
reboot
Then install kmod-rtl8xxxu using the same procedure suggested by @s_2
Using LuCI, go to System -> Software, Update package lists and search for kmod-rtl8xxxu.
Using the shell it would be:
opkg update
opkg install kmod-rtl8xxxu
reboot
