Edimax ew-7811un v2 wifi ADAPTER support

I have bought Edimax ew-7811un for my two players which run RPI 4 4GB. The Moode 7.2.1 does not recognize the adapter and I found I had got the V2 adapters that have RTL8188EU. The V1 has RTL8188CU.
Does Moode support the above adapter? How could I get them to work with my players. Thank you

It should be simple: https://edimax.freshdesk.com/support/sol...spberry-pi Cheers, Phil

I followed the instructions but something is wrong with the installation. It does not work.

What does the Edimax give you over the built in wireless in the RPi4 that warrants the hassle?

I use this one:
https://www.amazon.co.uk/gp/product/B00J...UTF8&psc=1 It's a Ralink 5370 Wifi Dongle, and it worked straight out of the box - just plug in to Pi. I set integrated wifi adapter OFF in System Config. I found that the internal wifi was not totally reliable - perhaps location, or fact that Pi is cased with Allo Boss HAT. Anyway, the wifi dongle has worked a treat. Regards, Geoff

He used to maintain (still does I think) a nice script to run on your Pi that would check the kernel, and the adapter to see if there was a suitable driver for whatever chipset variant it reported, and then install it for you. I used it a few times successfully in the past when using cheapo noname wifi adapters that I had laying around. But, as pointed out above, if you have the already supported built-in wifi on your Pi - why not use that? Regards Adrian
I managed to install drivers and they work well now.
$ sudo apt install raspberrypi-kernel-headers $ ls /lib/modules/$(uname -r) $ wget http://downloads.fars-robotics.net/wifi-...371.tar.gz $ tar xzf 8188eu-5.4.77-v7l-1371.tar.gz $ ./install.sh $ sudo reboot As I use Argon 40 cases, internal WIFI reception is somewhat weaker. I wanted to try these as Comfast adapter cannot be found now. These work well and fit the cases well. Thank you for all your help. |
