Re: wifi not working with edimax ew-7811Un

Post by ericbsd »

I have one USB arriving today. It is TP-Link Archer T2U V1 AC600 Wireless Dual Band USB Adapter, 2.4GHz 150Mbps/5Ghz 433Mbps, WiFi Dongle, Mini size. I will let you know how it goes.

I am waiting for the other one to arrive around Sunday.

To me both TP-Link Archer T2U V1 and V2 AC600 Wireless Dual Band USB Adapter and TP-Link Nano AC600 USB Wifi Adapter if they work properly they are better. They are both supporting 802.11ac so when the supports land on the kernel it will run even faster.

Recompille rtwn driver to support edimax ew-7811Un Version 2

Post by wb7odyfred »

Here is the changes made to the rtwn driver for OpenBSD source code.
http://openbsd-archive.7691.n7.nabble.c ... 01834.html

3 Files to edit in OpenBSD source code. See if you can find matching files in GhostBSD rtwn driver source code

We might easily edit in the USB Vendor/Product IDs to GhostBSD file rtwn_usb_attach.h There might be another couple places to edit other rtwn driver files to support this simple addition of 7932:b811 USB Vendor/Chip IDs EDIMAX RTL8188EU That should make driver if_rtwn_usb.ko support the Edimax EW-7811un V2 nano wifi usb dongle work by using the RTL8188EU driver section of the "rtwn" driver I was asking if someone could edit the file, compile, the driver, and attach the two kernel modules. Then others could test and debug if it works for them with the Edimax EW-7811un V2.

Yes, I understand, I cant volunteer a developer to do this task. I tried to do the research and share the information that would make it easy for someone to edit and recompile with out a lot of thought or effort. Working now to get my GhostBSD hard disk to boot back up, so that I might make this happen myself from own GhostBSD Computer installation.

So TP-Link Mini - AC600 USB 2.0 Wifi Adapter is working really well with good speed.
The other one does not work.

if anyone is looking to buy it make sure that it is an Archer T2U Nano.
