Support TP-Link adapter TL-WN725N without powered USB hub

[oskar.norin]

Hi
Have search the net and this forum but can not find any definitive answer if TP Link adapter TL-WN725N will work without a powered hub?
Planing to buy one since it is so cheap but not sure if it will work. Ebay and other places sells this together with PI without any hub so that should indicate that is works but I like to get this verified before I buy one.

I have to say this is wired. I uses a EDUP adapter with RTL8188 just like WN725N but no powered hub required.

You may mod your board with 2 leads from microUSB input directly to the internal USB hub. But I am sure it's not something good...

Hi Oskar,
Hope is not too late, I just bought one of those last week and it's working perfectly without using a hub... just plug&play.
Tested in Raspian wheezy | Raspberry Pi model B.

Hi nikasio

Arrggggggggghhhhh. I have just spent about 5 hours over Xmas trying to get my new PI and TL-WN725N working together, but I cant get it to work (DHCP cant get an IP address offer)
See here http://www.raspberrypi.org/phpBB3/viewt ... 28&t=26975

Can you explain in detail what you did to get it to work please ? Thanks for your time

Hi Geoff.
Here are the steps:
1. edit /etc/wpa_supplicant/wpa_supplicant.conf like this:

Code: Select all

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
network={
        ssid="homenet"
        key_mgmt=WPA-PSK
        psk="MyPassword"
}

* I don't remember exactly the ctrl_interface_group I used, check if you have one already defined in the wpa_supplicant.conf and use it.
* I think in your case (WEP) you should use "key_mgmt=NONE" and "wep_key0" instead of "psk"

2. To test ir manually, you can do

Code: Select all

wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

3. Finally, if you want to connect on booting, edit /etc/network/interfaces and add

Code: Select all

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

4. Get new IP

Code: Select all

dhclient -r
dhclient wlan0

If it is plug and play why do I need to modify the config files?

It means that you dont need to install any driver ... its automagically detected but it cant read your mind. Thr wifi adapter doesnt know to wich network you want to connect or whats your password.
you can configure it graphicaly but in the back ... you are editing a file.
I prefered the command line.

Hiya

Thanks for the prompt and detailed reply. That would help greatly apart from one snag, I am using a wifi network with WEP not WPA. I dont know how to change that config setup to make it work with WEP not WPA ?

would anyone be able to answer that question please ?

Thanks for any help

Regards Geoff

[nikasio]

did you try configure wpa_supplicant to use WEP?
Something like:

network={
ssid="static-wep-test"
key_mgmt=NONE
wep_key0="abcde"
wep_key1=0102030405
wep_key2="1234567890123"
wep_tx_keyidx=0
priority=5
}

Why not login as user pi and use the WiFi-Icon on the desktop?
