Wifi adapter kills ethernet when plugged in? [Solved]

Mon Jan 27, 2014 3:47 pm

Hey. So I have been trying to create a wifi access point by bridging eth0 and wlan0. I did a clean install, and when I connect ethernet, I can ssh into the pi. However, plugging in wifi adapter along with ethernet somehow kills the internet connection through ethernet, thus I cannot ssh into it. This was using the default /etc/network/interfaces. The only way I have been able to get it working is to modify the /etc/network/interfaces so that both eth0 and wlan0 are getting ip from dhcp. The problem is, I need to setup my network interface as shown in these tutorials:
http://blog.sip2serve.com/post/48420162 ... cess-point
http://www.daveconroy.com/turn-your-ras ... s-chipset/

Both tutorials give different methods of setting up the network interface, however neither of them work for me. After plugging in the wifi adapter and powering up, I get no internet whatsoever. Is there any reason why?

Wifi Adapter: Realtek Semiconductor Corp. rtl8188cus chipset

Thanks

Thanks for the reply. I purged ifplugd, but still internet cuts off after I plug in wifi adapter. I currently have a clean install of raspbian and did apt-get update and upgrade before purging ifplugd.

Is it possible your power supply is not supplying enough current to power the Wifi Adapter? I read, one amp is required to power everything including the Ethernet.

Thanks for the replies. I was using a 750mA supply before, and after switching to a 2A supply, everything worked perfectly. Thanks for the help guys.

I did this, assuming it was good information. All it did was kill
the lan connecton. I no longer can get on the internet with my
LAN ethernet cable. It disappeared the connection.
What the hell kind of help is this?????????????????????

you should at least give me a way back so the ethernet
would work. Now I got zip

Thanks for nothing,

You should be able to re-install ifplugd using sudo apt-get install ifplugd
