A PCRE internal error occured. This might be caused by a faulty plugin

====== Setup WiFi adapter on Raspbian Wheezy ====== - Run apt-get update to get it up-to-date (not necessary, but...) - If you don't know what wifi adapter you are using you can find out - lsusb - In my case the response is: - ~ $ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.

If you have configured the raspi as DHCP, you will have to find the IP address it has been assigned. Simplest for me was do an nmap of my network to find it. If you configured it static, SSH to it as before. If this doesn't work, you may need to reboot it. At which point you can then SSH to it. ===== External Links ===== * [[http://www.raspberrypi.org/phpBB3/viewtopic.php?f=26&t=23401|WiFi hardware i/f discussion on Raspberrypi.org]] * [[http://www.ebay.co.uk/itm/290647056609?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649|USB WiFi adapter for sale on ebay]] * [[http://www.amazon.co.uk/USB-Wifi-Adapter-Raspberry-Pi/dp/B009FA2UYK|USB WiFi adapter for sale on Amazon]]
